Lightning Trigger - Housing

The results of three hours of work with a drill, a dremel, hand files, and profanity.

Putting the 9V battery inside the case meant replacing the countersunk screws that came with the box with finger-turnable socket-head cap screws. Unfortunately, being #4 screws, they aren't very finger-turnable and will need to be replaced with thumbscrews or something in the future.

All that's missing here is the tiny poke-hole for the reset button, which I added after the unit was built up (needed to know for sure where the Arduino button ended up).
