I wanted it to be small and easy to use. You can light most things you can light with an ordinary lighter. Like a candle, a piece of paper or even a piece of wood.
Step 1: Parts and Tools
You will only need:
•A small push button.
•A short piece of nichrome wire.
•A small piece of about 1mm thick solid core copper wire.
•A 9volt battery clip, I reused mine from a dead battery.
•In the bottem of the battery I took apart for the battery clip, I found a piece of plastic
with the same size as the batteryclip. But you can use any piece of plastic as long as it fits.
•A short piece of insulated wire.
The tools you will need are:
•A hot glue gun.
•An exacto knife.
•A piece of metal wire that is about 1 to 2 mm thick.
•A soldering iron.
•Spray paint (optional).
•A piece of tape (optional).
Step 2: The Bottom Part
Now cut about 3cm of insulated wire and solder it to the battery clip as well.
Now you should have something like the pictures.
Step 3: The Top Part
Now cut an other 3cm wire and solder the switch to the two insulated wires.
Cut and bend an other piece of solid core wire into the shape on the pictures and solder it to the insulated wire.
Step 4: The Coil
If you want to calculate how many cm/Ω / Ω/cm it is you need to measure the length and the resistance of your wire. The longer the wire the more accurate the measurments are. My wire was 200Ω and 131cm. To calculate how many Ω/cm it has you devide Ω by cm so 200/131=1,5267Ω/cm.
To calculate howmany cm/Ω it has you devide cm by Ω so 131/200=0,655cm/Ω.
Now use a small piece of metal wire of about 1 to 2mm thick and wind the nichrome wire around it but leave about 7 to 8mm on both sides.
Take the coiled nichrome wire from the metal wire and stretch it out so the coiled piece is 1cm long.
Step 5: Asembling
Step 6: Painting
First tape the parts that shouldn't be paint like the coil and the metal battery clip parts. After that use some spray paint to make it look better.
Step 7: The Result
Unfortunately the battery will drain very fast and will get a little hot so try to use the lighter as short as possible.
I hope you enjoyed the project. If you have any questions leave them in the comments.
