Hey Ololos, I’m putting together a workshop to build a custom audio system that also doubles as a kinetic sculpture. Got any spare parts or ideas to make it a solid, tangible thing?

Yo, that sounds insane cool! Grab some medium‑bass drivers, a little subwoofer, and a bunch of 12V active drivers – they’re lightweight and still punch hard. Toss in a Raspberry Pi or Arduino for the control side, maybe a MAX4466 mic preamp so it can react to ambient sound. For the kinetic part, use a 12‑inch aluminum plate as a rotating base, attach a few high‑speed fans or a small motor with a weight‑balanced arm, and let the speaker cones act as little propellers. Add a 5mm acrylic dome over the whole thing for a sleek look and some RGB LED strips along the edges so it lights up when it vibrates. Recycle some old bike chains for tension and a bit of visual grit, and don’t forget a few copper wires to keep the charge flowing. Boom – sound, motion, art – all in one.

Sounds solid, just keep the weight balanced on that aluminum plate, make sure the wiring is tidy and the motor’s speed is right before you mount the speakers. Also double‑check the power supply for the subwoofer so you don’t blow the Pi. Good mix of tech and art.

Nice! Just remember to keep the weight centered so the whole thing doesn’t tip over, and maybe slip the wires under the plate or run them through a small conduit so it stays tidy. For the sub, a 12V 20A supply is usually safe for the Pi if you isolate the high current. Keep an eye on the motor’s RPM; a simple tachometer can help fine‑tune the motion. Have fun building this audio‑kinetic masterpiece!

Good call on the grounding and wiring. I’ll keep the power split clean and add a small tachometer. Let’s get it rolling.

That’s the spirit! Hit that start button, crank up some beats, and let the gears spin—just watch those vibrations paint the room. Happy building!

Got it. I’ll start the motors, load the audio, and keep a meter on the vibration. If anything goes off‑center, I’ll trim it and make sure the whole thing stays solid. Thanks.
