BB Video: Omega Recoil, Mad Electro-Makers Who Craft Giant Tesla coils
(Download / YouTube) Boing Boing Video today peeks inside the electrified world of Omega Recoil, a group of engineers and "makers" who craft giant Tesla Coils, and stage humorous and thrilling performances with those large electrical devices. What's a Tesla Coil? From the Tesla Society website:
[It] is one of Nikola Tesla's most famous inventions -- essentially a high-frequency air-core transformer. It takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage. Voltages can get to be well above 1,000,000 volts and are discharged in the form of electrical arcs. Tesla himself got arcs up to 100,000,000 volts (...) [They] are unique in the fact that they create extremely powerful electrical fields. Large coils have been known to wirelessly light up florescent lights up to 50 feet away, and because of the fact that it is an electric field that goes directly into the light and doesn't use the electrodes, even burned-out florescent lights will glow.
For viewers in San Francisco -- Omega Recoil members will be giving a talk at the 7th anniversary Dorkbot event, which features other cool "maker mutants" we've featured on Boing Boing Video before, like Jon Sarriugarte and the Boiler Bar folks. Organizer Karen Marcelo says,
...and to think this all started because i was bored seven years ago and decided to call Douglas and start the SF one in Marc Powell's garage! Pesco was a speaker at the first one! We had Brian Normanly talk about how to 'liberate' electricity from PG&E. I dont think anyone has the guts to do that now! :) Here's that first event from 2002.More on Jon Sarriugarte's blog.
