LEDLoad - an LED Display for CPU Load

LEDLoad has started as a neat CPU load display using a single dual color LED. The current release has been extended to support up to two tri-color LEDs. It is designed to use a free internal USB port of any modern PC and replace the power LED in the case with something more interesting. A host driver kernel module is available for Linux.

SNES/NES Gamepad and Atari Joystick to USB Adapter

NES and SNES are gaming consoles. When playing NES and SNES games with an emulator, nothing is better than using the original gamepads. This project converts the NES/SNES interface to USB, emulating a USB joystick. A project update from December 2006 brought support for Atari joysticks. See the project’s News section for a link. An illustrated guide for building a controller for 4 SNES/NES gamepads can be found here and here. There are also instructions for building the adapter without a PCB.
