Build Your Own DIY Laser Show: Easy Steps & Amazing Results!

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: https://www.youtube.com/watch?v=HIBH55cbfLM The schematic is here: https://oshwlab.com/chris_9044/laser-show-driver-breadboard You can build this on a breadboard, or you can get it built as a custom PCB.
