Testatika 276mm Disks, 2nd Grids, 1st vinyl disk

The single disk small machine has a black backing and the dual disk small machine and the 3kW machine both have a black rear disk. Could there be a reason for this black material?

Borrowing an idea from Implosion from Holland on the testatika Yahoo! Group I cut up a vinyl record for the back disc with the hope that it would hold a charge, replacing the need for any high voltage power supply. This would therefore give me good oscillations measured across the antenna keys. It worked like a charm! The front disc was the disc with sectors on both sides where each inner sector was made up of two strips of metal and where sectors on both sides were electrically connected and all sectors were electrically connected near the disc axis and where the outer sectors were completely insulated but the inner sectors were not.

After touching everything with a grounded wire to try to bring everything to an equal charge.	After touching the vinyl disc with my fingers to put a charge on the disc. Big difference! And it stays this way for a long time!! The messy output is due to the fact that this is a quickly thrown together hack and the vinyl disc wobbles as it rotates. Some spikes below are 1.5V but I've seen higher since (possibly 3 or 4 volts.) This output represents three rotations.

See also my excellent results with vinyl material with my single disk small machine.

Why the black material? It's known that the disks are first turned by hand and that after a few turns, the disks then turn by themselves. The "something" that taps into an energy source to get excess energy may need the oscillations you see above in order to do the tapping. Once the energy source has been tapped into, that energy may be used to:

• keep the disks rotating,
• charge up some capacitors to continue to provide the charge that the black material provides since it may disipate, and
• be fed into the pots (the two large cans) which convert it to DC, or high frequency pulses DC, or DC with high frequency AC riding on top, all of which would look like straight DC to an analog meter. This is the output.
