Learn how to build your own Overwatch prop blaster with this multi-part guide! This 3D printed prop gun will include lights, sound effects, and background music, all played through a 20 watt amp and four speakers.

In part 1 we'll design the electronic functions and overall circuit design, and then build the individual functions as working prototypes. 

In later parts in this series we'll combine the parts into a single system, planning how it will all fit by using a cardboard prototype, and ultimately create a 3D printed prop gun.
