this is a good tread, but dont forget the basics, first there was a crystal radio, then later a anteena coupler. The german diode which breaks down.

The anteena coupler was the most important of all. also, there was a tunable receiving coil on the coupler, those basics almost always get overlooked. I should point out, the coupler on the anteena connected between anteena and earth ground is isolated from the rest of the circuit.

hey X-blade i´m not completely sure but so far as i remember from a book i read on this the stations are selected in a digital radio by a digital potentiometer that has the off set frequencies at some regular interval... so when we simply change the station the pll will try to lock into the frequency so it can follow it... it follows it by comparing with the frequency output at pin four straight into pin 3 so at pin 14 you get the antena connection..

Hydrocars what this coupler you talk about? i have little knowledge on antenas wish i could know more but I aways want to learn! 

today i was trying to figure out this antena idea...

the only reason i have for it is that i know an antena has high electric fields when its irradiating power and i believe this fields can be what we need to accomplish things like ionization etc..

an antena so far as i understand can irradiate only because of one thing!

thats because its connected to a transmission line that allow the waves to go up on it...

however what is actually happening is that the antena is developing a high voltage at the end... so if we could apply directly high voltage to an antena it should have the same effect?.

not sure because transmission lines although work pretty much like a transformer at 1/4 wave it also creates this transformation by some different means... so its hard to know..

but my best guess is that you can use high voltage to directly transmit over an antena

i´m wrong?

Investigating water properties
« Reply #131 on: August 06, 2018, 11:00:35 am »
I thought of a way to investigate electromagnetic water properties...

i think i could get a 3m water pipe 10 inch diameter and fill it with water...

at one side add a transmitter (source of magnetic or electric fields) and on the other side a coil connected to the oscilloscope...

i guess it will be possible to measure the electromagnetic wave speed thru it! provided there is enough isolation of noise!

inserting a wire inside from end to end is also possible to study the electrical length of it etc...

if course 3 meters is not very long but is something we can work with...

I realized we can use the ac712 as a direct isolated feed back of current or voltage!
of course the cheaper the better... a transformer here is a very small toroid with few turns so dont cost much either

that said i will proably get a couple more for this operation and see the viability..

it could be used between the primary and the diode that goes to the tvs this way it could capture the voltage reversal peak there and send an isolated signal to the lm318 to get right

is the pll phase comparators edge triggered so the point is to detect the voltage spike and compare with the current flow phase...

finishing the pcb design...

i decided to add a safety logic to it so i can simply add a pressure sensor to the cell and let it work to get the max pressure i set up and it stop any signal to the cell

i´m using a nor gate with the gate signal and the pressure signal just before noring the gate signal with the vco just before going into inhibit pin 5

this way if the pressure is high the gate wont be able to turn the circuit on...

I have finished the pcb for the most part

i only used

2x 555 timer
1x lm393
2x lm318
1x 74hct7046
1x tc4420
1x 74hc4066
1x sn74ls02
3x cd4017

3x trim pots

5x potentiometers being 2 a coupled dual potententiometer

1x 4 way switch (pll capacitor and frequency divider ranges) control bandwidth and or frequency range as determined by a two way switch
1x 6way switch (switch capacitors for range in the gate circuit)

here i have all the main circuits

resonant scanning (0,7hz triangle wave from 1,25v to 3,75v)
two pulse indicator circuits (one  for pin 3 comp in and one for the pin 14 sign in of the pll )
gate   (gate freq generator)
pll   ( phase locked loop)
driver (ic for driving the igbt or mosfet directly)
safe logic (system for adding a pressure sensor to stop the gas production at certain pressure predetermined using of course a external reading means for determining the pressure)
lock indicator led (indicates a lock condition for easy to see )
pulse on led (indicates pulse are active )
and the feedback led  (indicates the feedback is receiving signal)

feedback, pulse out, gate ..  bnc outputs
VCO voltage bnc output too
 

for the safe logic i used one of the lm393 amplifier to create a simple comparator such that if the pressure at the sensor signal pass above a certain level it will generate a high signal that will prevent the gate to pass thru the nor gate..

the pressure signal must go also else where on the circuit of control of the injector pulse width for compensating for the pressure... this would allow a better on demand functionality

the missing parts for the complete car are

the digital accelerator that can be a simple potentiometer

the analog voltage generator that generates a voltage signal in correspondence with the rpm to

than in the injector system control the timing for increase the hydrogen input during acceleration and maintaining a lean condition when idling

i guess having a stable hydrogen production and being able to maintain a pressure is the very first step to be able to  test the enhancement of the thermal reaction

after this i can start playing with electron extraction and so on

so Steve how much gas were you using for running that bike?

here is what im working with

the circuit schematic and the pcb

im doing a photographic process at home with photosensitive paint so i had to invert the colors and print a transparent of the the top and down side ... so the pcb will have to be drill hole by hole but there is less holes as possible since that why i chose to use a kind of smd pcb for part of the pins... most of the supply pins 'has holes also valid fo'r components but mostly where the signals had no way to go i changed layer

there are some signal jumpers to allow it to continue or to allow to simply interrupt and let it else where like on the freq dividerts etc

hope you enjoy
