With all that equipment, you could start OU TV or the The Overunity Channel.

I should put up some shots of the lab. Steven would recognize all his gear!  I still have all his DBX, Carver, Yamaha, and Hush systems, and a $hitload of Spheric speakers!

About the pulsing, what if I had a capacitor, an inductor and a zener diode. once the voltage reached a certain level in the capacitor, would the zener open, discharge, then close and start over. Could this be done fast enough. Could the item E above be a Zener Diode instead of a capacitor?

Maybe TRIAC could be used? http://en.wikipedia.org/wiki/TRIAC Sounds like an interesting variant. While it can be triggered with a low current, and then it automatically shut offs. Sorry, I'm just thinking theoretically, but it does look like it can be used for conducting pulse discharge and then work as a protecting diode. From the description it does not react on gate signal when it is triggered - good for "fire and forget" logic. Coupled with a capacitor that provides discharge energy it should work pretty well - close to Otto's MOSFET pulses.

True but it will only shut off during a zero cross and if the unit goes into an unknown state and the gate fails to see the zero cross the TRIAC will remain on.

Well, yes, this info is available there via links, there is also problem with main current raising too fast - so may not be suitable for pulse discharges. I think we are mostly limited in choice by avalanche mode SS components. No other kind of components may "suck" as much current from power source - in theory current may rise to infinity until the unit is destroyed. So, to get high-power pulses it should be whether some mechanical device connected to capacitor battery or avalanche SS component connected in feedback mode (considering DC output) or to a capacitor battery.

Maybe this can be useful: http://www.st.com/stonline/products/literature/an/12244.htm

(from this note it seems that in Otto's experiment the quick oscillation that follows the MOSFET peak is a result of avalanche operation, not something particularly interesting - see figure 13 in the notes for similar oscillation).

      Wattsup look for these things.   A small transformer connected to a capacitor.  This acts to stop the kick energy from going around the tpu again when you don't want it to, and also charges the capacitor.  The time it takes for the capacitor to charge allows the tpu to come back into magnetic resonance with the Earth's magnetic field.  I would say yes your looking at a zener diode.  What happens is this creates a short circuit when it reaches a specific voltage and discharges the capacitor in nanoseconds into the tpu transmitter winding. This circuit is used all the time in high speed voltage regulators.  It is the easiest spike producer to make in the world.  The transformer will most probably be one that is round with 2 wires leading to a capacitor and leads leading to the kick windings.

    SM How long do you figure this will this keep going on before OU's SM tpu board is a ghost town?
