Hardware

This is probably the only time I'll ever use my Electrical Engineering degree outside school. Scott already talked about the slick OS design. Here are some hardware details:

• The "lasers" are IR (infrared) LEDS, which are picked up by IR receivers. Para Light Corp were kind enough to provide us with high power IRLEDs that have ranges of up to 100m!
• The main display is a HD44780 LCD module, which is supported natively by Arduino.
• Normal LEDs everywhere for sexiness, muzzle flashes, and ... well sexiness.
• An optional discrete laser pointer attachment as a laser sight.
• A few more buttons and switches complete the build.

Pretty simple. The trick is fitting all that into each different shell design.
