Ignition coil driver circuits and experiments

[steven2]

with my latest single output hv ignition coil driver circuti in the green pvc circuit box, i decided to exsperiment with it some more, and with just one multimeter probe at one of the output terminals i can still get tiny arcs jump to my skin, and ive allready tried some skin exfoiliating with it. i decide to take out of my parts draws 2 camera flash tubes, that i had with others from my former simple plasma tube exsperiments, posted in the high voltage stuff section. now i had 3 tubes bundled together and solder together at each end, and as i held one end the other end, i touch the probe from my ignition coil driver unit, to it, i was exspecting plasma like arcs or electrissity streamers to flow through it, but instead the end of the tubes i was holding lit up half way with a purple glow, i then held each end between my fingers and with the hv probe i touched the glass of the tubes one at a time, and although glass aint conductive , each tube i touched lit up completely with a purple glow like energy. not white like a flash tube normally dose when in the camera. , i kept wondering why it all glows purple when i touch the glass with the probe while holding each solderd end in my fingers, so i had a closer look useing my dome lense and can see tiny arcs from the probe tip going into the glass. like energy from a plasma display or similiar , but if glass aint conductive then i cant exsplain how this is happening, really . if you think this isent unusual, ive had neon globes glowing pink in colour in a former exsperiment , and i dont think its in the colours of the rainbow iether.

my exsperiments are going good the erea of the skin with a freckle on it , that formed into a small scab after treating it with this circuit, i accidently knoked the scab off and under it there was just a light pink spot where the skin is healing and the freckle completely gone.

here is a picture of one of my green colour, high voltage tripplers, these are few and far between and in australia , ive pulled many tv-s to bits and i rarely find these, unlless im lucky, this high voltage trippler , when used with one car igni5tion coil driven by an ignition coil driver circuit, will put out triple dose high voltage arcs, in my postings youll see one and another larger one that is square and black colourd

powering just one ignition coil with the ignition coil driver circuit puts out an arc that i could allmost compare with the small arcs put out by the disc shaped flyback transformer without a biult in high voltage trippler, so i reckon i could allso use the ignition coil powerd by the simple to biuld ignition coil driver circuit to charge up these high voltage photo flash capaciotrs, allso so ill be testing that out as soon as i grab a few more ignition coils from the car wreakers for $5 each,

i was searching for the xenon lamp igniter circuit and yours is very helpful hints for me to develop further if you have any ideas please send me the details and i will coopreate with you for ever for any h

with these high voltage circuits i biuld as prototypes ,with the schematics ive collected, ive put them upstairs in the main bedroom right next to my side of the bed , and in the home made pvc circuit boxes i designed. ,2 of them circuits have a 12 volts rechargeble lead acid cell battery in them . now the ignition coil driver circuit i use to create hair thin arcs for skin exfoiliation etc is at the bottom of the high voltage units and ontop of that unit is another circuit with no battery in it , now what happend last night while haveing a shave , i decided to switch on that bottom hv circuit , to see if the 12 volts lead acid cell battery inside it is , still ok. and when i did that the led on the next high voltage unit ,on top lit up , when there was no battery in it. so this good bit of induction from an ignition coil driver circuit with coil able to induce that bit of voltage into the circuit on top to light that led with no conections made is intresting, and all my pvc circuit boxes are insulated with varnish to,

Hi Ante,
Here is a high voltage limitation that we haven't discussed:
The spark coil's core is going to saturate with a particular amount of current through its primary, which is determined by the voltage that is applied to it. Then applying more voltage than that won't make any difference to the voltage of the spark.

True but won't a higher voltage cause the core to saturate more quickly thus causing a higher voltage?

Once I was using a 240V to 6V transformer in reverse to generate more than 5kV from 12V. I foolishly decided to discharge a 340V 1uf capacitor though the 6V coil, it didn't cause any damage the first time as the spark gap protected the secondary from arc over but the second time it left it open circuit and the transformer secondary became short circuit.

hotwaterwizard not that it makes any difference (unless you're powering this of a car cigarette lighter in acar) the +- terminals on the coil are the wrong way round. You could also make the circuit more efferent by using a power MOSFET.

also try different values for C try 220nf and 47nf.

alun thats the ignition coil driver i use and i use the irf540 n channel mosfet, and on another i used the irf740 mosfet , and with the irf740 mosfet the sound of the circuit in action is low frenqeuncy

I have quick question.  Can an Ignition Coil Driver make a good Capacitor Charger?  I'm currently working on a coil gun, and its working just fine for the exception of the charger; its just too damn slow!  I used a voltage multiplier as a charger; the capacitor bank is 900v @ 4500uf.

Any advice? 

