Build your own Portal turret in 150 easy steps

If there were a contest for the most thorough step-by-step project log [Kurt] would the champion. He recently a posted 150 step build log for his fleece-covered Portal turret project. If you can get over the need to click-through 30 pages of steps, there’s a lot to like about this project.

First, what it doesn’t do: The Turret doesn’t split up the middle and fire bullets at you. This is a relief, but the fact that it’s not lethal doesn’t mean it just sits there looking interesting. It can detect movement, it knows when you pick it up, and it can tell when it’s been knocked over. All of these interactive sensory inputs are used to playback various sound bytes from the Portal games, making it a great piece of desk art for those working in geek-centric offices. See for yourself in the video after the break.

The body itself is a food storage container which houses the barebones Arduino and Adafruit Wav shield. As near as we can tell, a PIR sensor detects movement, and leaf switches on the legs tell it when it’s been picked up or tipped over. But we only made a cursor examination of the assembly steps so we might be missing something.

If you’re not into the turrets, maybe this potato is more up your alley.

    Funny – when I read “The body itself is a food storage container” I thought, hey great, put cake in there and when a coworker comes to get it, this fires up, but alas, only the components are in the food container.

    You messed up the tag

    yoUtube

    not yotube

    this turret does not function nearly enough like the original turret in the game. should be called “fuzzy white thing with an LED ring” or FWTWALR

    yo, tube!

    Lol, 150 easy steps

    Love the software, but the hardware… leaves something to be desired in terms of sheer destructive power and cold-heartless machine qualities. Someone make one out of metal with a real gun attached =]

    Got to love this level of documentation. I am pretty sure I can build this following his instructions. This kind of attention to detail in the write up will land you a pretty sweet job when you graduate GT.

    I am not sure how I feel about a plush portal turret. I am tempted to build one, just because there is so much detail. But of course with a few minor changes.

    Aperture would never make these out of fabric or metal, but maybe depleted uranium, moon rocks and the sort of plastic toys are made from.

    Damn it i hoped it would be hosted on instructables :P

    With all these Portal projects, it’s a winder noone tries selling them all. This’d be a great project for Kickstarter.

    They already sell automated sentry guns that have military grade targeting at http://www.turretsentry.com/
