Introduction: High Powered Spud Gun Ignition/Thick Blue Spark Creator

About: I'm a proud kiwi, and I have many kiwi traits. Us kiwis, we're modest, you wont catch one of us skiting about our achievements for years. We have our ingenuity, how many great inventions come from (way) do...

Me and my cousin have just made smallish sized spud guns. Just recently the cheapo ex- lighter ignitors just stoped working (Not designed for many pushes. We tried a lot of non grill ignitor or flint methods. As in NZ I can't find either of those. I found an ignition coil in the garage and though 'Why not?' But the sparks sucked. I hooked a camera flash to pump the coil and CRACK! massive thick spark. If you look through the pictures you will see how easy this actually was.

EDIT:- Added new photo detailing the circuit

Also if you are going to use this please wrap your gun in something (Duct Tape, Fibre Re-inforced Tape, Denim...) This spark could ignite a thicker mix than a grill ignitor and we dont want any explosions. Unless you have shedule 80 - 120 please dont get excited with the propellent.

     how do you make one with a lighter?

    cant you make one with a battery and two wires?

    If you had a capacitor hooked up to the battery then yes... if not... then no. Capacitors can kill you so be careful... Use a camera circuit like this slideshow told you to... the capacitor is very dangerous...

    It's really not that simple, I'm afraid. A piezo igniter is made to ignite things with it's strong and short amount of electricity. Those batteries and wires you were talking about would just keep a low but long electricity flow and therefore you wouldn't even be able to ignite gasoline. That's why we use the piezos.

    I have always used a camera flash for my spud gun :) Because it works. I have never tried anything else. I sometimes put a little bit of steel wool on the two screws to get a better spark, that works well too.

    Chuck norrises beard is steel wool

    Is there 250 volts powering 12 volt coil?!

    i was wondering if u could just wire a grill igniter through the coil?

    sorry you dont even need the coil the lighter ignitors make a spark all by themselves

    yea you can use anything even crapy lighter igniters

    That would be the trigger switch

    I am from napier :)

    I know this is a tad old but.... Just wanted to let you know.. a simple 555 circuit and a 12V battery would give you good power also :P I guess that way works too :D

    Is that a full size tool box? This is a great idea and all,but I don't see how it's practical for spud guns compared to spud artillery or spud AA guns ect. Then again,practical has never been something I've been good at.

    Nah, its the little one. About 20in long

    Sorry guys, I couldnt upload the photo... Maybe I can put it here:

    hey this looks sweet i just made a spud gun but it needs a better igniter and this looks good but could u send me block diagram and a materials list ty
