I do not understand why people want to make things so complicated.

One 74HC4017 and one OR gate looked simpler to me than several integrated circuits, at least for an initial testing...

One uses a shift register where all stages are clocked synchronously.  Nothing else.

OK, sound advice. Building on the rapid fire rat race controller, one could use a 74AHC164 with a 74VHC27 and 74AHC377 to generate same pulses as with the 4017 but with the nice symmetric delay properties of the 377. Unfortunately, 377 available as SMD only.
[Details: connect Q1..Q6 of the 164 to two NOR gates of the 27, and their output to the 2 data inputs of the 164. This creates a self-initializing shift register that rotates a 2-cycle pulse with a period of 9 cycles. Connect Q0/Q3/Q6 to the third 27 NOR and its output to E of the 377. Then connect Q1/Q4/Q7 to the data inputs of the 377. This yields the output signals for the first 3 coils. The 4th coil signal is connecting E of the 377 to one of its data inputs and the output again to an input, i.e. twice in sequence, to get the pulse delayed/shortened the same as the others. The 164 and the 377 use the same input clock signal.]

For precise timing, one does not use counters and state decoders, nor microcontrollers, nor DSP.

Well, if one does use an embedded controller already, then it looks like an AD9510 clock divider is pretty good. It has 4 identical outputs (twice) that can be programmed to generate the signals for the 4 coils (one divide-by-3 with 33% duty cycle and three divide-by-9 with 11% duty cycle and 0/3/6 cycle phase shifts).

For a clock generator, the AD9912 DDS looks pretty nice, although somewhat expensive (some $70). However, it has some nice properties that make its use convenient: very high frequency output resolution and built-in comparator to generate square wave output. And the interesting part is, it is used by HAM amateur radio operators, so there are already people out there who have some experience with it. While it looks like overkill to have a device designed to generate high quality sine output to then just make it into a square wave signal, it allows very fine frequency adjustments that make it simple and flexible to use (see also AN-823 and AN-837).

Apparently it's better to use an external main clock source like the Epson Toyocom EG-2102CA PECL instead of the internal PLL of above devices. Below are some pictures taken by radio operator DL7IY [dl7iy(at)darc.de] from his article about the AD9912 in FA 3/08 (German magazine Funkamateur).

SM Quote:

- The control wiring is vertically wound in several segments around each of the horizontal collector coils.

spherics made no mention of any horizontal coil other than a toroid (collector) coil (which has vertical windings) centered between the xyz and A coils. He said tao's depiction was correct.

spherics is saying that the collector and control (kicker) coils are reversed comparing his and SM's, and that the kicker coils are bifilar solenoids oriented inward and not part of a toroid config.



Is this thread dead? or am I just way behind everyone else?

Hi everyone, this is my first post, i have just joined as i am also seeking the golden information of the SM TPU, as i want to build one to power my home, but after many days of reading 100s of posts about it on here, it all seems to boil down to coils getting "kicks" at the right phase and frequency, and everyone seems to be talking about making the nessesary frequency generators to drive the coils, i even read somewhere that SM explained that tubes (valves) work best, but one thing i'm still confused about (which i'm sure many of you are too) is that by watching the SM videos of the 3 different sized TPU's in opperation, none of them appear to have electronic control circuitry connected to them! they really look just like self contained toroids, so where are the tubes SM talked about? and where are the 3 frequency generators with the heat sinked mosfets? and the battery supplying them for start up?

I also just read that Steven Mark is ill and has cancer, dose that mean that if he did pass away, that the secret behind this technology will never be revield?

I agree with you Nomen luni
that a lot of this could quite easily be fraudelant claims, and i am skeptikal about it all, but theres this little voice inside me that keeps urging me to look into this deeper, its mainly because i want this to be true, but so much dos'nt add up, like why would SM use a gigsaw to cut a chunk out of the side of his large tpu? he is effectivly destroing a one of a kind, and if it was to proove what its made of, would it not have been better to dimantle it in reverse order? and if it was such a major breakthrough in science in the first place, why is he filming it in a very amature way and with the video being 10 years or so old, it kind of makes me wonder if it is a hoax, but as i said, i want it to be true so im still waiting for positive answers, but if we all have to wait a life time to get these answers, they would be virtually useless for our enjoiment if we are already so old with not much time left, (at least future generations can benefit) but we want answers now.

If OU was really a possability and a prooven fact, why is everything still at experimental levels? should we not be starting to see scematics that work, and kits of parts that build a working product, better still finnished ou generators for sale!

forgive me everyone for sounding negative, but i have only just joined OU.com and have read 100's of pages, but i have yet to see a finnished ou item that works, have i missed it somewhere, is there anyone who has acturally created an OU generator, TPU or otherwise that is prooven to work?

I have bought several reels of magnet wire and magnets in the hope to build my own ou device, this was before i discoverd this site, but now that im here, im more interested in the TPU and i have constructed the coils earlier today, but i kind of lost faith after assembling them and then being stuck as to how to wire them up as SM did his, but i guess thats nothing new to you lot as you are also struggling along just like me, i really hope this is not a hoax, it could be an expensive "all for nothing " project, but i live in hope!

This one shows quite opposite. For 400MHz proton freq it shows  12.951MHz for iron.

This is the problem, there is a lot of differing information on the NMR of Iron itself. the proton frequency of 400 on that site can be changed to reflect a lower value and hence a lower NMR for Fe.

Im still trying to find the exact frequency via other channels.

Some of you probably read this link, some probably didn?t. I read it a long time ago and a couple of days ago again. Something made me to rethink about the control coils. I don?t know who posted it but it is interesting to read, especially one?s thoughts about the control coils.

Kames.

A graph on that link looks exactly like one posted by Feynman.

GO FISH! 

@Gustav,
300V, don't be so silly. Start off at 1V and work your way up.
You need to drive the mosfet with a mosfet driver like the UCC37324 or something with a very fast on/off time and able to handle about 4A or more. You also need some very fast mosfets too with a fast on/off time to avoid heating at the higher frequencies.
Picture here is a mosfet solder to a PCB heatsink and being pulsed at 1MHz. The IC on the board is the driver(not in use).

I use a 30V 3A variable voltage/current bench power supply so I can start low and work my way up.
You need to scope the output across the coil because your back EMF will most likely kill your mosfet if your pulse voltage is too high.

I'm surprised that hardly anyone has built a test rig to try out Spherics idea yet.

I want to put together this circuit soon and give it a try.
