3D Printed Portal Turret Searches And Destroys

Portal Turret Prop

Ah yes, Portal — one of the most iconic puzzle games from this past decade by Valve. [Yvo] just put the finishing touches on his fully 3D printed, working, Portal Turret. Well — it doesn’t have guns — but it does just about everything else!

This intricate prop replica has attention to detail written all over it. [Yvo's] carefully designed it to actuate as close to the video game model as possible. Its eye and arms move, has a targeting laser and even features a camera for color based object tracking. You can also play around with it using a joystick — but it’s much more fun to leave on autonomous mode.

Because the whole thing is 3D printed, [Yvo] has also made up an Instructable for making your own, and according to him, it’s not that hard to build! This isn’t his first rodeo either, if you remember the awesome GlaDOS we shared last year — that’s his too.

Sci-Fi Contest Roundup: The Valve Universe

653px-Source_engine_logo_and_wordmark.svg

While most of the entries to our Sci-Fi contest come from movies and TV shows, a select few are based on the Valve universe, including a few builds based on Portal and Team Fortress 2.

Deadly neurotoxinGLADOS

Who wouldn’t want a gigantic articulated sociopathic robot hanging around? Two groups are building a clone of GLaDOs from the Portal series. and already the builds look really great.

[AmarOk], developed an open-source personal assistant called RORI that intends to be a more helpful version of GLaDOs, without all the testing and killing. He, along with [Peterb0y] and [n0m1s] are turning this personal assistant software into a GLaDOs replica.

Taking a slightly different tack, [Eric] and [jjyacovelli] built a GLaDOs-like robot with a camera in the ‘face’. This camera connects to a Google Glass and tracks the user’s head movements. There’s also a Nerf gun attached to the end of the robot body, triggered by double winking. Yep, it’s a heads-up display GLaDOs, perfect for punishing your test subjects.

Heavy load comin’ through!

Sentry

Not to be out done by a malevolent, hyper-intelligent artificial intelligence, [Tyler] and [Ryan] are building the cutest gat’ dern weapon in all of west Texas. It’s the level one sentry from Team Fortress 2, and the guys are turning one into a paintball sentry.

The TF2 sentry is a cute little bugger capable of motion tracking and perimeter defense, filling enemies with lead should they ever come too close.

While the end result probably won’t be as large or as heavy as the “official” real-life turret, a smaller table-top sized model is probably a little more practical. Even if it doesn’t live up to expectations, upgrading the sentry is simply a matter of whacking it with a wrench a few times.

 

There’s still time for you to cobble together an awesome Sci-Fi project and have a chance to win some awesome prizes.

Sci-Fi Contest: Source Universe Roundup

sci-fi-contest-universe-roundup

The Hackaday Sci-Fi contest has 36 entries so far. Since there are fifteen prizes available, you stand an excellent chance of winning; but you can’t win if you don’t play. It’s pretty easy to be considered for the contest. You simply need to hack together something Sci-Fi related and show off your work. Head over to the contest page and check out the details. Ten of the prizes are popularity-based, so posting early is the best bet! For those that were put-off by the team requirement, there’s a hack to get around that.

Since this is a themed contest we thought we’d give you an update on where inspiration is coming from. Below is the break-down of each Sci-Fi universe that has been so-far adopted by the entrants. We’d like to point out that this isn’t limited to movies, as the bulk of inspiration is to be found in literature. Why don’t we get a comment thread going here to help brain-storm for people who want help locking onto an idea?

Oh, and if you’re wondering about the banner images. These were taken from three of the contest projects. The upper left is a GLaDOS replica controlled by Google Glass (complete with Nerf dart gun) inspired by Portal. Bottom left is a pair of Peril-Sensitive sunglasses inspired by A Hitchhiker’s Guide to the Galaxy. And the bottom right is a life-sign scanner inpired by Stargate Atlantis.

SoundCube: A Companion Cube that can Talk

sound_companionCube

The Enrichment Center likely disapproves of the SoundCube: a portal music box in the form of a Portal Companion Cube. [Andreas] finished this project a couple of years ago, but we’re glad he’s finally had time to give a rundown on the details at his blog.

The build is primarily a modified speaker box cube—constructed out of what appears to be MDF—with four Alpine SXE-1725S speakers placed at the center of the middle faces. The faces were routed out to resembled the Companion Cube, while the electronics mount and the speaker grills were 3d printed. Inside is a homemade amplifier built around an Arduino Mega, with a TDA7560 quad bridge amplifier, a TDA7318 audio processor, a Belkin bluetooth receiver, and a 3.5″ touchscreen for volume control and for input selections.

Two 12v 7.2Ah lead-acid batteries keep the cube functional for an entire weekend of partying, but probably add a few pounds to the already hefty MDF construction. Check out [Andreas's] blog for more pictures and his GitHub for all the necessary code.

Can you believe this Portal gun was built from scratch?

This Portal gun will really make [aNoodleJMC's] costume pop this year. He actually built the video game weapon replica from scratch. It even includes some electronics to light it up blue or orange depending on which portal he’s planning to fire at an available flat surface.

There’s a lot of parts that went into the project, but by far our favorite one on the list is an acrylic toilet plunger. Its handle serves as a light pipe for the colored LEDs and can be seen above as a cloudy rod at the center of the clear barrel. A 4″ and 3″ PVC pipe helped to form the rest of the barrel, along with a 3″ clear acrylic pipe for the transparent areas. The bulbous parts of the body were sculpted from florist’s foam. Once he had all of the parts roughed out it’s obvious that [aNoodleJMC] spent a ton of time filling problem areas with Bondo, sanding everything smooth, and giving it a paint job he can be proud of. We hope he didn’t forget to include GLaDOS in the fun.

We actually just bought our Portal gun. But that’s because we had the big plans of adding the ability to levitate objects.

Hackaday’s portal gun actually levitates a companion cube

I was out to lunch with a couple friends, brainstorming ideas for fun projects when one of them says “Wouldn’t it be cool if we could build a working gravity gun?”. We all immediately concurred that while it would in fact be cool, it is also a silly proposition. However, only a few seconds later, I realized we could do a display piece that emulated this concept very easily. Floating magnetic globes have been around for quite some time.

I determined I would tear the guts out of a stock floating globe and mount it on a portal gun, since they’re easier to find than a gravity gun. I would also build a custom companion cube to be the correct size and weight necessary.

Portal gag-video

These guys make your own video editing chops look just plain sad. They put together a video demonstrating the portal gun in real life.

Unleashing the beast

We have this problem all the time. The noise regulations were preventing [Massimiliano Rivetti] from letting the true voice of his Ferrari be heard. He hacked into the control system and can now adjust it via iPhone to roar with power. [Thanks Claudio via openPicus]

Music so bad you want to throw something

Here’s a novel way to include the worker bees in music selection around the office. A piezo element was attached to the back of a framed poster and when you throw something at it, the next track is played. We really loved the demo video for this one. [Thanks Calum via DontBelieveTheHype]

Acrylic frame for a CNC machine

[Jake] wrote in to show off his progress on a CNC build. He’s got a frame made of acrylic and some other materials. It’s not up and running yet, but what he’s got so far looks very nice.

Helo built for one

All we can think with this one-man helicopter is failure of those propellers. At least with an ultralight plane you can glide to a gentler crash-landing. [Thanks Filespace]
