  • If there is one thing I'm going to do it is to try this at home.

  • Cool.

  • Kool!

    I have experimented with the 555 great control of frequency though I found it rather unforgiving initially of high voltages but adequate protection allows and liberates high voltages. Ive made basic transistor PWM's with greater durability,but have yet to engineer the extensive frequency range..

    Well done a great video*

  • Could you controll the freguency by music from an mp3 player or what ever that plays music?

  • Very nice!

  • Did you use vdc capacitor, if so, what size? Thats a good arc.

  • Make a jacobs ladder with it!

  • Well, youi can tell the resonant frequency of the coil by the output spark thickness.... Very nice demo!!!

  • Just a little bit higher then modulate the pwm with audio and you have a nice plasma tweeter.

  • Hi,

    thanks for posting this interesting video. may you answer me some doubts?

    1) what is the max. input voltage for it? And how much I'll get?

    2) do you know the output frequency?

    3) May I use it as a primary transformer to provide power for a tesla coil?

    4) The sound of the lightning in your video, is it true?

    Thank you!

  • any idea why only at a certain frequency there are sparks flying ?

  • Whats the secondary current? Looks like sooo dangerous!!!

  • In my younger years, I did a lot of this kind of thing. I also used to take the negative side of the coil and ground it to a water pipe, and put the H.V. tower to my outdoor CB antenna. A nice arc like you have going there was all that was needed to really make a lot of crap on the neighborhood TV screens and radios. That interference signal would go for MILES. LoL.. ahhh, The good old days..... Probably go to jail if I tried that now.

  • "Don't even think of trying this at home"? Are you CRAZY?!! lol

  • how many cycles per minute are you getting with this?

  • how can i apply this to my motorcycle cause im not getn any spark and i tried everything, and everything seems to be in order so any advice would be nice thanks junior......i am so serious......

  • That's the parallel stack of 2N3055 transistors that's driving the coil. The circuit was just a simple 555-based design that I found. I used a IRFZ44 MOSFET on the output of the 555 to drive the transistors.

  • now THATS a tazer!!!!

  • ok i will try it at home! hahahaha!!!

  • If you used a 555 timimg IC rigged for astable operation, you could simply interface a 741 op amp ic circuit to pin 5 of the 555 ic, and connect your MP3, IPOD, etc audio out to the 741 op amp input, this would cause the frequecny output to vary with the audio input, effective making a PFM (Pulse Frequency modulated) signal very similar to FM signals.

  • i have 1$

  • i need the pwm controller for my simple fuel injection im designing

  • the boiling water is ready

  • NICE ONE

  • This is truly cool .

  • what's the name of the song used?

  • They were both snippets from a set by DJ Evgeny.

  • Why is it that when a spark (higher the freq the sparks) the hotter they get?

  • In HQ I can see the post markings and you do have a red connector on - and a black connector on +

  • in a car the + goes to Vcc and the - wire goes to the points or transistorised switch,the secodary fires to - through the turret connection on the coil,I assume it just happens to be a red connector on the negative post and not infact positive?

  • When fitted to a car,the negative side of the coil goes to the bodywork (-) and the positive lead to the points/transistorised switch.the HT side of the coil goes to negative via the airgap in the sparkplug creating the ignition spark,how come you have spark jumping to the red connector?or is it just that you havent stuck to to the red + black - colour coding?

  • Needs more switch flicking :P

  • does the coil heat up? Cuz mine does after a short time... Oh and any idea how hot they may get without exploding?

  • Hahah nice, now how about some music through it? :D

  • That's the next exercise! I've been working on a driver design just for that. I will build two identical circuits for stereo. Or maybe several for surround sound!

  • Can you share what PWM design you used? Is this one you designed yourself, or did you purchase it? I think I have some tests in mind I'd like to perform using a setup like this.

  • Very nice!!!!!!!!!!!!!!!!!!!!!!!!!

  • stick your finger in it.

  • I'll put that on the list of "things not to do!"

  • @anderj101 how about your tongue then! only joking - fantastic project!

  • @3rdSuspension i'd hate to be that guy, but, thats what she said!

  • cooooooollll :D

  • =O Amazing =P

  • ive had similar effects from a pulse width modulator from a ceiling fan and a variable capacitor

  • i recently bought a variable inductor /capacitor, i have messed around alot but cant seem to find a use for this awsome pucrchase..... i have messed in wireless energy, and managed to get a led lit 10ft away from the transmitter, and only using 36 watts to do it. got any suggestion for me where to add this in at, please have a look at some of the videos.

  • can you send me a circuit diagram of that its really cool

  • will an ignition coil run at 27 khz

  • NICE...... my video PC+TRANSISTOR+COIL+12V batteri

  • cool, whats the maximum frequency you can run,

    or can the frequency go beyond human hearing.

    thanks

  • Fried chicken...

  • It's cool to see how the spark changes as the frequensy changes.

  • izz kool

  • hehe, love the equipment

    cool arc character as well

  • That's a cool idea. Might have to try it!

  • at the 1st time its fun next day not any more becouse sparks is not gettting any larger

  • Interesting.

    There is very little info about ignition coils on the internet in terms of construction and alternative uses.

    We know that with higher voltages we have less resistance (more efficiency) I'd love to know how efficient an ignition coil is.

    Also, Tesla also experimented with High Voltage DC, vaporising metals and harnessing the EMF spike in bifilar coils.

    I want to see more!

  • You better watch the temprature of your ignition coil because i have had several of them overheat when i use a very high duty cycle like that.
