My mini cannon

[Spedy]

Here's my Mini. It's one of those new clear HDPE film cans with a pen tube and a piezo strapped to it. Currently it's a sort of "spray and pray" thing with the not-completely-empty butane tank from the lighter I cannibalized. around 1.5 seconds seems to do it...

It'll send a spit wad clear across a room, at least 30 feet. Stings at 10ft.
For some reason I haven;t tried q-tips yet and all the tic-tacs I had available were jumbo-sized ones. I imagine normal tic-tacs would leave welts..

I took a picture of the spark-gap, but it was all washed-out looking..
>.< file size too big can;t attach pix..

Bigger close-up, couldn't choose between this and other one..


There yah go. Tell me what you think!

Is this one those things were you just used what you had to built something, I love those.

Butan seems to be a good choice of fuel for mini's. Is this your first mini? Pretty cool! I've read where Axe body spray works good also, 2 pumps is what I read.

Awsome I love minis

[Spedy]

This is my first mini. I used butane because it was handy, I mean I just took apart a lighter to get the piezo so i figured "why not?". I try to avoid Axe because I think it smells dreadful.... how it manages to sell I'll never know..

Pizlo: yes, it was just " one those things were you just used what you had to built something". It's a pen tube hot-glued to a film cannister and a sparker stuck to it with electrical tape.

Anyway, thanks for the comments.

I'm eventually going to replace the solid-core wire connecting the piezo to the spark gap with more flexible stranded multi-core wire, because the solid core stuff is starting to get metal fatigue...

Lol, how is hot glue standing up to a mini combustion? I agree with you Spedy, Axe does smell dreadful.

[ghostman01]

hot glues good for minis lol ive only used it once on my minis but i shoot mine using airsoft bb's for skirmishes

[Spedy]

The hot glue is holding up really well so far. It was mainly used to anchor (spelling?) the barrel. The hole was originally really small for the barrel so I didn't need to use a ton of the stuff.... I'll have to take a pic of the inside of the chamber at some point.

Also, I forgot to mention that I used a staple as an ammo stop in the other end of the barrel...

good idea with the staple

[Spitfire]

doesnt the piezo's spark gradualy get less and less untill it just dies?

Iv stoped useing my mini ( http://www.spudfiles.com/forums/syringe ... 13000.html ) because of that problem

[ghostman01]

The only BBQ that i have is solidly epoxyed into my combustion. And I got it through my couzin, so itl take a while before i use my mini again

I find that the piezos from Scripto lighters are REALLY high quality and don;t ware out unless there is some odd defect. Unfortunately, that isn;t a Scripto piezo, but the one I'm using now doesn't seem to be waring out anytime soon..
