tiny mini

[cardinals08]

I made a mini out of a pen tube for the chamber and a 3.5 inch 1/8 inch ID piece of clear tube. I haven't been able to fire it yet cause it is nearly impossble to get the fuel/air mix right. I think it is because the chamber is too long and narrow. the spark jumps the whole width of the chamber so the spark isnt the problem. I got it to fire a couple times with the cap off but I couldnt see a flame, just heard a small noise, only about as loud as clicking the piezo. I hope to get it firing, I know the range will only be about 20 feet tops. Ill post some pics tomorrow.

What fuel are you using? For stuff like that I just modify a normal disposable lighter.

Im using butane, I should probably get it so I can but the fuel in at the bottom or middle rather than up at the top
