Hi there, my name is Mike Tucknott and my mate's name is Dr Brian H Le Page, we've known each other since school (some time ago). Even at that age we got up to dodgy electronics and chemistry (fireworks/smoke bombs/etc).
So, when Brian called me from university about some high voltage stuff called a Tesla coil that he'd come across on the internet that looked cool and dangerous all in one go, we just had to build one...
Over the years Brian and his dad have been great acquirers of junk, so we had a good start with a power supply and caps (we blew the caps to hell).
I wound some coils on 1 ½" pipe, one 18" long and the other 24" long and built a RSG; the motor for this came from a radio controlled model car (read - very slow and no torque). It was a work of art and took me all day to make.
When we fired some juice through it, it worked but only for about 2 seconds at which time the wood burned through and it gave up the ghost (and no output from the coil whatsoever). After reading some more and getting an idea why the thing didn't work we came up with the BM1, which, as the pictures show worked.
All of our coils are known as BM ? etc (Brian and Mike). This is only so we know which one we are talking about on the phone.
In the future should come magnifiers, home built transformers, proper rotory sparkgap and tube coils. I also want to build a Marx generator.
