Foam Board, Old Electronics, And Imagination Make Movie Magic

December 31, 2019 by Dan Maloney 11 Comments

When it comes to building sets and props for movies and TV, it’s so easy to get science fiction wrong – particularly with low-budget productions. It must be tempting for the set department to fall back on the “get a bunch of stuff and paint it silver” model, which can make for a tedious experience for the technically savvy in the audience.

But low-budget does not necessarily mean low production values if the right people are involved. Take [Joel Hartlaub]’s recent work building sets for a crowdfunded sci-fi film called Infinitus. It’s a post-apocalyptic story that needed an underground bunker with a Fallout vibe to it, and [Joel] jumped at the chance to hack the sets together. Using mainly vintage electronic gear and foam insulation boards CNC-routed into convincing panels, he built nicely detailed control consoles for the bunker. A voice communicator was built from an old tube-type table radio case with some seven-segment displays, and the chassis of an old LCD projector made a convincing portable computer terminal. The nicest hack was for the control panel of the airlock door. That used an old TDD, or telecommunications device for the deaf. With a keyboard and a VFD display, it fit right into the feel of the set. But [Joel] went the extra mile to make it a practical piece, by recording the modulated tones from the acoustic coupler and playing them back, to make it look as if a message was coming in. The airlock door looks great too.

Like many hacks, it’s pretty impressive what you can accomplish with a deep junk pile and a little imagination. But if you’ve got a bigger budget and you need some computer displays created, we know just the person for the job.

Warwalking For Radiation

September 10, 2019 by Elliot Williams 24 Comments

Can’t find a recently updated survey of radioactivity in your neighborhood? Try [Hunter Long]’s DIY scintillation counter warwalking rig. (Video also embedded below.) What looks like a paint can with a BNC cable leading to an unassuming grey box is actually a complete kit for radiation surveying.

Inside the metal paint can is a scintillation counter, which works by attaching something that produces light when struck by ionizing radiation on the end of a photomultiplier tube, to make even the faintest hits “visible”. And the BNC cable leads to a Raspberry Pi, touch screen, GPS, and the high-voltage converters needed to make the photomultiplier do its thing.

The result is a sensitive radiation detector that logs GPS coordinates and counts per second as [Hunter] takes it out for a stroll. Spoilers: he discovers that some local blacktop is a little bit radioactive, and even finds a real “hot spot”. Who knows what else is out there? With a rig like this, making a radiation map of your local environment is a literal walk in the park.

[Hunter] got his inspiration for the paint-can detector from this old build by [David Prutchi], which used a civil-defense Geiger counter as its source of high voltage. If you don’t have a CD Geiger detector lying around, [Alex Lungu]’s entry into the Hackaday Prize builds a scintillation detector from scratch.

Hacking Shelters And Swimming Pools

July 18, 2019 by Al Williams 44 Comments

How would you survive in a war-torn country, where bombs could potentially fall from the sky with only very short notice? And what if the bomb in question were The Bomb — a nuclear weapon? This concern is thankfully distant for most of us, but it wasn’t always so. Only 75 years ago, bombs were raining down on England, and until much more recently the threat of global thermonuclear war was encouraging school kids to “duck and cover”. How do you protect people in these situations?

The answers, naturally, depend on the conditions at hand. In Britain before the war, money was scarce and many houses didn’t have basements or yards that were large enough to build a family-sized bomb shelter in, and they had to improvise. In Cold War America, building bomb shelters ended up as a boon for the swimming pool construction industry. In both cases, bomb shelters proved to be a test of engineering ingenuity and DIY gumption, attempting to save lives in the face of difficult-to-quantify danger from above.

Fallout Inspired Display Is Ready For The Apocalypse

May 18, 2019 by Tom Nardi 9 Comments

We’ve seen more projects based on books, TV shows, movies, and video games than we could ever hope to count. Hackers and makers derive inspiration from what they see around them, and it turns out there’s considerable overlap between the folks who sit in their labs building stuff all day and the ones who spend their free time playing games or watching movies. Big surprise, right? But among them, few can match the influence of the Fallout franchise.

As the latest entry in a long line of incredible Fallout-inspired builds, we present the Octoglow VFD by [Michał Słomkowski]. While this build isn’t trying to replicate anything directly from the games, it captures all the hallmarks that make up the game’s distinctive post-apocalyptic chic : antiquated vintage components, exposed internals, and above all, a dirty, industrial look. It’s supposed to look like somebody built the stuff out of parts they found in the trash, primarily because that’s exactly what they would’ve needed to do.

