I did this super similar (ESP32) with a set I got from walmart. Works great!

  I find it amazing to think that your Christmas lights are now way more powerful than my first computer.

    I think about stuff like this a lot, like what technologies I'm (ab)using to do some silly gadget thing.

      Even though it's way more powerful than my first computer, it uses only a fraction of the energy. So yes, in a way maybe you're abusing a pretty powerful computer to do some silly gadget thing, but there's no real negative impact. I know what you mean though. I've only recently gotten into microcontrollers, and because of the time of year I've been thinking of Christmas lights too, and felt the same thing. Then again: I'm also using my M1 Macbook to write a comment on HN, which is only a fraction of what it can do.

        Oh no negativity in the statement, I'm enjoying every second of it!
