About a year ago my brother and I engaged on a quixotic project to build from scratch a low-cost PCB printer for photoresist. Finally we did it using a Blue Ray™ optical pickup (PHR-803T) and his UV laser/electronics to sensitize Dry-film. The optical pickup is used through his own connector without any modification. We deduced the pinout using reverse engineering and designed a driver for an Arduino UNO to control it. Basically, we can adjust the laser power, turn the laser ...
