Can you make a firework or rocket igniter from a microwave transformer? Answered

For homemade kno3 rockets that are really hard to ignite(usually needs a lighter).
If i were to guess id convert it to DC, run it through a 12 volt battery, Rig a switch.
Just a thought it would be really cool if you could rig a cell phone to it stand far away and call it for ignition.

I haven't tried this, but maybe you could use the leads going to the small motor inside the cell phone and connect them to a relay. (Most cellphones use a motor with an unbalanced weight to make the phone vibrate in silent mode) You would still need an ignitor though, and I have no experience with KNO3 rockets but I am very familiar with model rocketry. If these rockets are hard to ignite, you could make your own igniters with more pyrotechnic material. Take a standard roadside flare apart, mix the powder with a little bit of water until it becomes a paste, and put it on the tip of your wire and wait for it to dry. Good Luck!

Transformers only work on a/c, unless you are using it as an induction coil, which it wouldn't work very well for that.

A better idea might be to put the battery close to the igniter to keep resistance losses low and switch a relay to control it.
