Joulethief SEC exciter and variants


Here is the coil (in fact, the only decent coil, that Ive made so far), that is in test at the moment:



That coil wire(~0.25mm) is wound around conical pendant cap(cup?). Not sure what it is called in english language. Anyways, the cap, that hides the pendants electrical connections on the upper side.

Approximate coil dimensions:


Lighting the cfl:



The basic circuit, with an additional transistor:




I have no particular reason to use that additional transistor, just a thought, that it might halve the strain, per transistor. Just as using two power resistors in parallel.

That configuration seems to increase the output of the circuit or coil.
Resulting bright cfl, and also a plasma stream, simultaneously, that wasnt the case with one transistor.

At the expense of the transformer(Canon bubblejet 5V/200mA), that gets pretty warm, when testing that t2-schema.

After all, I really like to run this circuit on 5 volts, and will look, if I can purchase some overkill power transistors.

I already have an ancient PC psu, that can deliver 15A/5V.

One might wonder, what is it, that Im after with all this?

Its simply that plasma thing, very new thing to me, and Im looking the way to get the most out of it. Possibly use it in productive, and creative manner.
