Safety First... Second and last!!
Sometimes it takes a nasty shock to set you back on track. A rookies mistake which results in a nice 240V shock with 5 Amps being reduced through you really wakes you up in the morning.
So what have we learned?
There is no harm in being over paranoid about safety, so we’ve rebuild some of the original circuits to incorporate fail safe fuses and quick low resistance paths to ground. Like brian said, it’s much easier to replace a fuse than an engineer...
Remember, Team Acid Rain does these experiments, so you don’t have to....
