Amberley teslathon, June 19th 2004.

This event is traditionally fairly small due to lack of space, but has the advantage of being able to show tesla coils and other high-voltage goodies to the General Public who happen to be visiting  the excellent museum at Amberley, Sussex. The opportunity to scare small children with sparks and bangs can't be a bad thing either....!
Thanks to Nick Field for arranging this event. More pics of the event here. and here.

Adrian Fretwell's coil put in a great performance, filling a large part of the upstairs area with sparks and ozone...

Colin Heath's SSTC gave an interesting variety of streamers.....

(right)..until he pushed it a little too far, with a fairly spectacular BANG as the MOSFETS decided they'd had enough (twice!)

Derek Woodroffe's collection of small coils

(Right) ...but Derek has a little more success...

Undoubtedly the most popular VDG "party trick" was placing a pile of small foil pie-dishes on the VDG and watching the effects of electrostatic repulsion...
Apparently it works even better with Rice Crispies, but takes somewhat more clearing up afterwards....

Part of the museum's marx impulse generator - very impressive to look at, but output was a little disappointing.
