fix 1 - voltage limited on system for safe operation of system and not enough to burn laser coils, also can handle a really big voltage spike without ruining component and laser coils.
fix 2 - switch fix (puppetzio )sp) fix rev 2. short one of the switches to avoid any timing irregularities that could cause a crash.
fix 3 - pending , will act as a watch dog (much like the matrix pic fix, but revised and improved) will possibly be adding leds or using the existing reset/power leds to do some cool things like blinking with a crash interupt etc.
