In this project we're making electric ignitors! This DIY electronic igniter is perfect for setting off fireworks from a safe distance. It’s a great way to launch explosives without having to use lighters or matches. All of the components fit inside the chipboard enclosure. You can cut of the design with scissors or a cutting machine!
We think this is a safe way to light off fireworks. It’s a great way to get young kids involved. they can light off fireworks at a safe and distance without the danger of burning their fingers. It’s also great for assistive tech so folk who might not have the dexterity in their hands can still set off fireworks.
Circuit Playground Button Input
Our button was constructed out of chipboard and was inspired by the Nintendo Labo. It features a spring mechanism that allows the button to be held momentarily.
We made this into a downloadable template that you can print and cut out yourself. We think this works great with other projects like the Circuit Playground Express.
Inside the box are two 9V batteries, cooper tape and sets of wire. When the button is actuated, it closes a circuit and allows current to flow through the kanthal wire.
Heat Resistance Wire
From Wikipedia, Kanthal is the trademark for a family of iron-chromium-aluminium (FeCrAl) alloys used in a wide range of resistance and high-temperature applications. The alloys are known for their ability to withstand high temperatures and having intermediate electric resistance. As such, it is frequently used in heating elements.
We hand coiled a piece of Kanthal wire, a ferritic metal, to heat up our fuses and ignite our fireworks. The wire is powered by two 9V batterie, which will provide enough power to brightly heat up our coil!
We'll need just a couple of parts to build our own ignition box. Check out the list below!
