This Project is Sweet! Can you make me one?
Yeah, I can make you one. If you would like me to make you a rumble mouse, then email me at lipscgr@gmail.com, and I will discuss it with you.
*edit-Janurary 24, 2006* – I am really busy this semester in my second year of medical school. I won’t be able to make anybody a mouse until July of 2006. I will make one for $20 for the mods, which includes any parts. This would not include the price of a mouse or shipping.
Hey this is awesome! Can you tell me the exact parts list (transistor make, resistors etc. etc.)? (This for my “daily” trip to radio shack)
1 PNP transistor – 2N3906 (276-1604)
1 10K micropot – (271-282) – though, it is a little too big… maybe a 5k or 1k
1 PC board – ICB90 (276-0148)
1 Sanko Electric vibrating motor ( Sanko Electric # 1E120). Follow the link in the article. I doubt radioshack carries motors of this size.
Hey, trying this out. That’s wicked cool though!
Wicked Cool!
Bloody awesome
[...] My friend at http://www.zerosign.net made this, and it is a fun project. Who doesn’t love the simpsons? This would be nice if you had a large storage device, maybe a gig or so. You could store some mp3s on your homer drive. It appears that he designed his red LED to stay on all the time, but he could have also made it come on when he was accessing data. If he would have used the two usb pins in the middle, they are only active when data is being written to the device. He could have connected them through a transistor, much like in my rumble mouse product. But, he would have probably wanted a NPN transistor, rather than a PNP, because the NPN acts like a switch when the base voltage is high. I won’t rehash all of that, you can read about it in my rumble mouse section at http://www.diylive.net/?p=9. Here is the description he gave at dig(”MMmmmmm…data” Cool write up on the making of the first Homer Simpson USB storage device. 128MB of sweet, geeky goodness.) [...]
You got my vote. Keep up the good work.
Thanks man
In response to not being sure what it would be used for, think of the freshly mopped floors of shopping malls, the streets of your local suburb or perhaps in front of large groups of people. Interestingly enough, one of the main themes of the article focuses on how willing the general public was to commit a crime (vandalism, for instance), when their actions were not direct, but were instead buffered by a technological medium.
That is the part of the article that I did not understand. I guess that I just don’t understand vandalism, or demonstrations. I am thinking of a more practical use for the device. If it had more sensors, and the right program, it could be designed to paint the emblems in the center of a football field. Check out this video http://random-international.squarespace.com/pixel-roller-video
The same programming could be used to make this robot do a very similar thing. Of course instead of someone pushing it, you would have to make it all automatic
alright – i agree that the video you linked to is nothing short of amazing, absolutely mind-blowing, but… there is such a massive movement within certain communities right now to use this “combinatory” innovation that has been born out of the technological revolution for something that doesn’t just resort to coming up with another great Product. We’ve been there and done that and the world is falling apart – things need to be shaken, stirred – how is that NOT practical? I can think of a million brilliant uses for the techniques employed by the video you link to, but i fear you might have the same response to all of them. Thanks for the discussion. I didn’t necessarily mean to politicize this post…
Actually, I kinda enjoy the discussion. I would not say the world is falling apart. The world was here before I got here, and it is going to be here after I leave. I feel the purpose of technology is to make our lives easier, and to promote our well being. The purpose of the wheel was to enable a person to carry a heavier load. If you could build a robot that painted a needed emblem, that saves people the work of having to do it, but of what worth or value is there in illegaly painting a message on the side of the road? Someone is going to have to clean up the mess. I just don’t understand how a machine such as this painter is going to shake the world, and cause people to change.
you’re right -it won’t. Certainly not as much as it will shake the world if we just keep the purpose of its use within some acceptable use clause. I actually mean this with all sincerity, that wasn’t sarcasm. Technology IS that thing which shakes the world. Much more so than I could ever hope to counter with some stupid graffiti. To me, that’s all the more reason to fight.
Have you ever read Understanding Media, or the Guttenberg Galaxy? (both by Marshall Mcluhen) He talks about media (and thus technology) as an extension of our physical bodies “The evolution of weapons begins with teeth and the fist and ends with the atom bomb.”
So with each new technology, we have intensified our reliance on one of these extensions. I don’t want to stress the word reliance, though, because that’s not what I’m fighting against. It’s that reliance on one extension is the amputation of another. We are thrown off balance.
This is probably a bit too abstract to just throw into a conversation in which one side has been vying for specific and practical uses of what the other side wanted to remain Mythical in ability and power, but its interesting to think about.
dude, that is awesome. I’d pay $1000 to ride in that thing. really awesome…
Actually, I think you can pay to ride on it now. I will have to do a google search on it to find out.

You can, BoingBoing did a piece about it a while back. Costs a fortune though. You might be better off with the russians.
some of the mechanical engineers here at UK get a chance to use every now and then as part of a research project with NASA. unfortunately, I was not a mechE guy… i am jealous of ya…
I’m curious, why can’t you follow God and help people overseas by being an engineer? Designing an inexpensive computer, or coming up with a way to deliver electricity to small villages that have none, or a way to create drinkable water for people that have no access to good water? Or even designing the machines that doctors use in the field?
Just wondering…
That is a good question, and the answer is that I definately can. Engineering provides many numerous ways to help people. I guess to anwer the question. My brother is a physician, and I went on a medical mission trip to kenya once, and saw how we were helping the people. We saved the vision of this one baby, and I just felt God calling me into medicine. I am happy in medical school. I will forever be an engineer, and plan on using it any way possible. The reason I created this website is so that I could do the fun things I liked from engineering. I also wanted to be around it so I would not lose my skills. I guess I just did not see engineering as a career was fulfilling my purpose, but the skills it has give me can still be used. Does that help explain any?
Great project. You think your can bank a few EEproms together on a sitch so you can switch between graphics?
Thanks man, Yeah, you could absolutely have multiple EEproms. Another thought, which my brother-in-law did, was to use two rows of LEDs of different colors, connected to two EEproms, so you could have multiple colors in your display. It seems a waste to have 2 EEproms though, just to have multiple messages. You could prob. put two different sets of messages on the same EEprom. You are only using the the last 4 bits of an 8 bit eeprom (I may be wrong.. It may be even larger than that, I just don’t remember). Anyway, you could put bit 5, which is usually connected straight to ground, on a switch, so if you put it to positive, you would be selecting the next set of code. Everything would work the same, but instead of reading line 0-15, you would be reading lines 16-31 (with your new code). So by putting 2 programs on the same eeprom, you could have multiple messages. This could also be done for the other bits put to ground. You could have 16 different sets of messages if you wanted to.
Good Luck!
Thanks, that means a lot!

I did a post on that once. Check it out at http://www.diylive.net/index.php/2005/11/05/altoids-pocket-amplifier/
I do have plans for making a similar device later.
Cool, thanks for the link. Have a look round ipastudio.com. They have loads of projects like this. Great fun! Nice site, BTW. Bookmarked!
[...] 1. You can build amplified speakers for the Ipod (I will be doing this soon) 2. You can store all of your accessories in it.

That’s clever, very clever to put a USB port on a disposable digital camera, it just goes to shoe that almost anythink can be done if you know someone that can do it and have the idea in the first place.
woohoo… I have finals next week. Good luck Saturday.
Kick us some fresh projects when you’re done!
Thanks, Good luck to you also.
I found all the stuff for my line following robot, so I will post it a couple of days after I am done. Hopefully it will be good. Prob. by next monday.
Typo on my URL on my first post… dang comma key
His url is http://www.neodux.com, and is a pretty cool site so check it out. Hey GrendelT, if you are having hosting problems, then check out griffshp.com. It is hosted by a friend of mine, and he will give you good rates.
Very funny, i personally dont like IPods, but oh well

Hey you wouldn’t happen to still have those programs by any chance would you? It would be cool if you could post them up for soon to be calculus students
uhhmm… I may have some old programs on a TI-92. I will have to look, but it is at my parent’s house, and I won’t be there til after Christmas. Sadly, one day while at Auburn University, I was in a chemistry class, in the middle of a test. Actually I was a fifth year senior. (I had to go back and take fresman level classes when I decided to go to Medical School). Anyway, during the test, my calc froze. I took the batteries out, and the tiny memory battery was dead, so I lost all of my programs that I had worked so hard on. I was sickened. I will see what I have, and will be more than happy to post them. If there was something you really needed, I might be willing to program it for you, in return for something. We could work it out. Keep that in mind, but if I already have anything, you can have them for free.
If you want to really think outside the box (tin), you could remove the Ipod’s battery and put an Altoid in its spot. You know, for when you’re tired of music and your breath stinks.
congrats on finishing up finals! if your school uses NBME tests for the clinical rotations, then you might be in for another surprise since those things are wickedly hard. aside from that, 3rd year is quite rewarding. enjoy your X-mas break and thanks for the updates. i still have another week.
We do use NBME. We usually use them for our finals, except my micro class is lame, and they made their own final. Also, below 75 is failing in that class. Do you have finals? We can also make a D in my school. Anything below 75 is that. How lame. Anyway, thanks, and good luck to you Alan.
hey, i’ve been reading the site for a while but have never commented. just wanted to let you know i really like the projects and keep up the good work!

