Reposting my project from /diy/

Some time ago, someone has showed me a kind of gadget/toy that is an essentially a fast changing led strip that you can wave around to create patterns and do light painting. It was ridiculously expensive though, so I have decided with a friend to make on ourselves since it seemed pretty easy to do.
Today I finished second prototype. It uses ESP32 to drive a led strip that allows for an external clock so it can get much faster than typical addressable strip. For now I'm using bitbanging for testing so it's only 150 fps, but with SPI this should allow for much more detailed patterns, especially if you swing it around on a rope.(I think it should support up to 3000 fps IIRC)
The circuit is quite simple, just the esp board, BMS, stabilizer, capacitors and buttons and leds.
The software is in Rust and supports both generated patterns and raw rgb images.

I hope this is right thread.
