Introduction: Piezo Electric Ignighter

Picture of Piezo Electric Ignighter

In this instructable, i will show you how to turn a barbacue lighter into an ignighter for use inspud guns and other projects. It should take around 5 minutes, which is why i'm submitting this as a PopSci 5 min. project.

Step 1: Step 1: What You Need

Picture of Step 1: What You Need

You will need:
Soldering iron
Copper aligator clops
Wire holder standy thingy

Step 2: Step 2: Taking Apart the Lighter

First, get a lighter that is empty. Get a flat screwdriver or knife, anf cut the stickers. Then unscrew the two screws. Also pry off the grey cap that holds together the end of the lighter. ( second image )

Step 3: Step 3: Open

Now carefully open the lighter.

Step 4: Step 4: Undo the Shaft

Take apart the long black tube by pulling away from the wire and hose. Then pull the small plastci cap off of the end.

Step 5: Step 5: Remove

Remove the fuel canister and the locking mechanism, you will be left with this.

Step 6: Step 6: Solder Part 1

Solder a wire to the shorter one connected to the piezo-electric ignighter.

Step 7: Step 7: Re-Assemble

Now put the whole thing back together, make sure the wires are coming out where the black tube came out.

Step 8: Step 8: Soldering Part 2

Now solder an aligator clip to each wire.

Step 9: Finish

Now you have a custom made piezo-electric ignighter. You can now use it in spud guns, and other projects that require a small explosin!

Step 10: Video

This is a video of the sparks, sorry for the bad quality and mistakes.

Step 11: Thanks

will the spark arc over around 2 inches?


XOIIO (author)sharlston2009-08-04

Depending on the metal, you could theoretically get a bigger spark but it doesn't have the power to go even one inch. It's just like a carpet shock. For two inches you would need a wimshurst static generator and gold or silver leads. Unfortunately they are very expensive. You could try googling how to make one though.

get a grill igniter.....ive gotten 4 inch sparks with those haha.....sparking a tin can with one wile holding the very top of the can with just hardly and skin will tingle your whole arm haha

thanks ill see what i can do ps thanks for subscribing

correction it's called a wimshurst electrostatic generator.

would this work for fireworks?

XOIIO (author)schoonovermr2010-04-18

It could, but it would be much easier and more reliable to use a fuse.

I do this but cut the bottom of the lighters off And then Use a zip tie or a Jubilee Clip (Hose clamp for you americans) to hold it onto my spudgun

XOIIO (author)stephenniall2009-12-29


LOL JK that sounds like a good idea too.

I tried this for a rifle modded potato cannon (Instructable coming soon) and it works great seems like a real gun.  I was just wondering how long the battery lasts.  Tho I love the idea simple and effective.  I would recomend leaving the safety on to stop accidental misfires the but great job over all.

XOIIO (author)koolkid122009-12-04

There is no battery! A tiny hammer strikes a piece of quartz and makes a charge, lasting thousands of times!

I love piezo electric thingumies, i took one to school and tazered people but then they confiscated it :( 

garyrowl (author)2009-09-18

that's all I wanted to know, cheap and cheerful, just the facts 'mam, cheers buddy.

sharlston (author)2009-08-08

how do the spark thing work?

XOIIO (author)sharlston2009-08-08

I'm not sure exactly, but there is a spring mechanism that when pressed, a tiny "hammer" strikes a piece of quartz, that is what generates the electricity.

sharlston (author)XOIIO2009-08-08

oh i tried slodering that little metal thing at the bottom today and it just fell off

XOIIO (author)sharlston2009-08-08

Well, if the metal tab came out of the ignighter chamber I'm afraid you can't do anything about it. Good news though! You can buyighters at the dollar store for only one dollar.

sharlston (author)XOIIO2009-08-08

yep i got some refialble with uv torch 5 for £1 or $2

NYPA (author)2009-07-23

Don't quartzes carry a piezo electric current?

XOIIO (author)NYPA2009-07-23

I know they do, but google it for more detail.

These are also great for zapping people.They don't hurt enough to kill but they give a nice shock.

XOIIO (author)bylerfamily2009-06-05

Ahhh yes, such sweet memories... Even better when you get them in the back of the neck!
