PCB Laminator Is Its Own Project

I did much the same with much the same lol. I used a laminator that looks identical (at least from the outside) and it is sold in Australia as a “Lowell LOOL280”. First up – different toners have different melting points. The toner I was using had a higher that average melting point. Some people have been using the same model without modification and with good results – I assume they have low melting point toner. I replaced the thermostat just like other hackers that were successful but it didn’t work for me. Only partial toner transfer. Then I made a full blown controller with a ATmega328p, opto isolated high voltage switching for the heaters and motor, high voltage zero crossing detector for the micro, 16×2 LCD Display and controls and I used a diode and op-amp for a temperature sensor because I didn’t have anything else lying around. When writing the code – I accidental...