So what is it? Well, that’s a little hard to nail down. Frankly we’d say it’s a little more like art than anything, but it does have some useful functions. Currently it shows the time, date, weather information, and various RSS feeds on its dual vacuum fluorescent displays. There’s also a real-life Geiger-Müller counter onboard, because what says Fallout more than a little radiation?

The build itself is absolutely fascinating, and [Michał] leaves no stone unturned in his comprehensive write-up. Every module of the Octoglow has its own page on his site, and each one is bristling with hardware details, schematics, and firmware documentation. Reading along you’ll run into all sorts of interesting side notes: like how he reverse engineered a wireless temperature sensor with his sound card, or devised his own ten-pin bus to interconnect all the modules.

If the Octoglow doesn’t quite scratch that Vault-Tec itch, there’s plenty more where that came from. How about this replica of the wall terminals from Fallout 4, or this radiation monitor perfect for roaming the wastelands? Don’t forget to bring along this 3D printed Thirst Zapper for protection.

Fallout Watch Build Triumphs In Adverse Conditions

September 27, 2018 by Lewin Day 3 Comments

Is it a badge? Is it a watch? Well, it’s [Sarif’s] take on a wrist-mounted computer from the Fallout series, so you’re free to choose your own designation! We think the Brotherhood of Steel would be proud to have this piece of kit.

[Sarif] commenced the build after first getting their feet wet with the pipman, a watch inspired by Metro 2033 and Steins;;gate as much as Bethesda’s popular post-apocalyptic RPG. It features all the fruit – GPS, compass, a TV-B-Gone – and perhaps the coolest feature, long-since-deprecated bubble LED displays and flippy switches for that Altair-esque charm.

The build log is full of details, from the components used and the debugging battles involved in the journey. [Sarif] learned about using transistors, burning up a few along the way – some say setting the lab on fire is the quickest way to learn important lessons, anyway. On top of that, there were some software niggles but in the end, the watchputer made it to DEFCON 26 anyway!

Builds like this that start from limited experience and go deep into the trials and tribulations involved are an excellent way to learn about what goes into the average DIY electronics project, particularly when talking about embedded systems. And if you’re keen to check out the work of [Sarif’s] contemporaries, we’ve got a collection of all the awesome badges from DEFCON 26. Enjoy!

Fully 3D Printed Nerf Thirst Zapper

February 24, 2018 by Tom Nardi 6 Comments

In case you weren’t aware, there is a whole community out there that revolves around customizing NERF guns. In that community is a subculture that builds their own NERF guns, and within that group is a sub-subculture that 3D prints NERF guns. So next time you are contemplating how esoteric your little corner of the hacking world is, keep that in mind.

Anyway, [Wekster] is currently making his way in the world of 3D printed one-off NERF guns, and has unveiled his latest creation: a fully 3D printed “Thirst Zapper” from Fallout 4. Except for the springs, each and every piece of this gun was printed on his CR-10 printer. You could even wind your own springs if you really wanted to, and keep the whole thing in-house. Because if you’re going to do something this niche, you might as well go all in.

Even if you aren’t a member of the NERF-elite, the video [Wekster] has put together for this project is a fantastic look at what it takes to design, print, and finish a custom build. From creating the model to mixing the paint to match the in-game model, this video has a little something for everyone.

This isn’t the first time we’ve covered 3D printed NERF guns, but it’s surely the most ornate we’ve ever seen. Interestingly, the bar is set pretty high for Fallout-themed builds in general, so perhaps there’s some unwritten rule out there in regards to Fallout prop builds.

Global Thermonuclear War: Tweeted

October 8, 2017 by Al Williams 22 Comments

[Andreas Spiess] did a video earlier this year about fallout shelters. So it makes sense now he’s interested in having a Geiger counter connected to the network. He married a prefabricated counter with an ESP32. If it were just that simple, it wouldn’t be very remarkable, but [Andreas] also reverse-engineered the schematic for the counter and discusses the theory of operation, too. You can see the full video, below.

We often think we don’t need a network-connected soldering iron or toaster. However, if you have a radiological event, getting a cell phone alert might actually be useful. Of course, if that event was the start of World War III, you probably aren’t going to get the warning, but a reactor gas release or something similar would probably make this worth the $50.
