PCB Layout software: Originally I began designing parts in Cadsoft Eagle, but a friend of mine who was working on a project for the FAU marine robotics club demonstrated a much easier way of creating part footprints in a program called Copper Connection. It took some getting used to, but once I learned the interface I uninstalled Eagle alltogether. Copper Connection allows for multiple layers and exports designs in the same way Eagle does.

Essentially what you are looking at is an Arduino Pro-Mini. The JDAM features an ATMEL ATMEGA328p-au running at 16Mhz and powered by 5 Volts. The main board has the following features:

3 hardware debounced push buttons for accessing the menu and making adjustments
1 hardware debounced OMRON D2F lever switch to act as a trigger input (also used for menu input)
1 2-position dip switch which controls the tournament settings lock, and the eye logic mode.
1 FTDI programming port
1 128X64 pixel OLED output port
1 3-pin anti-chop eye port
1 Solenoid output port
1 Battery input port

The board is designed in such a way that the Angel paintball marker can be used with a 9V battery. The installation is simple. JDAM uses the original screw hole locations.

Below is a video of the original development breadboard circuit.
