Thanks Rob for the TL494 info, and the heads-up on the DDS board.

I've emailed ELV to see if they have an English version of the info pdf and if they'd ship to Canada. This one looks very promising.

Yeh, this is definately a hook. I'd buy 3 right off the bat simply to get 20mhz @ below 150USD ea. for small form factor and portabililty. The output would be to spec and very tight. Very professional.

In relation to my previous post, think in the eye of the hurricain!

God Bless

I think this is a good time to remind people of something SM said.

"I ask you, what are these guys thinking about when they let their
ego's force them to ignore things i have said in the beginning and go off
trying to design and develop their own control devices using SS units.
SS units which are OUTBOARD of the collector ring i might add?
Some of them have gotten results and some of them have gotten big
power surges and dissipation of heat... all of which is wonderful and
certainly proves the point that there is truly something going on here.
BUT, i guarantee you that their SS control devices are all sitting right
beside the collector... aren't they?
They will probably never start the coil and get to catalyst.
I am not saying it is impossible, but it will Damn difficult for these guys to
get more then a big bang once in a while.
And just like me, that big bang will excite them enough to continue for a
while longer.
Maybe one of them will read back and see where I said the SS control
device must be placed inside the collector coil.
then they will explode with, MY GOD, maybe that is the reason why......
and off they will go. in the right direction at least.

God Bless

OK good point Tim. Otto, Roberto and all who have so far tested, did you place your control circuitry inside the loop when you took the data published?

@ giantleap

Otto had his mosfets and drivers in the center and on an aluminum heat sink.  Watching Cam's lab, it did not look like he had anything in the center.  As for Jason, I do no know.

Cheers and God bless,
Bruce  (P.S.  Good quote... LOL) 

@ A few questions on the build.

1) Can anyone show a close-up picture of the mosfets with their connections, or draw a vulgarized diagram of the connections showing which terminals (left, center, right) go where, not in an electronic circuit form but of a visual form, just to make sure everyone is doing the same thing, including and especially me and others who may chose to make this replication. My components are the IRF730 and the IRF840.

2) My rings are made and I have been looking for days for a suitable plastic core to wind the CCs but have not found anything yet.(2 hours again today of running around) Does anyone have any practical ideas. Does anyone know the internal diameter of Otto coils. I want the internal diameter and length to be as close as Otto in order to ensure that the ring is located at the same internal position and the coil has the same depth of winding as I feel this will have a major impact on replicating the performance.

3) Can anyone show a vulgarized diagram of a complete set-up starting at the frequency generator, power supply, make, model and go through the complete circuits, etc. The replication of the frequencies and pulses are critical to replicate this design. Do we need the original equipment settings to replicate this or just supply the frequency (without regard to any amplitude, etc. is ok).

4) Ottos rings are connected directly together inside the rings, while Ronottes' last diagram shows the wires leading out of the rings to a terminal in order to do the connections which is obviously much more convenient for future alterations to the design. but the question is would these extended wires going to and comming from the terminal change the dynamic function of the rings.

You guys, I think someone will have to open some new Otto threads such as;
- Otto's TPU Testing results (one thread per builder/tester)
- Otto's TPU Testing summary (one person can keep track of all tests from all builders, here).
- Otto's TPU theories and comparatives
- Otto's TPU alternative mosfets, drivers and other electronic components
- Otto's TPU alternative overall designs

and keep this thread for building the device. There is getting to be too much other information here that is not directly relevent to building the replication, regardlles of how you personally feel about the device or the many changes we all could make on the design, this thread was supposed to deal with the building OF THIS DESIGN.

Please keep to topic on this thread and make any new thread you feel is required to discuss these other points. Look, this is not to say your discussions are not of interest, but for practical purposes, it would be preferable to discuss such things elsewhere. We all probably have over 100 pages of unposted theories and what we personally feel to be very pertinent observations of both SM's and others designs, including your own works, but this thread is for building and if everyone respects this and moves to newer threads, we could all breath a little better plus the information will be held in more retrievable and pertinent venues.

@cOmster

You may consider opening your own thread and put all your info there so it does not get lost in all these pages.
You could then add to it any other tesing data, you devellop, etc.

Nice vid Cam
Thanks

Marco.
