@gyulasun :

Your input is very valuable, always good to see circuits analysed by someone with a profound electrotechnical background.

I have just quickly drawn the circuit also forgetting about more proper timing resitor values.
Your kOhm suggestion for R3 is the way to go to properly limit the current into the diode. Should i limit the voltage across the diode too (with a zener or voltage divider) ? With a 12v supply current, pin 3 would probably carry around 10 Volt to that opto-diode and right now i am not sure if that is too much for the diode.

I have just chained the 3 capacitors going to each coil together in series and with a 4th coil, i am just getting considerate of maybe even attempting to neon pulse the whole thing since this would easily reach the ignition voltage of a neon.

I will try both variants for sure.

Thanks again!

EDIT: 4 coils in action, up to 75 Volt, neon doesnt fire yet, guess i will have to go above 85 volt or so.

@Xenomorph.Your work on this project has been amazing.Keep going your on a roll.
Regarding your idea about neon pulsing,maybe you could add a voltage doubling rectifier.This may take you above the discharge voltage.Regards jonnydavro

Hi,

No need for limiting the 555 output voltage at pin 3 for the opto diode,  yes it is about 10V pulse that drives the diode and peak current is determined by R3, (10V/R3).   (I did not check the timing resistor value... lol  )

Well,  if the goal is finding any extra output, i.e higher than input power,  then I would suggest connecting the output DC voltages of the 4 puffer capacitors in parallel via low voltage drop diodes to enhance current load capacity and build or use a DC-DC converter which receives the parallel outputs and converts them into a 10 or 12V stabilized DC, with ground independence, to replace the presently used main 12V battery.  If such a setup would be able to supply 70-80mA @ 10-12V continuously from (the chopped) 4 (or more?) puffer capacitors then you could loop it back for a self runner setup.  (A good DC-DC converter has a higher than 90% efficiency, so it would not be a big waste.)

When you use a neon for a load then it will draw current above its ON voltage, below it nothing, so most of the stored energy of the capacitors will remain inside them...   I mean what do you learn when a neon is ON in this setup? It cannot show overunity...?

With this 'rambling' I do not wish to get you sidetracked from what you really wish to do, of course.  The bottom line is you reach your goal.

@Gyula:

Would the DC/DC converter beat Lenz law? I mean the timed discharge only affects the magnets motion
during the short time that the cap is connected to the battery.

By low voltage drop diodes, do you mean germanium diodes with 0.3 volt?

I will give it a try for sure. Your suggestion sounds interesting !

Concerning the neon. If i am not mistaken, people have been using neons to send short pulses of energy to batteries due to the fact that at the ignition voltage the neon conducts for a short time while dropping in voltage until the ignition voltage is reached again. I understand that as a simple timed discharge tool.

There is many possibilities here, which is good.

Jonny,

I had the same problem as Bill, I redid the entire coil once and rewired everything twice and still couldn't get it up! Thought it was a size problem .

The coil is again torn down - it was the lidmotor version. I tried AA - 2 AA and a 12 volt source with a voltage regulator. Although the lowest it goes is 3.5 volt.

I guess I got too frustrated and am going to rebuild. Need to wait and see if Bill can get one going.
