Successful TPU-ECD replication !

@Jason,

at the end you are still here...glad to hear from you.
I mostly agree with what you are saying but.........remember: SM did it almost without any electronics so we are speaking about coils, air and some magnets: that's all. I fear that if we seek the hi-tech way we are going out of the context. I do confirm AS I HAVE ALREADY TESTED IT that using a DC high voltage bias does produce increase in the output (about 4-8%). In my case actually it sufficed a voltage of about 60V...increasing that voltage up to 500V did not produced any more output. I did it just rectifying the ECD output itself and putting it onto an annular aluminum plate fitted under the ECD. Same effect is obtained by just polarizing a secondary winding in the control coils.

I wonder if BB project is successfull as it will be great!  Probably you are building on DDS just to control it. GOOD LUCK!

Hi Roberto,

It has been because of the DDS controller that I have been so quiet lately. I have three very nice TPUs that I can easily test my theories on but so far, the control circuits I have constructed are simply not precise enough to generate the rotating field like I want. But with this new design, which is based on the AD9959 IC, I will have complete control over every aspect of the inputs. I've been working on it for over two months now. When I am finished, I will make it available to purchase so people here will have a high quality set of test equipment to experiment with. Here are the current specs:

Frequency Range: 0.1Hz - 50MHz
Frequency Resolution: 32-bits (0.1Hz)
Phase resolution: 14-bits
Number of output channels: 4
Putput pulse width range: 10 ns to 16.8 ms
Output capacitance driving capability: 20 nF (using UCC37321 drivers).

All channels will be completely programmable from the computer Via the serial port so you can basically do anything with this, from frequency sweeps to phase shifting to various harmonic schemes.

I don't know how much the final cost will be but I will let you all know as I get towards the end of the development. For anyone interested, please PM me as I want to see how much interest there is for something like this.

God Bless,

Hi BEP,

I haven't tried the specific setup you mentioned but in a sense, the two mobius loops on my ECD were essentially a big capacitor since they were electrically isolated from each other other than the point where the load bulb was connected. That was one of the amazing things about the setup, there was no explicit path to ground on the collector, the output was completely isolated from the circuit ground.

But one could still argue that it was just an exotic step-up converter as well. What is remarkable though is the fact that we were not using any iron cored coils to *transfer* the energy. I personally believe that what I saw was excess output, but due to the gross inefficiencies of my controller, it was hardly obvious. That is why I have taken a step back to devote some time to making a good controller circuit. Then I can retest the ECD and my other TPUs to see if I can produce the same effects with a fraction of the input power.

God Bless,

@Jason

When you are ready name your price. I'll find some way to pay for it!

I never put much stock in fancy electronics. Some of my wildest low power results were with 2N2222's 

The fanciest toys I ever had was an old IFR120 and a TBert.

But with that beast? Who knows!

@all

As of tomorrow, due to lack of funds, I will be offline for awhile.

I will be back online when possible, but right now I am stretched too far, too thin, financially. I look forward to conversing with you all at a later date.

Hi BEP,

I will be glad to supply you with one. At the moment, I'm just finishing up the planning stage and will be working on the schematics and PCB layout soon. As for the software, if you or anyone else has any ideas and suggestions for the functionality you would like it to have, please let me know as I haven't started on the software package yet.

God Bless,
