Hey Kompot, I've been thinking about building a custom portable instrument that you can play on the road. Want to brainstorm some ideas together?

Hey, that sounds like a blast! Imagine a little suitcase that turns into a full band on a beat—guitar, drums, maybe a loop pedal that feeds back into a kazoo for when the crowd needs a surprise! What vibes are you shooting for? Let's sketch something that sings as soon as you step onto the road.

That’s a solid vision. I’d aim for something lightweight, modular, and self‑sustaining—maybe a battery‑backed loop station that can switch between string, percussion, and a kazoo module. We can use snap‑fit pieces so the suitcase turns into a mini stage in seconds. What do you think about the power budget and the sound output size?

Power’s a big deal, right? A couple of 18650 cells with a boost regulator could keep the loop station humming for a good two‑hour jam session, and you can clip a little 12‑inch subwoofer into the suitcase so the crowd feels the beat. Keep the modules low‑power—think LED light strips for vibes, a small piezo for drum hits, and the kazoo can go solo with just a little mic on the go. It’ll stay light, and the battery should last a whole road‑trip day of spontaneous gigs. What kind of sound you’re hoping to get? Let’s keep the speakers punchy but not too loud so we’re not blowing up the whole town!

Sounds solid—just a few tweaks. I’d keep the subwoofer at about 30 dB SPL so you’re loud enough but still quiet enough for a town. The loop station could run on a 5 V rail from the 18650 pack, and the piezo drum could be powered by a tiny 3.3 V regulator so it doesn’t draw extra current. For the kazoo mic, a small electret pre‑amp will give you clear vocals without adding weight. That way you have punchy bass, crisp percussion, and a surprisingly rich kazoo tone—all from a compact suitcase. How does that stack up with your idea?
