An electrical match

Step 1: Things You Need :

you'll need these parts:

Some matches
some electrical tape
obout 12 cm of flat cable

and these tools:

wire stripper
and a pair of snippers

Step 2: Prepare the Cable

take two of the wires in one piece and pull the ends apart. Then take your wire stripper and strip down about 1,02 cm of the insulation.
Now take two single strangs and twist them together.

Step 3: Prepare the Matches

take your file and make a little grove inside of your matchhead.
After this take a pair of snippers or a knife and cut it in half

Step 4: Assembly

take the half match, position it between the two leads and bend the two twisted wires over it so they go through the litle grove you made earlier.
Now take the two, twisted together, wires and twist them together with the others.

Step 5: Final Step

Take a piece of electrical tape and fix the whole thing.
and Finally take a pair of scissors and remove the excess cables, but be careful there not to cut the twisted connection of the thin cable.

Step 6: Have Fun!

To ignite it you only have to connect the two leads with a strong power source.

<p>what's th minimun voltage/current for th &quot;Strong Power Supply&quot;.</p><p>i want to make one for arduino and control with it.</p>
<p>The power of an Arduino wont be enough, In your case I would use something like a Lithium Batterie which can deliver the needed current.</p>
<p>but can I use (relay) right :) I want to make for fire &quot;cuetes&quot; this is the name of fireworks on my country :) </p>
<p>yes you have to use a relay :)</p>

<p>Nice, I've seen <em>The King of Random</em> do this before</p>
King of random has practically done everything!
<p>If it's random, He did it!</p>
<p>Ok sorry, i just tried to find it on instructables an i couldnt find an identical instructables </p>
<p>Wow. 1,02 cm of insulation. You must be a very picky guy ;-)</p>
<p>&quot;about 1.02 cm&quot;</p>
<p>I'm German - probably like the author.</p>
<p>btw: do you have any measures what current it will draw at 5V?</p>
i don't but if you want some i could make some.
<p>I guess that would be interesting for others too. E.g. to start your New Year's firework controlled by an Arduino. In that case you likely need a good power source and some fat MOSFETs.</p>
<p>hey ThomasK19 I've used an akku which was charged at about 7 volts and I measured about 10 Amps for a second or so(I can't say exactly how long because my amp meter has got a little delay) . So if you want to use them with your arduino you definitely should use some sort of relay and a strong sort of akku(in my case an NIMH).</p>
<p>If you use an 1&Omega; resistor with an 0.25W power rating at 5V, you should be also able to ignite the match. At 5V an 1&Omega; resistor is going to draw 5A, so to do this you obviously need a high power transistor with a high gain (a high power darlington should be perfect) and also you need to power the microcontroller from a source that is able to supply at least 5.5A.</p><p>By the way, the reason you measured about 10 Amps is probably because your power source wasn't capable of delivering more power, what you have here is a short circuit and the only thing that limits the current is the output resistance of your power source and the resistance of the wire which is extremely small. If you are using a power supply that doesn't have an option to limit the current you need to be very careful not to damage it.</p>
that with the 1 ohm resistor, i have seen too but i thougt i will try this first <br>
<p>Thanks, both. Maybe it would be wise to charge a large capacitor and short circuit that with a MOSFET to get a large current for a short time. I might experiment with that. </p>
<p>I think a large capacitor is the best way to go. By the way, if you actually try it keep us updated.</p>
<p>It's a short circuit, so the intensity must be very high. A simpler system is use iron wool ! I did that for firing my rockets when I was young, and it worked each and any time.</p>
<p>I've tried iron wool too but this is a mutch simpler way. If you do it like this you kan make a much higher quantity of igniters and if you have a good power source it doesnt matter what methode you use</p>
<p>And if you want to you can also use one single strang, then it will not need such a strong power source.</p>
<p>This would be a great way to make remote igniters for fireworks.</p>
