To build a coil gun, all you need are a few tools, some wire, and a disposable camera. Electrical oscillation and resonant air-core transformer circuits had been explored before Tesla. Modern transistor or vacuum tube Tesla coils do not use a primary spark gap. July 2005; DOI: 10.1109/PPC.2005.300508. Join today and be a part of the quest to understand the enigma of Nikola Tesla. We have you covered. = Experiments have shown that neither circuit offers any marked performance advantage over the other. (1) Closed-core transformers used at low frequencies, (2–7) rearranging windings for lower losses, (8) removed iron core, (9) partial core, (10–11) final conical Tesla transformer, (12–13) Tesla coil circuits, Typical circuit configuration. His Tesla gun, inspired by graphic novel The Five Fists of Science, is essentially a hand-held spark gap Tesla coil powered by an 18V drill battery. W a nice stream of argon would do as well. 2 However this does not mean the current is harmless. I get about a half hour of continuous running on one of these: http://j.mp/K44237. Great work man! Welcome to the Tesla Coil Design, Construction and Operation Guide. The aluminum is actually a safety feature for the user. For any non-believers, Flickenger also uploaded a video of the spark shooter in action. The current passes from the metal into the person's hand through a wide enough surface area to avoid causing burns. Modern high-voltage enthusiasts usually build Tesla coils similar to some of Tesla's "later" 2-coil air-core designs. The oscillating currents in the primary and secondary gradually die out ("ring down") due to energy dissipated as heat in the spark gap and resistance of the coil. http://j.mp/JreFOW, You are correct on the size: it is listed as 2″ (ID) but I care more about the size of the coil wrapped around it (2.5″ OD). A large Tesla coil of more modern design often operates at very high peak power levels, up to many megawatts (millions of watts, equivalent to hundreds of thousands of horsepower). The kicker here is, this coil is NOT running at 20kV. For coolness factor, you can probably do away with the torus. Get more GeekTech: Twitter - Facebook - RSS | Tip us off | Follow Elizabeth Fish. After air drying for a couple of days, I fired them in the kiln at Metrix, let them cool for another day, and… Ta da!
