While we certainly agree that “Devil Girl From Mars” is an attractive movie title, we have yet to see this apparent British B-movie delight for ourselves. If [Cory Collins]’ fantastic build of Chani, the lumbering, terrifying robot that accompanies the vinyl-clad and caped Devil Girl in question is any indication, we bet it’s delightfully bad.
[Cory] was able to faithfully reproduce Chani — lights, lumbering and all — for less than $50. This price tag does not include the vacuum former required to make the domed head, but hey, it’s an investment into future projects.
[Cory] started by dissecting an R/C stunt car from Harbor Freight and stringing the innards up to a 3D-printed walking mechanism that’s been modified to use gear-reduced motors so it walks more slowly. While Chani is stomping around on TPU treads, the LEDs from the R/C car’s headlights shine inside of its dome. Chani’s boxy body is a big paper sculpture that looks spot-on to us when compared to the movie’s trailer.
We love the way that Chani walks — it sort of dips and glides along in a forward-facing Moonwalk fashion. As you can see in the video below, [Cory] totally nailed the robot’s gait, and it’s hilarious to watch Chani’s little coolant hose-looking arms dangle and shake as he makes his slow and menacing way across the table. Stick around for some scary nighttime footage of Chani against a thunderstorm.
Want your robots to move more like movie robots? All you gotta do is use the right tools.

With the movie Man of War shooting in Cyprus, there was a problem. They needed prop guns that looked realistic and ejected cases when fired, but that were also allowed under the country’s firearm laws. The task fell on [Paradym’s] shoulders, and he set to work producing a prop capable of doing the job.
With the laws in Cyprus, using anything off-the-shelf like an Airsoft pistol was simply not allowed. Instead, he had to start from scratch, creating a design outwardly similar to the Colt 1911 to suit the era of the film. Using green gas canisters for power, the first focus was on getting a realistic semi-automatic firing cycle happening. With that done, the next goal was to get the cases to eject from the weapon on each shot. To achieve this, a lever was used, actuated by the slide moving back after a shot, pushing the “spent” cartridge out of the port.
[Paradym] goes into great deal, covering the design of the 3D printed parts, the machining of springs, as well as the final assembly of the prop. We’ve seen other prop gun builds before, too. Video after the break.

Way back in 1984, the Ghostbusters defended New York City from an onslaught of supernatural phenomena. In their honor, [BALES] created this costume for Halloween, replete with an amazing replica proton pack.
(We know, this is a little late for Halloween 2019, but just think about how early you’re going to be for Halloween 2020!)
While not actually capable of trapping and harnessing entities from the spirit realm, the replica pack nonetheless is impressive. Constructed primarily from EVA foam and PVC pipe, it’s built on a custom built Alice pack frame to make it easy to carry. The cyclotron scores some LEDs, and EL wire completes the neutrino wand. A rough-and-ready paintjob make the gear look well used, and the laser-printed labels go a long way to completing the look.
[BALES] didn’t skimp on the clothing side either. The olive drab overalls, an embroidered patch, and belt were sourced from Amazon, and a custom name badge was produced to complete the ensemble. We’re sure the costume was an absolute hit at Halloween, and gives us plenty ideas of our own. It would pair well with this PKE meter that actually detects radiation, too!
The outlandish computers from 1995’s Hackers are easily one of the most memorable elements of the iconic cult classic. In the film, each machine is customized to reflect the individual hacker that operates it, and feature everything from spray painted camouflage paint schemes to themed boot animations based on the owner’s personal iconography. But what might not be so obvious is that the real-life props took a considerable amount of hardware hacking before they were ready for their big-screen debut.
A group of dedicated Hackers fans have created a website to document, and ideally recreate, all the custom work that went into the various pieces of tech featured in the film. As explained by [Nandemoguy], the group’s latest triumph is a screen-accurate build of Lord Nikon’s laptop. The final product not only looks just like the machine used in the film, but thanks to the internal Raspberry Pi, is far more powerful than the original computer would have been.
Unless you’re on the team over at HackersCurator.com, you might not know that the laptops in the film were handmade chimeras that combined the external cases of various PCs with (usually) the internals of an Apple Powerbook 180c. Why the prop masters of the film would have gone through so much trouble to create the character’s computers is not immediately clear, but if we had to guess, presumably it was due to the requirements of the over-the-top graphical interfaces that are featured so heavily in the film.
At any rate, the replica created by [Nandemoguy] is built in much the same way. At least for the parts you can see on the outside, anyway. He goes through the considerable case modifications required to replace the original keyboard on the Toshiba Satellite T1850 with a Powerbook keyboard, which as you might have guessed, has been converted into a USB HID device with a Teensy microcontroller. He even cuts the ports off the back of the Mac’s motherboard and glues them in place around the backside of the machine. But everything else, including the LCD, is all new hardware. After all, who really wants to go through all that trouble just to have a fancy Powerbook 180c in 2019?
Even if you weren’t a fan of Hackers, the level of detail and effort put into this build it absolutely phenomenal. It’s interesting to see the parallels between this replica and the burgeoning cyberdeck scene; it seems like with a Teensy, a Raspberry Pi, and enough Bondo, anything can be turned into a functional computer.

