Portal Radio Is Why Valve Needs To Build Hardware

We’ve seen Portal gun builds, a few cute turret replicas, and even a miniaturized version of GLaDOS, but [John]‘s Portal radio replica is the first physical version of this oft-forgotten Portal item.

Interestingly, the entire radio is made from scrap. The spheroid body shell is made from the foam insulation from a commercial freezer, carefully sculpted, Bondoed, and painted over the course of 300 hours. The radio guts are taken from an upcycled radio, and powered by either an internal battery or a wall wart DC adapter – perfect for carrying around a test chamber with a portal gun.

Right now, there’s an AM/FM receiver inside the radio along with an audio input so an iPod or such can be plugged in. While we would have loved to see a loop of theuptempo version Still Alive, we’re guessing [John] hasn’t found an easy way to do that with junked parts yet.

Check out [John]‘s build video after the break.

    1. It can be done easier,using a limited range RF Transmitter/Receiver,when you are at a certain areas the Receiver will pick up the signal and trigger a Relay which can trigger an Mp3 Player with the Portal Transmissions and turn on another LED that will light RED.

    1. If I had GLaDOS breathing down my neck to make them perfect, I’d spend that time too. After all we all know what she does to things/people she is displeased with. No fun tube ride to the incinerator in Brians future ;)

      Or he could have 3d printed a shell in about 4.

      Your move, 3D printers.

    3. Hey there. It took that time because i was experimenting on how it can be done accurately,regardless if i knew my way around on Sculpturing on Foam. My second try took 2 Noons,and my third a little bit more but it looks better than my first (the one you see in this video),maybe i’ll put a video up aswell soon,you can subscribe so you wont miss it.

  1. I have the Still Alive (Looping Radio Mix) song set as my phone’s ringtone. Now I have difficulty playing Portal because I stop and try to answer my phone when I get near one of those radios. I don’t need that happening in real life too!

    1. Hello. This is actually what i wanted to do in the first place. I have a circuit from another radio that can migrate to a Portal one,but maybe in a later model,as of the three radios i’ve made,two have an Aperture Logo,and one has the typical 85.2Fm.
