Easy DIY Portal Companion Cube Pendant Lamp

DIY Portal Companion Cube Lamp

More of a geek hack than a DIY, this is a quick five-minute project for Portal fans. And even in lamp form, the companion cube will not threaten to stab you. And, in fact, cannot speak.

In the event that the Companion Cube does speak, we urge you to disregard its advice. πŸ™‚ Oh GLaDOS (and Portal), we love you.

Anyway, this is easy. First things first – go orderΒ THIS companion cube box from ThinkGeek. It’s generally on sale for $6. If you are anti-that for some reason, then you can definitely make your own with white posterboard and paint. We went lazy on this one, since our last project (hi, Claptrap!) was pretty time consuming. The only other thing you’ll need is a pendant lamp kit. We got ours at IKEA for $8, which included an energy efficient bulb that will apparently last pretty much forever.

Let’s assume you just ordered the box. We’ll fast-forward a few days, and it just arrived. Fun. Here’s what you do to make it into a DIY Portal companion cube lamp.

Your supply list

Cut the bottom off, including the flappy things.

Trace the base of the cord kit onto the top of the box. Cut it out. You also need to cut a hole in the flappy things underneath (you’ll see what we mean when you make yours).

Put the cord in the hole you cut on top, screw in a lightbulb. Like we said, this is really easy.

Hang it up. Turn it on. Done!

We like the soft glow it gives. The interior of the box is black, which we considered painting gold/silver/white, but we ended up liking it just the way it is.

On a different note, a quick reminder that we recently joined Twitter and Facebook! (in addition to Pinterest – which is still our favorite –Β Instagram, and Tumblr). Pick your poison.

    Nice. The thing I love more than anything about reading your blog is that it inspires me to do all sorts of things (including, but not limited to, finishing the projects I have in the works). The portal cube is such an iconic piece of art, and I love the idea of having it as a light!

    Oh. My. Goodness.

    I think you just made my day because this project means I can make Mr. Dude’s day. He LOVES Portal – it’s his favorite puzzle game – and he may or may not have the lifesize replica Portal Gun and display stand … along with companion cube ice cubes and warning sign coasters.

    He may just have a new light above his desk in the near future …
