I am building a model rocket ignition system designed to launch a rocket from a weather balloon. I need to heat up a small piece of Ni-Cr wire (or similar) to glow red hot in order to light the propellant. I can get it to work (barely) by shorting outa 9V battery with a piece of 36g Nichrome 80 wire, 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?
