Hi guys, I made a little key miner that works for keys 66, 67 and 68, using a tiny super mini esp32-c2, it only generates about 24 keys per second but it's a very low power microcontroller, it has an audible alarm to hear when I win the prize, what do you think?

The speed is not great, of course, but it will do for general education.
Well, everyone knows that a tree grows from a small seed.
Good luck with your development.
