Stringy Vice

After taking apart the air cannon set-up, I put the pellet set-up back together.

 

And the trigger didn't work.

 

I spent a few hours looking at the circuit and it works just fine. So I put it back in and everything works fine.

 

My theory at this point is that trigger circuits are self centered little bastards that just need attention from time to time in order to function correctly.

 

The theory fits the data :-)

 

So this is some fiberglass-ish strips being hit by a pellet.

 

Cheers.
