"Tuna Can" Rodin Coil With A Joule Thief

In this video I demonstrate the "Tuna Can" Rodin Coil with the standard Joule Thief circuit. I see an odd "fuzzy" anomaly with this coil at the start of each cycle. I'm not sure what that is. It doesn't occur when I switch to a 9V battery.

Did you measure the voltage of the nine volt battery when at high current and at low, 65ma, current? These batteries have a small AHr rating and drop in voltage quickly when load approaches 1/2 C rating.

Good suggestion. Next time I will be more careful to start from a fully charged battery. It may have had a weak charge on it which could explain the rapid current drop. I thought it was charged, but I did not check that carefully.

I was looking over "Magnetic Amplifiers, another lost technology" by George Trinkaus and see that the "Tuna Can" Rodin coil may be acting like a "saturable reactor". The magnetic flux will influence the permeability and thus influence the current flow.

I've gotten to the bottom of the fuzziness. If the clip-lead that is attached to the negative of the battery is brought in close to the coil, or laid around it, the fuzziness intensifies.

@morpher44 If my conjecture is correct, then when you bring the negative terminal (which accumulates positrons) into proximity of the coil, it is having some type of repulsive effect on the giant positron in the center of the toroid, or perhaps the positron motion which constitutes the direction of the current, which you know flows opposite to electron flow.

The Joule Thief oscillator is exploiting positive feedback by inverting the signal twice, once thru the transistor ... and a 2nd time thru the transformer. With a Tuna Rodin Coil as the transformer, the geometry is a bit different in that the inductive energy transfer between the two coil circuits is in this unusual toroidal - cylinder - god's eye -- shape. The magnetic fields are nicely zinging around the cylinder.

@morpher44 I've been researching the rodin coil and all forms of vortex - natural and manmade - very intensely. What I've concluded is of some importance, it basically involves the vortex wound coil creating a giant virtual particle in the center of the toroid. This virtual particle is essentially the positive magnetic monopole, a positron. The same positron is created between the opposing poles of any magnet, and constitute the force of the repulsion.

I love this tuna can coil!! LOL! Nice work man.