DIY Line Following Robot2
There you go, a fantastic DIY project that involved LEGOs, electronics, and robotics.
As any good engineering project goes, we will start out with a problem and a solution. The problem is going to be to build a Lego robot with sensors, …
hahah yea.. first time i had an ipod i did the same thing, well actually, first i thought it was broken because i was trying to click the center button and next button to get into menus, but it would scroll up and down, so i thought it was malfunctioning (i had no idea you navigated menus by ’scrolling’) then after i figured that out, i thought you were just supposed to leave it for a couple minutes so it would turn off automatically
To reboot the new iPod generation 5 (Video) you need to flip the hold switch on top on then off then hold play/pause + center buttons (Just thought I would throw that in there… it comes in handy when your iPod locks up.)
Hey, thanks for those good comments. Honestly, I don’t know what I did to reboot the ipod that I was playing with.
Hey! It’s a line sniffing robot, how cool. Getting enough coke wont be very cheap tho.. but cool anyway!
I remember last year someone came out with the idea of graffitti bike in NYC.There is a guy ridng his bike in New York and eveybody can send their message by cell phone SMS service.They were using chalk instead of can paint.
Will, I love your liller robot. I was think, I know its a bad thing at times, but can this be done with the LEGO Robotics? I’m going to get my set out and look at the software and see. I know I’ve build a line robot before. Keep up the good work.
[...] Link: Line following robot [...]
Its great to see new ideas on the horizon, this is a great idea and love it, what else will they come up with next, a sponge ship. lol
Excellent explanation of procedures and concepts. Extremely hard to find another engineer that can explain stuff in everyday language .
Thanks. I really enjoy doing this kind of stuff, and explaining how to do it. I am glad you like my stuff.
Greg
Yea, you can buy one of these on the TV for $14.99… 2 cars, and includes two “mats”… a city scape map, and a jungle scape map…
it follows a line drawn by a dry erase marker…
i was wondering where i could get that copper plated board for the diy circuit board?
You can get the board at radioshack. They have a double sided board for sure. I once got an entire kit from them that had everything that I needed.
[...] When surfing hack a day, I found this neat line following robot that uses LEGO bricks. What this person did was created a light sensor that will follow a black line. LEGO released a light sensor for their Mindstorms kit long ago, but for someone that doesn’t have an RCX brick and/or a Mindstorms kit, this is a neat, if not more technical way to make a sensor. This was the guys objectives: 1. Follows a black tape. 2. Upon reaching the end of the tape will pause for three seconds. 3. After pausing for 3 seconds will return back to the starting point. Pretty neat that it works! Click on the picture to view a video, and here. [link] [...]
This design has been floating around the ham radio circles for a while. It’s known in ham radio as the “St. Louis Switcher” for the city where the guy that came up with the idea lives.
If you need a ‘clean’ power source, this probably isn’t it, but for almost every general purpose, this is a great cheap solution…
Do you have any good ideas for a clean power source? I am interested in a power supply that does not have too much noise, that can be used for audio.
Not sure. I know you can make filter circuits to go inline for the power, just an RLC circuit I believe, but I’m not sure of any values of the components, or even how to design a filter for that use.
my AIM: GrendelT
Thanks a lot
that power supply mod from a pc PSU looks like a damn good idea, especially I have a couple 250-300W ones laying around that are still quite functional.
about the line following robot. i remember going to the Georgetown Toyota plant tour a few years ago, and they had robotic carts that brought up supplies and what nots to the different lines/areas. I’m almost certain they were line following robots and I was really impressed at the automation. A worker would press a button and the cart would go by itself and little would flicker in its path to alert anyone walking by.
we don’t have NBME until M3/M4. in those years, some rotations also have house finals. i guess it’s good practice for Step 2, but they are quite hard. anything under a 70 on a final for the M1/M2 years is “not passing” and you have retake a NBME one or retake the test. it’d be nice if things were honors/pass/fail. path/pharm finals were cumulative and evil. altho if I had a say one thing, it’s that knowing good solid path can really impress the attendings for rounds. wish i had known that.
[...] 10. The 5 v voltage regulator is a must, and is used to convert any 9v battery to the much needed 5 volts. This is used to power IC (integrated circuit) chips, as well as can be connected to a USB port to charge your ipod. The most common part is the 7805 chip, and here is the schematic. 9. Most projects require the use of an LED. This stands for a light emitting diode, and a diode only lets current go in one direction. It is important to put the LED into the circuit correctly or it won’t work. The longer lead is the positive lead, and must be placed in the circuit that way. theledlight.com gives an indepth tutorial on how to find the correct resistance values for different LEDs. Just remember the old equation V=IR (Voltage = Current * Resistance). For a nine volt battery a good 470 ohm resistor is a safe bet. Here is the simple circuit. 8. There are many times when a transistor is needed to be used as a switch. The NPN transistor can be used when the base is brought to a high voltage. The input current needs to be lower than the current through the collector (the top pin of the transistor). There is a 0.6 v drop accross the transistor, so the voltage accross the RB is going to be input voltage-0.6v. Go here for a more thorough explanation of picking the right resistor values. 7. There are many projects that require the use of USB, so it is important to know what the different pins of the USB are. 6. There is much need for a simple audio amplifier. There are many ways to do this, one is to use a darlington transistor like my 1-watt amplifier, and another way is to use an opamp like my post on the CMOY pocket amplifier, but the best way is to use an LM386 chip. The different gains can be changed by changing the resistor values. C5 filters out the DC, and C4 and R1 act as a low pass filter. Go to warplink.com for the values to use for the comonents. 5. Often times when dealing with amplifiers you will need a low pass filter. This can be done with a simple RC circuit. To find the frequency that you are filtering, use the formula F=1/(2*pi*R*C) 4. If building a robot that follows a line, it is important to have an Infrared sensor and detector. You can read about this in my line following robot post. 3. Often it is necessary to use a simple NPN transistor as an amplifier. This is useful as a preamp for a microphone, or even as a motor controller. 2. It is important to test your circuits before soldering anything together. Lots of times it is useful to have a powersupply that you can plug into the wall. Here is a circuit for building a 12v power supply. , this could be changed to a 5 volt power supply alsoThis is from a recent post of mine found at 12v power supply 1.

The Mcluhen argument that the development of technology is never a neutral is really important. But I don’t think it detracts from the case for the sheer practicality of the graffiti writer, although in this case it is from an activists point of view. In the post 9/11 climate when civil liberties are being increasingly stiffled it is important to have tools for civil disobediance which can a) compete with the society of the spectacle and b) deflect or prevent physical retaliation in what are essentially virtual power struggles.. The Critical Art Ensemble (http://www.critical-art.net/), who I beleive were involved in developing this robot write rather effectively about their intentions.
It would be useful when publishing the USB plug to make sure the (Plus in) +5 and +Data were legible. Now I know where they are but I am not the intended audience. Check for legibility in Diagrams of symbols. That’s why the ROW went to 4K7 instead of 4.7K.
I think theres a minor mistake in the article where you reference Vlight and Vnolight with the programming part. I think you may have switched up the two values.
“Since the vlight = 0.2, and vnolight(tape) = 3.8″
Other than that, it’s perfect!
Nice article, keep up the good work!

Thanks John Jeffers, I fixed the problem. I could read it fine on my laptop, I guess others could not. That is useful information. Some of the other schematics that I thought were hard to read I made clickable to bring up a larger image.
Thanks Andrew. I see that I mentioned it correctly when I introduced the topic. I fixed it. The funny thing is that I actually presented it to my class that way. Whoops. I can’t remember what we were thinking, but it seems like that is the way that they wanted us to present it. I don’t even know what the variables mean, but I am making this project, so I changed it to what makes sense. Thanks for pointing it out.

Some of these circuits are useful. However the obvious inconsistencies in the schematics show that they were ripped from other websites. My two cents: 1) Use schematics that are consistent in form and explain them. If you are trying to appeal to people who don’t know a lot about electronics random schematics without explanation of the symbols is very weak. 2) Provide follow up sources of books or websites to provide more detail 3) About half of these circuits are typically needed by the novice, they look more like the first 10 circuits that the author used.
Actually most of these schematics are either hand drawn by me, and were used in my line following robot, or were drawn by me using ExpressSCH. A few were from other websites, but they were not ripped off from them. The websites were given credit. I did not write this as an explanation of how to read circuits, but for people with a small amount of knowledge that want to know how to wire simple parts together. I have recently given a post on how to read circuit symbols. It can be found here http://www.diylive.net/index.php/2005/12/09/circuit-symbols-for-noobs/

Sweeeeet. Maybe I can get my garage door open with this.
Thanks for these, much appreciated. I wouldn’t say the schematics are inconsistent – I’d have thought most people with any basic knowledge of electronics are perfectly at home reading conventional symbols in a variety of versions. Although I remember once being castigated for using /\/\/\ instead of [__] type resistors in a very basic sketched diagram!
I liked your list of circuits. Don’t worry too much about previous carping criticism. However, do worry about my carping criticisms:
1. I think analog circuit diagrams are *much* easier to understand if all components are arranged so that the pin with highest DC voltage is at the top.
2. The bias setup in your mic amp (circuit 3) looks all wrong. I don’t know the dc gain of the 3904, but if it’s more than about 10 the collector is going to be pulled way too low. I think you were thinking “hmm, about 200 mV from the mic, about 2 V output — OK”. Also, you’re driving a low-impedance input from a high-impedance output. You need to do a full bias setup to get consistent output DC at the collector: ie, use an emitter resistot, bypassed with a cap if you need maximum gain (probably not but you never know for a mic circuit). Also, your users are probably going to try to drive random lengths of wire: instability! (If you don’t check with a scope, you may never even *know* it’s unstable — all you know is that the bias point seems to wander, it’s distorted, etc etc…)
3. Generally, your components seem old-fashioned. I was using designs like this 30 years ago. How about more integrated devices like serial/RS232 conversion (max232 — no longer high tech!), negative voltage regulators, usb interfaces, etc? The audio amp you show seems particularly fussy. I vaguely remember more integrated designs for little audio amps thirty years ago.
4. A general problem for tinkerers is that in a lot of cases they want to make the circuit work with a single, or maybe two, 1.5-V batteries. Ideas?
Danny, I like your advice. I would gladly look at some designs you have, esp. on the mic amp.
If you have a schematic in mind would you email it to me? lipscgr@gmail.com. I will post an ammendment to this article.
As far as your number three goes. I agree, these are old circuits, but are very simple. I would not say that since they are over thirty years old that an LED circuit is invalid. They are essential to understand in order to move on. I like your idea though, and may post a more “modern” IC list. I would add microcontrollers, and DTMF encoder/decoders, as well as the devices that you mentioned.
Thanks for taking the time to look over my stuff.
You would have to find the exact frequency that your garage door works on, and would have to find out what kind of output your garage door opener is giving. You would prob. have to add a microcontroller to the circuit to output the serial data that you would need, but you are correct in that it should work. Assuming your garage door is operated on FM, which is most likely is.
At Carnegie Mellon we had a contest like this, called “Mobot”. There were lines drawn along the sidewalk prior to the competition, and on competition-day the contestants were told which route to follow and gates to pass through, etc.

