How to Make Electric Igniters From Christmas Lights

About: I like turning boring things into awesome things! Usually on video.

How to make a quick and cheap ematch to fire displays for the coming year. The ematches used in this video were fired with a single AA battery.

Remember that a battery near an ematch is just as dangerous as an open flame near a fuse. When wiring a display be sure that all power sources are first disconnected from the firing board and all capacitors, if any, are discharged.

    This will work great for cheap igniters for model rockets. Thanks for the idea.
    Would a few drops of candle wax work instead of the cotton?

    Also, if you have a minute I would really appreciate you voting for my firewire project in the make it glow contest!

    Very cool! Another alternative is by using few centimeter of steel wool :)

    dude you rock!
    for my explosives i needed bridge wire and potassium nitrate (saltpeter) but could not find any. i tried everything from copper wire to steel scrubber but could not find any thing that works now i've got it! now i need to get some salt peter only.
    thanks
    P.S. you can use match powder instead of black or flash powder.

    Thank you for your comment. However, I do not promote the making of explosive devices other than legitimate fireworks. Your suggestion of using match powder is dangerous and an amateur shortcut.

    it made smoke literally pour out and looked cool.
    I am not an ametuer
    its just that i can't get the materials for many of my projects and have to salvage most if not all the parts for my projects.
    match powder only makes a flame but yours makes sparks fly out and can detonate the fireworks before the fuse has a chance to.

     

    I don't make explosives as I do not want to join a faction. I prefer smoke bombs.

    very nice. I was looking for a cheaper way to do this. good idea to put the fuse inside of there. would you still need the cotton?

    No you would not need cotton, however the fuse would have to be glued or taped in so that it could not push in deep enough to harm the bridge wire.
