Although many Raspberry Pi users are enchanted with the concept of such an inexpensive computer, you can also embed it into larger projects for all sorts of games, effects, toys and dare we say educational uses.
One simple but fun use of the Pi is to make a sound-board - that is, a device that will simply play various sound files at the press of a button. These could be used for all sorts of reasons, such as exhibitions, educational tools or just to fool about.
One example has been documented by Matt Richardson and Shawn Wallace from Make:, who show how to make your own version with a minimal amount of external hardware. Their version uses three buttons, plays .wav files and is coded in python.
It's a simple project that can be expanded easily and also shows how simple it is to integrate external circuitry with a Raspberry Pi. For complete instructions, visit the project site. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking for a more permanent way to mount circuitry to your Raspberry Pi, check out our new PiBreak - the prototyping board for the Raspberry Pi. It provides labelled breakout pins for all GPIOs, a large prototyping area with solder pads, and power rails for easy power connection:
Furthermore the PiBreak also includes mounting hardware to firmly attach it to your Raspberry Pi using a nut, bolt, and spacer - and is compatible with all revisions of both model A and B Raspberry Pi computers.
