Some interesting things I found recently:
We have been working in a concept for a different type of music instrument. Putting together some feminist theory of music, some love for strange sounding animals, a laser engraver, a bunch of sliders, some orange LEDs and a lot of patience, we created the Peacock.
The Peacock is an instrument for live performace or personal exploration of both live and digitized sounds. You can get sound from an SD card or record it through its mic-in. The sound will be looped and affected in different ways by different effects and digital filters.
To show off microcontrollers and our kits during the event, we built a sound meter which uses the piezoelectric buzzer (included with our USB NerdKit) in reverse, as a microphone. This provides an opportunity to demonstrate a single transistor amplifier, to make the signals from the piezoelectric element big enough for the microcontroller's analog-to-digital converter (ADC) to read.
The Drone Lab is an analog sound module specially designed for making dense, rich drones.

I wanted to design something that could fit in your hand but still deliver some heavy sound.
