Don't measure TPU with digital meter

[sucahyo]

Edit:
post #9 prove that even an analog meter show false result.

This fake TPU of mine generated measureable current on analog but unmeasureable current on digital. I am sure that real TPU will work this way too. Just a prototype concept of TPU using illustration from
otto_ronette_TPU_ECD-V1_0.pdf





Measured around 0.5V at 0.3mA using analog, non existance using digital

Video:
YouTube - TPU can not be measured with digital meter


I would like to know if everyone experience the same thing.

Edit: Touching the wire increase current, and I just realize that the circuit diagram is wrong. I post the correct one soon.

Edit: This is just my own stupidity. The output is AC and as result digital meter do not have chance to measure it. It seems even the AC is biased, indicated by analog.

With diode the reading is 2V 30mA.

digital meter can not measurerectified tpu output current only

Just found out that digital meter still can not measure tpu output current. Which one more correct?

Hi
I saw the same. At my Osc i had no Current or even only 0,6V Spikes,
but it did light a 12V Bulb some bright, not full but like half brightness.

You should allways put a load at the Tpu when you test it,
never let it only run empty, even when its only a small resistor, that is what some do say.

But for this case, i think sometimes, there is still other Current at a circuit,
what they did miss to measure, to show it.

I am still testing different windings like the one from gates or a similar winding,
but SM's Tpu was different.
It was more like with a iron ring at bottom (from speakers?) and one or two
layers over it with smaller Wire.

Thanks . I guess I should try light.

The instability make me rather reluctant to continue. Mine is only a simple proof of concept with only two coil. The input power is about 6 watt. But with capacitor in seris it should be close to zero. And yet it give me this:
- sometimes work, sometimes don't
- only work if I use it in series with capacitor
- only work with my 10000uF 50V capacitor
- do not give output at all when directly powered with radiant.

Either it hate radiant or there is something nullify the result and make it refuse to work. Good news is, all I have to do is to reverse it. Bad news is, I don't know how. How can you reset such simple thing?

Good thing it work when I record it....


BTW, I try to mimic Bob Boyce TPU. But for now I try to experiment using otto's document. I collect Mannix post yesterday from ou which contain all word from Steven Mark:

May insignificant or maybe good news, but this also a bad news for me, my best power transistor pop and die when I connect the donut part to my oscillator. Usually heat up before my transistor dies but not heat is generated. Maybe just my fault for not adding load.

I am guessing the current seen in your first post might be from neighboring RF or stray EMF being picked up by the coil from AC lines. If you have a scope that might tell you a bit more about what you have.

I'm very interested in the TPU and found a video recently from which I captured about a dozen pics of the way it was wound - which I believe may be unique and a bit different than most of what I've seen. I'm not sure as I'm just getting back into this after being out of touch with the TPU for a couple years. But the one I saw appeared to be wound on circular magnets.

Here's some more of the supporting circuit and a couple showing output:
(there was also one more pic showing 0.62 Amps but I had maxxed out how many pics I could upload)

Thanks guys .

I don't have oscilloscope so I won't be progressing anywhere with TPU. However, I found it to be a very good tune up addon for radiant oscillator. I can only think one reason for why my transistor pop, the TPU configuration has somehow increase the electron momentum and add more load to the transistor instead of reverting disruptive charge back to the coil. More charge trying to keep going out of the coil instead of bouncing back.

The transistor never die on other coil even when run in hours using the same circuit and lower impedance coil.

Bob Boyce mention the danger of using strong bias magnetic field. If the magnet does increase input at correct way, we may get uncontrollable condition just like Bob boyce mention. I think high quality component and build is a must for replication.

I think radiant charger utilizing controller coil would have more output power or more efficiency.

I just measure greater collector output by putting the controller coil in series with my radiant oscillator. Input is 12V with current should be lower than 500mA.
YouTube - digital can not measure TPU collector output #3

I hook up radiant current output and collector output to separate HHO cell. The radiant current make the cell produce hho like usual 50mA, the collector coil produce only very little amount of hho, only once in a while, unlike measured in analog meter.


About the circuit, I wonder why they don't have dying transistor problem when they do not utilize the radiant part? I think my circuit conform at least this suggestion:
- very sharp signal, with the help of two transistor, NPN triggered by PNP.
- military spec PCB, since I don't use any.
- I now put the circuit in the center of the coil. I remove the transistor heat sink.

Other I can think for improvement are:
- using battery as power source to produce clean signal.
- Using better transistor for better speed, still PNP triggering NPN configuration

Turn out that there is already compilation of steven mark on OU:
For starters , Read this first, compiled PDF file of Steven Mark postings


Edit: After two hour, the collector part start to put out more HHO output many times it initial. And this is not in resonant in any way.

After three hours the battery standing at 13.35V after rest (14.8V fresh), usually at 13.25. This is a considerable increase for me. The collector coil add another 2 ohm to the original 8 ohm coil, and should reduce the output and yet it produce more...

analog and digital show false voltage

After buying a new solder I finaly able to change the capacitor of my working 555 circuit. I test it on my donut coil today. I found it weird that my donut give out noises when it is an air core coil. Digital and analog meter show <1V value. But I found it later that it should not be true, I got a very good sting. After I got shocked with the output I put neon bulb which then lighted up brightly.....

YouTube - donttrustmeter

I use the donut part (the "control coil" part) of the TPU. This is the circuit that I use:

[sucahyo]

My donut coil is weird. The control coil "BEMF" can make neon produce amber lighting and the primary coil can not....

Hello all,

if youre working on a TPU DONT measure anything in this setup!! Dont even think to connect a scope.....you will blow the scope probe.

For switching Im using 3 oscillators and 3 MOSFETs IRFP 450.
