Emergency Beat Kit / Boldport Superhero Mod

thingiverse

This thing is a small electronic art object, based on a kit by Boldport, and created for a short music video: https://www.youtube.com/watch?v=hv2VlZv5Mfg You can watch that video (perhaps slowed down :) for full assembly details. The 3D printed case is the width and height of a standard credit card, but thick enough to hold a CR2032 coin cell. The kit's circuit board snaps into the center, and the case also provides a piezo disc button that generates a pulse which charges the capacitor and FET gate, letting the LED glow for a while. Prints without support. Watch out for warping and overextrusion. If I were to do this again, I'd make the front wall of the piezo button a bit thinner and the back section a little thicker, to improve the efficiency. Right now a lot of the force goes into flexing the front case enough that the back makes contact.
