Bob,

I have a few more questions for you, if you don't mind

1.) Have you ever observed a cooling effect in the coil or does it always run hot?  I was wondering if the coil may actually be utilizing some thermal energy from the environment...just a shot in the dark.
2.) Is it OK to put a capacitor across each of the primaries when driven in single-ended mode, in order to "force" a resonance at a lower frequency?  Or will this not work with the longitudinal energy?  Just wondering, as I found that the primary coil resonance is very weak with the small capacitance in my test coils.
3.) I noticed that someone deleted the posts on OUPower.com related to the TPU.  I personally found those very helpful as a way to realign my thinking every time I go off on a "conventional electronics" thought path.  Is there any way you might be able to re-post them here?  They also seemed to sum up the basics of the energy converter nicely.

Thank you!

You can tune it to run cool, or you can tune it to run hot, if you use the right kind of core and wire. If you use the wrong kind of core and/or wire, it can run hot from excess eddy current even if you try to tune for otherwise.

A capacitor across the core will shunt and waste energy. Capacitors are not usually very efficient at high frequencies. The TPS does not scale down very well, as the really high frequencies smaller units would require should be totally avoided if you value your health.

Those posts from oupower are lost and gone. I did not save them anywhere.

The new HexController+ Deluxe board arrived today. I installed the surface mount caps first before I paint the board. Boy are those 330 pf SMT caps tiny ;-)

That is great news Mark. Keep up the research, there is still more to discover. You can find 100X or more ;-)

Sprayed the PCB with Testors #1601 to protect it. After it dried well enough to handle, I started mounting parts.

I ran out of a few parts in my parts bins, will have to place an order.

I was able to power-test the board prior to inserting the ICs. Everything checked out OK up to this point.
