Lords of the Ring

When i put the fet in the coil it boogers up the effect. Sometimes it stops all togather.  Or like Rosphere's earlier post Momma-Poppa. spikes untill the oscilloations become unstable and stop.

Truning the ring over stops it. I think this has to do with bucking the earth's natural magnetic field. M.M.

....I raise my left hand above the plane of the coil and the light comes on.  Below, off.  Above, on.  Strange.....

Unlike transistors, FETs are voltage controlled so it can be somewhere between conducting and not conducting when you touch the gate. So it acts like a "charge detector".
You can notice/reproduce this without the TPU.

To make the FET not so sensitive to disturbance, add a resistor (like 10kohm) from Gate to Ground. This way static electricity like from human body does not effect to it.
The less the resistance, more power is needed to control but less sensitive it is to disturbance.

Looks like I found this 4.3MHz wave, about 8 volts peak to trough, centered on 15V DC.

The red wire in the photo is the "gate antenna."  It likes to be where it is in the photo or no 4.3MHz.

EDIT: Thank you for the gate resistor tip, Sulake.

Hi guys, after speaking with Ronotte on gn0sis, he pointed out a circuit called a blocking oscillator. I compared the two circuits. The one we came up with, and a few of blocking oscillators, and reading how they work, and explanations of them, It seems that is what we have done here. A mosfet based blocking oscillator. As for the anomalous things we've seen, I'm not so sure. Just that the circuit we have would do the same thing. Here's some more information on them.

I'm not saying that the TPU doesn't use blocking oscillators, just that it's definitely not the whole solution.

Attached is a diagram of a blocking oscillator, and our circuit. I'm sure you will see the similarities.

if this helps i found a self oscillator that is full ban with it is patented so if interested I'll post the web site.       @ sulake - like the resistor trick but will a small peeking cap saddling the resistor increase the transit time ?   also if any one wants the daily schumanns earths hertz rate there is a site that has an appratus that tranmmits to the net daily for the information - free