Why don’t you just hook a few photoresistors to a comparator? Look at Sandwich at http://www.robotroom.com.
Thanks for these. As a beginner trying to get into DIY circuits, this kind of advice is invaluable!
As a total newbie, another thing that I would find incredibly helpful is actual photos of a breadboard with these circuits built. I’m sure for y’all who’ve done these a million times, the schematic is enough, but for us newbies it really is kind of confusing; what wires to where? How do both those pins go to ground? Certainly there’s more than one way to wire up a circuit, but seeing an actual breadboard with all jumpers and components next to the schematic is incredibly helpful. Again, for non-newbies it’s probably a total waste of time, but for the beginner, electricity is just…weird. So seeing real examples is very helpful in making basic circuits. Thanks again!

You could easily do this. The frequencies are set for an FM radio though. If you wanted to use it for a sound system at like a church, you would have to build a receiver also, and find the correct frequency from the FCC. It would not be that hard, and could be done.

What about the awesome Zen Micro altoids tin case? It’s like they were made for eachother…

My wife got me the exact same thing for Christmas. I’m finding it a little difficult to get started so I am looking for some sample projects to build to get my feet wet. I’d like to see you post a project or two here.

I believe you’ll find that the maximum output current depends on the difference between input and output voltage. For linear regulators, Iin is about the same as Iout, but Vin is higher than Vout. Thus, the power dissipated by LM317 is Iin * (Vout-Vin). The result is in Watts.
The maximum operating temperature of LM317 is 125C, and we’ll make ambient temperature 50C. This means the temperature rise due to power dissipation may be up to 75 degrees.
The datasheet I have gives the “Thermal Resistance, Junction-to-Ambient (No Heat Sink)” as 50 degC/W for the TO-220 case. That means permissible heat dissipation is 1.5W. So if you’re dropping from a 24V input to a 5V output, you’re limited to about 80mA (1.5W / 19V = 79.95mA).
With an infinite heatsink, you can use the figure for “Thermal Resistance, Junction-To-Case” of 4 degC/W, or 18.75W. Now, if you’re dropping from a 24V input to a 5V output, you’re limited to around 1A (18.75W / 19V = 986.8mA).
Now, if you have a 9V input and need a 5V output, the drop is 4V instead of 19V. That changes things quite a bit. With no heatsink, you can get 1.5W / 4V = 375mA and with an infinite heatsink you can get over 4A (except I believe in this case there is additional current-limiting circuitry in the LM317 which will give you a lower current limit than this).
Another use I’ve made of the LM317 is a constant-current regulator to drive LEDs. Basically, compared to the above diagram, replace R1 with a current control resistor, and R2 with the “load” (one or more LEDs). The current is 1.2/R1, so a 60 ohm resistor gives 20mA current. As long as the input voltage is about 3V higher than the voltage drop across the LEDs, you’ll run them at exactly the right current. When the input voltage is lower, the output voltage will decrease until the LEDs eventually go out. For more about this circuit, see my blog entry about it: http://emergent.unpythonic.net/index.cgi/projects/01111254927

Hey John, Welcome to DIY Live. I REALLY enjoyed your article. I think you did a fantastic job with it. I really hope I did not offend you in my article. I see it is mistakingly a little harsh. I will reword it.
No offense taken. Several coworkers had the same suggestion when I was still breadboarding the clock. I just stayed with what I felt comfortable with.
I’m glad you enjoyed the article. As an aside, I probably never would have pursued building a binary clock if I could have just bought one. However, ThinkGeek wasn’t selling them yet, and while ElectronicsUSA.com and HobbyTron both sold “binary” clock kits that you can buy fully assembled, they are BCD clocks — not binary. The only place I found that offered fully assembled real binary clocks was ESP Technology (http://www.esptec.com/Clocks/RoundedEdge.html). These clocks looked nice, could be ordered with any color LEDs and orientation, and were priced quite reasonably. Unfortunately, they appear to no longer be in business, as they never responded to any of the email inquiries I sent. Thus, if I wanted a binary clock, I would have to design and build it myself. True story.

Thanks man. I really liked your site as well. I would love to write an Atari 2600 game. It was around during my younger times. So my question is, if I had that pc board and an EEPROM, could you program a ROM on the chip and play it on your Atari?
I would be doing more cool how-to projects if I wasn’t hammered this year. Sadly, I can’t even play with my PIC chip programmer
Thanks David, I will check it out.
I’ll second the recommendation for AtariAge. The documentation placed there was highly instrumental in getting to understand how the Atari VCS worked and getting my first programs to run. I also give kudos to p65 and to the guys behind Stella (particularly the new version which has very nice debugging capabilities, it’s really nice to single step through things and see what the machine is drawing with each instruction).
In case it wasn’t clear, the picture of my Enigma Machine that you have is actually running on a VCS. I scavenged an old SuperBreakout cartridge, disassembled it, pulled out the old PC board, plugged in the new one with my freshly programmed AT28C64 EEPROM, and that’s what you get! So yeah, with the stuff you listed, you can actually make real hardware. I even made a label ( http://brainwagon.org/images/atari.png is an early version, I’ll have to find the final version on my laptop sometime) and reassenbled it into a nice cartridge which sits alongside Pitfall II.
Good stuff.
Nice article, Bad spelling though, Wesler is Weller (a very long-term well-established name in soldering). Krunos is Kronus (a fairly new line with Radio Shack.) ( **EDIT-Thanks for catching those.. I fixed the mistakes. I wrote this article in a hurry-EDIT**) Note that many of the tools that the Shack carries are also carried at Sears, available as individual tools (or sets), and carry the Craftsman guarantee, break it and they replace it. This has held hobbyists and garage-jockeys in good tools for decades!
As for sponges, they are an absolute requirement, but cheap kitchen sponges made of any kind of plastic material are a danger: they’ll melt onto your iron! I get the best results with sponge intended for iron use, and the Plato CS-17 is a good buy at $15.53 (or so). It’s an 8.5″ x 17″ sheet. Cut it to fit your stand’s dish or to fit into an ashtray, cut a hole in the middle (to wipe globs of solder into, come on, we all do it sooner or later!) and you’re good to go. One sheet should last for a very long time, and it’s way smarter than paying 10-15 bucks for a 2″x3″ pre-shaped one! (My listing for it is via Newark in One (www.newarkinone.com) 98H2582)
Solder wick is a reasonable if pricier alternative for the soldersucker, and where the sucker may have difficulty getting a good grip on molten solder in some cases, the wick usually gets it all. You may have to add a bit more solder to ensure the wick can connect, though. Wick is available from a number of manufacturers and can be found at most of the major suppliers (newark, mouser, digi-key, jameco, etc.)
The cheaper radio-shack meters are a very good alternative to the more expensive ones. They all have limitations (even the Flukes, although they have very clear specs on the limits of their meters) and using a meter that you don’t understand the limits of is sometimes as accurate as using a pair of chopsticks. Note also that some cheap digital meters autorange and have no control to choose the range to use: the latest (yellow rubbery coated) RS meter has a control for choosing range or letting it autorange, and will also select AC/DC automatically, if you let it, but lets you choose that setting as well. This is good: a meter can’t decide what you’re trying to measure correctly all the time! But again, be sure that what you are reading is what you think you are measuring: if the meter is auto-reading DC and you wanted to know the AC component, it’s not your friend.
The solderman extra-hands thingie is a real luxury, far more than the oscilloscope. A good solder connection starts with a good mechanical connection, even in the hobby world. Otherwise, the solder connection will be constantly stressed, and it’s really not meant to be a robust physical join. It’s not that hard to bend contacts/wires to make a good physical connection that can be soldered. This makes a set of good hand tools (missing from your list) far more important than the hands-free jig. Minimum should be a set of wire cutters and a small long-nose pliers with cross-hatch on the jaws. These can be gotten at a Sears tool store for under 10 bucks each (far under, really). After this, and only upon real need, you can add long-nose pliers of other sizes with and without gripping jaws, flush-cut wirecutters, and/or vise-grips, but any of those are going to need a real reason to get to start with. Once they’ve been acquired, though, they’ll become a constant pleasure to have.
I’d categorize what you have here as
Necessary for effective DIY:
1) good soldering tool (temp-controlled iron with a stand and a sponge)
2) solder sucker or wick
3) tool organizer/box
4) good multi-function meter (with good leads!)
5) good strippers (although the far-less good multifunction strippers/crimpers/screw cutters are more common, they really fail early and often)
6) good hand tools (you list the multi-bit screwdriver)
7) oscilloscope if you can get it
and add to this,
under 3, wire cutters and small long-nose pliers, x-acto knife, crazy glue
The solderless breadboard is possibly one of the worst things a DIY’er can do to themselves, though: it wears out very quickly, it adds resistance and reactance in unpredictable, undesirable ways, you can’t clean the contacts, you can’t stick two wires in next to each other in the same contacts because the larger one prevents the contacts from closing on the smaller one (which generally flops around or becomes intermittant!).
Good soldering habits, good wick, good hand tools (the minimum listed above) and a little patience makes dead-bug/breadboarding far preferrable, lets a DIY’er get into much more sensitive and higher-frequency fun, and leaves the parts as usable afterwards as being pushed into a solderless breadboard and futzed with trying to get good contacts and make spurious effects go away!
Thanks for these great comments. Please leave feedback, and I will compile them into a DIY Live toolbox including suggestions from all of the readers. Harold is exactly right.

