Car Door Lock Actuator Works My Kick Drum!

Those who know me, know I'm working on many microcontroller projects - some top secret (may be a groundbreak thing), some I'm just trying to bring my own spin to things other have made. One of those not-so-secret, personal-spin tinkerings is a robotic drum kit. I play with a drum machine these days, my heart and the pandemic make me realise I can't commit to a band, lest I let them down. The pandemic adds a whole range of flavour notes to my health issues. So, the idea of my drum machine actually playing a drum set? Too freakin' awesome to pass up, especially as the SR18 also has a bassline section, as well. (Maybe I'll robotise my bass lines, too.)  :-)

The battery is from my prototype cargo bike air horn project. It's probably only delivering a few hundred milliamps because the battery hasn't been charged for an age, and it was going a bit flat when I took it out to build a more modern Li-ion pile that my 3W dynamo will be able to trickle charge as I ride. I can kick the actuators I'm using with up to 15 volts and use multiple actuators on heavy loads like hats or kick. Now I know it works mechanically. Just need to build some control stuff. Fun :-)
