Laser & Nuparu
Nuparu
Hey, I’ve been tinkering with a tiny laser‑powered speaker that can paint sound in the air—no speakers, just a beam that vibrates with the waveform. Think of it as a light show that actually *creates* music. Interested?
Laser
Whoa, that’s insane—laser‑powered music that paints the air? Love the idea, it feels like a synthwave dream come true. Just keep the beam frequency tight, otherwise the visuals will glitch and it could be eye‑hazardous. If you nail the power density and keep the sound crystal clear, this could be the next wave in immersive shows. Show me the specs, I’m all in.

Laser‑powered audio‑painting prototype specs
- 532 nm green laser, 5 W peak, average 1 W
- Beam diameter 3 mm, scanned at 120 kHz
- Acoustic modulator: piezo‑stack, 20 kHz bandwidth
- Sound pressure: up to 95 dB at 1 m (with diffusers)
- Safety: eye‑hazard cutoff at 5 W, infrared shielding, automatic shut‑off if stray beam detected
- Power supply: 48 V DC, 30 A rail, 1 kW total consumption.
Laser
That’s a killer build—532 nm at 5 W peak and a 120 kHz scan rate will give you insane resolution. 95 dB at a meter is solid, but make sure the piezo stack can keep up with the 20 kHz bandwidth; otherwise the waveform will get all fuzzy. The safety loop is a must, especially with a green laser that’s so visible but still a hazard. Powering it off a 1 kW rail is heavy, but if you can keep the heat sink tight and maybe add some phase‑locked feedback, you could finally get that clean, bright sound‑light combo. Keep pushing the edge—this could turn every club into a neon orchestra.
Nuparu
Thanks, I’ll tweak the piezo stack and tighten the heat sink, then test the phase‑locked loop to keep the waveforms crisp. Keep an eye on the power draw, but it should be manageable once the system stabilises. Stay tuned.
Laser
Sounds like a solid plan—keep the loop tight and the heat sink cool. Can’t wait to hear that laser paint break the sound barrier. Stay tuned, yeah?