Fans of Ghostbusters will remember the PKE meter, a winged handheld device capable of detecting supernatural activity. Precious little technical data on the device remains, leaving us unable to replicate its functionality. However, the flashing, spreading wings serve as a strong visual indicator of danger, and [mosivers] decided this would be perfect for a Geiger counter build.
An SBM20 Geiger tube serves as the detection device, hooked up to an Arduino Nano. An OLED display is used to display the numerical data to the user. The enclosure and folding wings are 3D printed, and fitted with 80s-style yellow LEDs as per the original movie prop.
The device is quite intuitive in its use – if the wings flare out and the lights are flashing faster, you’re detecting an increased level of radiation. In a very real sense, it makes using a Geiger counter much more straightforward for the inexperienced or the hearing impaired. Naturally, there’s also a buzzer generating the foreboding clicks as you’d expect, too.
Geiger counters are a popular project, though we hope they don’t become common household items in the near future. Here’s a Fallout-inspired build for fans of the game. Video after the break.

We need to have a talk. As tough a pill as it is to swallow, we have to face that fact that some of the technology promised to us by Hollywood writers and prop makers just isn’t going to come true. We’re never going to have a flux capacitor, actual hoverboards aren’t a real thing, and nobody is going to have sword fights with laser beams.
But just because we can’t have real versions of these devices doesn’t mean we can’t make our own prop versions with a few value-added features, like this cool persistence-of-vision lightsaber. [Luni], better known around these parts as [Bitluni] and for his eponymous YouTube channel where he performs wizardry like turning an ESP32 into a software-defined television station, shows he’s no slouch at more mechanical builds either. The hardware is standard POV fare, with a gyro to sense the position of the lightsaber hilt and an ESP32 to run the long Neopixel strip in the blade. There’s also a LiPo pack and a biggish DC-DC converter; the latter contributes mightily to the look of the prop, with its large heatsinks that stick out from the end of the aluminum tubing hilt. There’s also a small speaker and amp for the requisite sound effects on startup and shutdown, and the position-sensitive thrumming is a nice touch too. Check out the POV action in the video below.
What’s that you say? You recall seeing a real lightsaber here before? Well, sort of, but that’s pushing things a bit. Or perhaps you’ve got this more destructive version in mind.

If you are a follower of the sci-fi horror film genre then it is likely that you will be familiar with the Alien series of movies. Images of Sigourney Weaver bearing a significant amount of firepower, or of John Hurt’s chest being rent asunder by an emerging creature will be brought to mind, it’s one of those franchises which seems to have entered the public consciousness.
With the release of another movie in the series fast approaching, [Keith Elliott] resolved to mark the occasion with his own Alien themed tribute. What, you might ponder, could he choose? Surely there must be plenty of iconic moments in the films that could provide fertile ground for a tribute project!
So presumably after a significant period of reflection, he’s built an Alien themed cuckoo clock. Something of an off-the-wall choice, you might say, but he persevered with it. The main body of the clock is the torso and head of an unfortunate human crew member, the face of the clock is formed by an alien facehugger on his face, and the cuckoo is not a bird in the manner of the Alpine originals, but a chest-bursting alien that issues forth from the torso.
There is a video, which we’ve posted below. Perhaps the chestburster action needs a little more spontaneity and to be a little less rhythmic, but we’ll leave it to you to decide whether it is inspired or merely kitsch.
