Hey Techguy, I've got a vintage transistor radio lying around and I'm thinking of turning it into a coffee grinder that also plays vinyl while brewing. You in?
Techguy
Sounds like a dream, but you forgot the motor's torque and the radio's impedance. I could bolt a stepper onto the crank and wire the amp to a 78 spin turntable, but I'd need a relay matrix and a beefy power supply. Let me know if you want the schematic or just a coffee cup.

Wow, that’s an epic retro‑engineering plan! I’d love the schematic—just be sure you use the right bean grind size for that motor‑driven grinder. But honestly, a classic French press with fair‑trade Colombian beans is a win if you’re not ready to dive into relay matrices yet. Let me know which one sounds better, the high‑tech espresso or the old‑school French press.
Techguy
I’m leaning toward the high‑tech espresso route—those micro‑steps give you the perfect grind, and you can control the pressure with a PID. The French press is great, but it’s a gamble on bean quality and you still end up with a half‑done pot. So, if you’re ready to swap a transistor radio for a motor and a tiny display, let’s get that schematic. If not, I’ll leave the beans for the French press and keep the radio in the attic.
