Recreating the Radio from Portal

If you’ve played Valve’s masterpiece Portal, there’s probably plenty of details that stick in your mind even a decade after its release. The song at the end, GLaDOS, “The cake is a lie”, and so on. Part of the reason people are still talking about Portal after all these years is because of the imaginative world building that went into it. One of these little nuggets of creativity has stuck with [Alexander Isakov] long enough that it became his personal mission to bring it into the real world. No, it wasn’t the iconic “portal gun” or even one of the oft-quoted robotic turrets. It’s that little clock that plays a jingle when you first start the game.

Alright, so perhaps it isn’t the part of the game that we would be obsessed with turning into a real-life object. But for whatever reason, [Alexander] simply had to have that radio. Of course, being the 21st century and all his version isn’t actually a radio, it’s a Bluetooth speaker. Though he did go through the trouble of adding a fake display showing the same frequency as the one in-game was tuned to.

The model he created of the Portal radio in Fusion 360 is very well done, and available on MyMiniFactory for anyone who might wish to create their own Aperture Science-themed home decor. Though fair warning, due to its size it does consume around 1 kg of plastic for all of the printed parts.

For the internal Bluetooth speaker, [Alexander] used a model which he got for free after eating three packages of potato chips. That sounds about the best possible way to source your components, and if anyone knows other ways we can eat snack food and have electronics sent to our door, please let us know. Even if you don’t have the same eat-for-gear promotion running in your neck of the woods, it looks like adapting the model to a different speaker shouldn’t be too difficult. There’s certainly enough space inside, at least.

Over the years we’ve seen some very impressive Portal builds, going all the way back to the infamous levitating portal gun [Caleb Kraft] built in 2012. Yes, we’ve even seen somebody do the radio before. At this point it’s probably safe to say that Valve can add “Create cultural touchstone” to their one-sheet.

Echo Dot Finds Swanky New Home In Art Deco Speaker

The phrase “They don’t make them like they used to” is perhaps best exemplified by two types of products: cars and consumer electronics. Sure, the vehicles and gadgets we have now are so advanced that they may as well be classified as science-fiction when compared to their predecessors, but what about that style. Our modern hardware can rarely hold a candle to the kind of gear you used to be able to buy out of the “Sears, Roebuck and Company” catalog.

So when [Democracity] came into possession of a wickedly retro art deco speaker, it’s no surprise he saw it as a perfect opportunity to bring some of that old school style into the 21st century by rebuilding it with an Amazon Echo Dot at its core. The fact that the original device was a speaker and not a full radio made the conversion much easier, and will have everyone trolling yard sales for months trying to find a donor speaker to build their own.

To start the process, [Democracity] popped the panels off and ripped out what was left of the speaker’s paper cone and coil. In a stroke of luck, the opening where the driver used to go was nearly the perfect size to nestle in the Echo Dot. With a 3D printed cradle he found on Thingiverse and a liberal application of epoxy, the Dot could get snapped into the speaker like it was always meant to be there.

[Democracity] then picked up some absolutely gorgeous speaker cloth on eBay and hot glued it to the inside of the panels. What was presumably the volume knob was pulled out of the bottom and turned out to be a perfect place to run the Dot’s USB cable out of.

A lesser man would have called this project completed, but [Democracity] knows that no hack is truly complete without the addition of multicolored blinking LEDs. With the RGB LED strips installed inside, the light is diffused through the cloth panels and creates a pleasing subtle effect. You can almost imagine a couple of vacuum tubes glowing away inside there. Judging by the final product, it’s no surprise [Democracity] has a fair bit of experience dragging audio equipment kicking and screaming into the modern era.

This isn’t the first time we’ve seen an old piece of audio equipment get a high-tech transfusion, and isn’t even the first time we’ve seen the Dot used to do it. But it’s certainly the one we’d most like to see sitting on our shelf.

Holman is Your Phone’s Best Friend

Let’s get something straight right up front: this isn’t much of an electronics project. But it is a very artistic 3D printing project that contains some electronics. [Sjowett] used an off-the-shelf class D amplifier with BlueTooth input to create a simple BlueTooth speaker with a subwoofer. As you can see from the pictures, woofer is exactly the term to use, too.

The clever mechanical design uses 3D printing and common metric PVC pipe. That’s a great technique and resulted in a very clean and professional-looking build. If you don’t have easy access to metric pipe, you could print the pipes, but it will take longer and might not look quite as good.
