Excelent to see someone doing these basic tests.

You should try some Aluminum wire as well. You can get cheap Al wire with an insulating andized coating as "Bonzi wire". See the links I have posted here http://www.overunity.com/index.php/topic,3544.new.html#new

Hi Duff,
very interesting your last scopeshots.

Hmm, I would say, as both of your scope channels
are in parallel just seperated by the 2 switches, that
we have here some kind of  bouncing artifact
with a damped LC circuit.
As the wire is also a very low inductance coil
it would have a damped oscillation with the capacitor.
But now you have to count in the the switch resistances and
the bouncing of the contact points, so
you see these strange pulses.
Maybe you also have a small  arc between the contact points.
so you have a small negative partial resistance, so it is no wonder
the waveform does not look like a damped sine wave, but an amplified
spike.

It would be really interesting to see, how it looks
with a MOSFET switch or a gas filled mechanical tube switch
or a old triode valve.

Many thanks.

Regards, Stefan.

P.S: Duff,
maybe you should also only use 1 toggle switch,
not 2, as this gets you more contact point bouncing...

In your circuit it would also work with just one toggle switch.
