SFX4 - a Model Sound Effects Module

This is a commercial project using AVR-USB, sources are not publicly available. SFX4 stores multiple digital sound clips up to a total of 3 minutes, and plays them back through a 9 W PWM power amplifier and loudspeaker. Sound clips are stored in a 4 MByte FLASH chip. Up to seven different sound clips, including a semi-proportional engine sound, may be stored in one module and two sounds may be played simultaneously. Sound Clips are downloaded/uploaded through USB.

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.
