Stephan
I would leave it. lets see at least till the weekend. He seems to be working hard on it and answering long posts isnt helping.
Id give him a few.

Give Tony a break to concentrate on his work. He has hardly had any sleep while working and responding.
He's been a loyal replier to most of the remarks here.
He deserves some trust and patience.

Stefan,

I made one coil as shown in the images but with 1,2mm copper wire.
I then taped it and put two output coils on the outside. I then taped
the output coils. I use 1,2mm copper wire on the output coils also.
I used my Rosmary Anslie switch to pulse the input coil. Used a 0,25 Ohm
non-inductive resistor on the input coil, after the RA switch. Used a DVM
to measure voltage over resistor. Connected a 15 Watt 230VAC light bulb
to one of the output coils. Measured the voltage over the bulb with DVM.
Used the 0,25 Ohm resistor in series with bulb to find current. Used Ohms
law to calculate Watt in and Watt out.

I think that he has not yet done a proper measurement for input vs. output.
I also think that if he has something that works then he should show it.
I guess we have to wait and see what comes out of this.

Alex.

@darkspeed,

Why the angry face? Just Google 4017 data sheet and download pdf.

Tony made it clear that the primary winding needs to be much thinner that the secondary..

We all want to put our own take on this .I know

Its great you have seen some effect

Please replicate using the  paramaters given

@Mannix,

Did not have any parameters when I made my first coil. I only had the first
text description. Later on he posted information that the primary must be
thin wire. Will follow this story closely.

@ magluvin & groundloop,

anthony said that the pulses were supposed to be very short, probably 10% or even 1% duty cycle would be enough.
With the 4017, using outputs 0, 2 and 4 would give a duty cycle of 1/6, or 16%.
You could put 2 (or more) 4017 in series to reduce the duty cycle more.
Or you could put a small RC network in series with the outputs of the 4017 to generate short pulses at each leading edge.

@ magluvin,
yes I agree it could be woven flat.
We must also know if the secondary wires have to pass exactly right over the crossings of the primary, or if just being in the proximity is enough.
We will also have to find out what effects the form factor has on the performance; Is it better to make it long and narrow, or flat and large in diameter ?

Lots of fun coming up.

@altair,

You could probably spread the output even more on the 4017.

@GL

Thanks for the circuit diagram and the quick work. :) Some comments on it:
1. Those FB diodes will be an overkill for the PSU. Remember there is no flow of holes here, only electrons from the device. This is more a particle accelerator than a transformer. This is where most of you failed in the past watching the results.
2. BC337 cooks, there is a resistor missing in series between the +18V an 0V. Can somebody pls make me a correction with additional resistors and values. My primary winding is 4.75 ohms. Sry for the request but I have many things to document here and the 4017 is messing about.

On your device:
You use HUGE wire for primary. Forget that. I used to fire half a thinner wire with 1500W of IGBTs, not BC337... :)

Please make a comparison, look at my corrected design for the new BC337 circuit you made:

More photos later on the separate primary winding.

@Stefan

1. I opened the topic because you requested me to start sharing ASAP if the 1W is correct.
2. I did and now I want to make sure what you will receive is not kilos of SM-like overheating demo tool + huge heatsinks, fans, starting caps, inductor piles but a reliable lightweight swiss watch that you can take to presentations with yourself and you'll not curse my name.
3. I wasn't prepared for crowd with ready to build schematics and competition run they urged me. If I know this I wouldn't come out yet until your device is done.
4. My health doesn't serve well and I agreed with you to disclose ASAP. I want to make sure if something goes wrong with me this thing will survive.
5. I am not looking to win the price or anger anybody. I can disclose it elsewhere if it doesn't work here.

So again to all, pls everybody, patient. Not a competition.

hi all replicators,
to avoid the minute delay re 4017 resetting simply use 3 of em in a chain and get the output pulses from the carry out pin. if it is neccessary for total precision timing.

Yes it is true but that was just a comment on the importance of the duty cycle. It works with 10% on all my designs, however that is the lowest edge.

The duty cycle makes difference when finally you want to lower and control the output current on the secondary to keep the voltage nearly constant. The best preformance ratio used to come on the 50% duty cycle.

Tony,

I did not know better at the point of coil making, so that is why the HUGE wires. LOL

Do you need one current limiting resistor at each transistor or do you need just one
resistor from the common plus point to the three coils?

Tony,

try high side switching!
