user TURBO?s replication of Steven Mark?s TPU ?

[Mannix]

X is right!

I doubt that there will ever be words that will convince any body that has not built a tpu and had a go at mixing these frequencies.
however if ...or when words become available they will only be understood by those who have built a few coils and experimented a bit.

The guys that have posted videos are a bit cheecky i think but at least they are doing something. they have told you that its not a marks tpu its just something to stir up the inspiration...Funny how some of the doubters suddenly changed their tune.
I dont agree with what they did but I certainly respect most everything else that they have done...

It could be a long road

It will not be easy to build ..thats for sure ...but make a start..

There may be help with along the way......

I've just seen the videos of the TPU.rar file, I ask my self about the power involved to light the bulb, do we have any idea of the ouput power of the device ... because when a 40 Watt (or 60 W)bulb is switch on you can not keep it in your hand for even 1 second it is to hot.

Did you read what I posted?  I have not claimed to have a fully working TPU.  The videos show a lighted bulb, that doesnt mean free energy.

You have been given you what need to start for yourself, stop questioning the videos.  Are you looking for proof or are you looking to build your own and discover the secret.  I urge everyone to get winding and start testing, forget the videos please.

The key is mixing 3 frequencys, you HAVE THE ANSWER, USE IT!

Hi Dave,
With the pulse circuit in your PDF that uses the ICL8038:
http://www.intersil.com/data/FN/FN2864.pdf

You are using the pulse/square wave output so that you can control the duty cycle as well as the frequency.

At the moment I am building a push-pull circuit based on the TL494CN (for the MEG).
I see that you have used a single timing capacitor and two pots for the range selection (course and fine).

Did you consider using a rotary switch, say 12Way single pole and a series of capacitors to give you 12 overlapping frequecies?

The ranges could go from 8Hz to 350Khz in steps that are ~ x 2.4 each start frequency.
ie.

1. 8Hz - 20Hz
2. 20Hz - 50Hz
3. 50Hz - 120Hz
4. 120Hz - 280Hz
5. 280Hz - 670Hz
6. 670Hz - 2KHz
7. 2KHz - 4.8Khz
8. 4.8Khz - 11Khz
9. 11Khz - 26Khz
10. 26Khz - 62Khz
11. 62Khz - 148Khz
12. 148Khz - 355Khz

It may be possible to do away with some the lower frequencies but you never know.
Are you UK based?

I have started a circuit layout using Eagle PCB design tool for the TL494 and I could do one for the ICL8038 if anyone is interested.
If you keep the board size below 4"x 4" you can use it in evaluation mode.

Regards

Rob

Perhaps I miss someting beacuse i've just read all the 19 sheets, then more clearly it is not against you,  the question is about the ratio
(power out / power in) that's all. Even if it is not ou it could worth to build if the ratio is 90%, then do you have measure it that's all I ask.
