Mysterious Resonant Circuit

He is driving the base of the transistor negative, not positive.  Look at the polarity of the feedback coil--it is reversed from a normal blocking oscillator.

EMdevices good luck with this.

it certainly seems interesting, i have it running but am using a larger ferrite core, so far i have had trouble in getting a high voltage loaded output.
I have just had to pack up for the night having made a discovery, the type of transistor is critical, first i used a ztx653 but the gain was too low so i swapped to a BC548C this got it oscilating and allowed me to play with cap values, but the break through for me was using both transistors in parralel, i still have a long way to go yet, but not tonigh big electrical storm here

It would be real interesting to know the transistor type you are using and also your cap values if you have a cap meter.

@EM

The miniTPU rides again. Go tonto, go blitzin. lol

I have noticed on many of my tests with other circuits that the load plays an important part in keeping the whole system under compression to then maintain the effect. This touches up on what @armagdn03 was saying about why we are not matching the load to the actual circuit capabilities.

Also, I think the reversed transistor is working because you are actually generating a reverse current on every pulse off which can then pass the transitors diode. Like when we did EC's circuit on the Tesla Project thread showing movement on impluse and movement off impluse creating a reversing current. So you are playing with both the current forward and current backwards. @allcanadian would know much more about this then me.

Good, very good indeed. Keep it up @EM.

good one whatsup

it does flow both ways 

hot and cold.....

ist!

[EMdevices]

transistor:    2N4401,     (from Radio Shack, box of 15)
Base Capacitor:   0.01J    (not sure what that means)
Top capacitor for setting resonance:  47J
Capacitor in LC reactive branch, 220J

I guess there is a naming convention for these, I saw it somewhere once.
