With the 4th of July around the corner, we thought it would be a good idea to give a controller wrap up and show you how to make some ignitors. Last year we covered a microcontroller based fireworks launcher. If you like the idea of a controller but don’t want to run all the wire, we have the wireless fireworks controller. Adding a little twist to the wireless scene are cell phone triggered fireworks. Maybe controllers are not your cup of tea, you could try to microwave your fireworks. After the break we show you how to make ignitors from a diode and a match.
Using a 1N914 diode, match, and 4 ohm ballast you can make your own ignitors. Using the leads for support, the diode is attached to the match. A current is passed through the device to cause rapid heating. The match head and component must touch one another, in order to ignite. In the video embedded below we show you exactly how.
