If you are thinking that this transformer is quite beefy you would be right. Youtube user Photonvids has designed it to be connected to 220V and it has an open circuit secondary voltage of around 4 volts. This means you can safely touch it with your fingers but I would step back if someone was planning to short it out with a crowbar. I guess that might be a good idea if there was no light in the room and you needed the cherry glow of some hot metal to see with. Next upgrade is the copper buss bar since it gets warm during the testing. In some parts of the country they do drug grow house busts based on the large amount of power the grow lights consume, I wonder what the bust team would say if they broke down the door here? No drugs, just the power supply for a time machine…
