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.
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 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
Looking at your schematic, I see that when the normally closed relay contact opens, the capacitor, whose purpose is to "ring" the primary of the ignition coil and to supress arcing across the relay contacts is disconnected from the spark coil. The correct position for the capacitor is in parallel with the spark coil primary, forming an undamped resonant LC circuit. This would produce a much fatter spark at the coil secondary. With the capacitor connected across the NC relay contacts, it does protect them, but any ringing of the coil will be prevented since the power supply will be in series with the LC circuit, overdamping it. Also, you might need to experiment with the capacitor value to get the best results. I'd begin with about 10uF.
The capacitor just dampens the arcing across the contacts sponging excessive voltage so increasing the size would be a waste of resources not changing it a noticeable amount but to small will fry the cap causing a failure in the circuit.
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
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.
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.
@@ludicscience hello sir can it work with a electronic resin ignition coil? with a electronic distributor system? just making sure and how many amps does the relay need? set up on a lancer sl 1985 production
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.
Thanks for great video, watched last night , put it together today, works like a champ. helped me find a leaking high voltage shielded wire. Many thanks!
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.
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..
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)
Now that is fun, check the voltage on the primary with it running, it will be in the 100's of volts as the field collapses. I remember trying to attach a dwell / tachometer to a coil while the engine was running and did not think there would be a shock hazard. There IS
Ludic Science ...I Really Love your posts, BUT can you Comment about my Coil Driver Issue. My Relays Continue to Burn up or Jam ..Im thinking the Relay is Cycling to fast ?? Im using a Quality Relay ...is there a way to Slow the Switching ??
Very good. If you do this, just make sure the capacitor has a satisfactory DV/DT function. A common radio etc. capacitor will not cope for long. Try one out of a distributor or magneto.
Here you have the basis of a tesla coil or a Spark gap transmitter, This was one of the first types of RF broadcast transmitters for long range low frequency broadband transmitting. Pretty much outlawed these days as they were very RF dirty, disrupting a broad range of frequency's across the RF spectrum.
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.
+Ludic Science I think that the challenge would be finding the right ferrite core to accommodate the HV winding. I haven't looked lately but some of those old flybacks may be available on ebay. Good luck.
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.
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.
quite a few years ago. I tried to connect primary of this ignition coil to MOT (2100V ) ...you can imagine what happened....no..it ditn't make any sparks..it EXPLODED to my face and all over the kitchen ... :D :D god...
Mann that was clear. I've got good understanding of it finally, thanks. Question for everyone. I need to know if I hook up an ignition coil to a 9v square battery and solder in a capacitor, will it give me more spark than without the capacitor? If so, What if the 9v is a rechargeable? 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. And I have the free will of just pressing the flick switch when I'm at high rpm(when I know my car's gonna spit fuel ) Any theories? suggestions?
Some videos show they use a turn signal unit that's made for cars in place of the 555 timer. Look them up. Look for "homemade DIY fence charger." OR with this same circuit change out the timing components (resistor / capacitor) values on a NE555 timer IC. Wire in an LED light for the timing.
I just now found the video you need to make your circuit. ruclips.net/video/leKNbhFfE-Y/видео.html The video linked above is made by the same person who made this video right here.
@@tunahankaratay1523 No, he meant an automotive relay (Typically capable of 40A, and the nominal coil voltage is 12V), and a microwave capacitor (really big. Probably close to the size of the ignition coil in the video).
The relay was nicely oscillating until I connected the coil primary and it stopped. Then I tried to use larger 18v battery it worked for awhile but then burnt the relay
I just tried to build this circuit using a matched automotive condenser/capacitor but my automotive relay is just buzzing. Is the oscillation too fast for standard relays to be able to actuate? Did you use a reed relay? The one in the video doesn't look like a reed relay either. Any advice would be greatly appreciated!

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
I am working on a Induction Coil with a mechanical interrupter, but I cant seem to get it to work properly, so I wondered if you think that this driver can replace the interrupter?
Make sure all your wire connections are as short as possible or like me you will find out it wont work. Solder all connections I am a happy camper now, Works great!
@@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. Randy
Ludic sir after passing current on if we remove the HV wire piece where does the current jumps inside coil or it doesn’t jumps any place unless meet negative ?
Been trying this for a small project but can't get both the coil and the relay to work together with the capacitor. I have connected a spark plug to the coil and can spark the spark plug once using a 9v battery without the relay and I can get the relay to continuously oscillate without the coil connected but having problems combining the two set ups so the spark plug continually sparks intermittently. 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!
When i connect relay to ignition coil it stops buzzing. I think its because of low current(1amp adapter). Relay's coil got 400k ohm, indiction coil got 0.6 ohm. Can increasing amper output help? Or adding some resistor on way to indiction coil make it work?
Great video. I need to build an electric fence to keep deer out of my grape vines. Last year they ate every one of them before they got ripe. Would this work for a wire about 100 feet?
I don't understand that nobody shows this high voltage design since it is so simple, cheap and you can't as easily go wrong with the voltage or amperage as by using a transistor.
The now shut down website of S1R9A9M9 told of certain obscure tests done , as related to the triple coils assembly , as used on the 18HP Briggs engine from riding mower that ran on mineral water in carburetor 2008. A high voltage pulse through high voltage cable that is wrapped in 60 turns of insulated hook up wire and steel nail core, with 20 amp draw from 12v battery and .6 load resistance - will change to 12Amp draw as reactance in .4 ohms is CREATED in the 60 turns.
Mr ,if we change capasitor with other thing (non capacitor) Such as dioda or transistor or 12 volt small lamp ,what Would it be to ignation coil ?, is it work or not.thank you ,
Can you put you write out the number schematic connections instead of the picture? The picture is good, but doesn't call out the numbers. I've tried this is a 4 plug relay. It seems this setup needs a 5 plug relay to work. Please elaborate a bit. Thank you!
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.
how much current in the output? is the spark would still fire if two cable are submerge in water? is the coil can operate like that for a long time like 2 to 4 hours? i want to use it to make high voltage colloidal silver.
i have 2 questions with regards to your device ? 1) what size cap are you using and or can you interchange as you see fit ? 2) can i use a normal 12vdc 5 pin relay thanks

