The end of the extension cord were you use a jumper cord and that fires the cannon.

The ammo was a really big potato and the target was some 1/2'' plywood.
Here are some pics of the ply wood-

My camera wont take any good ones anymore, I dont know why but I will try again.

I think the auto focus is off. I find if you hold the camrea really still while taking pics they are a lot clearer.

You need way more light, even if it looked light enough to your eye. The best light is from behind the object facing the object, pointing to it.

What size is your meter and how much volume is in it? I have the same chamber volume and i have a regulator. I'm going with 3/8 pipe size because when i used 1/2 inch it was too big.

I don't have the cannon anymore, I forget what size the meter was but you can use the Burnt Lake calulactors to figure out your meter.
This is to find your chamber volume-http://www.burntlatke.com/ratcalc.html

And this is for the size of your meter pipe- http://www.burntlatke.com/ft_live.html
