Arduino enthusiasts that also enjoy Valves Portal game are sure to be interested in this fan made Portal Sentry Turret which is being created by Steven Gioiosa, was recently signed up for a “Makecourse” class at the University of South Florida.
One of his first projects was to create something that featured both an Arduino micro-controller and 3D printed parts. Using an Arduino Uno connected to an HC-SR04 ultrasonic sensor, and features motion-activated lasers that move back and forth, along with audio feedback, depending on how far away the human target is located.
Check out the demonstration video below to learn more about this interesting build, which has now been published to the Instructables website allowing you to build your very own by following the online instructions.
My project had 3 main requirements:
• The arms pop out
• The turret speaks
• The turret uses a proximity sensor to govern its functioning
This was no easy feat for me, as it was my first time working with pretty nearly all of the technology I’d be using, and I definitely made it harder on myself than it needed to be, but all things considered, I think it turned out pretty well. I wanted this project to be a learning experience, so I tried to use an extremely diverse tool set and approach to making things, just to familiarize myself with all of the different ways you can create things.
If you have the resources, I recommend you save yourself the hassle and 3D print as many of the parts that you can. Keep in mind this project was made over the course of 16 weeks, so I wouldn’t say this is really a weekend project.