You are absolutely right. That is simply a binary form of what this is doing. Instead of thinking about the LED, you could use a binary number system, you would have 00 01 11 10 00, or if the other phase was leading, it would be 00 10 11 01 00. This would be important in microcontrollers. It gives you a way to create an algorithm to produce this simulated wave. Thanks wdk, I knew about this, but did not know the name of it.
Hey,
My mouse only had one sensor per wheel also, and has the three pins. For me, the center pin was high, and the outer two went to the two different sensors on the same component. It works the same way as the other one does.
About the sin cosin relationship. That is true. I saw this on my oscilloscope, but you would not have to create a sin wave to control it. A simple square wave will control it because the internal circuitry is only looking for a high volt or a low volt. It does a sin wave because as the wheel is turning, it is not instantly removing all light from it, but is slowly doing it. But if you connect two switches two the two inputs for the switch, and you press them in this gray code manner, then it moves the cursor.
Somewhere around here I have a mouse with 1 LED per wheel.
Even though the mouse has been non-functional for years, I figure the sensors are worth holding on to, since they are similar to the sensors used in an atomic force microscope. (http://en.wikipedia.org/wiki/Atomic_force_microscope)
I’ve always wondered how difficult it would be to build an AFM at home.
A quick google search shows it’s easy to find instructions for building a scanning tunelling microscope, but I want something that works with nonconductive samples.
It would not be a hard hack. You can search for a dvd player in a nintendo.

I would suspect that the quality is not the greatest. If you could somehow shield the wires, it would not be that bad at all.
Hmmm I doubt that the quality of the signal will remain the same after it passes through the CAT5 cable. We have alot of potential for loss here.. the original vga cable, 2 converters, and a variable lenght of cat5 cable.
Would have to try to know.. Anyone ever did it?
If you Guys are interested in making your own CAT5 cable, I wrote a tutorial right here: http://geeksaresexy.blogspot.com/2006/01/save-money-how-to-make-your-own.html
Sorry to be the one to point this out, but a long (25 foot) VGA cable can be purchased for about the same $ as a comparable length ethernet cable (for example, see http://www.cablesforless.com/index.asp?PageAction=VIEWPROD&ProdID=1661 , this one sells for about $12.)
“But shielding should help improve signal integrity over longer runs.”
Only in environment where there is some RF/electrical noise.. If you do this at home, and you do not run your wire beside a power Cable, you wont see the difference with UTP, STP or ScTP. The maximum lenght is the same.

I decided to find a few links for everyone to go to that will help them understand circuits, and circuit design. The first site that I go to a lot is allaboutcircuits.com. This is an invaluable resource. This site does a very good job of walking you through all of the steps from the beginning of understanding basic voltage theory to using advanced ICs. The next site that I found helpful is electronics-tutorials.com. This is a good basics tutorial that defines a lot of the terms used in electronics, such as resistance, and capacitance, and voltage. He starts out with electron theory, and moves from there. I highly suggest anyone starting out in electronics to read this. It is very important to understand these terms. It is also important to know basic circuit analysis. I have written a very basic post on this. If you know V=IR, then you can do most simple things. When picking a resistor for an LED, it is important to know your voltage source, and the voltage and current requirements for the LED. You then re-arrange this equation for R, which is R=V/I, (Resistance=voltage/current). This is the value of resistor that you would use. It is also important to know how to read a schematic. All of those symbols can be overwhelming. There is help though. http://www.kpsec.freeuk.com/symbol.htm is a site that gives a good list of circuit symbols for anyone looking for help. It doesn’t have a resistor symbol, which I found strange, so here is another site with more common components. Anyway, I hope this is something simple to get most people started. One of the best resources in DIY electronics is the chance to ask others questions. It is much easier to learn from others than by yourself.

Von Skippy, please be understanding. I will continue to give electronics updates. Unfortunately my focus right now is on studying pharmacology, and pathology, and Step 1 of my boards. Be patient, and I will be through this awful semester soon, and will be able to dedicate more time to electronics hacks.

I do much better in EE classes, but I am not in medical school to be a student. I want to be a doctor, and engineering is just a passion and hobby of mine.
Thanks Alan, It is good to hear from you. Honestly, I did not have time, and should not have been posting everyday.
. I am prob. just going to post once a week for a while. My friend is not going to write for me, so I will just have to make it through.
I do look at First Aid, but they changed it to systems based this year, and it kinda stinks.
Actually the problem I am having is that they took all neuro stuff from phys, and path, and combined it with neuro anatomy into a systems based course. I am taking it right now with path, and with pharm. It is killing all of us. My school is so backwards.
Really. I have never seen one that way. That is interesting. Well, I guess it is not a fool proof plan, but it is a “general” guideline. You could always just put a small voltage on it, and flip it around until it turns on. Honestly, that is what I do
Now, I have a bigger question. If you find a bucket full of LEDs, I do not know how to figure out the voltage rating for them. How do you decide the resistor value for an LED when you don’t know the LED values? There has to be a way, if anyone knows then leave a comment.
Oh and Brandon, all you have to do for the IR LED, is you could build a detector circuit that was permanently mounted, with a transistor, and another regular LED. You could shine your infrared LED at your new circuit, and if it is on, your circuit would turn on the visible LED. It would be kind of a checker. That way you would know if you accidently fried your IR LED. (Which I have done several times sadly)

[...] It has been a while since I have talked about any projects from cornell university. I was just searching through, and found something that I thought was very interesting. Just yesterday I wrote about Brandon’s powerglove mouse from zerosign.net. As I was searching, I found an article named Air Mouse. This struck my interest, and I found the picture above. These guys took a girl’s prom glove, and attached an accelerometer to one finger. They also attached 4 buttons to the middle finger. They use an Atmel Mega 32 to interprate the signals from the sensors on the glove and to create the RS232 serial output for the computer. This glove has left and right click mouse buttons. It also has a on/off button so that the person can type. The fourth button is a scroll button. When this is pressed, the y position of the glove is turned into a scroll up and down. This glove has a neat way of movement that causes the cursor to move. If you roll your hand to the left, the cursor will go left, and if you roll it right, the cursor will follow. If you pitch your hand up or down, meaning bend it at the wrist, the cursor will go up and down. By doing it this way, it requires very little movement of the hand to cause a change in position. The only drawbacks are that there are wires attached to the glove, which seems like it would get in the way. Also, the buttons seem annoying. I like the variable resistor idea from the powerglove. But if you could somehow combine the two, then it would be something special. If you had a glove that was really light weight, and was wireless, and was very easy to move, it might actually be useful. I don’t know if i would like it or not. I think it may get hot. Go read about their project, it is very interesting. [Link] [...]

[...] I have already talked about a DTMF decoder, and some of the many uses for one. I ran across a short article, that sparked my interest in these chips. What does DTMF mean? It means “dual tone multi frequency”. Who would have thought that a dial tone on a phone was actually two different frequencies that were modulated together? Why would they do this? Well the reason is that this gives a powerful way to send data, without the chance of interference. If there are only several different expressions that need to be sent, then this is a nice way to do it. There are only 8 tones that are modulated. There is a high tone, and a low tone in each set of modulations. This gives a total of 16 possible modulated tones, of course a telephone keypad only uses 12. Anyway, Raphnet.net found an old answering machine and pulled out the CD22204 chip. This will demodulate the codes. He connected it to a microcontroller and connected that to a serial port on a computer. He wanted to keep track of what phone numbers he was dialing. [Link] This is only one of many possible uses for this chip. It could be used for building an IR remote. You could build a transmitter that used an IR LED, and then transmit signals to an IR sensor. You simply decode what you are picking up, and connect the chip to whatever you want to control. Another project that I found was a DTMF decoder that was connected to a microphone. This microphone had a pre-amplifier, which connected the signal to a SSI-202 DTMF decoder chip. He then connected this to a Basic Stamp which sent out serial data to a LCD screen. He basically displayed what numbers were being called by what it heard. [Link] Anyway, I have already discussed some uses with this chip in a previous post. I linked to an extensive overview on how this chip works. If you are interested in reading more about this, you can find my post here. [...]

Hi Really liked the idea of this project,

would anyone know how to integrate this H-Bridge into this
project, as it would seem to have 4 input pins instead of the
2 phase pins used on the H-Bridge in this project, or could
someone suggest a replacement H-Bridge that would do a
similar job, cheers for any help.

I agree, I like your mnemonic
Actually, it is easiest to remember these from the colors of the rainbow.
The absence of light is black, and they progressively get brighter.
so you have Black, then Brown, and then if you remember ROY G. BIV, from third grade, these are the colors of the spectrum. Then above that you have gray, and then white, which is the brightest. So you have
Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White.
Note, that indigo is not a color for resistors. Who really knows what color indigo is anyway?
.. There is not enough contrast between that and blue, so it is left out.

That was the original mnemonic, but I removed it because it is very crude.

[...] My father was an electrical engineer. This is the kind of stuff he knew. I remember once learning this, but it was probably 20 years ago, so I’ve forgotten how. Guess I should use the information to bone up on my knowledge I don’t actually use for anything. (via MAKE blog) Resistors are coded with colored bands in its shell, usually four colors but sometimes you can find five. Each color represent numbers which you can decode to get the exact value. The first three colors are the resistance values and the fourth color represents the tolerance. [...]
Then the question is, what current is flowing through the body from a cap at 300 volts? I guess it depends on the resistance of the body. If the current passes through the heart though, it can cause it to go into atrial fibrillation, or worse ventricular fibrillation, at which time you are toast. Actually 100-300 mA across the heart can cause ventricular fibrillation. So it doesn’t really matter that the voltage does not kill you, because there is enough charge built up in some capacitors to deliver a high current. Regardless, caps can be very dangerous.
I am glad that mine did not “melt” to me.

