I'm starting with making my own model rockets (100% legally) but I'm already pissed about buying new ignighters every time. I need a device that can electronic ignight rocked fuel capsules.
**broken link removed** this is a picture of what kinda fuel I'm using
I think you are asking for a way to build a device that will ignite the motor with out being destroyed. I suspect that is a very hard task.
Don't these motors come with little igniter wires? Are you complaining about the cost of the igniters? I believe they are just nichrome wire. You could buy your own wire and make them yourself. Probably pretty cheap. Google will find a nichrome wire table that will tell you current and temperature for each gauge of wire. It should be a simple task to put together a controller.
I was new, so i didnt updated my profile, now i have. This is just for modelrockets purpose ONLY! C'mon... a terrorist which is using open forums, yeah right. Just help me with this ignigter please...
BTW, if i was a terrorist, would i trust a homemade igniter then....
“C’mon”????
Terrorist are the ones using unconventional igniters! The latest terrorist videos are on the internet. I think they know about the internet.
When I get rocket engines they come with igniters. I have made homemade igniters and homemade engines. (I have scars to prove that.)
I do know of a way to make a reusable igniter. If you use a hot wire as an igniter, the wire must get very hot to ignite the fuel. A white hot wire is very fragile. The fire from the engine will break the wire.
A glow-plug from a diesel motor might work. It is too big for your little engines. The price is too high, better to get a box of 250 igniters. I hope you have fun with rockets!
When I was young and trying to blow up Alberta Canada; drug stores sold chemicals by the pound. Now we are reluctant to tell Figher-Dion how to make an igniter. Mr. Fighter has a bushy beard and is angry at the world OR he is 13 and flies rockets. I wish we could talks rockets and bombs but the world has changed.
If you know anything about rocketry, and I suspect you dont, then you will know that the only reuseable ignition system is used in hybrid fuel motors.... And even that needs "trimming" after use!!!!!

dude, that knocking on your door is scotland yard...
nichrome wire is a much better way to make igniters. No chemicals to deal with, just a thin piece of wire. not only that but in the US, it is really cheap - I see ebay deals of 30 ft 30 ga for around 3 dollars.

Using Nichrome wire alone is unreliable at best.. Estes igniters have a small blob of pyrogen in the tip..
Conductive carbon black, Magnesium & Potassium nitrate are readily available, and making Nitrocellulose dope is piss easy.. Just dissolve table tennis balls in acetone!
Nothing illegal there, as the police officer who renewed my explosives permit will tell you..
