HIGH QUALITY TPU DVD Video Released from Jack Durban

i'd bet that's an electrolytic cap there EM probably output filtering.

also, let's not jump to too many conclusions about no active components and self-oscillation etc. not saying it's impossible, just that it hasn't been proven that the tpu works this way. take SM's mumbled "NO" response with a dash of salt re. the battery.

i too spotted the one mosfet there that eldarion did, by the finger. a 9V battery could easily be hidden inside the spool cylinder.

it looks like (can't be 100% sure can we?) this thing uses 1 or 2 mosfets, and a few caps. the choke could be part of an LC or filtering or both. can't do a heck of a lot with 2 mosfets, but an oscillator etc should be no problem.

if those inside vertical wires are only singles, how would they further the quad coil rmf idea i wonder?

It's a spiral of wire,  they seem to be on top as well.  Makes me wonder.

take a look at this zoomed image, notice the spirals.

Speaking of the transistor on top by the fingers, it's tape, I looked at it in slow motion frame by frame, no transistor there, sorry.

EM

P.S.  You really need to see these frames zoomed in an in slow motion, then you can tell the 3D geometry better.

Let me say this one more time,  there are no Mosfets, no transistors, no active components in the FTPU.

When the system "runs with gain" you don't need amplification, pulses or anything, it is SELF OSCILLATING if wired correctly for positive feedback.

EM

Absolutely correct. I don't thing there is anything more sophisticated than a capacitor in this entire device.

I see capacitors, so I agree with you there,  on the toroid, it's one of the wires and some tape I believe,  the other one I'm not sure, but there is a whole lot of tape connecting wires, and the spiral is just that, now there's another interesting feature inside, another spiral, I'll post a picture soon.

EM

P.S.  Ok here it is.  What's it for?  Tunning?  Delay coil?

OK, I'll concede the point, with the provision that there might be one active device, just to get the oscillations started.

That coil could be a battery, but upon close inspection with the video it is reminiscent of a standard EM delay line: http://en.wikipedia.org/wiki/Image:Electricdelayline.jpg

Hmmm....

Sorry, could not resist
