Electric igniter /Matches

Can anyone advise me on how to electrically ignite somthing. I have read about electric matches. Any help greatly received. :? :?

Years ago we used to light firework type rockets on a Huey gunship helicopter with a "hot wire". Simply a length of fuse wire between the terminals of a battery, through a RC switch. Never burnt the helicopter out of the air, and when the rook scarer (that was in the tip of the rocket) went off, it was quite something!

Hi there,

I normally take a 12 volt cigarette lighter as used in cars. Works great and is relatively safe. Mind you, it draws quite some juice.
If you prefer a lower voltage, you can use a glowplug as used in RC methanol engines. They will work on 2 volt, but the resistance wire is more fragile.

really cheap option is to use igniters for model rockets.

Hot wire works for most things and is cheap and simple. Pyrodex, black powder all go using hot wire. The wire is fairly safe but the after affect sometimes is not so.

i might be going abit off in here, but maybe you could use a dc-dc step up voltage converter, and store the charge inside a tough capacitor... then have wires leading out of this capacitor, one is fixed somewhere and the other is at the end of a servo horn or something, bring them close together you would get an arc of electricity that you could use to ignite stuff...

well it sounds abit far off, i doubt that it should be taken seriously too...

Basically your idea will work fine, but high voltages are difficult to control.
I have some experience with a flash unit in my 1:8 Tiger. I wouldn't want any electric arcs jumping around in my tank. Not only for the risk of a fire but also for the interference with the other electronics. A hot wire is definitely easier and safer.

So that you keep your fingers in place I recomend that you use model rocket initiators, they are cheap and work 99% of the time, it cuts out the long walk back to the explosive device with your fingers in your ears and a lampshade on your head cheers Phil.

i used to be a ww2 re-enactor and used este rocket ignitors for all sorts they are £6 for a pack of six and are easily available from most radio shack and may even be cheaper online like last post said its the safest option and will reduce any dangerous misfires/accidents!
small pleasures are last refuge of the complex
