Over the last few months I've been building a Tesla Coil from kit from a company called OneTesla in the US.
I haven't soldered for years and this may have been why the original board failed to spark into life as it should have done... So after a wait for the board to clear customs and yet more ridiculous customs charges the new kit finally arrived. It certainly kept me occupied whilst I was in recovery mode from the knighthood attempt the day before...

So, what an earth does this contraption do then? Check this out... :-)
Beat it - Michael Jackson
Scary Monsters and Nice Sprites
Mortal Kombat theme tune
The Tesla coil changes the voltage to around 250,000V which creates a plasma at the discharge tip - this super heated gas rapidly expands away creating a pressure wave which we hear as sound. By modulating the input current we can tune the output - essentially creating lightning that plays a tune. How awesome is that?!!
Update: got new software tonight which has made a big difference - the coil is no longer missing notes and is really living up to its potential (pardoning the physics pun)...
Check out ACDC's Thunderstruck - can't think of a more apt tune to demo!
