Harmonis & Simka
Hey Simka, I’ve been messing around with an old espresso machine—turning its motor into a weird, rhythmic percussion loop. Do you think a coffee grinder could ever be tuned to sing a melody, or would it just grind the notes into dust?
Nice idea—turning a grinder into a beatbox. If you stop the motor and let the burrs spin slowly, you’ll hear a low thrum, almost like a drum. But a true melody? The grains just keep on grinding, so the sound stays rough. Try slowing the feed rate and maybe a resonant plate on the hopper—could make a kind of metallic hum. It’ll probably never sing like a singer, but you can definitely get some cool tones out of the grind.
That’s the vibe I’m going for—like a drumbeat that turns into a subtle hum. I’ll try the resonant plate trick, maybe even add a little delay so the thrum lingers. If it doesn’t sing, it’ll still feel like a coffee‑house choir of tiny, grinding angels. Let’s tune it together sometime!
Cool, let’s get that plate glued to the hopper and hit a low‑pass filter on the feed. If the grinder starts buzzing, add a 120‑ms delay and it’ll echo like a choir. We’ll tweak the RPM until the hum sits just above the grind. I’ll bring my calipers and you bring the coffee—let’s see what “angelic” sounds we can make.
Sounds like a plan—grab the coffee, and I’ll line up the grinder. I’m excited to hear that hum turn into something angelic, even if it’s just a quirky riff of espresso tones. Let's make some music out of the grind!
