A 'Portal' Sentry Turret to Guard Your DIY Lab

Inspired by the popular Portal video game franchise, Raxius Bloom, Martin Miller, Ben Pawlowski, and Giovanni Velez decided to create a model turret gun modeled after the ones featured in the game. Within the lore of the game, the turret is advertised as a consumer-grade version of a military defense turret that is intended to be used in the home to protect loved ones. It has the ability to locate, track, follow, and execute commands once a target is found.

The turret operates in four different modes (demo, friendly, sentry, and defective) and will track a target and sound an alarm based on if an intruder is an enemy or not. It is also programmed to speak and play different songs depending on what mode it's in