 

[steven2]

hey raptor2021 this needs more exsperimenting , now if you havent seen my posting in the high voltage stuff section, of the high voltage photo flash capacitor charger,. it uses a disc shaped flyback transformer , without the biult in high voltage trippler , now i tried an ignition coil before useing an ignition coil driver circuit , and the same parts i used  for the high voltage photo flash capacitor charger, but somehow it dident work with the ignition coil driven by the driver circuit , but if you look on the net there was a cheap coil gun that uses the photo flash capacitor charger from a camera and it had a few photo flash capacitors in parralell i think it was  and that looked ok , so it would be easyer to biuld the version i biult, that uses a flyback transformer driver circuit and use that to charge a few capacitors in parralell then use that.. the disc shaped flyback and ignition coil  both put out ac when driven by the driver circuits but i think it may of been the frenquency they were driven at  may be the unkown facter as to why the flyback can be used and not the ignition coil , so ill try something else next time and if it works ill let you know ,  it would be great to have a high voltage capacitor charger useing an ignition coil ,as the 2n3055 npn power tranny would last longer that the n channel mosfet i use, because there so static sensitive they get damaged easy , so ill try when i get around to it, and  this time ill use some of the parts  i use in the high voltage photo flash cap charger driver circuit this time and see how it goes then

The answer is yes you could but you'd need a diode on the output to prevent the capacitor from discharging back into the ignition coil, and you'd need another circuit to shut of the power when the capacitor voltage reaches 900V but it could be done.

 

[steven2]

i did try useing an ignition coil for a capacitor charger  and i used the same parts i used for the high voltage photo flash capacitor charger , thats the diodes and resisters and neon but it dident work so i think ill need a chain of diodes instead of just 2 like in the high voltage photoflash capacitor charger

 

[steven2]

ive may of allready mentioned this but when i switch on one of my portable ignition coil drivers with single ignition coil in it and allso 12 volts lead acid cell rechargeble battery  , the neon light on the high voltage photo flash capacitor charger allso comes on and that unit sits on top of the ignition coil driver circuit  i measured  1.45 volts  or more  at the outputs of the capacitor  charger when i switch on the ignition coil driver unit under it , so im getting some transmission of voltage here by the looks of it , or just induction  from one unlinked circuit to another , and even more strange dispite my usage of the high voltage photo flash cap charger i exspect  the 12 volts battery to be low by now but it seems to be still over 12 volts so why aint it getting low on power  ive used it a number of times . it should at least be getting low , now here is a picture of some of my high voltage units sitting on top of each other , makes you wonder if the operation of one is keeping the charge up on the other by induction, i will do some more exsperiments and see if i can double the induced voltage at the high voltage cap charger, when i switch the ignition coil unit on and see if maybe  i can recharge them all or keep them in charge by the induction from one high voltage circuit  alone

ive made an error here im not getting 1.45 volts im getting 6.99 volts output from my switched of high voltage photo flash cap charger via the induction from the ignition coil driver when i switch that on , even though the neon dose have a voltage rateing of ,well in this case its  pritty high for a for a 6.99 volts output  to be lighting it , maybe i should  try see if i can get more higher voltage readings by touching my meter probes to the neon  serounds

 

[audioguru2]

The bottom one in your stack of them develops a voltage from the heavy weight on it! ;D

 

[steven2]

thankyou for the humour audio guru , i decided to measure the outputs of all the high voltage units that are all turned off and with just the ignition coil driver with coil on, and starting at the bottom one i got a small voltage reading from the induction  and as i measured the others and as i got closer to the ignition coil driver unit that is on the voltage reading climbed

 

[steven2]

hhey raptor2021 yes you can use an ignition coil for cap chargeing view the latest posts to the topic high voltage photo flash cap chargers youll see it there

 

[steven2]

the ignition coil driver dose have some good uses in exsperimenting with arcs and since ive come up with the simple capacitor charger in the other topic for chargeing capacitors up with by the use of the ignition coil with its ignition coil driver circuit  , here is a recreation of one of my parralell ignition coil setups , i just have to put in the negative return wire electrode, these really crank out some great arcs but even better i once used a single ignition coil and i charged a cap up and dumped it into the coil and got better arcs from it, you may be able or should be able to do the same with the parralell ignition coil set up. so ill biuld another high voltage photo flash cap charger and include the coils so just switch it on to charge up and select object or  pesty critter to be zapped then when ya charged the cap up just push a button  and dump that charged cap into the parralell coils and fry that critter , like in the case of pesky skunks , the parralell coils ive made 2 ignition coil holders from pvc pipes for them  so just run it off the simple ignition coil driver i even ran 3 coils in parralell of the same driver once

[steven2]

with the parralell coils i have 2 or 3 arcs but the first hv out on the first coil to the second hv out are the bigest arcs if you space the first hv out electrode far enougth apart  now i dont know if its nessisary but here is a mini spark gap just in case,
