Kapanadze's TX/RX setup based on Tesla one-wire earth RX?
hi Hoppy and everyone,
Base on attachment you have uploaded without looking at lower half of image at all.
The tesla transmitting and the 1 wire receiver coil looks like the one used for kapanadze."Please do not look at lower half of image it is the one causing confusion"
The only thing i can make sense of Nicola long explanation is the low frequency 10khz to 20khz to be transmitted to Earth.
--------------------------------------------
Base on my 1st experiment using this attached PLL circuit replicated on breadboard up to the inverter output from PLL and i combine with my existing prototype PWM generator stage
(As attached) set at 35% duty for frequency around 17khz.
Using
2 x 0.47uf WIMA capacitors in parallel after 3 turns from toroid/yoke the PLL oscillator automatically tuned to
14.5khz.
Using
1 x 0.47uf WIMA capacitor the PLL oscillator automatically tuned to around 22.5khz.
Take note the circuit diagram is flawed the clock capacitor for PLL pin 6&7 should be
1nf(980pf base on meter).
Pin 11 resistor i am using 39k 5% resistor which i got 38.1k instead of circuit diagram 33k and pin 12 i am using just 100k pot tuned to around 98k to GND to auto lock below 13khz.
For my case applying signal generator for testing and tuning before conducting acutal experiment.The lowest frequency which the PLL oscillator is able to lock is from
12.8khz to around
38khz max.
There is a small trick the 2 output from toroid which produce the moustache waveform may need to be swap after the eg:1N5818 (2xdiodes bidirectional configuration) \else PLL will never auto lock to L/C resonance between capacitor and 25 turns bifilar.
After i have accidentally destroyed my only TLC272 due insufficient supply coupling i am back to LM393 with the pull up resistor for time being on bread board.
This part i am lost on how to explain using PLL to achieve auto L/C lock at 14.5khz i am able to get 214Volts A/C across 60watt bulb at 3.56Amps 30volts.
But using PWM generator to manually set frequency at 14.5khz i merely achieved 172volts A/C at 4.5Amps draw 30volts."Looks like pll does indirectly increase efficiency"
Please do not use diode to bulb at all it reduces efficiency eg:Base on the Ruslan wiring diagram which was uploaded by URFA -Ibrahim months back.

Nanosecond generator
Using 4x 1000volts fast didoes to form full bridge rectifier from the bulb to charge a single 400volts Russian PIO capacitor.The output i think is maxed out at 410volts for 1 capacitor.
This is the part which i spotted in Dally circuit video.There is 1k resistor maybe 1 or 2 watt from capacitor.
I merely connect 1k resistor from positive of PIO which was being charged max at 410volts(exceeded single capacitor at 400volts) to a basic nanosecond generator circuit as shown in attachment.
The negative of PIO is connected to Source Supply negative terminal.
But i am using a special mosfet used for nanosecond generator 1000volts APT10035LLL.
This nanosecond generator have it's own capacitor 0.1uf 2000volts rated which is charged via 1k resistor with just around 30volts drop from 410volts.
If nanosecond generator is powered up via 1k resistor.This does have some positive impact on the output voltage.
The nanosecond generator was pulse at negative half of eg:14.5khz only then i was able to spot a just a small drop in overall current drawn as reflected on my digital watt meter.
Take note the nanosecond generator needs to be tuned for lowest pulse width first then slowly increase until you find that sweet spot.
It does effect the 14.5khz sinewave across capacitor 0.47uf x 2.
At this point i can't 100% conclude if the nanosecond pulse does lower current drawn.Next stage of experiment to connect 2 x Russian PIO capacitors 20uf 400volts rated in series.The 1k resistor is the key to limit current surge to nanosecond generator which normally destroy mosfet at high voltage .
-----------------------------
Since i am living in Asia due to Chinese New Year i did not received my damper diodes yet in order for me to test out my 1.5kv nanosecond generator which is capable of high frequency repetition rate.
I think it's typically 1 or 2 weeks holiday in China/Hong Kong.
