I think this project may have been on my list since I was in high school: rewiring a microwave oven transformer into a potent spot welder. I came up with an Arduino-controlled system that lets me do everything from tacking shim stock together to welding on nuts and studs. This first part is just the assembly and testing. The next part will be a more detailed look at how I machined the parts. I'll upload all of electrical schematics and code up to my Patreon as a freebie!
