    schematic video

I tried to download it anyway, using the link I was sent when I first bought the videos, but I get an error message. I have no idea what I am supposed to do to get the schematic video. I click on the "order now" on the download page and it wants me to buy the two videos again to get the schematics video.
    Did you get it or not?

      Took me a while to find my password to access the page, but I got it. Thanks! It is awesome! Great Job Aaron! Great Presentation Grant!

        let us all know if there is a possible replication with left over power
        to run a bulb or what have you so we can all get our own package.

        $47 is a good deal for a working OU example.

        Maybe someone who went to the conference can validate.

          Graham's Transformer

          @All, please post any replication attempts here in this thread. Graham is available for support but please try to build it first according to the schematic video where he details the specs of the coils, etc...

          And again, don't worry about all the digital control circuits if you don't have a background in that, you can just use a breadboard to change different caps and resistors in and out manually.

            none

            @BroMikey, Graham stated that the COP is around 1 percent with this particular circuit, but the principle can be applied to other circuits for higher gain.

              parts / progress

              Software to control Numato Labs USB relays similar to what's in Graham's video

              links to executable and source code are in the video description
              The software is written in VB .net for the 8 relay and 16 relay boards.
              The 32 relay board would be ideal because the capacitance and resistance variables could be cycled through the easiest. Just using the 16 board will work though, since the capacitor values are the most wide ranging.

              Elna cores as in Graham's video are here:

                Thank you for this update, I am just now reading this Friday morning.

                I will be watching for replications so i can gain some sort of
                example from somewhere on the planet which seems to be
                very scarce these days. It should prove interesting who will
                lead the way.

                My joule ringer does a good 101 percent also.

                  I've put together an executable with vb.net source code for cycling through two Numato usb relay boards - 16 port or 8 port - (link in the description of the video) so that one can cycle through resistance and capacitance exactly as in the OU video. I'll post another vid when I have the actual resistors and capacitors connected.

                    years back I found a patent that described
                    how to condition a magnetic core. related were orthagonal wound transformers dating way back.

                      frequency

                      was anyone at the conference who knows about what frequency the transformer was running at?

                        apex pa-119

                        these 5mhz, 80v, 5 amp op amps are probably what Graham used;
                        aliexpress.com has the pa119 apex IC for about $57 dollars (cheapest).
