Diy ignition coil driver Videos

+TinselKoala Sweet... I'll make note of it.

+Christopher Mayeux145 Hz.

Take your time... no big rush.

+Christopher Mayeux I'm sorry, I can't remember off hand. I'll have to set the circuit up again and measure it. It's put away at the moment because I'm working on something else. I'll get it out and make a measurement a bit later on, perhaps tonight or tomorrow.ETA: Ah... I see in the Description that it is running at about 145 Hz.

+science VlogYou're welcome. Please let me know how your build works out.

okay, thanks

Probably. I have tested this circuit with IRF530, IRF830 and IRFP260n. But I haven't got a 630B to test. It will probably work fine, just watch the temperature.  The lower the on-state resistance (Rdss, check data sheet) the better.

I can't afford to buy another ignition coil, but look what happens when I put another battery in series with the coil drive: Misc Circuits: Ignition Coil Jacob's Ladder Demo 2: 24 V to Coil

Link is in the Description above. Thanks for watching!

uses around 9 or 10 watts somewhere around there it wouldnt light a 15 watt auto lamp just a faint glow

@m3sca1 it could be drawing more than that underload idont know

might not light an incandescent but what about flouro?

i get ya now-thought you meant the secondary side...

i have anotehr video that shows how

@GalaticTG no you touch it first

touch it!!!!

fake 101

Great video

+Phil Crockett NO! You want the cheap stuff. Let people use it twice to get them hooked and then it breaks so they buy another one! IT'S THE CHINA WAY!See ya at Wal-Mart!

+Shamrock Rancher I really wished I'd had an old broken plumbing snake that I could have used...... It would have been so much stronger, and may have allowed more torque. Thanks for the nice comment. God Bless You.

@Computerbusters Oh, some misspelling. Well, sorry for making that mistake, I do know what a CPU is. I hate when i misspell. But thanks for correcting me, English is not my native language, sometimes some misspelling do occurs. I wonder why I made this mistakes?

@Digadogup hmm.. I've made mine from parts that i had lying around (not ic or irf) But you can probably find all your parts in a CPU (computer power supply) They contain severals caps, MOSFESTs, and resistors... You may also find the ic in a timer circuit :D

i didnt kno u did ciruitry? i thought u just did chemicals and stuff (thats why i subbed to u) also u need to do some chemistry related vids u havent done one in like 2 months

@MrRealgamer777 I do some electronic/circuity... I know!! ... i have like 4 different videos to edit ^^ I'll try to post all of them by the end of the week!

@ErikDIY sorry but just had to... CPU is an acronym for Computer Processing Unit. PSU is for Power Supply Unit!

awesome , iv wanted to make a flyback for a while now i just cant get the parts in australia

@Computerbusters lol yep a cpu is an integrated circuit it uses power doesnt provide it

Incomplete assembly, no schematic, no demo... LAME!

Could you please send me the schematic you used?

Oh! This system is very small. It's nice!!

@ErikDIY please may i have the schematic?

Где схема, бля?

+Mostlymacros Cheers! rewatching so i get the whole thing :)

+ElectronHV Thanks! No problem about waiting. I still don't have my own computer on line so I don't comment or post as often as I'd like (I need to use my wife's to do this). Next month I will be on here more. I'm pretty sure I mentioned the core and related concepts in the video although not in great detail. I also show in this video one taken apart in a jar so that you can actually see the laminated iron core but it may not be as visible as I wanted it to be on Youtube. You probably know all this but for the benefit of others I will explain: Typical Ignition coil design is A BIT like some old Marconi coils or somewhat like the original Ford coil (without a reed of course). Just a few strips of iron for the core but modern coils are lacking a built in reed interrupter for powering from DC directly. And of course, usually ignition coils are in transformer oil. The core actually connects to the secondary and is the output HV. The other side of secondary being tied to the primary on one side so unfortunately the only way to put them in series is with phase polarity. So really can't hook them in typical secondary series to get even more voltage (X3 or more). There are limits to the core and other factors as well. My biggest problem was insulation failure on the top at power levels this high. I was getting something like 80-100kv around 7ma in one video (700W) from the two coils primaries in series. They also can get too hot and could melt internally but this has never happened to me. For high voltage power I have far better transformers, some I have not shown in videos yet. I believe I basically reached magnetic saturation in one of my videos and thus close to maximum possible output voltage for these particular coils. If nothing else the biggest problem I had was an insulation breakdown to the point where plastic carbonized and the coils were both ruined by arcing from HV to primary terminals. If there is no arc present or other large 'load', the power tries to go somewhere and breaks through plastic. This is only a serious problem at high power levels. Each coil is producing 40-50kv or more! That's why I made such a point about having an 'arc-load' to prevent coil failure. After I made the original video of a circuit like this in action, I moved them too far apart and tried for even larger arc lengths! This caused top-contact insulation breakdown very quickly! With ballasting and/or lower voltage you can run them without worrying about this so much. I found about 500-1000Hz works very well in drivers like this. As you know ferrite cores typically do well at higher frequencies and have different characteristics depending on how the core is constructed. For a dental head transformer I converted to AC (Helodent); the large ferrite core works well at about 8000hz-10000Hz or more but interestingly not much more. These ignition coils were cheapest I could get on Ebay, some have far better insulation. I don't use them much but they have potential for some uses since they can handle a lot of extremes. I just wanted to see how good of an HV source they could be and how far I could push them. I created this instructional video because of a request from another YouTube user. I used a pretty minimalist half-wave circuit here but it works well. Thanks for the compliment. Again no worries about waiting on comments, we all have other stuff to do. Thank you for welcoming me and your comments, I really appreciate them. I enjoy being able to learn new things as well as teach people things. --G.Beasley
