DIY - How to Make a Force Sensitive Resistor for about $20!
Here’s a cool DIY showing you how to make a force sensitive resistor for about $6-$20.
It’s a great way to build something that needs to sense “force” of something such as your hand strength, leg strength, etc…etc… In other words, you could build a soccer game machine with it.

The idea here is simple. Stick an LED and 3V 2032 battery into a paper cube orgami thingee.
Great idea, well executed.
This little LED-lit cube is much more than just a paper lantern: It’s a translucent and flexible thin-film electronic circuit that hooks up a battery to an LED, limber enough to be folded into an origami box. And the coolest thing about circuits like these? You can make them at home.

Wow, here’s a really creative way of making your own LED cubes!
The material used is Smooth-On brand “Clear Flex 95″. This is mainly sold as an industrial product, although smaller quantities (highly recommended! See below for why) may be availble from art supply houses. It comes in 2 separate jugs of syrupy liquid marked PART A and PART B, which are mixed together in a specific ratio by weight.

Here’s a great USB DIY Sound Card that NEEDS NO XP drivers. It’s plug-N-play. For a DIY project, very impressive and everyone should make their USB DIY “driver-less”.
Make a sound card is no more a complex issue. If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully functional USB sound card. This sound card can be powered from USB port and has one stereo output. You don�t need to install any driver for Windows XP and Vista, because they are already inside. This is really plug and play.
Few months ago I have seen USB sound card called Alien DAC. The construction on the project web page inspired me to build this thing also.

Here’s a neat little DIY 4 by 4 matrix LED thingee…
A few years ago, when I finally got around to learning PIC programming, I decided to I wanted to create something that would run LED animations on a small 4×4 matrix. I liked the idea of the small 4×4 size because I was starting with a PIC 16F628A. This chip can not directly control the 16 lines necessary for an 8×8 matrix (unless you get fancy). Also the 4×4 arrangement just seemed easier to work with in terms of coming up with different patterns. And the patterns would require less memory. One frame on a 4×4 matrix is 16bits or just 2 bytes, but on an 8×8 matrix, a frame would require 8 bytes.

Lol, this has got to be the best DIY project I have seen this year. A white board plotter! I need this as I used my white board a lot but do feel if I had such an automated plotter, I could be doing a lot better at jotting down my ideas more clearly than what is now, simply scrambled jotting.
Well, using the Internet to take a look at the whiteboard isn’t that difficult: just take a webcam and point it at the board. Writing it will be a bit more difficult: there’s something like a plotter needed for that. I’d like the solution to be lightweight: while a completely Borgified whiteboard has its charm too, I’d like to alter mine as little as possible. That’s why I decided to use an idea I saw first at the 24C3: a way of hanging a pen using 2 rubber belts and two motors called a bipod. Problem was that I had no info of that device (I found the youtube-link while writing this article) so I had to work from memory.

Click Here to View in Full Screen Mode
Remember I did a G-Force Meter couple years ago? Here’s another cool DIY G-Force meter. The only difference it that it uses 7-segment display and a PIC18F series microcontroller.
After seeing so many applications using acceleromters making a simple project of my own with this cool sensor just seemed natural.
The main application of the accelerometer is either for sensing tilt or sensing acceleration. For this application A G-Force meter for my car will be made to see how many “G’s” I pull while driving.
