I ordered some components to build some accessories for the oscilloscope and had to decide how i would make the PCBs. I decided to go with positive photoresist pcb blanks. So i picked 10 385nm UV LEDs, an Arduino UNO, a 16x2 LCD display with 6 buttons, a super cheap 16 channels PWM shield, a small speaker and a diffuser that i salvaged from a broken laptop and built a simple but useful unit to do the exposure of the PCBs. I had all that parts so the project was defined for what i had available. The box is 3d printed. The box, hardware and sketch are very easy to modify and can be used to other things like UV glue curing, to harden resin 3d printed parts, sterilisation, etc.
