In this video, I show my most recent updates for my fully DIY automated reflow hot plate. I replaced the heater plate with a larger one, updated the code and implemented a proportional heater instead of an ON-OFF heater, and added a neon glow lamp to the output terminal of the TRIAC to see when the heater is heating.
