I assumed that he was faking, but maybe not.I can't lie, I laughed like a little girl from beginning to end. That guy is just hopelessly careless. Soldering on a hot circuit just about beats all, insane. I hope he lives long enough to create something amazing!
In the days where I did live circuit development and 'pin 3' biasing of B+ vacuum tube circuits, I was hyper vigilant. Thick rubber soled shoes, rubber gloves, rubber screwdrivers, plastic clips, the whole nine. Being hit with 550 or 600 volts of plate current was not on my to-do list. Plus at the time I lived alone, so it may have a been a week or two before someone discovered the charred, smoking hull of my corpse.
