This project was inspired by the music of Andrew Huang, Aphex Twin, SquarePusher, and Burial.
What it does
Our project uses an Arduino to digitize signals from Piezoelectric discs, which act as drum triggers. Additionally, the Arduino handles digital input from the electric maraca. These signals are processed and then passed to a computer via a Serial bus. This data is translated into MIDI signals and passed to FL Studio where it triggers notes, drums, and effects for creating music.
How we built it
We split up into several groups handling the MIDI, piezo-contact microphones, and music production between subgroups.
Challenges we ran into
The initial MIDI interface used a usb to midi bus to convert signals directly to MIDI instead of passing them through the Serial bus. In the process the converter was damaged beyond repair. To fix this we implemented the aforementioned solution.
Accomplishments and Demos
Our group is incredibly proud of our own Joey Carlson's cover of Shake it Off made using exclusively sounds recorded here at the hackathon, with a microphone built here at the hackathon.

What we learned
We've learned a great deal about MIDI and signal processing, as well as using electronics to enhance music production workflow.
What's next for the Illustrious Electric Maraca and Friends
My group hopes to make use of these instruments to create super cool blips, boops, and the music of the future.
This project was really shooting to win the best music hack here at hackcwru! Hope you enjoyed, have a great day.
