Easy High Voltage with Ignition Coil and Relay

[@quincey_el]

Excellent; simple, cost-effective. Pay close attention to the close-up shots of his rig; there are subtleties present in the schematic that are not discussed in great detail. Bravo.

[@MasterIvo]

This circuit is ALMOST the same as the Tesla oscillator. the only thing to do is move the capacitor, in series with the primary coil of the step up transformer. The relay most NOT have a diode. The primary is made series resonant with the (tuned) capacitor, and the inductive spike impulses of the auto oscillating relay are fed into the primary. this Tesla circuit can be found in the august 1919 article in the Electric Experimenter.

[@After_Tech_Industries]

Though I do wonder what an auto oscillator relay circuit would need to be at resonance with the primary coil...

[@MasterIvo]

@@After_Tech_Industries the mechanical switching distance and supply voltage needs to be controlled to get the right frequency, which can be a sub harmonic of the primary coil resonant frequency

[@redeye619]

This video has randomly popped up in my feed, this is very handy for a basic arc generator, but this is pulsating DC for AC to be produced the current actually needs to be alternating positive to negative and back, this is just creating a high voltage spike from collapsing and reestablishing magnetic fields

[@Kevin_KC0SHO]

I really like your videos because they take basic principles and apply them in practical and cool ways.

[@Ham549]

Why do you need the capacitor? If you rig the normally closed switch in series with the relay coil when powered on the relay will open cutting power causeing it to close energizeing the relay coil opening it again causeing pulses.

SUPER cool m8 i wasn't sure about this till i saw your vedeo so this is super encouraging thank you for this dude

[@GTagFPV]

Have you ever tried to put the capacitor between the coil of the relay and the ignition coil to the second output? You can drive much more power this way.

[@drstrangelove09]

Can you please give details about the relay and cap cap? Thank you!!!

[@MasterIvo]

the spark can be fed into the ignition coil primary if the primary is made series resonant (low impedance). the impulse (inductive spike from the relay coil when opening) will than be used to amplify the secondary, and will give much higher output! With NO spark at the relay. I will build it and show it on my channel, as this is how N Tesla did it.

Ok. Cool

[@MrCharlieCom]

I've done this using an old fashion doorbell buzzer to make and break the circuit. One good tip is to use the original ignition capacitor in the circuit. The original capacitor will have the correct capacity to match the coil perfectly for maximum high voltage output. Use of other size capacitors will not produce as high a voltage.

[@ludicscience]

+MrCharlieCom Good advice thanks!

[@SUNTZE13]

MrCharlieCom . hi, what is the original ignition capacitor value. thanks

[@MrCharlieCom]

I've played around with these before and it makes a big difference what size capacitor you use. The correct capacitor depends on the particular model ignition coil. About the only way I know of to tell is to find what model car the coil came off of, then look up the part number/specs for what ignition capacitor was on the car. If you went to a junkyard and purchased a used coil, maybe you could have them pull the matching capacitor at the same time. Otherwise, you might try several different capacitor to see which gives the most output.

[@greggrimsley5337]

Ludic Science, I just finished watching your excellent video. I have been searching for this setup. I want to apply this to killing rats in my garden. Do you think it would work? I have built an enclosure with 6 electrodes (3 pairs) spaced 3/4" apart. I want to connect this to those electrodes so when the rat steps on 1 pair of electrodes at the same time it will be killed immediately. I want to use a 12 VDC battery. The only issue might be that the spark will jump to the paired electrodes and continuously fire. I only want this to fire when the rat steps on a pair of electrodes. Maybe I could control the spark gap with a larger capacitor. I would enclose this setup in a water tight non conductive enclosure. Also can you tell me what type 1uf 250V capacitor you are using and what type/size relay are you using and how did you secure the wire in the center of the ignition coil. Sorry for the long response, I hope you can help. TIA

[@bozoloz6078]

I see this as a "basic ciricut" but how much does it draw?

[@THOMASTHESAILOR]

I think that general purpose ignition coil is rated for 25Kv with 12 volts input. That type of single coil was used in all cars and trucks from about 1930 till around 2000. They didn't change much, until 2000, when they went to smaller coil packs, 1 on each cylinder..

