PA-I

PA-1

Status: Completed, destroyed, and recycled (2007)

This is the first in the PA Design series of coil guns and my start in electronics. Statistics are based on projectile drop vs. distance traveled. The design was a week long project and was made with very little knowledge of electronics. It has since been destroyed and recycled into the subsequent coilguns. And yes, that’s a Whataburger straw.
