Pelican Case Xbox 360

pelicanxbox

[Ben Heck] has put the final touches on his Pelican case Xbox 360. This prototype was constructed for use by troops stationed overseas. When he announced the project in October, he already knew some of the hurdles he would face. An industrial Velcro style product is used for all component mounting so the air/water-tight seal of the case remains intact. He sanded the surface so that it would stick better. [Ben] mentions that he ended up using less Velcro than he planned on because it held so well. Not being able to cut the case meant the DVD drive had to be converted to top-loading. The tray movement limit switches have been relocated so they now respond to lid position. He regrets not being able to motorize the lid, but let it go since this is still just the first attempt. Extra copper was added to all of the heat sinks to improve cooling. This Xbox is for sale and he’d love to hear from anyone that wants to put it into production. The write-up has a ton of pictures and you can see a video of it below.

Giant LED Lamp

[guyfrom7up] must really really love LEDs. When he needed some lighting, which would obviously be LED powered, he chose to actually build a giant LED. Well, he didn’t actually build a giant functional LED, but rather an LED shaped diffuser for some high powered LEDs. He takes us through the process of first creating a wooden model, using that to create a mold, then forming the final diffuser.  The final product is very well done, and instantly identifiable by any geek.

Multitouch MAME Cabinet

[rdagger] sent us this really well done multitouch MAME cabinet build. He ha penned to find a used, and fairly worn cocktail cabinet. The monitor was damaged, keys lost, and internals had been home to mice for some time. He promptly tore out the old guts, replaced the smelly mouse damaged base and began building the projection system. For touch sensing, he’s using a web cam with the IR filter removed to detect disturbances in some IR laser beams. We’re not completely clear on how he mounted the lasers, he skips over that part.  There’s nothing groundbreaking in the technology here, we’ve done multitouch many times before. This project stands out in its execution. [rdagger] has done a fantastic job, the construction looks fantastic.  Check out a video of it working after the break.

Parts: 1K 1-Wire EEPROM (DS2431)

1keeprom-450

The Maxim DS2431 1K EEPROM is 1-Wire device that adds storage to a project using a single microcontroller pin. We previously interfaced a 1-wire thermometer, but this EEPROM is slightly different because it draws power directly from the 1-Wire bus. Grab the datasheet (PDF) and follow along while we read and write this simple 1-Wire memory.

Guitar Hero Cymbal Remake

[Matt] found, like many people, his Guitar Hero: World Tour cymbals left much to be desired. They were only detecting hits intermittently and starting to crack and fall apart as well. While he was waiting for his warranty replacements to arrive, he just couldn’t help by try to make his own improved version. Using about $25 worth of parts, mainly consisting of plastic plates and some neoprene material, he managed to make some pretty fantastic replacements.  A video of them working might be a nice addition, but the writeup was pretty detailed otherwise.
