Happy New Year 2022 everyone!! I'm back earlier than expected, with part 2 of the DIY soldering station! In this episode we're designing and building the analog controller board allowing us to control the temperature of the soldering iron we built in part 1 of this series, including a quick-preheat feature to get the iron up to operating temperature faster!

Naturally I encountered some hurdles along the way, notably the circuit board not working properly when I first tried it, although given my record working with electronics that was absolutely to be expected, LOL!!

Here's the schematic, it's slightly different than in the video, cuz I had forgotten to include a rather insignificant resistor, as well as the part number of a transistor:
