Quivering Facehugger Is All Geared Up

December 30, 2023 by 4 Comments

[Jason Winfield] shared with us a video describing a project with a lot of personality: a mounted, lit, and quivering Alien facehugger triggered by motion. The end result is a delightful jump scare, and the Raspberry Pi that controls everything also captures people’s reactions.

It starts with a little twitch when motion is sensed, then launches into a perfectly unsettling quiver combined with light and sound. We particularly like the wave-like effect from the LED lighting, which calls to mind illumination from rotating hazard beacons.

The unit looks like a mounted and tastefully-lit static model, but is actually primed to sense motion.

One challenge was how to efficiently move the legs. Rather than use a motor for each limb, [Jason] settled on a single motor driving a rotating cam arrangement. You can see the results for yourself in the video below, but getting there was not simple.

The surplus motor [Jason] chose is thin and high-torque, but runs extremely fast. Since he wanted the legs to quiver creepily rather than vibrate, something needed to be done to mitigate this.

The solution is a planetary gear assembly that drives a rotating ring and cam arrangement coupled to the facehugger’s legs. There’s only one motor, but the effect is that each leg’s motion is independent of the others. The whole assembly is quite slim, and everything is contained within the frame.

Facehuggers and gear assemblies are not exactly an everyday combination, but believe it or not this isn’t the first time the two have joined forces. Check out the Aliens-themed cuckoo clock, complete with crew member torso and emerging chestburster!

Sci Fi UI Made Easy With Arwes

June 29, 2023 by 18 Comments

Many of us grew up watching Star Trek, marvelling at the beautiful colorful interfaces on the computers that ran the Starship Enterprise. Today’s computer interfaces have certainly grown fancier since the Windows 3.1 and Mac System 7 days, but they’re still nowhere near that gorgeous. The Arwes framework aims to change that, at least where web apps are concerned.

The framework is inspired by the cyberprep and synthwave aesthetics, while drawing from media like TRON: Legacy and Halo. You can get a peek at what it can do on the Arwes website, or look at how it runs on sites like SoulExtract or the Cyber Movie Database. It’s very much about glowing lines, 1980s computer sounds, and screens with animated text fills.

It’s still in an alpha release, and likely isn’t yet ready for business-critical production use. It currently consists of a set of basic components that can be assembled into a functional futuristic website design, but you’ll need some experience to use the tools at hand. There’s a sandbox for experimenting that should help in that regard.

You might just find that it’s the perfect tool to create an interface for your very own cyberdeck, or you might put it to work on your next website design. Either way, if you create something fantastic, don’t hesitate to drop us a line.

 

A More Conspicuous Computer Assistant

June 25, 2023 by 11 Comments

Back in the last century, especially in the ’40s to the ’60s, one of the major home decor trends was to install various home appliances, like the television or stereo, into its own piece of furniture. These were usually bulky, awkward, and incredibly heavy. And, since real life inspires art, most of the futuristic sci-fi technology we saw in movies and TV of the time was similarly conspicuous and physical. Not so with modern technology, though, where the trend now is to hide it out of the way and forget it exists. But [dermbrian] wanted some of his modern technology to have some of the mid-century visibility aesthetic so he made some modifications to his Amazon Echo.

The Echo itself remains largely unmodified, other than placing it inside a much larger cookie tin with some supporting electronics. For that, [dermbrian] found a relay board with a built-in microphone which switches the relay off when it detects sound so that when the Echo is activated, the sound from its speaker activates the module. From there it drives a series of blinkenlights which mimic the 60s computer aesthetic. Some custom fabrication and light diffusion methods were needed to get it to look just right, and a switch on the outside can disable the mechanism if it is getting triggered by background noise like music from his stereo.

While the appeal of this style may be lost on anyone who wasn’t a fan of the original Lost in Space, Star Trek, or Jetsons, it certainly holds a special significance for those who grew up in that era. It’s certainly not the first project we’ve seen to take a look back at the aesthetics of bygone eras, either. Take a look at this project which adds lenses to modern displays to give them the impression of antiquated CRT displays.

PC Hardware Monitor Uses Tricorder-Derived Tech

August 8, 2022 by 17 Comments

The visually striking hardware monitor that [Mangy_Dog] recently put together for his new custom PC build might look like something out of the Alien franchise, but the hardware he’s built it around actually comes from a very different science-fiction property: Star Trek. Or at least, from a very impressive line of Star Trek props, anyway.

Given the incredible amount of time and effort that [Mangy_Dog] has put into developing his Star Trek: Voyager tricorder, it’s no surprise that he would decide to reuse its graphics chip and microcontroller. But while the familiar hardware might have helped jump-start this build, this was no weekend project.

He’s steadily been working on it for several months now, and even entered it into the 2022 Sci-Fi Contest back in April. Obviously he wasn’t able to complete it before the Contest deadline, but looking at the final results, we’re happy to see he kept chugging away at it.

Of course, with a project like this, the hardware is only half the battle. In the video below, [Mangy_Dog] explains the challenges involved in creating not only the firmware that runs on the monitor, but the accompanying PC-side application. This included modifying existing libraries to add support for the device’s unique flash storage arrangement, and pulling the relevant system status information out of the operating system and into a series of customizable widgets.

