Enclosure for Electronic Cymbal Bluetooth Page-Turn Device Using ESP32 Devkit

thingiverse

I used an ESP32 Devkit to build a page turning device that acts like a bluetooth keyboard and triggers a page up key when hitting an electronic cymbal with a drumstick. It works like an AirTurn device, but instead of a foot pedal, it uses the piezo sensor in the electronic cymbal as a trigger. It's useful for turning pages on a tablet (works well with MusicStand) while playing drums when hands are holding drumsticks and feet are also occupied. The case is custom designed but based on this snap-fit enclosure box (https://www.thingiverse.com/thing:2866563/). The snap-fit lid holds the ESP32 in place, so the whole thing goes together nicely without any fasteners. On a second design of the lid, I added light tubes (filled with hot-glue post-print) over the built-in LED lights on the ESP32 and button press pieces that interact with the natural spring response of the built-in buttons which were inspired by this ESP32 enclosure (https://www.thingiverse.com/thing:3195951/).
