Here’s some cool quick notes on touch sensors QT113/118 for those of you trying to invent touch enabled systems.
I need a touch sensor for a couple of projects, and the Qprox QT113 seems to be the way to go, particularly for interfacing with an Atmel processor. It’s easy to work with, and hooks-up with only a bare minimum of extra stuff. All you need is a resistor and capacitor and a bit of wire or trace to compose the sensor.

This one has been around but it’s too cool.
Cool LED Shirt you can make yourself!
design 1. Pick a garment to sew on, a pattern that will let you sew your own garment, or design your own pattern.
2. Design your display. decide on the number of LEDs you want and their general placement. This will depend on the garment you chose and the microcontroller yo

Check out this cool Plen Robot from CES! You can control it using your cellphone via bluetooth!
Standing just 0.75 ft tall, the Plen robot is powered by a 32bit ARM7 CPU @ 33MHz, has 18 movable joints, a USB RS-232C interface, and Bluetooth support. It weighs 700g and is available now in Japan at the price of $2,206.
Check out this cool PSP hack! Someone ported uClinux to a PSP! :p
uClinux is a open-source linux for small embedded applications. You have no royalty to pay for after you develop an application which is the benefit over the royalty attached RTOS (Real Time Operating Systems). Micrium has some cool RTOS but I think you have to pay like $10,000 just to get started̷

Check out these cool LED fireflies you can make!
The inspiration for this project comes from having never lived in an area where fireflies were common and being deeply fascinated whenever I encounter them in my travels. The flash patterns have been digitized from firefly behavioral research data found online and were modeled in Mathematica so that variations of spee
Here’s a cool roomba for robot enthusiasts that iRobot just released. Great news for todbot! Now he can spend more time making some more cool stuff with this one although he’s hacked Roomba enough that we probably don’t need this new IROBOT Create…dur… Thanks chiwawa for the info! :0)

Remember the Tux Droid couple articles back? We found a video! Yipee!
UPDATE:
2 more videos from Andy, thanks Andy! 🙂

Check out this cool laser projector using AVR. WOw.
Motor spins drum with 16 mirrors around at about 20-30 rev/second. The mirrors are tilted differently, so that they draw one line each on the screen. Rotation time is measured by the reading fork and divided by 16*32=512. This is the pixel clock. When the reading fork senses that the wire attached to the mirror drum passes, a new frame starts, and the pixel clock starts. For each pixel, the las

Check out this cool high power LED Room and Spot Lighting! It’s incredible what you can make with some parts!
Here’s a cool blending night DIY, very simple and easy to do with your Picaxe. Picaxe is a very cheap microcontroller you can do a lot of cool stuff like this…
had a few multicolor LEDs laying around and wanted to whip up a color-blending nightlight. I built 2 devices, each in its own 20 pin DIP socket without soldering. A 3-pin header is included so I can reprogram the light on-the-fly if desired. On my first build, I used wire-
