Open source Atmel AVR microcontroller kits…
Wow, check out these Atmel AVR Microcontroller kits for Linux – USB and parallel port versions, the best (I think) is they come with bootable CDs Link. Related: AVR projects – Link.

Hacking LED Christmas lights for low voltage use
John writes – “I saw this and just had to share. You know those very neat LED Christmas lights that you could find on the clearance tables a few months ago, you remember them now because your going to kick yourself for not buying a crap load of them. Anyway, Joe has a tutorial on […]
Build a home ceiling-mounted kids gym and climbing wall
Creatrope has another fun project, a home kid’s gym – “This ceiling-mounted kids gym and climbing wall has seen a lot of use, and was easy to build once I figured out a strategy. It was around $125 worth of parts. It was inspired by a friend who has an even more elaborate one. It […]
Homebrew through plating machine
M writes – “I got sick of waiting for my PCB’s to be made externaly and therefore wanted to be able to produce PCB’s for my prototypting needs by myself. Now, it is not too difficult to create even double sided PCB’s at home. However, having the vias conect the two layers by hand is […]
HOW TO – Make a garage monitor
Joe writes – “Need to know if the garage door is open? Need to know if you pulled in far enough for the door to close without hitting your bike? Need to know all this with web access… I present the garage monitor 3000. When the car reaches the right spot, the LED turns from […]
HOW TO – Drive a lot of LEDs from a few microcontroller pins
Westfw writes – “Using the fact that many microcontroller pins have three states (+V, GND, or “high impedence”, you can drive N*(N-1) LEDs from N pins. So the little 8 pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs on its five available output pins, and still have one pin left for […]
Concept = Bling binary LED watch
Todd Bailey has made the coolest watch ever, it’s a clear binary LED watch, all on a rainbow ribbon cable – PDF Link. Related: HOW TO – Make a binary watch – The 01//atch – Link.
