HIGH QUALITY TPU DVD Video Released from Jack Durban

Harti,

I still have the circuit but I would have to rewind the coil which is believe it or not the easy part compared to building and troubleshooting the circuit. But like I said I didnt see anything unusual on the inside of the core. If you can think of something that I may have forgot to try that could possible result in something substantial I could rewind the core. I saw a sinewave but when I shorted the pickup coil there was only feeble current. I believe it was less than 50 mA. I used a silicon steel torroid which had a outer diameter of about 7 inches. Each coil was 145 turns and each pair was arranged in a bucking arrangement so that when ther were energized there was a external magnetic field which could be felt if you placed a magnet in the center with one of the coils energized with about 3 amps.

I just reviewed the new tape from Jack again several more times.
At showing the OpenTPU
at 21:19 minutes into the MPEG2 file ( I converted VOB1 and VOB2 to MPEG2 and appended them
via VOB2MPG)
SM says:
Quote:
"Again there is very very little to this device.
Wire is very important..
Coil operation in here..."
And as he says this he points with his finger to a transformer
kind of device below the loudspeaker type connector
and one can see some kind of transfomer with 2 white colored tape windings and
dark grey ferrite or iron cores.
So there is definately a transformer or 2 chokes ontop of each other down there.

This is then probably a simular transformer or 2 choke coils as he uses
in the smaller first device which he presented ontop of his videorecorder equipment.

Too bad I am not at home right now, otherwise I would
just try to pulse 4 control coils via a shiftregister and see
how much DC component voltage I would get at the output coil
and how much current I could draw from it.

Regards, Stefan.

JD,

Thank you for giving us some fresh information. It has been an intense and frustrating ride for the tpu crew everyone loves. I hope you realize all the years that have gone by and some how they are all still here, working on the tpu. I believe, in a sort of spiritual way, that JD's showing up to help us is a congratulations to our fortitude in hanging on over the years. Whatever it is that provided the steps we walk on, I thank you, too.

Chad,
Did you get the field to rotate ?

The OpenTPU does not have any iron or silicon steel in its coils or cores,
only inside the transformer( or chokes) to make the phase shift
between the coils to get a rotational magnet field.

"Where to start .. just my thoughts ...

Looking at many of the good minds and some that a bit excentric ... Beardin, Meyers, Hamel, Bendini, Steven Marks, Dr. Stiffler, Boyce ... and I know that I have missed a few .. there does to be some commenality in all to some degree or related ... I believe in combining them together can get to the picture."

I would move Hans Coler to the top of the list.
