Wanted to let you know Facebook people are stealing your design or whatever; making them like 0.27-0.47f capcitors at either 35/50v. The design was super impressive enough for me to review this circuit. I will build the circuit based on your work and report back within a year. Or someone can do that.

Power supply was the question but seeing that you had the portable spot welder using 18650 cel, the Facebook revised it to either 5 volt or 12 volt power supply and the result of solder was visibly harder to rip the tab off the battery cell. Hoping this will help all of us here too.

Your capacitor calls for 2.7v at 1 farad.
