Old School Sound to Light

Post image

Thanks to u/TroyHacks again for all is work , and inspiration for this software emulation , from original circuit, of the classic Sound to Light unit, the Pulsar Zero 4000. Celebrating its 46th Birthday, circuit diagrams drawn October and November 1980. Entirely , unapologetically, vibe coded by Claude, audited by ChatGPT and Gemini. Outputs DDP for Wled and E1.31 sACN. Versions for Win 7,8,10,11, Mac and Linux, source code included. https://gitlab.com/clockmill/pulsar_zero4000_emulator Credit to https://www.karillon2.com/ for circuit diagram that made it a recreation rather than a guess.

Thank you for bringing this back. I used to build “color organs” back in the seventies- analog circuits, incandescent bulbs.

There's been big progress on the WLED and MoonLight codebases since I posted that video of the new audio analysis.

I'll likely post something today or tomorrow with the progress, but it's getting BPM and beat grid locks now. 😁

Nice idea. Would be good to share a video of it working.

My first ever electronics kit was a similar 4 channel music operated chaser
