Successful TPU-ECD replication !

@ Otto or Roberto,

Just was looking up specs for the IRF840. I found it has 23 ns rise time.
Then I saw the IRF740 with a rise time of only 10ns !

Is this maybe an even better option because as far as I know the rise time is the most important thing in mosfet choice?

Hello Robert,

I tried the IRF740, IRF630, IRF 510......not good!!!

It is NOT only the rise time, its the capacitance at on and off times of the used MOSFET and of course the resistance of the MOSFET.....maybe I forgot something.

For those wondering about the transformers. The idea of the primary and secondary winding is to have the same mass. If you cannot find the wire gauges that Otto and Roberto have used, I have found a copper conversion table that may help you in deciding the proper lengths to use.

The website is  http://www.calfinewire.com/cutable.htm 

I could not find a table for metric wire sizes but I'm sure theres one out there somewhere.

I also left my calculations in imperial units. That way, I don't have to worry if I use 1" = 22.5mm or 24mm or 25.4mm.

Hello Roberto & Otto,

Could you tell me what the output from mosfet driver that could be good to drive?


I tested TC4428, ran upto 3Mhz, disconnect mosfet(840).  It look like sine wave.....is it OK?

What's about irf7307 singal when disconnect mosfet?   Please...



Best regards,

For the life of me, I cannot understand why you waste all this time and energy being a doubting Thomas when over maybe $20 and a hour of your building time plus time picking up a few pieces of wires & chips from the electronics hardware shop, you will forever relieve youirself of this burden?

You asked so many times what are you looking for in these replications. Otto and others have told you repeatedly at this point in time, SM's TPU videos and Otto's replication videos are similar but not identical. Yes, there both have collectors and controllers but Otto's currently have a PS to intiate oscillators to start the excitation sequences in order to study the relationships between controller interaction with the mobius particle acceleration, so we can close the loop eventually and get rid of the PU . When we get there, whether Otto's is identical to SM's is not the point. Both would have demonstrated exactly the ability to convert aether into reproducible electrical energy which is why we are together in this forum.

Many expert minds are also sceptic but some are helping.  Darren is doing his part in obective reasoning and that is indeed very helpful. Why don't you just DO IT and ascertain validity or just wait on the side line and watch the circus freak show!
