This isn’t a new project, but one I really like- a Hitachi TRK-8200HR + Fujitsu Stylistic 1200 Color Tablet PC running a MediaCar interface with custom skin in portrait mode to simulate a Boombox. The housing is an actual Boombox and it looks great. The Maker can also record radio right to the system too. Nicely done! Link.
Built as a one-man-band musical instrument- The Phoney Controller consists of a telephone housing, four Force Sensing Resistors (FSRs), an Analog Devices ADXL202 two-dimensional accelerometer, a BASIC Stamp II (BSII) microcontroller, a stupid “on-off” switch, and a cool LED! I am essentially using the BSII as a MIDI sequencer. All sounds at this point have to be generated from an external MIDI synthesizer. The FSRs and the 2D accelerometer are used to control various aspects of the sequencer. Link.
The Juicebox is an embedded computer designed to form the core of a simple ebook/MP3 player device. This little guy can do a lot and here’s a site that has pretty much everything you’ll need to start hacking at it. For $50 or under it might be a good platform for projects, but I think the Gameboy SP has more things you can do with them (We have a great article on this in issue 02!) Link.
