The Tesla Project

There are several things you could do to gain a better understanding of what you are doing.

First go here....   http://www.lautsprechershop.de/tools/index_en.htm?/tools/t_p_schwingkreis_en.htm

Here you have a calculator, where if you have an inductor and a capacitor hooked in parallel. You can change their values and take note of what the natural resonant frequency of those items together are, this is in the yellow box labeled "near infinite impedance at"

If "plucked" your oscillator circuit (inductor and capacitor above) will vibrate at its resonant frequency.

This is good stuff to know!

Another good way to figure your values out would be to place some sort of a non inductive load (bank of lights or something) and adjust component values till you get a max output, use feel and common sense rather than take a thousand readings.

Get something that works well, then take measurements.

Hello to anyone paying attention to this thread
Just wanna add my 2 cents to this...
I am at most a  tinkerer who has too much time at work to browse the Internet trying to teach myself basic electronics. I didn't include any values to the components as I am just trying to get an understanding of how this circuit may be laid out. See what you think.
Thanks,

Thanks for putting up your schematic. I changed my present set-up to try your design but just on the primary side with a cap and diode on the secondary, as I had before and I am sad to say that there is no effect. This is not to say the design is not good or anything like that. It would require more testing with different caps and chokes, but in general, the voltage on the secondary side does not rise at all, whereas in my initial set-up, voltage gradually rises on the secondary side up to 90 volts.

I do notice however on the scope that spikes are created in the primary side but not enough to make any rise in power.

So for now I will revert back to my original set-up and continue working from there.

Son of a gun. I am actually getting shocked. Like a 9 volts battery on the tongue, but simply by holding the two wires that I connect to test primary caps. I am still on the primary side and have not worked out the relay on the secondary side. But I am getting shocks.

My relay coil is probably too big. Erfinders is 141 ohm, mine is 93 ohm. I have a smaller one that is at 160 ohm so I will try it with the same set-up and see if there is any change, since I feel I am not getting enough action from the choke coil and capacitor. It's as if the relay coil should hold back the power and the short should release it. But I can keep a small 12 volt light light off the secondary and the voltage can still rise, so this is an improvement.

Erfinder says try my own values. So I am. The fact that the choke ohms and the primary of the transformer should be in the same range is difficult to find.

The system is very sensitive to the probes of my scope. When I put channel A on a location I can see a certain waveform, but when I put the channel B somewhere else, the A waveform changes. Also, at 10x I can not see much waveform, so at 1x I can, but at 1x the waveforms are to big for my scope screen at the maximum 5 volts div and at 1ms. Crazy.

There are too many things happening to describe so I will just keep up playing with this, integrate the second relay and see what happens.

Here is another clue from patent 568177----

"means for charging the condenser by such circuit and discharging it through the primary of the transformer"

and in patent 568178,page 1-line 40

"and what may be regarded as the local circuits, comprising the high self-induction for charging the condenser and the circuit of low self-induction into which the condenser discharges"

Tesla has stated the condenser discharges into the circuit of low self-induction, the primary -----  only the primary---- as the high self-induction is stated as the charging circuit not the discharging circuit. Tesla said these circuits can be considered interconnected but regarded a "practically distinct", that is the circuit of high self-inductance, circuit of low self-inductance and the secondary transformer.
So many clues 
I just had to edit this in 

Note that the presence of electric current does not detract from the electrostatic forces nor from the sparking, from the corona discharge, or other phenomena. Both phenomena can exist simultaneously in the same system
