Background

A co-worker of mine when I was at IFTTT built the circuit that started this project. We worked on polishing it up together. I designed the PCB and the enclosure while he worked on the audio and software that drove the four small piezoelectric elements. Four piezo elements meant polyphonic audio. I wish we had a video of this thing in action.

PCB Design

I designed and ordered the PCB through Upverter. Check out the design here

Here's the assembled project impplay assembled parts1

First test assembled with the battery. It works great! impplay assembled w battery

Enclosure

I ended a print early to make sure I got the dimensions of the board right in the design file. It has a charge controller, a LiPo battery, and then the custom PCB on top. impplay partial enclosure

Printing on the Makerbot! impplay enclosure makerbot

I thought it looked pretty nice. Very 80s. I used Sugru to snug in the PCB and keep it from rattling around. impplay completed enclosure impplay completed open
