Sooo … I ditched the logic analyzer and pulled out my scope and … I'm afraid I have to peel off that label again.

Because I don't know if that looks like #WS2812 to you, but it sure doesn't to me. Apparently there's a short pulse, followed by a another pulse that's either short or long. I guess that's the binary encoding.

I'm open to suggestions which #LED protocol that is.

Alt text has some more details and timings.

It is *always* worth searching around to see if someone, somewhere has already done just what you describe - especially after a device goes EOL.

I think we're going to see a lot more citizen-level reverse engineering projects bare fruit, as the #enshittification epidemic spreads like #covid.

We're fed up, and those of us who have the skills and time to do these kinds of projects, *are*.

I know I am.

I just saw a guy #reveng his Phillips electric toothbrush. Another replaced the controller board of an otherwise unusable video router with his own microcontroller and code. Tip of the iceberg.
