Some updates on my experiments. As I posted before the same spark setup same kicks. This time I changed the configuration of the coil to document differences. Currently I am using a ferrite rod about 6ââ,¬Â * Ã,½ââ,¬Å", one end wrapped 6 times with heavy gauge wire and the rest wrapped with finer mag wire. When the spark gap is firing just right not really sparking but hissing, very small gap with magnets very close to the gap, I get 1ma when I diode one side of the secondary an I can light a 9watt florescent light about 50%. When I point the copper wire at an electroscope the leaves separate, only when I point the wire at the electroscope pickup, not if I put the wire beside it. The compass moves back and forth with the pulses not just one way as in a typical electromagnet. When I remove the capacitors there is no effect regardless of how I set the spark gap. When I replace the core with a steel rod same dimensions there is nothing, no voltage nothing. Going back now to the ferrite core I wrapped another rap around the outside of my secondary coil. Get this, there was no increase in the output if I connected the 2 together to form a double rap coil, there was less ma. Also I noticed the second rap on my secondary almost seem to fight with the first rap of the secondary. From there I connected a small separate coil to my milliamp gauge and moved the coil from the edge of the primary to the end of the secondary. Amps were strong at the end closest to the primary and dropped off as I moved to the end of the secondary. I then used the same coil and connected it to my oscilloscope, the volts closet to the primary was 65 on an AC wave, the wave was at +- 2.6MHZ as I moved the coil towards the end of the secondary the volts rose to 110 the frequency remained. Tonight I want to change the secondary windings to a smaller gauge of wire to see what difference this makes. Conclusion: The amps seem to pile up at the primary side and the volts seem to increase latterly or down the length of the secondary. I know what you are thinking ââ,¬Â¦ but overlapping wraps on the secondary produce no better results and I noticed that when the secondary was double wrapped with tape between the layers there was arching between the layers. One more thing my high voltage coil is drawing 200ma but when the gap is just right and the secondary is producing max amps the input drops to about 175 ma.

Hi cOmster,
it is hard to follow, what you are doing, if you post no schematics diagram of your circuit...
How much input power do you feed your circuit, when you can get the 9 Watts fluorescent bulb
to light about half of the full brightness ?
Thanks.

Ok it's nothing fancy. But here is a fast drawing. The part after the HV coil is by Tesla's Specs.

Possible enhancement:  Consider using a power oscillator to replace the rotating cam switch.  It will provide a constant source of switching.  They work quite well into a standard power transformer.  (Or just consider using a small power inverter that goes into a cigarette lighter and use output on your coil and spark gap circuit).

Ah yes I understand what you are saying. I did a lot of testing on that side of the circuit and found that using a cmos to drive the unit could not provide the sudden, violent drop to 0 in voltage. Now if a power oscillator or cmos setup is watched on the oscilloscope at high frequency there is a curve to the on off pulse. Seems no matter what I did, used a 555 timer circuit to drive it or my function generator in combo with a NPN Transistor, I always had a curve in the on off pulse going to the coil, capacitance I know. However using the switch gives a much better pulse with vertical lines and no capacitance. I think Tesla intended this circuit to be driven by a electrostatic generator. Wonder how long it would take me to build an electrostatic generator? I want to try other cores on this setup to see the results. I was surprised the steel rod did nothing. I wonder what copper will do???
