As the Hack A Day crew notes, the talented Maker also increased the voltage flowing to the gun’s motor, as well as the overall strength of the Vulcan by replacing a 2kg spring with a 5kg spring.
Meanwhile, targets are tracked with a webcam via Processing and some code from Project Sentry Gun. Of course, individuals wearing an Instructables t-shirt will be spared the otherwise inevitable barrage of plastic darts.
Additional key specs include:
- Servo for the turn axis: BMS-660DMG+HS
- Servo for the tilt axis: Hitec HS-805BB
- TIP120 transistor
- 1N4004 diode
- 1k resistor
- Pin header
- 6 Volt battery pack
- 5 kg replacement spring for the Vulcan
- Optional: Paint and plastic primer for the gun
- 3 mm lead pearls or something similar as a counter weight
- 6V 3700mAh battery pack
- 9.6V 2000mAh battery pack
