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.
FABR: Another 3d Printing Project
[Lou]’s been working on his own 3d printer: fabr. We find it appealing because the entry cost is quit a bit lower than something like the reprap. 80/20 isn’t that cheap, but you don’t need a large commercial laser cutter to build the chassis. The steppers he used appear to be inexpensive ones that can be salvaged from dot matrix printer. To drive it, he’s working on a custom microstepping board and hopes to eventually develop an Arduino shield to control the stepper drivers. That’s right, it’ll get an Arudino to act as the CNC control interface.
Clove 2 Glove For One Handed Input
[Christopher Mitchell] (previously on Hack a Day) has come up with a rather interesting input device. The Clove 2 glove is a Bluetooth data input interface. The goal is to be able to “type” without the use of a traditional keyboard. Key strokes are achieved through finger movements. Your computer simply sees this as a Bluetooth HID device and some software translates it for you.
While it may seem confusing, he’s designed it to be very similar to typing on a keyboard. Each finger movement or combination is a key stroke. Just like typing on a regular keyboard, there are modifying strokes such as ALT or shift that effect others. Most common used keys require the least combinations of finger movements.
