I made a Portal turret for my Halloween pumpkin! I was trying to think of things to carve: vampire Android? R2-D2? Zoidberg? Then I thought: I could do a character from Portal 2! I was going to carve something like GLaDOS or Wheatley, but then I realized that a portal turret would be perfect:

To make the glowing red eye, I punched a small hole in the pumpkin, taped an LED to a battery, and pushed the LED from the center of the pumpkin through the small hole. I thought about doing an actual red laser, but 1) I don’t want to blind any kids walking by my pumpkin, and 2) laser beams aren’t visible unless there’s fog or smoke or something for the beam to hit.

To make the side “gun” sections of the pumpkin, I had a small dowel rod lying around, so I just cut two small stakes from the dowel rod and jammed them into the pumpkin sides. It’s a bit rickety, but it works. For the video, I played some turret sound effects and moved my red laser over the pumpkin as if another turret was locking onto it.

I didn’t want to take long to carve my pumpkin. I finished it in maybe an hour, but check out this really elaborate pumpkin that someone else did. And it turns out that they work at Google too!

I like how my pumpkin came out overall:

Happy Halloween, and I hope you’re getting creative with your pumpkin carving!
