When we first posted [Matthias_H]’s USB reader for SNES game carts, it was met with enthusiasm. The snega2usb allows you to play SNES and Sega games on your pc right off the cartridge. The latest revision is even more amazing than the first.  [Matthias] has added the ability to read Sega Genesis/Mega Drive cartridges as well as the ability to save games directly to the cartridge. The board has also been updated from the rats nest it used to be to a smart looking dual sided PCB. So far [Matthias] hasn’t had any trouble reading cartridges, even ones with the SuperFX chips. [Matthias] also launched a site for the project where the lastest information on its development can be found.  [Matthias] is getting close to a production version which will feature better firmware, console quality connectors and a shiny case.

80 Gig Drive Inside A Game Boy

September 4, 2009 by 19 Comments

[_n3o_] put together a nice external storage mod by fitting a 2.5″ drive into a broken Game Boy. This mod fooled quite a few people because it appears that the device still plays games with the drive stuffed inside of it. Sadly, this is not the case. The reflective backing has been removed from the screen and replaced by a piece of paper with a graphic printed on it. The LED from the hard drive was moved to the battery indicator for the Game Boy for added realism. There is no build log for this project but [_n3o_] did give a short explanation of it in a forum post. You can see two more pictures of the project after the break.

USB Gameboy Cart

[Jose Torres] sent in his latest attempt at creating a custom Gameboy game cartridge. We’ve featured his projects before, and he’s come a lot closer over the last 2 years. He’s aiming to create an easy interface for homebrewers that doesn’t require any other special equipment. In this revision, he’s using a PIC and a memory controller to interface between an SD card and the Gameboy. The cart also has USB support for uploading files to the SD card and reprogramming the PIC. Because it’s just USB mass storage, it will work on almost any modern OS. He’s currently testing the device, but hopes to be selling them soon for $40.

Arduino USB Host Shield

UsbHostShield

Circuits@Home has been journaling their development of a USB host mode shield for Arduino, which could bring the platform a veritable explosion of mass storage, keyboard input and countless other peripheral options (and a corresponding raft of new hacks). Currently at the prototype stage, a ready-made shield and library are forthcoming, so keep checking back. Meanwhile, for embedded developers wanting to learn the ropes of USB, the in-progress articles will likely provide some valuable insights.

Reverse Engineering USB Drivers

August 20, 2009 by 17 Comments

When [Jespersaur] purchased a Luxeed LED keyboard, he was disappointed to find that the drivers were not open source and didn’t support all the features he wanted. His solution? Hack the drivers that come with it, and implement his own. In his article, he gives a basic rundown of beginning reverse engineering by multiple methods and a brief introduction to libusb. For the Linux drivers, check out [Kurt Stephens]’s site, where he supplies a link to the source code, instructions on building it, and a tutorial on sending commands to the keyboard.

Tiny Bluetooth Teardown

The folks at SparkFun were startled by how small USB bluetooth adapters had become so they split one open. They noted a few interesting design features. It has a small folded trace antenna on the board edge. The metal USB housing acts as the RF shield. The bluetooth IC is an AS3620QA. Now we wonder what those tiny Buffalo drives look like inside.

1wire Attic Cooling

[RagingComputer] built this 1-wire attic cooling fan. He’s using an Ubuntu server loaded with OWFS to control everything. The 1-wire temperature sensor is interfaced using USB while a serial x10 module sends out commands to be received by another x10 module near the fan. Back in the day we had covered a linux home automation project. We also covered HVAC hacks such as the smart attic fan and a 1-Wire HVAC monitoring system.
