By building the LTPU from SMs videos with out any frequency specifications except 5khz, square waves, Ring diameter of 17 inches, Radio shack parts, the white HV discharges, the amp meter in the center as a guide I have been able to configure this device in a myriad of ways to research any whim of connections. A remark was made about building this without the specific parameters but I have what they don't, a radio spreadsheet.
I tested the outer ring as an open antenna and found a resonant Freq at 3.2Mhz. I also tanked it which allows for a bandwidth to play in. By using audio equipment I have found a toroidal field of 12 feet in diameter. I havent moved the audio equip any further away but I am sure the field is out there even larger. I am very pleased with this. I have built different types of center toroids for testing and they all receive, 'just like a radio'. And why not. With the latest center test rig I then tuned the centers to the ring res freq. This too proved eventful. The idea was to raise more questions because of the lack of technical specs by SM. I tuned everything using sine waves then switched to squares. Back and forth. The latest result is the effort to grab a certain freq from within the square wave harmonics. Just curious.
Then main idea is to cause a oscillation of an EMP on the top and bottom horizontals 180 degrees out of sync to achieve the thumping. Sm mentioned the HV on an open cable causing the ends to jump. He gave away so much. This might not encompass all the constituent parts being tuned to the same frequency of the outer ring but so far its all we have to work with.
I am incorporating a homebrew charge pump to include one side of a toroid of the centers to facilitate the timed EMP like the signal picture shows.
