Arduino Motorized SMT Solder Paste Dispenser

This is a motorized solder paste dispenser for soldering SMT boards that was inspired by this thing http://www.thingiverse.com/thing:384680. The home directory of this project is on github here https://github.com/zapta/misc/tree/master/paste_injector and it include hardware and firmware design of a compatible controller board that is Arduino compatible (it looks to the Arduino IDE as an Arduino Pro Mini).
