A 10 ohm quarter watt resistor is overloaded by applying 12V across it. It burns and ignites the fuse it's taped to.
Must be the cheapest way to electrically fire your home firework show.
(Note the use of a traditional quarter watt, 10 ohm carbon film resistor. These burn better than metal film ones.)

So… Now the problem is, the fuse on the fireworks are cheap and don't always light… Resistor is burning fine, but the fireworks are the problem.
As a kid, I used fuse wire and 12V battery charger as remote ignition/detonation devices for various pyro projects!
Who has come back to watch Clive's first videos

100 for £1.80 or 10,000 for £32
I know which is more value for money… but I SERIOUSLY don't want 10,000 resistors!
Is it reusable?
Can a diode achieve the same magnificence?
never understood the spark plug firework. Dad picked one up in China once (oops) has 5 inches of copper wire and supposed to attach it to a spark plug and it does its thing . 1 . Seriously? 2. bit dangerous if it goes bang around the lawn mower 😛 Can't remember if we still have it. It's 20 + years old and nobody has the courage to try the thing so it always gets lost 😛
What I've done in the past was use a power strip and the majority of a PC power cord instead. I'd unplug hte cord, obv, then I'd take just one strand of the Line and Neutral wires, twist them together, twist them around the fuse of the firework. The power strip gives me a switch, with it switched off I plug in the cord, then flip the switch. Fwoomf~! And it's much more efficient than burning up a resistor every time.
Perfect for controlled pyrotechnics from a distance. After setting up you could easily time when individual fireworks start. Running cables, you could be a good, safe distance away too.
thats called visco fuse
hahaha! You are so amusing Clive! The way you react when the fuse catches!
in the US radio shack charges like 4 bux for 5… gay! I ordered em from thailand, just have to wait now… I googled metal ones and ignitors, it simply said, fireproof and metal resistors never catch fire, even at extreme loads =)
I only tend to use carbon film resistors, so I can't say how a metal film one would react. But a 10 ohm quarter watt resistor should still get white hot before it fails. Are you sure you have 10 ohm quarter watt resistors, a 12v supply that can deliver the current and decent cables to avoid voltage drop?
Standard carbon film quarter watt resistors are readily available from most electronic component suppliers for extremely low cost. In the UK I'm paying about £3.46 (just over $5) for 1000.
what a dummy, metal ones are flame proof, so since no1 seems to mention it, USE CARBON resistors! Now i gotta wait a long ass time again from thailand or china
