another small breakthrough on our NERD technology.

This may be a "CLASS ACTION LAWSUIT" with many parties involved, filed in Cape Town, South Africa.

This will have to be done all with "VIDEO" depositions from those involved with the suit ( for court viewing only ) plus experts, in each a field of the libel dispute against you.

I may not know as much about circuits as you guys, but I do know a little about law.  What cause of action might you possibly have?  Also, if you think there is a class action lawsuit involved, you know nothing about class actions.

Fig. 1: The Ainslie multiple mosfet circuit

Fig. 2: My build using IRF830a mosfets, 0.1 ohm shunt resistor (the white rectangular thing) , 0.3 ohm gate resistor (optional), 55 ohm (25 W 120VAC) lamp + small inductor load, 3 ea. 12 V 5 A-H batteries, starting voltage 12.8 V, board front side

Fig. 3: Above, back side

Fig. 4: With the small inductance and my oscilloscope, the oscillations are there but very hard to see. Look closely though and you will see them on the bottom trace in this much expanded view of less than half a cycle. Top trace is input from FG, bottom trace is circuit response (mosfet common drains)

Fig. 5: With more inductance in an external load (the little transformer choke) nice oscillations and spikes begin to show up. Just the mosfet drain trace shown, FG trace omitted for clarity. This is very sensitive to the FG's voltage offset setting.

Fig. 6: Same as above but with a bit of FG offset adjustment.

Fig. 7: Same as above but with scope set at 100 VOLTS PER DIVISION (10 v, with 10x attenuating probe). Note the spikes, they reach nearly to 600 volts.

Fig. 8: A little tweak to the FG and the noise goes away but the big spike can remain.

Fig. 10: Load temperature while running with "cleaned up" signal as in Fig. 8

Fig 11: Showing FG trace and mosfet drain trace. The FG is swinging positive and negative enough to turn the mosfet Q1 and the Q2-Q5 stack alternately, I think, so there are two sets of oscillations, fast and slower. By tweaking the FG these can be varied and moved around.

All these photos were taken within a few minutes of each other. The circuit ran for some time, with that little load transformer well over 230 degrees (F of course, water boils at 212). I was unable to measure any power drawn from the batteries.... they were still at 12.8 volts each after the test.       (Of course I didn't try very hard.... for example I didn't use the Clarke-Hess Power Analyzer, or an integrating digital oscilloscope, or even a battery draw-down test. I just used the Ainslie approved method of measuring the no-load voltage on the batteries-- and using that method, I was unable to detect any drain from the batteries. Duh... what did I expect.... I know what a feriggen lead-acid voltage vs charge graph looks like..... but I realise not everybody, in this Internet age... does. In spite of Google.)

When I am able to properly match the inductance and resistance of the load... and of course when I obtain the rest of the magic IRFPG50 mosfets... perhaps I'll beat Rosemary to the Overunity Prize. After all... it's not her circuit I'm using, is it. Just because it produces the same data... oh, never mind.

Oh... sorry... I forgot to mention the scope settings. Details, details. If I don't put them here though, they'll get lost.

The Interstate F43 FG is set to produce a square wave at 1 kHz, approximately, 50 percent duty cycle, with adjustable amplitude and DC offset.
The horizontal (time) scale of the HP180 oscilloscope is set to 0.2 milliseconds PER scale division for all traces above, except the expanded trace showing the Load 1 (the bulb and small choke) oscillations, which is cranked way shorter, but I didn't record it, sorry.
The "A" channel, the top trace, is monitoring the FG's output directly and is always set to 5 Volts PER division.
The "B" channel is always monitoring the common Mosfet drains, on the coil side of the load, wrt the negative rail. A compensated 10X attenuating probe is used, a Tektronix P6047. The voltage per division on the channel varies from 5 volts for some of the magnified traces to 100 volts per division for the big spike.
The batteries were freshly charged before the demo, and after the end still measured 12.8 volts, no load, using the Simpson DMM.
