Hello, I'm currently trying to build a remote control igniter for my rocket. What I used to do before was using steel wool to light a match which ignited the rocket, so I had a long wire with a switch to close the circuit. Now I want to have some fun and try to build my own remote controlled igniter.
Bought a really cheap remote control car and my plan was to simply take the motor connection and instead use it with the steel wool bridgewire. At the first try the steel wool just slightly burned which was not even close enough to light of the match, then I tried to use a darlington transistor to instead of connecting the motor wires directly to the bridgewire I conncted the + to the base and the bridgewire then was connected to the collector and to a +9V. The wool still didnt burn enough, I replaced the wool with a little electric motor to check my design was correct and the motor worked perfectly (rotating when pressing the remote control).
My first guess is that the voltage to the motor is pulsed and so the wool doesnt heat enough from pulse to pulse to heat enough.
Any ideas guys?
Thanks
