HPA FDL-3 with Narfduino, Select Fire, and software controlled core pressure

I had a Super Core lying about collecting dust, but I really felt in the mood to build myself a new FDL-3... The problem is that FDL's are flywheelers, and to be honest, I already have 4 of them.. And so what would any self respecting Nerfer do in my position? Mod. And mod I did... It has the following features: - Narfduino with OLED console - Software controlled air pressure (i.e. turn the dial for more or less power) - Variable FPS configured separately for Auto and Burst - Select fire - Semi-auto, burst, full auto, binary trigger, and ramped (you map the modes you want to the buttons in the config screen) and a range of configuration options for each - Dual profile settings - Ammo counter with reset on mag change - Tournament lock to cap the maximum air pressure - Auto jam detection / air out, and battery protection - Open-bolt configuration - Spectre composite barrel and acetal scar