Actually, building your own plane can be surprisingly safe. These planes don’t fly very fast, and as long as you follow the directions exactly, and use aircraft quality parts, they are usually safe.
As far as a pilot’s license, you don’t have to have one. You can learn to fly an ultralight through someone else, and are not required to have a license. I don’t know if you can carry passengers though.

There is some restricted airspace. If you don’t have a full pilot’s license I don’t think you can enter controlled space. It is not so much the plane though. If you don’t have some instruments in the plane there may be some spaces you can’t enter also.
These planes aren’t super fast. They go like 65 mph. You need to be able to go at least 100-115 to really cut the time down significantly. Of course it is direct flight, and non-stop, so it would probably cut the time in half. But it would take that much time to get the plane going. It is much better to fly on a trip that takes around 2-4 hrs. That is when it starts to save time.

Hey superpositioned, I am excited about your new projects. Let me know about them.
[...] I have been looking for a while for a POV (persistance of vision, or as I prefer to call it a spinning LED) that uses an electric motor to spin the circuit. You can see my previous “Spinning LED” project that I made in undergrad here. Here is a cool project that uses an electric fan as the motor, and the spinning marquee displays a clock. This is also a good PIC project. It uses a PIC16F84 microcontroller. It uses an opto sensor as the reset. Check out this site here. Red digits on this photo appear to float in the air in front of the clock. This illusion is based on inertia of a human eye. If LED-formed digits will periodically and frequently enough flash, they will appear solid and steady. And since the matrix of digits is formed by a mechanically scanned single line of LEDs, and the fast rotating clock body is not visible, it leaves digits “suspended” in the air. The first clock using this concept was built (and PIC microcontroller code written) by Bob Blick, please visit his page for yet more photos of his original clock and clocks built by other people.

Hey thanks,
3rd year of medschool is much better than the first two years. I once heard a phrase which I completely agree with. “The worst day of 3rd and 4th year is much better than the best day of 1st and 2nd year”. Of course I am busier at times, but it is nice to see things that actually seem pertinent to my education. I was able to deliver my first baby a week or so ago, and it was an amazing experience.

[...] So if you have decided that it actually is worth your time to make some cables, how would you go about doing it? You need a soldering iron, the only “real” investment you actually need to make. If you think that this is something you would want to persue long term (and most studio owners do), be it making cables, or experimenting in the DIY world of audio, then I would suggest investing in something a little more sturdy. Something slightly more expensive and industrial will last you a long time and get you though bigger projects. Not only that, but about ten 10′ cables will pay for a nice Hakko or Weller station. However, an iron capable of producing temperatures of around 700° (20 watts or so) should suffice for any cable that you want to make. Solder is a cheap but crucial component in this project, so I would suggest some 63/37 tin/lead mix solder, availible anywhere solder is sold, and a pair of wire strippers. Next you need to learn to solder (or learn as you go), which is nowhere near as hard as you might think. There’s a great general guide on how to solder over at DIY Live which will get you going in the right direction. While that seems to focus a little more on circuitboard soldering, the techniques are still solid and relevant to this project. There is also a compilation of soldering resources at MAKE Blog. Basically soldering comes down to melting soft metal onto the two places you want to connect. Pretty simple, huh? It is. [...]

Since this post is the #2 hit on google for the phrase “iPod won’t turn off” I thought I would point people to a page where I posted about the solution to this problem.
http://ipod.wikia.com/wiki/My_iPod_Won%27t_Turn_Off
Basically, to turn an ipod off, you normally press and hold play for a couple of seconds. But sometimes this does not work. The first fix is to hold the center and menu buttons down for 10 seconds, which “resets” the iPod (basically a reboot).
If the problem persists, the solution seems to be a complete restore, which wipes all the songs and music so you have to reload everything onto it.
the project is fascinating.

I’ve done all these things, reset, reboot, and update, but when I hold the play/pause button it turns
off, but when I go to hit the hold button it turns back on with a “battery sign” and it won’t turn
off. I thought the 5 gen ipod had a feature where it automatically turned off. What do I do?

[...] Shit on me, Im in love. I have long admired the pioneering work of Rancilio Silvia owners in modding their espresso machines. Here, I present my Silvia given a PIC 16F876 microcontroller brain, a 20 character VFD display, nintendo controller, three zero-crossing solid state relays, IC thermometer, laser cut acrylic top, cold cathode ground effects and shot light. This project has stretched out for quite some time, and will likely continue on as I pick away at it some more. But for now, the bulk of the first wave of coolness is complete. PID A microchip PIC16F876 gets temperature readings from a boiler-top mounted National LM34 Temperature Sensor. These temperature readings are processed using the PID control loop which I learned about in detail from the excellent article PID with out a PhD. A thrift store modder’s favorite NES controller can set the PID gains, espresso and steam setpoints, temperature calibration values, and heater control PWM period. I wrote the NES code by reading a fantastic spec available from the iGamePlay project. The NES gamepad’s popularity is well deserved as is a tough little controller with enough buttons to be useful, yet still very simple. For example, the select button switches between the main mode and setup mode, and the arrow buttons allow you to choose and alter variable values. It works out pretty cleanly. The main display currently shows a) the current temperature, b) the heater power setting (0 – 100 percent, which translates to a PWM heat amount), c) a timer showing how long the machine has been heating up, and d) a timer that alternates between a shot timer, and a timer showing how long the machine has been temperature stable and ready (remaining within 0.5 degrees of the set point). One of the most interesting challenges so far has actually been tuning the PID loop. Currently though, after it settles, the machine appears to be indefinitely stable (I’ve seen it stable for over 2 hours before shutting off the machine) to about 0.1 degrees of the set point temperature. Interestingly, stability improved substantially after I finally closed the machine back up (after easily a year of being in terminal state of "operational dissassembly") and insulated the boiler from room drafts etc. Shot Timer One of the big motivations to go the distance and give the PIC total machine control was to enable a shot timer. When the top switch is thrown, it starts counting the seconds. It was basically a lot of work to make the machine act like it always does, but just so the PIC knows about it. The front panel switches are all "virtual" just pulling pins on the microcontroller which in turn throws the relays. One cool side effect of this is that starting a shot no longer makes a click sound on my stereo speakers. I think this is because the zero-crossing relays remove the spark-gap that occurs with a normal 120 switch (that’s just a guess, but something changed because the grinder switch still sends out an electric ‘pop’ . . . for now). Remote Control Once I had the PIC sitting between the switches and the relays, and I had a NES controller setup to change PID values, my inner (or is that outer?) nerd forced me to add a useless "remote control" feature that replicates the front panel switches with the A, B, and start buttons on the gamepad. Eventually, I would like to put a solenoid on the steam wand valve so that I can call for water and steam completely with buttons and switches, and get rid of the squeeky knob (btw, does anyone know how to lubricate the steam valve with something more edible than WD-40?). Bling A combination 5v/12v power supply left the door open for some code cathode lights to sit on the 12v rail. While there is some utility in adding light under the brew head, this is mostly just silliness– especially my "ground effects." A laser cut clear acrylic top allows for the VFD display to be viewable without undermining the sleek boxy shape of the Silvia. While there are still quite a few wires swimming around under the top, the overall number has been reduced, and it makes for a fairly clean appearance from above. I removed both top-mounted thermostats, and the switches have only 2 wires each instead of 4 going to each switch. Sadly, the little switch lights don’t work. Though perhaps its possible to get them back? __________________ Quote: [...]

yay!! i had such a hard time turning off my iPod. rebooted it and everythings good. =]
thanks for the help…i had an issue where the ipod was repeatedly trying to start, spinning up and then immediately shutting down. it happened just after i downloaded and installed an ipod update through itunes. the device wouldn’t mount and the process kept repeating with a noise that sounded like it was misfiring. i fixed the problem by putting the device into disk mode (flip the hold on, then off and then pres play and select simultaneously). that enabled itunes to finally see the device. i then hit restore (which restores the ipod to factory defaults) and we’re back in business. cheers.

Ok, how did you get comments to work with feedburner? Do I need to make any chages to wp-feed.php file or just change the link in feedburner?
Heather, the video iPods are hard disk based. That whirring noise is the disk spinning up to start accessing the system. There’s nothing wrong with your system, it’s normal. Don’t bang the iPod while it’s doing that or you can possibly damage the disk. That’s the only drawback to the video iPods, but I love mine. I’ve got over 50 days of audio and several movies on mine (60 gb).

[...] Here is a fantastic project that I have found. It is a miniature ESC to use with one of those small RC cars such as a microsizer, or Bit Char, or ZipZap. An ESC is an Electronic Speed Control. It is basically a Motor Controller. I posted previously on using the transmitter and receiver for these cars to build a small airplane. The problem with the receiver is that it won’t support enough current to run larger motors, and it also only has power on or off. This ESC will allow you to change the speed of your motor. It also has a feature that will shut the motor off if there has not been any buttons pressed in the last few seconds. This will save the plane from flying away if it gets out of range. He uses an Atmel AVR Microcontroller, and a Mosfet transistor as the motor controller. Not bad for something smaller than a postage stamp. The BitESC is a small electronic speed controller for those little RC cars like the MicroSizer / BitChar-G. It can be used in a small RC plane to have some control over the speed of the motor. The speed of the motor ramps up or down, depending on which of the buttons on the transmitter you press. If no button is pressed, the ESC will ramp the throttle down to a stop after a few seconds. This safety net comes in handy when the plane flies out of transmitter reach. [...]
That’s pretty neat. The curve in that screen shot brings back less-than-fond memories of 10-hour lab reports though…

I got my plans 2 years ago and got the fuselage done in no time but I had to stop working on it
[I cut half my hand almost all the way off at work]. Now I’m working on it again and would like to
get my S/N, but my form was sent back to me [no such address]. Are these people still around?
Ivan, if you read this I’m from northern Illinois and used to live in neenah wis. Contact me if you
have any questions. bogie.57@sbcglobal.net .

