I doubt the speaker wires would have enough power to ignite anything.

Jesus! Will someone tell me how then?!

Timers are far too complicated for my taste...I'd suggest you just use a regular old electrical igniter and some long wire...

What every happened to good old fassioned fuse or 100' of wire and a 12v car battery and electrical ignitors or even several strans of Steel woll It works good if you use a car battery.

Yea, but after seeing those photos I don't want to use fuse. And I'm not sure how to use wire and ignitor. Just hook an ignitor up to some wire and somehow (don't know how) hook it up to the salute or whatever. But I had an ignitor I got from a long lighter and was playin with it and tried to light a firecracker and it didn't!

If I got an ignitor, some wire, and a firecracker, could I learn how to wire just by testing or is it something I have to read upon?!

I could be wrong here, but im just guessing on this:

Well, you still need a fuse, in most cases... the electrical ignitor is supposed to heat up the fuse so it ignites and then lights off the salute.

And you use the electric ignition to light the fuse so you are far away when the fuse actually even ignites.

I don't know if I got that right or not, so don't take my word for it without a second of third voice.

OK, thanks man. So, let me revise this: I tie the fuse to some wire (Any kind? Or does it make a difference?), then I wrap it around the end of the ignitor and hit the button and boom! Right?

No, no, no... Have you ever launced estes rockets? It's just like that. Assuming you are using an easily ignited LE like flash powder or black powder, the igniter goes directly into that powder, not to a fuse first. The wire needs to be thin and have high resistence as tryptamine explained. It's generally a good idea to boost the heat/flame output of the wire by adding what is called a pyrogen. This can be just about anything that easily ignites, like a blackpowder paste dried onto it that will help ignite the main charge. The leads to the igniter are connected to your long wire and when its hooked to a batter the igniter heats up and lights your stuff. It's really very basic. I still don't see why you are so averse to using fuse if this is too complicated for you...

Yup... I was wrong like I might have figured.

But when the salute ignites, some of the wire will be blow apart (wont it)?

Could you attach the wire to a fuse though, to save a piece of wire from going bye bye?

Unless you are setting off something VERY big, you'll have minimal damage to the wire, a few inches might be messed up. Wire is cheap anyway.

i used an estes igniter to set off my first COB so i used the battery powered device to set of the igniter and it took off the clips on the end of wires attached the yellow launch thing.

Clips are pretty weak, but the wire itself is fairly tough.

i guy in our club is an electrical engineer and he is designing a controlor that will be able to take sequanced programming and multipole devices rigght now the current one takes 8 devices

the one we are designing in our spare time will have a continuity test .. a resistance test battery power test and multiple othe status features .. it will not have the tradtional ground wiring but more or less have a digitaly encyrpted signal sent to a relay box which decodes the signal and sends back a conformation signal and then the box sends the encryptered firing signal....

it's a very complicated design but it should be worth it due to large range we wil have VS the less cable we would need to buy (which is very costly might i add)
