yesterday i went to cambridge to see some tesla coils and various similar things in action at the annual cambridge teslathon. i don't really know much about them and i haven't really seen much of them in action apart from last month when i went to the tesla museum in belgrade on a weekend trip. it was pretty cool but was in a pretty controlled environment. but yesterday i saw this, which i guess was still pretty controlled but a whole lot more incredible to see : http://youtu.be/BP1LuqwX4wk
however, what really did my brain in was this : http://youtu.be/kIWC-MdDpqA
i'm still trying to get my head round it now and sorry if this is old hat to some people, but from chatting to the feller who made it: he plays some music on an mp3 player and this gets fed into a big machine that converts sound into a radio frequency. his home made tesla coil thing is tuned to the same frequency which then causes the arcing lightning as the molecules in the air are burnt.as a result of this the sound is then reproduced in the air due to all the electricity flying about. that's probably the wrong terminology but hopefully you get the gist. i'm probably a bit wrong in my description so if anyone can further enlighten me please go ahead
i really like that all saints song too. this is now my favourite rendition of it