I Just apparently Purchased the plans off the Aplane Site but I wish I had looked here first. Does this mean they aren’t going to be coming? I was REALLY looking forward to staring this plane soon, as soon as I got my plans to be exact. Anyone have any details they could leave me? Thanks in advance. Feel free to email me with any info you have Staticbox(at)Hotmail.com
hay what is up everyone does anyone know anything about the affordaplane
To all who ordered the affordaplane and got riped off go to this site and you are able to down load it http://www.ultraligero.net/sitios/planosl/affordaplane/aff I think I got riped off too anyone know where a person can put in a complant for someone like this let me know11 if you go to the search engine google and put in affordaplane scroll down and you will find this web page i think it is on the 2nd or 3rd page
http://www.ultraligero.net/sitios/planos/affordaplane/aff
Says the page is Not Found. Anyother places I could get it? Wouldnt that be some kind of law case? everyone pays into getting these plans without getting them just wasted their money. I want to know where I can get the plans And or My money back. This kinda sucks.
Great circuits more sites like this one make electronics so much more fun thanks. 555’s are great, op amps rock the hardest! again thanks.
Thanks for the reboot solution (no, you don’t lose anything). Mine was driving me crazy. You guys are awesome.
thanks! i really thought i was too old to figure out any of this tech stuff till i read your description.

I am currently building a line-follower robot with an object sesnor.I am having trouble designing a
motor circuit for it and was wondering if you could give me help/information. Thank you.
OK SO MY ROOMATE PLUGGED HIS 30GB IPOD INTO THE SAMSUNG WISELINK ON THE SIDE OF THE TV. THE IPOD SCREEN READ DO OT DISCONNECT. THE TV READ UNABLE TO READ DEVICE OR SOMETHING LIKE THAT. WELL I DECIDED TO DISCONNECT BECAUSE NEITHER DEVICE WAS DOING ANYTHING. THE IPOD WOULD NOT TURN ON OR DO ANYTHING AS IF THE BATTERY WAS DEAD. SO AFTER FAILING TO GET THE IPOD TO REBOOT WITH THE MENU AND PLAY PAUSE BUTTONS I OPENED UP THE CASE. THEN I DISCONNECTED THE BATTERY AND WAITED FOR A MINUTE AND PUT THIS THING BACK TOGETHER. NOW I SLIDE THE HOLD BUTTON ON AND OFF HOLD THE MENU AND PLAY PAUSE BUTTONS UNTIL THE LITTLE APPLE POPS UP. ONCE THIS HAPPENS THE SCREENS FLASHES A FEW TIMES WITH THE APPLE AND THEN IT LOOKS LIKE THE CONTRAST IS ALL JACKED UP. BUT WHEN TRYING TO REBOOT THE IPOD THE SCREEN LOOKS BLACK WITH THE APPLE IN THE MIDDLE AS IF NOTHING WAS WRONG.
WHAT CAN I DO
SOMEBODY PLEASE HELP SO I CAN GET THIS RETURD OFF MY BACK
I’m sure glad I saw this site before I gave my money away for nothing. Thanks for the warnings.
When you disconnected it it shorted the system and its basically fried dude, sorry to say it. but it said do not disconnect, always follow instructions like that, they are usually crucial

WELD IT TOGETHER.JD.
sounds like you have a lot going on right now, which are pretty cool. new hobby, new kid (M4 is decent timing for a kid, cuz your intern year will be rough and it’s usually either before or after starting residency), new rotation, new decision on what to do besides just “being a doctor”. I am on my anesthesia/pharm review block and intubation is a lot more work than I expected! I need to find some time for projects, but my free time has been spent fixing my car, oh yea and waiting for the match! RC flying is something I definitely want to get into–been playing MS flight sim 2004.
found another page on this subject. Go to http://www.ripoffreport.com/reports/ripoff21566.
Hey you and thanks for a very nice site
I just wanted to say that I’m happy on your way with the kid.
And that I also thinks planes are very cool
and that the post about your tiny RC plane build out of a micro car was extremely good, I enjoyed it a lot and have self started to buy parts home to a little robot build whit motors from micro cars
heya ppls!!
Hey guys, thanks for the replies. Joker333, I got to put an LMA in a pt the other day. I have been hanging out with the anesthesia guys while on surgery. I hope to do some intubations myself. RC flying is great. I actually just recently built my own plane out of styrofoam insulation. It flew a lot better than I thought it was going to. Good luck on match, it is not that far away. What are you going into?
B4Me, I am glad you are getting into building a robot. That tiny receiver is pretty cool, and you can do several things with them. I have a car that I want to break down, but I just don’t have the time to. I am excited about my kid. I will find out on Wed. what the sex is (hopefully that is:) )
I actually installed “Spam Karma2″, it does a pretty good job of moderating the comments for me. It makes some mistakes, but it is much better than before.
If there is an interest in discussing this plane You can join my forums, and discuss the Affordaplane, along with updates of building it. Someone would have to start a new thread.
LMA’s are so much easier than the blades to use, at least on the kid I’ve tried. I’m always afraid of popping out their teeth. I’m vying for med-peds. there’s actually a pretty close link to anesthesia and flying. the flight sims with the cabin mock-up’s were the inspiration for the anesthesia dummies (same ones that most medicine people use as well) we use. I think they were developed at South Florida. most med schools have them, the $250K machines that you can pretty much do anything you could to a real person eg dilating pupils, can take any IVFs and drips, real pulses, larnygospasm, etc, etc.

Your example of an AC motor/generator has a commutator (slipping contacts called brushes). A better example would be an AC induction motor that has no commutator.
hi..it’s really fantastic project from you..I surely like it and really interested to know better

You definitaly want to replace the 2n2222 by a real RF transistor.
I tried one of those circuits and, it was sending signals over a 10 meters range with a boosted
power supply. 9 volts ?
Good Work !
And great idea of Microphone in the end. You rock !
I dont understand the comments on here. so many people hating on you.
For one a schematic for a simple lowpass filter called ripped off??? who cares? its not like he copied some SSL schematics and called it his console mixing board. But anyways i agree “even if they are 30 years old” they are key circuits to understanding the greater picture. Thanks for sharing. and i respect you ability to maintain your professional reply’s dealing with some of earth idiots. peace
does it reck your ipod to leave it paused overnight?

respected sir,
with due respect first let me introduce myself iam kamal,doing engineering in robotics
and iam very much inspired with ur prestigious work i myself want to build some of ur robots like this one so if u can send me complete details of this one to my id i will be highly grateful,

I know of a product that will safely increase gas mileage 15-25%
that has been tested by everyone from German automobile engineers
to NASA. However, it costs a little over $5 a tank to use, which
maybe a wash anyways, depending on your car. $5 isn’t that much
to protect our environment. There is tons of research to find on

I tried everything to turn mine off. It was very frustrating! After being on all day, the low battery indicator came on and I decided to recharge it by putting it back in the SoundDock system (an external sound and recharging unit). It played until I hit the off button on the SoundDock remote control. Maybe that’s where things got messed up.
I purchased my plans approximately 2 years ago and had absolutely no problem in recieving them. However,I am just now getting started on this project. I would appreciate any input from other Affordaplane builders. If there is anyone with a completed plane in Texas or Oklahoma please email me. I would be interested in seeing a finished plane. Anyone with info please email me at: kckcenterprise@sbcglobal.net

OMFG gettin all worked up about someone reposting some old info on his website he copied
from a different site.
Get real and get a life there is more to life then to fidget about someone copying some info.
why dont you go to the big news websites and bug them for copying eachother’s source
im sure they really apreciate your 2 bits of whining .
Keep up the good work. Pay no mind to those who like to criticize about
origins of the diagrams, nobody has a patent on these and wikopedia also
borrows them. If anyone can be used as an example of borrowing certainly
they are the best at it. Just make sure you do not have any inaccuracies.
Correct them. Your site is a great service to those who want to experiment,
hobby, or just luv this stuff. Thanks.

I have just started building my APlane. Had no problem getting the plans as I bought the e-version. I have had a couple of questions about things in the Bill of Materials but have been unable to contact Edwards. The phone number listed in one of the comments above went to an answering machine with a female voice saying they weren’t able to answer the phone. I think I saw somewhere that he was no longer in Riverview. I hope to get mine in the air soon so I can use it down at the border as part of the Minuteman Civil Defense Corp surveillance down there. Anyone wishing to correspond reference building the APlane feel free. The more we share ideas the better.

OH… Man “Springiness” that’s awesome you had me laughing for a while. good stuff. I’ll keep that

Just a note to everyone if your thinking of buying the plans affordaplane
be carefull I got riped off I am now going to purchase the plans
Legal Eagle it can be welded together and is the same size as the affordaplane
with a better designed wing and guess what you can actualy see the machine fly
so do your self a favor and go this route because you could get burned as I did here

Jimi.. I think you are are the looser
Thanks.
If it won’t switch off it’s often because it’s in disk mode. Just push play and select together and then it will turn off when you hold down play.
Well, the advice is sound if it’s a software problem in the ipod, but it can also be a hardware problem. I had an ipod nano and no matter whether I reset it or not, it wouldn’t turn off. I started putting it on the sleep timer to make it shut down.. I think it’s a mechanical defect in the clicker wheel sinceI hear a click when I press every area of the wheel except the one that’s supposed to turn the thing off.

Another way to add digital outputs to a PIC is to use the PWM command (pulse width modulation). this, used with a cap and resister, uses a pulsating digital out to output a varying voltage. this then can be plugged into an ADC to give you as many digital outputs as you have resolution for.

I have been working in mortgage industry for about 5 years and we found a solution that does this. We use it for wireless bar code reading and GPS tracking. The best part is we can customize the forms on-the-fly which saves us a lot of time over a customized solution. The company that makes the product is Westlake out of LA I think. There website is http://www.westlakesoftware.com. Their product is call AirMobility.net. They made a custom Extranet for us for our company to use but their main product site is http://www.airmobility.net. We found this service set up to make it pretty easy for us to migrate the information to our back office system. We use the technology and route it to 40 different servers nationally; has worked flawlessly for about three years. Customer service is really nice, just contact them, im sure they can help you out.

