I have some RGB laser light engines made for use in a Microvision Pico Projector from the early 2000's. I developed an analog driver so that the individual lasers can be controlled easily. I also found a Phaser TV remote control on eBay. I ripped the guts out of the phaser and designed a 3D printed bracket the holds the RGB laser module in the right place for the beam to come out of the front. I'm controlling this with a Feather RP2040 coded in MicroPython.
