Yes guys, that's the one.

I'd like to know what that white stuff is that seems to bridge the gaps between the greyish bumps in between, and IF those bumps are wires, how exactly they (the wires/windings) are wound and oriented.

Thanks.

The white stuff is probably glu.
This was about his first prototype.
I do not know how it was wired but the coil on top looks like a coil similar to a coil placed on the neck of a crt tube.

I am designing the units in autodesk inventor so i can take it to cnc.

thought i would add this observation about the common-mode choke, and the open OTPU.

from some stills i have it sure looks like there are 2 white wires coming from each "stack" in the OTPU. i am calling the two areas that the magnets sit the "stacks", because not only is the magnet stacked on top of whatever is beneath, but whatever lies beneath looks like it might be made from several stacked layers, maybe not. it even looks like there's a shiny pole piece on top of each stack.

so maybe the common-mode choke was convenient to use simply because it has 2 coils on it. maybe the core does not need to be common to both, just like the 2 separate stacks in the OTPU.

i know wattsup feels he found a toroid coil on the OTPU, but i'm not convinced of this.

the 2 white wires sure does indicate that a coil might be located there. is it white line cord like we see as the collector in the TPU15?

its also a possibility that these two stacks are collector coils. the flux from them would be 90 degrees off from the controls, just like in the LTPU and FTPU.

just a flash i had, probably nothing

@ marco i have access to 3 cnc mills .....

real nice ones

should you release your designs pub...   i could have them machined easly....  perhaps we could take some core orders....

for the people that cannot build there own....

just a thought...

ist

if you want to talk you know where im at ....