As impressive as the project is, [Mangy_Dog] says he’s not done yet. A second revision of the hardware and software will address several issues and add new capabilities, and considering the high degree of polish we’ve come to expect from his creations, we’re not surprised

2022 Sci-Fi Contest: The Winners Are In

April 28, 2022 by 4 Comments

The Sci-Fi Contest closed out on Monday, and we put our heads together and picked our favorites. And it was no easy task, because in addition to many of the projects simply looking stellar, many went all-out on the documentation as well, making these stellar examples that we can all learn from, whether you’re into sci-fi or not. But who are we kidding? From the responses we got, you are.

The Winners

[RubenFixit]’s Star Trek Shuttle Console is a Trek themed escape room in a box. The project’s extraordinary attention to detail and exhaustive project logs absolutely won our judges heart. From the LCARS graphics to the 3D printed isolinear chip bays and mimetic crystals, it’s all there. [Ruben] estimates about 300 hours of work went into this one, and it shows.

We had no shortage of robotic projects in the contest, but [RudyAramayo]’s R.O.B. won our judges over. This one is not a joke, weighing in at over 140 lbs of custom metalwork and righteous treads. It’s also made out of some expensive hardware all around, so maybe this isn’t your weekend-build robot. We love the comment on the Arduino test code suite: “For gods sake man, you must test your code when it becomes an autonomous vehicle.”

Finally, [zapwizard]’s Functional Razor Crest Control Lever is a prop and a video game controller in one. We can totally see Grogu playing with this, and we were wowed by the attention to detail in the physical build — with custom gears and a speed limiter — as well as the attention to prop-making detail. Some parts are custom-cut stainless steel plates. 3D printed parts are covered in aluminum tape and chemically aged. Awesome. Oh yeah, it’s also a working USB joystick.

These three winners will be receiving a $150 shopping spree at Digi-Key.

2022 Sci-Fi Contest: The Animatronic Baby Yoda You’ve Always Wanted

April 19, 2022 by 2 Comments
Simple robot parts make up the internals.

When it comes to sci-fi, it’s hard to go past Star Wars, and many submissions to our contest land in that exact universe. [Kevin Harrington]’s entry is one such example, with his animatronic Baby Yoda that’s exactly as cute as you’d hope it would be.  

The build is based on a Pololu Romi chassis, a simple two-wheeled differential-drive robot platform. It’s paired with a robot arm in the form of Hephaestus Arm 2, which provides the articulation for the precocious little creature. An ESP32 microcontroller serves as the brains of the operation, controlling all the servos and motors that make baby Yoda move. Control is via WiFi, using a website hosted on the ESP32 via RBE1001lib.

The animatronic baby Yoda would surely be a hit sitting on one’s shoulder at any sci-fi convention. Overall, it’s a simple robot that becomes more personable by skinning it with an adorable toy. It’s not the first baby Yoda (or Grogu) that we’ve seen, either – the popular character has inspired builds before, too! Video after the break.

Announcing: The 2022 Hackaday.io Sci-Fi Contest

March 10, 2022 by 6 Comments

Ladies and Gentlemen, Sentient robots, Travellers from the distant future, or Aliens from the outer rim, it’s time to enter the 2022 Hackaday.io Sci-Fi Contest!

We last ran the Sci-Fi contest in the far, far past — before the Voigt-Kampff machine was detecting replicants on the gritty streets of 2019’s LA. Back then, we had some out-of-this-world entries. It’s time for the sequel.

Thanks to Digi-Key, the contest’s sponsor, your best blaster, your coolest costume, or your most righteous robot could win you one of three $150 shopping sprees in their parts warehouse. Create a Hackaday.io project, enter it in the contest, and you’re set. You might as well do that right now, but the contest closes on April 25th.

Sci-Fi is all about the looks, so if it’s purely decorative, be sure to blind us with science (fiction). If your project actually functions, so much the better! Of course we’d like to know how it works and how you made it, so documentation of the project is the other big scoring category. Whatever it is, it’s got to be sci-fi, and it’s got to have some electronics in it.

If you’re looking for inspiration, you could do a lot worse than to check out [Jerome Kelty]’s Animatronic Stargate Helmet, that not coincidentally took the grand prize last time around. It’s an artistic and engineering masterpiece all rolled into one, and the description of how it’s made is just as extensive. [Jochen Alt]’s “Paul” robot isn’t out of any particular sci-fi franchise that we know, but of rolling on one ball and reciting robot poetry, it absolutely should be.

Honorable Mentions

In addition to the overall prizes, we’ll be recognizing the best projects in the following honorable mention categories:

  • Star Star: Whether you’re “beam me up” or “use the force”, fans of either of the “Star” franchises are eligible for this honorable mention.
  • ExoSuit: This category recognizes sci-fi creations that you can wear. Costumes and armor fit in here.
  • Stolen off the Set: If your blaster looks exactly like Han Solo’s, you’re a winner here.  This is the category for your best prop replica.
  • Living in the Future: If your sci-fi device was purely fantasy when imagined, but now it’s realizable, you’re living in the future. A working tricorder or a functioning robot companion would fit in fine here.
  • The Most Important Device: Has no function, but it certainly looks like it does. Just blinking lights that blink back and forth, yet the government spent millions of dollars on it.

You don’t have to tell us where your project fits in. We’ve got you covered.

Engage!

Get started now by creating a project page on Hackaday.io. In the left sidebar of your project page, use the “Submit Project To” button to enter in the 2022 Sci-Fi Contest.

You have from now until April 25, 2022 to get it finished. Of course, if your time machine actually works, you can finish it whenever. Check out the Hackaday.io contest page for all the fine print.
