Esp32s are amazing fun. I designed boards in the 80s and I still love tinkering with microcontrollers. The reflux control for my still currently uses a brushed motor controlled by PWM and I am upgrading it to a second hand pump with a brushless motor so I am looking at driving it. I just set up an old drone ESC and am controlling the motor with dshot and it works ok. There is a little pre built board Simple FOC that is also esp32 I just ordered for 20 bucks to give a try.
I've been a developer for 45 years and I still actually like it most days.
I recently learned of ESP32-P4 that has graphics compositing optimizations.
A couple of years ago, I used an RP2040 to build a graphics card with 2D triangle filling and other pretty nice abstractions.
Next time... It'll be the ESP32-P4. Somewhat looking forward to that project, but there are prerequisites that need to be dealt with first. Yes, I'm very grown up. It sucks. :)
