Lighters are inexpensive and can be found in almost any convenience store in the world. But even though there are no shortage of these devices, it can still make for a fun little project to build your own. Because there are electrical components involved, this isn't your average simple crafts project. That beings said, you'll be pleased to find that if you possess a little technical know-how, you should be able to completely manufacture your own homemade electric lighter in only a few minutes' time.
Insert the two AA batteries into the battery holder (available from any electronics store). Locate the two wires sticking out of the end of the holder and use your wire cutters to cut one of them down so it is about a half-inch long. Strip a small portion of the wire sheath off to expose the metal wire underneath.
Use your soldering iron to solder the push switch (available from any electronics store) to the end of the exposed wire. Wrap electrical tape around the top of the battery holder, securing the push switch.
Use your wire cutters to cut the remaining wire down to about a half-inch in length. Then strip a small portion off of the end.
Take a length of metal wiring (no sheath) about three or four inches long and wrap it around the tip of a pen or pencil to form a cone shape. Make sure there is only about a half-inch of wire left after forming the cone shape.
Solder the end of metal wire to the remaining wire on the battery holder, making sure the cone end is sticking straight up.
Press and hold the push switch to charge the wire and create a lighter. Touch the object you wish to ignite to the metal cone to light the object.
