i want to use resistors to ignite fireworks. im trying to come up with the best combo of resistor/battery to give me the fastest ignition. so far ive tried 1/4w 10 ohm resistors with 9 and 12v. the 9v ddnt light at all and 12v took about 2-3 secs. id like to get it so i could use a momentary switch to ignite without having to hold it down. anybody have any experience with this?
