The EV Gray tube is a part of EV Gray's circuit. It's documented in his
US patent 4,661,747 - Efficient electrical conversion switching tube suitable
for inductive loads". My goal is not to duplicate Gray's circuit but rather to
make use of the tube's similarity with other devices with similar geometry such
as the testatika's two pots
(large cans) or that are similarly stimulated with sharp high voltage
spikes such the Hyde Generator.
December 2006 - Testatika Pots with Wimshurst/Spark Gaps 1
June 2009 - Colliding positives circuit tests
This is work is based on a circuit
by Aaron Murakami wherein he got a significant
radiant event within the tube. My goal here is to see if this effect can
be enhanced with changes to the geomerty of the grids as hinted at by the
testatika's pots. I'm
using a Van de Graaff machine to power it to also see if high voltage with
very little current will reproduce the radiant event.