Does the capacitor have to be 470 pf?
No, you don’t have to use exactly this cap. Anything from 470 pF to 10 nF will work, it may soften the video, but it will work.

[...] Here is a design for a circuit that will take pictures of lightning. It is basically a light sensor that is amplified and passed through a high pass filter to record fast changes in light, and then attached to a relay that trips the camera. This seems very similar to my design of the external disposable camera flash. My design uses a microcontroller to do all of the hard work for you. I much prefer to use programming anytime I can to save work on using hardware. In a nutshell, the photo darlington converts light pulses into electrical pulses, the first LM324 section amplifies the electrical pulses, the second LM324 section is a high pass filter that only passes quick changes (lightning). The third LM324 stage is a comparator that allows only large pulses to pass through, and the 4047 one-shot stretches out the length of the pulses so that they are long enough to drive the relay and trigger the camera. The 2N3904 drives the reed relay, which in turn triggers the camera’s electronic shutter switch. The VN10KM prevents the circuit from triggering the camera when it is first turned on. The LM324 GND Ref circuit divides the 9V power into two for a 4.5V ground reference. The other op-amp circuits use this reference value. [...]
[...] I have been looking at mods and hacks for a while now, and I always save them when I see something cool. I have done several DIY projects using a disposable camera, and so they have always peaked my interest. I decided to take all of the mods that I have seen over the last few years and make a top ten list of what I think are the coolest mods for a disposable camera. These hacks are in no particular order. 10. Macro photography with Disposable Camera This is something I did a while back while working on a project of mine. I actually stumbled upon it. It is nothing special, and the pictures are not even that great, but the point was to me at least was that it worked, and it was cool. You just take the lens off of a disposable camera and place it in front of your lens, and then move close to an object until it is in focus and take a picture. 9. Grafitti Light This is a project that I believe I found from Makezine a while back, and I just saved it. It inspired my flash slave. This project makes an automatic timer circuit that charges the flash, and then flashes it repetitively. This guy made a stencil that says a message, “no war” in this case, and places the flash behind the stencil shining through the lens. I am convinced that I can use this concept to make a slide projector, and have worked on it, but I need a bright light source and finally gave up. 8. RFID Zapper This project was big a few years back, but I never paid much attention to it. I don’t have any reason to zap RFID tags, and I actually could not tell even if I did zap one. This project is cool though, and basically sends out a large electromagnetic wave to zap them. Don’t get your ipod too close. 7. Disposable Camera Flash Slave This project is one of my own creations. I really like photography, and know the values of an external flash slave. It can allow the photographer to do a lot of neat things with the lighting. To buy one is expensive, so I decided to make my own. It has a photocell detecting light, and has a microcontroller that charges the flash for you, and then gets everything ready. When the camera sees an external flash, it fires the disposable camera adding light during the exposure. You can even take a picture of the flash going off. [...]

Just a tip, you need to reverse the imaged on your stero photograph test. In the currect configuration, the 3d is inverted, so things that are far away apear closer and vice versa… It makes for a brain-hurting image when you cross your eyes to view it.
Switch the two images around, cross your eyes, and you should see it. I reversed the two positions myself in photoshop and it looks fantastic!

[...] Lightning activated camera shutter trigger – [via] Link. [...]
If you use the technique for magic eye posters on the stereoscopic image, then yes they need reversing, BUT I could never do those posters but found going cross eyed gave me an inverted 3d image. Same technique works here.
Can any of you make this picture look 3d? Is there some sort of program that will combine these pictures and make a 3d image using 3d glasses?
Actually there’s two techniques for viewing stereo images. One is to look through the image until the pictures merge, and the other is to cross your eyes until they merge. I have a book called “Stereograms” with some images set up one way, some the other. Once I got finished leafing through the book, I got the techniques down, and now I can see both types without any trouble.
Greg, you can use Photoshop or a similar program and it’s actually really simple, you simply copy the red channel of one image and paste it into the red channel of the other image. Check it out with 3D glasses. If the perspective is inverted, undo and try it the other way around.
The railgun has my vote!
I tried the red channel thing, and got it to work. I just don’t have any 3d glasses, so it was kind of worthless.
I don’t understand what you want Ma7amed.
It also helps if both of the images in a 3D shot like this are the same size. In this case, the right images is quite a bit wider than the left.
Yeh, i can cross my eyes to make it look 3D.
It adds SO much to a photo, I was looking at the back-yard photo for ages, once you’ve “locked in” your eyes, its easy to look around the whole photo.
Bloody amazing, I only wish I could get hold of disposable digital cameras in the UK. Anyone know of a place?

Well, I guess I will have to keep looking then. I have a correction, the rail gun is actually a coil gun. I call it a rail gun because it is a similar idea, and I have seen a large rail gun at Auburn University. Oh well, it is the same to me.
thanks for the info…really helpful!!!
what a great site
I saw a mod where you can take your sony video camera, put a specific filter on it over the night shot mode , use it during the day on that mode and it will shoot through peoples clothing
Did anyone started building frome those free plans? are they the same as original.. besouse after some serios reading and looking at the plans some measures are missing or deleted and I fear some of them are wrong … thank you for answers!
Thank u so much dustin my ipod wouldnt turn off so i rebooted it like u told us a way too and it turned off!!!!!!!!!thank u so much

Hi,
I read this paragraph and looked at the picture. Nothing else was there. No measurements nor
any actual and complete plans were found. When I would click on to “this article” which was
high-lighted in blue along with the word “LINK”, nothing substantial would happen. I’d get some
screen notice about how the website or page of a website was unavailable or non-existstant. It is
like a recording from the phone company about how I got the wrong number and no further info is
available.
I’ll try some more with hopes that I’ll stumble on to the plans for assembling a directional
cell phone antenna.
If you also have any plans on building your own normal omni-directional cell phone antenna, then
send me the website address. I’d hope to construct it with a magnet mount base to use on tops of vehicles.
Hi,
I found the website. It is exactly, ” http://www.geocities.com/robert_maria/ “. Post that on your

[...] Well, we have probably all seen the 9v altoid Ipod charger. An example is from the one that Aaron Dunlap has produced. I have to hand it to him. He has done a good job of promoting his idea. We all know though, I hope, that using a 9v battery, and a 7805 voltage regulator to produce a 5v source is a terrible way to charge an iPod. Our friend over at ladyada.net has produced a step up power supply using 2 AA batteries stuffed inside an altoid gum canister. A step-up power supply is basically a DC-DC converter. It allows you to take a small DC voltage and up it to a higher DC voltage. Ladyada does a great job of explaining all of this, and shows how she chose the parts, and designed it. You can buy the kit from her here. This is very similar to the DIY LED flashlight that I wrote about a while back. [...]

Regarding the reference voltage, the data sheet also tells the purpose of that one
Well, at least they have a story. It’s not unlikely that they just had an unused pin so they wired the most sensible internal signal to it.
Their story is that in case you have some external component like an ADC which needs some good reference voltage one can take it from pin 3. It’s low current, but approx. +-2% voltage precision. Which is not to bad, and in fact better than what one gets for 5V output (+-4%).
The block diagram in the data sheet tells how the same reference voltage is used internally in the chip.
(a) To detect low battery input. The reference voltage is 1.25 V. And surprise, surprise, low battery input is specified as being lower than 1.25 V
(b) To compare against the chip’s output voltage and drive the regulator to keep the output voltage stable.

I highly recommend Embedded Controller Hardware Design by Ken Arnold for this purpose – it goes step-by-step (with examples) through a lot of the heavy material contained in datasheets such as timing diagrams, loading, and noise margin analysis. Of the ~20 electronics books I own, I feel that this book was the greatest help in *truely* understanding datasheets, and showing me exactly why you shouldn’t gloss over the “strange” parts – they are there for a very good reason!
It’s very beautifully.

“I should have made it where the camera will have to flash twice to flip the switch, so I don’t know for sure if the relay will work in a standard camera without a pre-flash. It may take so long to trip the relay (RLY2) that the digital camera exposure will be over before the disposable flash goes off.”
If you can program control of a hardware-based time-delay, to the millisecond, and can thus trigger the flash to occur/appear between the camera’s flash’s (exposure) and the last instant in which the entire field of the medium is simultaneously being exposed – or even slightly beyond that, depending on the class of camera in use -, then you could open a wide, wide range of photographic possibilities based on the temporal relationship between the two principle contributors to the exposure…
I agree that the camera is the perfect project case. It is also the perfect thing to put on a tripod or other stand.
You also wrote:
“the flash behind the stencil shining through the lens. I am convinced that I can use this concept to make a slide projector, and have worked on it, but I need a bright light source and finally gave up.”
What about a cascade of capacitors instead of the (likely) single, small-ish-capacity found in the disposable? You could then arrange to dump the smaller – even much smaller than the original – capacitor through the flash tube, then refill that cap from the ‘cache’ in the larger capacitor, cyclically during use. This would be intended to deliver a high-availability, non-photographic-strength, cool-running light. Adjust the timing, with particular regard to the persistence of vision, and the effective ‘frame rate’, of the human eye-brain, and shoot for a projector.

That’s a nice transmitter project! I was wondering whether the 2pf coupling capacitor gives you enough isolation from detuning when your hand gets near the antenna. This is a problem that I had when using a circuit like yours, but I didn’t have the capacitor.
With respect to walied’s question about a receiver – how about just using an FM broadcast receiver as the receiver? No need to make a receiver when they are already one of the most common consumer electronics products. And inexpensive at that.
I think ultralights are the way to go if you want to fly cheap. I had 12 hours in a Challenger but the instructor would not allow me to solo in his plane. I had to go the other route and train and solo in a C-150. I am considering returning to flying a fat ultralight like a Challenger II.

