Lidmotor - nice ! cool little extra tip there with the foil on the outside of the bulb.
Skywatcher123 - the very thing of using the same gauge was a bit of learning that I didn't
know would work. It does simplify building in a way.
Steve - Good point about the crystal method....will do
As mentioned in the Youtube comments, there is a very strange effect with these. The
input power drops with more capacitively coupled loads. Each item remains at the same
level it was at, until a next load is added and then they all drop in output. Pin can also begin to vary.
Inductive loads don't follow that, they use up most of everything available on small setups.
A small motor can spin well, but will pull the energy down with it.
A receiving coil can have a single diode from 1 wire end, the other goes directly to the
motor and then a 10uF electrolytic across the motor is one way to run it. That always tends
to work better than a FWBR and cap, which again is a bit strange.
The secondary is from a few years back, where I was making an outdoor Wardenclyffe type
of design and the idea was to emulate the thinner connecting part shown in one Patent.
A regular tower on PVC pipe would likely work just the same way, but I like these 2 for
being on solder tubes, similar to Dr. Stiffler's L3's in size and shape. With only 150 turns
per section, it does make me wonder if actual L3's from a SEC would work as the secondary.
Am going to try the posted idea of a tuning cap between the 2 halves, perhaps a variable cap.
News: fellow experimenter and Youtube subscriber iQuest has very generously funded the
acquisition of a genuine fully built SEC 18-1 from Dr. Stiffler.
I do hope that a few others have shown interest in helping him to get the current probe
equipment replaced....even if we're struggling to exactly repeat the experiments shown,
some great little devices have sprung up and, as Lidmotor and Prof Jones have said, the
'old guys' here are a joy to post with.
Some of the table stuff is outside now, where am looking at ground propagation again.
I fail abysmally outdoors but have good success indoors. It hasn't rained in a while though,
so the garden hose may have to be used.