[@gregorykusiak5424]

And one per pair of cylinders- a 4cyl will have 2 coils in a pack, and a 6cyl will have 3 coils in a pack. These coilpacks will have 2 secondaries per coil and the system is called a waste spark ignition, because there is a spark present in the cylinder on its power stroke, as well as in the paired cylinder, on its exhaust stroke (of the 4 stroke Otto cycle)

[@alanmcpherson9429]

Alan McPherson Referring to early ignition systems. TO FURTHER CLARIFY...One of the laws of magnetic induction is that the output voltage of the secondary winding is dependant on how quickly the primary field collapses. If you took an auto ignition coil and applied 12 volts AC at 50 cycles the output from the secondary would be surprisingly small, because the rate of the applied current is relatively slowly building up and diminishing at only one fiftieth of a second, but apply an instant 12 volts into the primary, and provide a fast path for the collapsing field current to follow, and enter the capacitor, which quickly sucks up the energy, thus the output will be dramatically increased. Then the points shut, which discharges the capacitor, ready for the next cycle. The points capacitor Is not present in the circuit to stop arcing and damage to the points, it is there to assist in the rapid collapse of the magnetic field quickly soaking up the current from the collapsing field. That it stops arcing and destruction of the points is just a happy coince dance.

Been trying this for a small project but can't get both the coil and the relay to work together with the capacitor.

Any help would be grateful.

yeah sorted it out - didn't use the capacitor afterall and had a continuous spark! Aren't I clever eh? So to get a spark plug to spark continuously all one needs is a power supply, ignition coil, relay and spark plug!

To add a bit to the earlier comment, you need a relay in which there are contacts that are normally closed. You get that with a changeover relay, as shown. It would also work with a 4 pin relay that has normally-closed contacts, but they're probably rare birds. Buy a 5 pin (or greater) one with contact rating of at least 5 amps for this application, I suggest.

Mann that was clear. I've got good understanding of it finally, thanks. Question for everyone.

Will it charge? Less spark being that it's a rechargeable? Would it explode? What if I hook up two? I'm wanting to make a flamethrower kit but not run through all my gas with a modulator. So I figured if I just put an ignition coil not directed to the car battery, it wouldn't kill my battery.

[@lynnwendt9606]

Great video but how do you make the relay switching back and forth continuously ?

[@kjhendrickson]

The relay switches back and forth on its own -- if you connect everything properly. By connecting voltage to the proper pins, the coil in the relay energizes and effectively turns into a magnet. That causes the piece of metal attached to a hinge to be attracted to the magnet. Once the metal piece moves towards the coil/magnet, it causes the circuit to be open (no more voltage) which causes the metal to go back to the original position. So, as long as power is connected correctly the metal will flip back and forth between the coil and the default position all by itself.

[@djwilson48625]

[@eminusipi]

Nice videos, lots of great stuff. I believe that pulsating DC is more accurate than AC. If the coil is connected following the + and distributor coil markings, the HV terminal will produce a negative pulse followed by a few much lower voltage oscillations. It's easier to jump a gap with negative polarity and that's why it is used in automotive applications. I think that if you use this for plasma globes it would be very unpleasant to touch since the frequency is low enough for nerves to respond to the shock. An AC flyback would be better if you can find one.

[@ludicscience]

+eminusipi Thanks! AC flybacks are rare these days, I was thinking on winding my own secondary

[@eminusipi]

Dear TTM, I think you are wrong. If we employ capacitor the gadget will output high frequency, damped oscillated AC- according to the textbooks.

[@AnotherWisenedOne]

@@ferencgal1858 You are wrong. If the AC coming out of the wall is not rectified in the wall transformer, then it will still be 60 Hz AC when it goes to the ignition coil. If the output of the wall transformer is smoothed out DC, then the power going to the ignition coil will be DC, but pulsed at the frequency of the particular relay opening and closing. Some relays will operate or "buzz" faster or slower than other ones due to various factors. Capacitors in the wall transformer housing are used to smooth out the 60 Hz pulses coming past the diodes.
