Otto`s replication of Steven Mark`s TPU

[rensseak]

IN FRONT OF YOUR NOSES IS A 5W TPU!!!!!!

There's no doubt of the power cause the bulb is glowing, but the 5W of electrical energy comes straight from the electric company and your paying every electron of it 
Please, let's not try to make them any richer.

Did I just wasted 2.24 merers of expensive copper wire?

can you please also explain why and how if there is no connection to the grid?

Fantastic mate...we have been at this for years..now .because something is wrong with your results..we can all go home..LOL

Seriously.. have a look at Ottos picture then have a look at yours..see any thing different? did you change anything?

Did you apply your great experience and make an even better one?

This is what happens over and over ..its not just you and it is not personal I really do not mean offense..but what happens when we get to the Dangerous stage? which is not far off.

Thanks for sharing your results and picture, it is important to get thru this point..got any twin flex?  is the fet an irf840?

notice any sweet spots? tune very very slowly now..there is a delay .no ?then you could try a few things .direction of wind... I noticed a pot...what 4?

Please try again if you are willing.

Sulake,

I think what Mannix means is the bit you have routed through the coil.  If you look at Otto's picture you will see a pair of stranded wires running through the coil.  Otto wrote, and you can see from his photos, that one of the pair is not connected to anything at all.

I slipped my coil off this wire pair during testing and it seemed to make no difference in my output.

Also, my batteries got very hot and today I find them both down a volt from yesterday.

I tried to replicate it as best as I could.  I have no idea if my replication is any better or worse than yours as I have received no feedback.  If you saw Monty Python's, Life of Brian movie you will remember the two prisoners where one was spat at in the face by the guard and the other prisoner was going on about how lucky he was to be spat at: "You lucky bastard!  You must be the guards pet then.  He never spat in my face!" 

Hang in there, man!

Jason was again our hands last night. Mostly though we just sat, and listened and watched as he worked. He didn't really need any of our suggestions last night.

What he did. (I should probably let this come from the horse's mouth, but no post as of yet)

He built the circuit to the exact specs of ottos suggestions (what we have anyway). IRF840 50 turns magnet wire around a stranded collector. Connections made as per Otto's diagram.

Absolutely nothing. Low voltage, low lumins on bulb, if any. Three sets of eyes watching, everything seemed right. We got the same wave form, which IS an odd wave form, with the spike at the LEADING edge of the wave, that in itself is odd.

We swept the frequencies however, and found nothing of any real interest at specific frequencies. PS would not light the bulb, with or without the circuit. Not sure what we did wrong. A couple of people seem to be absolutely positive that it works, so any suggestions would be helpful. What we would like to know are values for

Frequency
Pulse Width
Power supply settings

Really, we need better documentation.

Experiment failed. Wailing and gnashing of teeth ensued.

So since it was such a short gathering, he decided to play with the circuit a bit since the short experiment was over, and we couldn't get it to work with the information we have presently. he set a cap in series with the bulb, the bulb glowed dimly, and played with the frequency a bit. At around 400khz it got a little bit brighter. About 4w output. However at the PS we noticed more current being drawn. No OU. It did give us a start though for a minute.

Strange thing about all this. At the beginning of the experiment, he tested the bulb at the power supply to see if it would light. No. then we got it to light in the circuit. Took it back out and re tested it at the PS again. AND IT LIT. Whisky Tango Foxtrot?

So he reconnected it in the circuit, and it was actually dimmer than at the PS.

This is with the cap in series however, which does not represent Otto's circuit.

This is all a very brief explanation so I don't write too much and bore people to death.

We need to know more about how this is done.. Better documentation, in order to reproduce the results. I'm sure we'd be willing to give it another go, as it's a simple and quick test.

JDO, or GK, if I made any mistakes in my recount of last nights events feel free to correct me.

Regards all,
Rich

Oh, another quick note, we tried moving the lamp wire coil outside of the 50 turn loop and the bulb lit exactly the same. No apparent difference.

Just a note.
