power resistor problem

hi arron

i tried on 10 ohm 100 watt, when i turn on circuit resistor will get heated and circuit doesnt trigger

now i am so much frustrated

now I am using your resistor to work

my whole setup is ready

Pranav,

Just try the front side of the circuit without the booster cap in parallel.
Just to keep it simple.

Also, with a reed switch, you have to make sure it is positioned correctly
in relation to the magnet. Take a magnet and hook the reed to an ohm meter
or just put it in series with an led and small battery - you can see that
if the reed isn't positioned correctly, it isn't going to switch no matter how
close the magnet is.

circuit

hi aaron

i am talking about 100 ohm 10 watt resistor what shown in diagram
instead of this resistor i put 10 ohm 100 watt

when i am trying to test this much circuit only,
when i switched it on circuit this resistor getting so much heated

thats the problem i am facing last few days

i didn't change position of reed(commutator) or scr it is same as diagram

i am not using reed switch i am using commutator for switching it will connect
when rotor pass half of the stator

yesterday i brought resistor like you

today i am going to test the circuit

whatever will happened i will get back to you

commutator

hi aaron

this is my motors commutator

Hi Pranav,

That is a heavy duty setup it looks like! Yes your resistor will get hot charging
a cap this way.

Have you seen the lawnmower plasma ignition system Peter and I did? We did
several variations but I'm talking about the one charged with a half bridge.

Another way is possibly with a 12v battery and a 12v to 120v inverter.
Do you have one? There is a risk of blowing the inverter so beware but
let me know if you saw the lawnmower ignition pics. It is identical to the
schematic for the cdi part of the circuit you're testing.

new circuit

hi arron

i find new circuit to generate high voltage

i tried this circuit for just making spark it is sparking very well

what do think is this okay ??????

can you tell me where should i put my commutator in the diagram

and rest of the circuit will remain same as in the circuit diagram

have wonderful day

i don't know that a high frequency pulser will work. a cap simply needs
to be charged and then discharged into the ignition coil. i'd use a minimum
of 4uf as the cdi cap but preferably 10 up to 47uf. perhaps the dimmer
can be used to pulse a power supply to charge a cap?

Here are a couple ignition pics of one variation with the half bridge and
scr.







Do you understand the pics? It is exactly AC through half bridge to cap
and reed triggers scr. And look at geometry of reed in relation to flywheel
where magnet is attached.

If you have mechanical switch, you do not need an scr but you do need
some way to charge the cap.

new circuit

hi aaron

i think this will work properly

instead of relay i am going to use there commutator

what do you think ?????

hi aaron

this is coil

plasma test

Pranav,

I think that will work, I have done that to charge batteries with the plasma
impulses where your 24v battery is but you do not need that to test.
It also could make your battery explode - so for safety - remove for now.

Leave the gap but remove the battery and diode there, you don't need
them.

Relay can work, I have used relays in many of these experiments but little
by little your relay points will fail - you may be able to alleviate that with
snubber cap across the points. But you can try.

After removing the battery/diode, test and it should give you a good
plasma burst at the gap.

The ignition coil provides the HV output and the cdi 16uf capacitor provides
the LV so you don't need the battery to test the effect. The CDI cap and
ignition coil combination already mix both the HV and LV together.

what do you mean by snubber cap ????

With a romp through past discussion on the Gray Technology, I have seen
a different version of the model that I've been using up until now.

Included below is a Zener breakdown charger I thought might be of some
practical use, and the idea of the LV side has been completely changed
in my mind Aaron thanks to your efforts.

I do not claim to fully understand the technology yet, although hopefully
I'm getting somewhere close.
