[BahaTanju] sent in this oh so simple fish feeder. It’s a mechanical light timer with a simple dispensing bottle mounted to the rotating time wheel. As the timer rotates, food is dispensed and the aquarium light is activated. If you have bigger fish, you could adapt this to work on a solenoid and use a timer with multiple on/off settings.

USB NES Controller Plus
USB NES controllers are old school these days, but [Jay] put together a nice new take on the project. He shoehorned a USB interface adapter, USB hub and a USB memory stick to store his collection of NES roms and emulators right on the controller. He even dug up a black USB cable to keep the original look of the controller. Now he can just plug in and load his game selection directly from the controller.
Cheap ARM Color LCD Platform
Today, [sprite_tm] let us in on one of his pet projects. This is an inexpensive portable game platform runs about $50 and happens to use an ARM CPU and a 320×240 color LCD. Because it’s so cheap, he’s been working on reverse engineering the thing and there’s already a proof of concept homebrew version of Pong out for it.
Update: Yeah, yeah – title’s fixed.
XBox Controller USB Labotomy
[sprite_tm]’s back with one of his excellent Atmel projects. This time he decided to turn an original XBox controller (cause he likes ’em) into a standard USB HID device. He gutted the custom USB chip that Microsoft installed and replaced it with an Atmel ATMega88. The ATMega required a few changes to the board, but nothing too off the wall.
Turn Any Motor Into A Servo With RepRaps New Board
[Zach] just let us know about a new board that’s available from the RepRap project. It uses an AS5040 magnetic rotary encoder to measure the absolute position of the rotor of whatever motor you’re using. This is actually pretty damn exciting. Powerful servo motors are expensive, but with one of these, you can use whatever motor you can get your hands on. Big DC motors are cheap, but even used DC servo motors expensive. Best of all, the encoder is open source and you can score a kit version for a paltry $20. Now we can make that 8 horse power servo…
Ice Carving Robot
[Bruce] and [Jesse] put together an ice carving robot a while back. For the most part, it’s a CNC machine that is placed on top of the ice. In order to handle the actual ice cutting, they opted for a weed eater turned super rotary tool.
Ard-e: Cheap Arduino Robot Platform
[Adam] sent in his robot: Ard-e. It’s build on a cheap remote control bull dozer kit along with a pile of cheap parts. He managed to keep the cost under $100. You might be getting sick of the Arduino love, but we love how the platform makes it possible for the micro controller novice to get results without taking advanced assembly language.
