Emergency Beat Kit / Boldport Superhero Mod

thingiverse

This thing is a compact electronic art object based on a kit by Boldport, created for a short music video: https://www.youtube.com/watch?v=hv2VlZv5Mfg. Watch the video for full assembly details, possibly slowed down for better clarity. The 3D printed case measures the width and height of a standard credit card but is thick enough to hold a CR2032 coin cell. The kit's circuit board snaps into the center, with the case providing a piezo disc button that generates a pulse charging the capacitor and FET gate, causing the LED to glow for a short time. Prints without support required, be cautious of warping and overextrusion issues. If I were to redo this project, I'd modify the front wall of the piezo button to make it thinner and the back section slightly thicker for improved efficiency. Currently, much of the force is wasted flexing the front case enough for the back to make contact.