I have an ipod video, and recently the hold button hasn’t been working. I would push the hold button to “on” and sometimes the icon won’t show up, and it’s not holding like it’s supposed to. Sometimes it will turn on right away, but after about 20 seconds the icon will turn off by itself. I haven’t misused it, like dropping it or getting it wet. I don’t understand what’s going on with it. Has anyone else had this problem besides me?

Eu penso que os povos devem saber. Eu sou um occultist que esteja estudando o occult toda minha vida.

Este era um vÃrus deixado cair para provar que (os angels do sangue de Satan ou de Demonic eram muito reais) os sinais olhar para fora para são (lotes dos olhos vermelhos) do caixão toda a hora ou mais do que o normal. Riscando o corpo, e o bebê gritará em gritar mau da maneira engraçada. O poço I foi a Glastonbury e a rua e eu não poderÃamos acreditar a quantidade de povos com os sintomas acima.

About 6 years ago, I was one of the first to order the plans.
On and off, it took about a year to build it. I’ve re-skinned
the wings twice (the first lasted about 3 years, and I’ve gotten
better at applying sealant and UV protection). I use a 440cc kawa
engine. I don’t fly it to get anywhere in a hurry…I fly it for fun.
If you want one-person transportation, buy a motorcycle (or bicycle).
Go to “Settings”, “Clicker” and make sure it is set to “Both.” It did the trick for me.
The 7-pin connector is the same s-video as the 4-pin the 7-pin has other uses as well but all four pins on the 4-pin male line up correctly to the 7-pin female. so its the same connection.

Sure it can be, it’s nearly the same chip. The smaller one is just a compact, low-power version for small laptop mice. AFAIR it just lacks internal diode controlling circuit. Other than that, they use an identical control scheme. In fact, all those sensors, dating back to the earliest models made by Agilent, use the same interface.

ahi te va en español, necesitas saber para que es cada cable, abre el control, lo mas seguro es que tenga el integrado 4021, busca la configuracion de este integrado y verifica para que es cada cable, forsozamente son 5 cables
the capacitor is a ceramic capacitor, if this helps
i recently bought an svideo to rca cable for just so cheap i could not resist.
unfortunately it doesn’t work. the laptop believes there is nothing connected to its svideo port and just refuses to turn it on. if i connect via svideo to svideo first and then remove the cable and connect the rca cable, it works. :-\
so there must be one of the connections missing on those cheap cables. anyone have clues? anyone have a schematic of the cable? like all things i guess i have to do this myself to do it right.
Wondeful for my experiment, i test and rewrite my impression. God job
I purchased the internet download plans some years ago and was able to print them off right away.UnfortunatelyI have been unable to build tyhe plane due to a wife who says NO – I had already designed and built an ultralight which flew fine, but the guy who bought it was an idiot & crashed it. Unfortunately he was unhurt as he continued to fly very unsafelyand finally lost his licence. I would love to build the affordaplane as it is so simple and the plans so easy to follow.
I agree with your point. I think its a nice view to your topic.
i gave my nes a bath in soapy water dried it and it worked like new hehe
Take the nes compleatly apart to were all u have in your hand is the circuit board run soapy hot water in a dish bucket dip the board in the water and let sit for 4 or 5 hours then take the board out of the water after it is cold rinse it in semi hot water whle cleaning the contacts with a sponge being careful not to bend the resistor clean the grounded metal plates and dry the board with a womans hair dryer once compleatly dry get a cloth and dip it in rubbing alcohol and clean the contact again then dry with cloth. once compleatly dry put the board back in place and put the nes back together. Now we move to the games. Take the games you have apart till all u have is the boards and repeat the same steps above that u did with the nes board and all will go well have fun and i hope this fix your like it did mine.
Purchased my plans for the A-plane a few weeks ago. Like the design, do see where some improvements could be made but in whole the plans are better than many that I have seen. I have my shop all set to build, table built and hope to order the metal next week. I have tried a number of sources (live in southern Ontario, Canada) and Aircraft Spruce (Canada) has better prices than the metal shops in Windsor and London. Although I have much experience with aircraft, this is my first build.
seems to work from a video i’ve seen, although the audio seems very low, maybe an op-amp would help
Can adding moth balls to your gasoline damage anything in the engine?
How would you increase the power output of this? I’m curious as to how this kind of circuit works. Once you have this done, would it work as a sort of low power preamp, almost, so you could feed it’s radio frequency output into a power amp, into an antenna?
I guess I would need to look at regulations about broadcast power regulations before I built one of these on a large scale. I’m just wondering about how you would scale this up, and how a tuner, you know, tunes, and whether it would be possible to just amplify that.

Holding down the Play/Pause button for a few seconds should turn the ipod off unless its an ipod shuffle. I have a 30 gig Ipod video and run it on a pc. Every once in a while (every other time i try to turn it off) the play/pause doesn’t work. Then i have to hard restart it by pressing menu+center button a few seconds after that things seem to go back to normal. Flipping the hold switch never did anything for me but I imagine that could be an issue with some people. Also I set up my ipod to have a sleep button on the main menu, it only works after waiting on that menu for at least 5 seconds apple is so unintuitive.
Thanks for the full article. You were right that it was confusing..
ipod’s product sounds good and techy…..but all of these are for marketing strategies only….quality and performance revails the true product itself…………headache….sucks…

“There is a world inside of you. And you will ask for more”
There is a world inside of me, it is neither physical, nor spiritual, yet it is begging for release. It is infinitely expanding within the shell of me. It begs to become.
Through the coming convergence of science and technology, the collective expansion rate will race, match and then overcome that of the very limits of the Universe itself.
A new wave of evolution.An existence beyond limits and boundaries. Expand forth from within…break shell after shell of ignorance, collapsing, igniting, and dreaming away into being. Limitless. Forever.

Please don´t try this. A battery needs a special charge depending on its composition. Using only a resistor and a diode it is not a good idea. Battery life will reduce drastically.
believe or not but all cars can work on water !

I have been into controller modding for a while now and the nes is still the best to play with. The circuitry for the ps2 controller fits nicely inside, it fits even better in the snes controller. Getting these controllers to work with our newer systems is necessary for those of us using xbox’s or ps2’s as emulator systems.
Doug, you’re just too dumb for pong. Truly.Somebody get this guy a hoop and a little stick or something..
They “upgraded” the screen saver now. It looks nothing like old school pong. How disappointing.

There are at least two diff probs here. 1) Ipod is hung and won’t respond to turn off signal (pressing bottom of wheel) at all. This happens sometimes when, for example, your ipod is connected to a docking device and you turn it off while pressing bottom of wheel wheel – then you immediately unplug it the ipod, which lights it up again — sometimes it will won’t then respnod to a a shut off signal by pressing bottom of wheel. This prob has been recurring on opds for years and can be fixed with a reset.
2) When you press the bottom of the wheel, the ipod turns off for about a half second or so and lights right back up again. This prob has an unknown cause and is not fixed by a reset. If you restore, the prob will be fixed UNTIL you reload you music files onto the Ipod – then the prob automatically returns. Some suspect this prob has to do with a file problem and ipod’s inability to appropriately deal with the file problem.

I ordered the E-plans on Monday, Jan 14th and received them on Friday, Jan 18.
Not 48 hour service, but good enough.You can use PayPal to oder the plans.
If you don’t get them, you don’t pay. A cursory review of the materials
indicates good layouts and plenty of info in the builder’s manual.
Hi, I visited your blog just now. Very nice. Thanks!

I have the layout on my work table done and have all the gussets redrawn. I found that even after playing with my printer, the full size gusset plans came out at 94% of full size. After I had done my layout on the work table, I had to redraw all of them to correct size. I also found the angle on gusset A and gusset D to be incorrect. I have also changed gusset H to give more support forward. I am hoping to make contact with some other builders, to share solutions to some of the problems. EG I am using the suspension springs and disk brakes from a mountain bike, which required a redesign of the landing gear.

http://www.instructables.com/id/SAYNK7DF9T3NNL7/ helped me with this project by telling me to directly solder the capacitor between pins 3 and 4 on the s-video plug and then by soldering wires from pins 1 and 2 to the rca ground and then soldering the wires from pins 3 and 4 to the rca signal. i don’t remember what size capacitor i used but it was ceramic and between 10nF and 470pF closer to the 10nF side. works great. love saving dollars by putting my pack ratted shit to use. if you break the plastic pin out of a ps/2 connection, and the top two terminals, guess what. you have an s-video plug.

When I first found out about Jes I wasn’t 100% sure if what you said was true, but then I said to myself-what do I have to lose?
Now,after something less than 2 years of using the Jes-Extender I am 1000% convinced that it works.
Unfortunately I don’t have the time to use it 8 hours a day like has recommended (I did that in the first 3 months only) but I use it 2 hours a day (uninterrupted).
I don’t keep notes of the size changes but it has definitely enlarged in size and girth. The most important thing however is that my erections are stronger and durable,the sensation is much better and my confidence now is great!
I am very satisfied with the quality of the product. The only thing I had to purchase since then was silicone tubes. In general, I cannot express how grateful I am. I would say that the Jes-Extender was the best gift I’ve ever made to myself!

Dwight,
I had the same problem with scaling on printout…until I dleted the margins. Then the test page printed to scale & I continued with the rest. The only page that did not print to scale was the rib layout (in severl pages) from theupdates section. i just drew the rib using the given coords. All the gussets fit perfectly, except the A gusset (which is noted in the plans. I redrew this onbe to fit the plans.
I’m just starting my project, so we will likely encounter similar problems. I am tilting the top fuselage member slightly so that the wing attach brackets can be mounted on ceterline to this member, not 1/2′ from the edge as shown in the plans.BTW, I’ve also decided to re-design the gear to a spring-type suspension, but keeping it light.
