I have been experimenting with transferring voltage over a single wire and powering a low voltage DC load with it.
The circuit high voltage power supply circuit can be found in a link above, along with a description.
The circuit, that I used to power a DC electric motor consists of an Avramenko fork that charges an electrolytic capacitor that powers a crowbar circuit. The crowbar circuit energizes the load when the voltage in the electrolytic capacitor reaches a certain value.
I am not skilled in electronics so I cannot find the values for R1, R2, C1.
I am afraid to burn the Thyristor because I just came up with values that appear to work.
Usually I look for sample circuits within the datasheet, but in this case there are none.
How do I find the appropriate values of R1, R2, C1?
The thyristor I am using in this circuit is NTE5455.

The circuit has to power the DC motor on when the voltage is above 5.1V across the zener diode, than let the voltage grow back to that value and power the DC motor again.
So the motor runs, than it stops, than it runs again.
The resistance across the DC motor is about 70 ohms if measured with a multimeter.
I also header that inductive loads can cause voltage spikes that can burn solid-state devices. Is there any way I can protect the thyristor from that?
When I built the circuit on the breadboard, the 5.1 volt zener diode refused to work as it did with an ordinary lean power supply.
I theorized that if I place two q loops in series with the diodes of the Avramenko fork, I can keep the high frequency, high voltage electricity from pulsing through my circuit and therefore keep the zener diode from not reacting when the breakdown value is reached.
Do you think that this will be effective in solving the problem?
Are there any good neon devices that can take the place of a Zener Diode?
At this point, however the zener circuit does switch the thyristor and the load on when some object is attached to the circuit, that causes the high frequency, high voltage to spark on itself, like a pencil placed a millimeter away from a large metal object, or my hand.
(If this description sounds too esoteric to you, read the entire blog post that I had made, where I describe different strange qualities one-pole electricity by the means of experimentation)
I am a writer and I am unskilled in electronics. I generally avoid solid-state components that are driven by current because I cannot calculate the voltage divider to make them work safely. I cannot read datasheets.
So I need help finding the R1,R2, C1 and I would like you to advise me if the q-loops may be able to solve the problem of high voltage pulsing throughout the DC circuit.
The high voltage penetrates the circuit; maybe because the diodes are not perfect for this circuit, but maybe because it can jump gaps in the conductor that are far longer than those in diode junctions. This high voltage prevents this circuit from being usable for powering ICs and other fine solid-state electronics. They can burn from the pulsing.
Thank you.