Hi! Thank you for this excelent video. I want to use a TV Flyback as a ignition coil in a experimental motorcycle do you think it will work?
Why? TV Flybacks have very brittle ferrite cores. Putting that next to vibration nightmare is not a good idea.
Been trying this for a small project but can't get both the coil and the relay to work together with the capacitor. I have connected a spark plug to the coil and can spark the spark plug once using a 9v battery without the relay and I can get the relay to continuously oscillate without the coil connected but having problems combining the two set ups so the spark plug continually sparks intermittently. 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!
Thanks
We wish you success

When i connect relay to ignition coil it stops buzzing. I think its because of low current(1amp adapter). Relay's coil got 400k ohm, indiction coil got 0.6 ohm. Can increasing amper output help? Or adding some resistor on way to indiction coil make it work?
It would be nice if you would to make tutorials on high voltage probe for dc, ac and pulse current. :o)
Is the capacitor ceramic? Can you use an electrolytic? I have a school project and are quite new to electronics. Thanks, pls respond i need help!
Never electrolytic
Sir I wired a auto relay both hots and grounds together it definitely occilated so would installing a variable capacitor charge the frequency?
Great video. I need to build an electric fence to keep deer out of my grape vines. Last year they ate every one of them before they got ripe. Would this work for a wire about 100 feet?
I don't understand that nobody shows this high voltage design since it is so simple, cheap and you can't as easily go wrong with the voltage or amperage as by using a transistor.
Hey is it ok to use bigger capacitors? like 220uF for example.
May i know what is the relay current rating
by any chance can this relay oscillator drive a tesla coil from 240VDC the same way it does with the ignition coil?
What happen to a person that accidentally touch the output of ignition coil when it's alive? Just asking,. Ty for response

hello, what transformer is the one in the video? I don't know English very well ... I would like to know the name of the electrical transformer.
made it work my coil was bad, bought a new one and worked, can it work with a solid state relay ?
The now shut down website of S1R9A9M9 told of certain obscure tests done , as related to the triple coils assembly , as used on the 18HP Briggs engine from riding mower that ran on mineral water in carburetor 2008. A high voltage pulse through high voltage cable that is wrapped in 60 turns of insulated hook up wire and steel nail core, with 20 amp draw from 12v battery and .6 load resistance - will change to 12Amp draw as reactance in .4 ohms is CREATED in the 60 turns.
Can you give the list of specific materials that you use to build this thing..
Can we use it for electrofishing..?
My Friend, The RELAY your using is What ?? 12V 5pin ??
is this coil a truck's part or an old model's ? coz cars have much thin ones

What is life expetance of that relay?
I've got 4 pins 30,85,86,87 now which wire connect to power ,to ground ,to capacitor, and coil high voltage,?
Mr ,if we change capasitor with other thing (non capacitor) Such as dioda or transistor or 12 volt small lamp ,what Would it be to ignation coil ?, is it work or not.thank you ,
this is 12v relay right?
+tyrese trimmingham right
Is this a hot spark?
I mean, would it burn a piece of paper easily of you held it in between?
Very easily
ah nice thats what i need.
I took apart a gas-light and tried using the sparks that heat up the gas, but it didn't work at all...
Can you put you write out the number schematic connections instead of the picture? The picture is good, but doesn't call out the numbers. I've tried this is a 4 plug relay. It seems this setup needs a 5 plug relay to work. Please elaborate a bit. Thank you!
+Mckane Buller Lee Yes it needs a 5 pin relay
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.
can i use this to catch a fish?
Very nice! Thank you!
+Lorgio Pieper Glad you like it
Super simple.
Can I use this step up in car's engine....does it affects the car engine in any way.....
how much current in the output? is the spark would still fire if two cable are submerge in water? is the coil can operate like that for a long time like 2 to 4 hours? i want to use it to make high voltage colloidal silver.
current is around 5 ma. if water is distilled i think it may work. howwever i don't think it can be used for more than a few minutes
cant you use a diode for arc suppression for the relay?
i have 2 questions with regards to your device ?
1) what size cap are you using and or can you interchange as you see fit ?
2) can i use a normal 12vdc 5 pin relay
thanks
+Nico Botha you can use a cap from 0.5 to 2 uF, ceramic or film type. Yes you can but it has to be 10 amps or more
Ok thanks ! It works. Do you have a video on how to connect a normal PIR (alarm passive) to work as a switch ?
Before transister based sparks old system used points same basis. Back in the day cars could get emp'ed and survived cars these days if emp'ed will 😱💀
What if I have onlu 1:10 ignition transformer what do I have to change in this circuit to have a spark?
can you reverse polarity of ignition coil with flasher relay? ore use dual relays for waste spark singel coil?
I guess this might be done with an automotive relay using the same principle
Where can I get the relay you used in this video?
Radio shack
vengo de tu canal en español, no sabia que tambien tenias uno en ingles
thank you for sharing ...
Would the current be sinus , pulsed or square wave ?
i tried to do it, but even with the cap in the spark jumps in between the contacts of the relay and not in my sparkplug. :( what might be the problem?
You’ve put the capacitor on the wrong terminal of the switch
