[Electroboom] always has some entertaining videos. He recently tried to run his Tesla coil in a vacuum. The video shows some interesting results, along with his usual bleeped out expletives as he drills into his hand and suffers other indignities in the name of electronics.
Unfortunately, a bit of extra bolt caused the coil to arc internally, eventually leading to the impressive device, shuffling off its mortal… um, well, let’s just say its untimely demise. Along the way, though, you get to see some interesting techniques for building a silicon seal for the vacuum chamber, and some neat Tesla coil tricks with a closed off syringe.
We were a little concerned for [Electroboom’s] safety when he calculated the force on his bell jar was about 6,000 pounds. After all, he’s not known for a stellar safety record. However, he surmised that the symmetry of the jar caused most of the force to cancel out. He even tested the theory. Still, if you try this, be sure to be careful. He could have probably stood at least eye protection, just in case.
[Electroboom] isn’t the first person to have put a coil in a vacuum chamber, but he may be the most humorously injured person to attempt it. If the high input voltages worry you, perhaps you can try this variation. Or, if you don’t want to build such a large vacuum chamber, you could do always get small or even go solid state, for the best of both worlds. On the other hand, if you have a coil, there’s a lot of fun you can have with them, without melting it down in a vacuum.
