Tesla Coil

*cont* They cannot get as big as DRSSTCs can. DRSSTCs are fucking dangerous but cool at the same time. These ones you NEED a faraday suit to touch the arcs or you will die. These things can be HUGE. They are very hard to build because both the primary and secondary coils have to be in resonance with each other. It is a committed build, because it is very expensive to build and even more expensive to buy. Never buy them. Always build them. It's cheaper that way. I spent about 200 dollars total on my SGTC, and for a smaller one online, it costs about 1200 dollars. DRSSTCs cost around 1000 dollars for a big one... to build from scratch. VTTCs are what it says... it has vacuum tubes. Vacuum tubes are archaic transistors. Transistors boost current. VTTCs are slightly more complicated than SSTCs, and their arcs are completely safe to touch. The arcs are still HOT though, but I'm talking electrically. HFSSTCs are high frequency, so they are also safe to touch to an extent. In all of these, I still suggest NOT touching the arcs at all, unless you have a desktop model of an SSTC. Those ones apparently "feel like how a 9V feels like on your tongue." That is the basics on Tesla Coils. Oh and also... Nikola Tesla invented it (DERP no duh). I forgot to mention. They can be over a million volts and various currents, and powered by multiple types of transformers.
