Portal mini golf hole will incinerate your ball…you monster


One of [Tom’s] friends is celebrating a birthday soon, and he was asked to make a mini golf hole for the event. While most people would expect to bring beer or guac to the shindig, he saw this as an opportunity to bring a little bit of Portal to life.

Near the end of the first Portal game, you are forced to pitch your companion cube into the incinerator, a scene which [Tom] thought would be the perfect mini golf hole. He started out by building an iris door mechanism, which he surrounded with chicken wire and some plaster, producing a fantastic-looking waste disposal pipe.

He added a ramp that leads up to the hole, then [Tom] got busy with the electronics portion of the fixture. Once the portal button at the end of the ramp is pressed, an Arduno triggers a pair of motors to open the waste disposal door and fire up a smoke machine. The result, as you can see in the video below, is nothing short of awesome.

[Tom] says he’s in the process of building a pair of turrets and a working golf ball portal as well, so if you’re a big Portal fan, be sure to check out his site for updates.

    the “bring a little bit of Portal to life” links to a questionable porn site

    “Near the end of the first Portal game”
    Don’t you incinerate companion cube like within the first quarter of the game? Nowhere even near the end.

    He’s running wordpress 3.3.1 which has exploits.

    Last line in the html states:
    Proudly powered by my hatred of the internet and all that use it

    Guessing the porn site is related.

    Oh and very cool build!! :)

    What, no propane and forced air incineration system? Here I thought this was a clever way to end a game of mini golf.

    This was a triumph.

    So, being this is for a birthday party and all, will there be cake if you make the shot?

    Why not expand this to have the golfball roll into an orange portal and have a bit of electronics dispense another golf ball out of a blue portal somewhere else in the course? You could use a powerful solenoid to fire it out with the same force it went in at. Just thinking aloud.

    Forget that, I didn’t see the reference earlier. Reading are hard.

    I’m sure it will be a great source of amusement. As a concept, portal fits into crazy golf really neatly, because of the puzzle solving aspect and the comical slapstick element. I’ll look forward to seeing your finished project in full :)
