I've created a very basic laser show driver that will play the standard ILDA files on the ESP32.
We're using a DAC (Digital to Analog Converter) - the MCP4822 over an SPI interface.
For the laser, I've got 5mw red laser diode which we're switching on and off using a MOSFET.
Works really well and gives a pretty impressive show.
There's a great teardown of galvos here: • Inside the Closed Loop Laser Beam Stearing...
The schematic is here:

You can build this on a breadboard, or you can get it built as a custom PCB.
Code is all here:
