This is an 8 ohm attenuator built using an 8 ohm L-Pad. 4, 8 and 16 ohm versions are possible. The 4 ohm version would be built using a stereo 8 ohm L-Pad with the terminals wired in parallel. [more]

If youโre looking for a build-it-yourself, standalone, USB harddrive based MP3 player, this may be of interest to you. Originally conceived as a replacement for a CD player, this unit sits on the shelf next to your stereo and connects via standard RCA line-out audio connectors.This is an open-source project. Full hardware schematics and software source code are freely available on this site. As long as itโs for non-commercial use in whole or in part, you may use and modify this design to your heartโs content.[more]

The Wireless Interactive Media Player (WIMP) is a 4th year project at Carleton University that involves the design of an MP3 stereo with a wireless link to a PC. The wireless link allows users to remotely download songs and control their WIMP MP3 stereo from any room in their home, regardless if where in their home the WIMP stereo is situated.The idea for the WIMP project came from our desire to work on a more “hands-on” project thanmost of the traditionally abstract, and theoretical projects that offered by Carleton University.The design of the WIMP is based on inexpensive, off the shelf components that include an MP3 decoder, a microcontroller, CompactFlash memory and a wireless standard.

This is a musical sensor interface using the CREATE USB microcontroller: a hybrid network of tangled audio technology, based around turntable decks, guitar strings and optical sound designs.This project wanted to merge several of the most crucial audio technology inventions from the previous century into a hybrid object. The inspiring technologies include the phonograph, optical sound on film, the amplified guitar, and the computer. Each represents a different approach to generating, transmitting and/or encoding vibrations, from the spatial through the electrical and optical to digital bits, and each with its own expressive leverages and characteristic morphologies. This project embodies a continuum of audio technology interaction from the most physical hands-on of the vibrating string, to the abstracted turntable control of pre-recorded data, to non-physical control data in optical and electronic form, and finally to the completely abstracted and malleable digital domain.

This project is fun for someone with intermediate to advanced electronics skills who wants to make cool sounds. It makes a great first synth project but is interesting enough for the seasoned synth person too. The board includes 1V/oct scale adjustment trimmers for the oscillators You will get a couple (maybe three) octaves of in tune scale. The Sound Lab Mini-Synth is a LOT of fun to play with and makes some very cool sounds. If you like electronic music you will definitely have fun with this. If you have a sampler you can use this unit as an analog synth sound source to make excellent samples with.[more]
