I am trying to create an ignition system to launch a rocket from a weather balloon, so I need a system that is reliable, lightweight, controlled remotely (via an arduino relay), and can operate down to at least 0ºC.
I can (barely) get a piece of 36g Nichrome 80 wire to glow red-hot by shorting it across a 9V battery, but it does not work when shorting 9V's in series. Also tried using the same wire to discharge 4700 uF capacitors alone and in parallel without success. What should I do? Do I need to change my power supply or my ignition wire?
