Installing GLaDOS in the ceiling of your house

glados-ceiling-light

Install this light fixture in your bedroom and you might kiss your nights of peaceful sleep goodbye. Fans of the Portal game franchise will recognize it as a smaller version of the megalomaniacal artificial intelligence character from the game. This particular rendition is how she looked in the second installment of the series. The lamp is the creation of [Dragonator]. It was entirely 3D printed before being outfitted with LEDs to actually function as a light.

Our first thought is that this project is all about 3D design to get the final product t0 look so fantastic. But if you dig a little deeper you’ll see that it’s so much more than that. To get pieces that look this fantastic you must have a well tuned printer and be willing to let it run for 40-60 hours as it burns through 2 kg of filament. At that point you’re still far from the finish line as the [Dragonator] then set to work sanding and painting all of the pieces. From there he lovingly assembled everything, including gears and motors to give it motion.

In the end the electronics did not work as he envisioned. But maybe after a bit of time off from all that work he’ll revisit the project and make a bit more progress. For us, the aesthetic already makes the hack. Making it move and sound like the character would be over the top.

If you liked this you can’t miss the GLaDOS potato.

The only thing he needs now is a micro and RTC

For [Dino]‘s 44th Hack A Week extravaganza, he made powered window blinds in five minutes. It’s a simple build with a small gear motor and a bit of tubing to adapt the shaft to the control rod of the blinds. Good job [Dino].

The wonderful [Lizzie] over at LUSTlab realized that typing meta keys really slows down the development process. The result? Foot pedals for the Shift and Command keys. No build log for this one, but it’s just a set of old racing pedals and a disused keyboard.

So much cooler than a potato

[mdevaev] out of Russia built a fully articulated GLaDOS replica. Here’s the build album and the relevant MLP forum post. This GLaDOS is tiny – probably less than a foot long, but it moves around and speaks (Russian, which is weird). Somebody get us a couple of motorcycle fenders so we can build the 1:1 scale version.

Visualizing a plane of fog

[greg] was looking for a way to visualize the chaotic turbulence of air. He mounted a laser on a computer fan and held some dry ice above the beam. The result looks like it could make for an interesting photography project, but check out the video if you don’t believe us.

We were asking for it

We asked for battery charging circuits that don’t use specialized parts. [Petr] found this one that only uses few transistors, a MOSFET and a voltage regulator. In one of the Hackaday comments, [atomsoft] had the idea of putting a USB plug on the traces to save a bit in component costs. [mohonri] said he designed one, but we have yet to see it. Perhaps next links post…

This GLaDOS potato is a lie

Why settle for virtual reality when you can make the digital world into reality? [Josh] wanted to have a GLaDOS potato accompany him through life when not playing Portal 2. He set to work to see what kind of replica prop he could come up with. Judging from the image above, and demo video after the break, he nailed it right in the spud.

There’s no worrying about rot. The potato and a few parts were molded from Sculpey and baked in the oven. Since the fake spud is hollow in the center it’s easy to hide the bits that make it talk. An old MP3 player was loaded with quotes from the game, and plays them back via an LM386 audio amplifier circuit and a speaker hidden below the electronic eye. The eye is lit by five yellow LEDs which are also tied into the amplifier to make them blink and fade with the intensity of the audio signal.

A paint job and the nails and wire really make the build look just right. Now [Josh] needs to host a geek-themed Halloween party so he can really show this off.
