Fallout 4 Gets Logic Gates, Is Functionally Complete

Fallout logic. This is literally called Fallout logic. This is far more confusing than it should be.

Fallout 4, the latest tale of post-apocalyptic tale of wasteland wanderers, got its latest DLC yesterday. This add-on, Contraptions Workshop, adds new objects and parts to Fallout 4‘s settlement-building workshop mechanic. This add-on brings more building pieces, elevators, and most importantly logic gates to Commonwealth settlements.

The Fallout logic gates are used in conjunction with electric generators, lights, and automated sentries used to build settlements. Although a simple NAND would do, there are several types of logic gates including AND, OR, XOR, NOT, NAND, NOR, and XNOR.

The in-game explanation for these gates is very, very weird. AND, OR, and XOR “transmit power or not depending on the combination of power to their inputs”. NOT, NAND, NOR, and XNOR are apparently different, “only transmitting power if their inputs are connected directly to the output of other logic gates”. The reason for this arbitrary distinction between different sets of gates is currently unknown except to a few programmers and project leaders at Bethesda. It should be noted {AND, OR, XOR} is not functionally complete.

With implementations of logic gates in video games comes some very interesting if useless applications. Already Fallout 4 has light boxes, allowing for huge animated billboardsFallout speakers, the wasteland’s equivalent of Minecraft’s note block, can be used to play simple melodies. You can do anything with a NAND, so we would expect automated, sequenced versions of animated billboards and monophonic synthesizers to appear in short order.

Functional completeness can add a lot to a game. Since Minecraft added redstone logic to the game, we’ve seen some very, very impressive block-based builds. The Minecraft CPU generally regarded as being the first, most complete CPU took about three months to design and build. This build didn’t use later additions to the redstone toolbox like repeaters, pistons, and the now-cheaty command blocks.

Pip Boys As A Service

A few weeks ago Fallout 4 was released, and like all future games of the year, productivity has fallen through the floor, cosplayers are busy crafting outfits, and modders are busy tearing the game to pieces. As with all big game releases, Fallout 4 has a super-deluxe, ultra-collectible edition, and this version comes with its own Pip Boy, the in-game wrist-mounted user interface that manages stats, inventory, and quests.

This Pip Boy is actually functional, relying on a smartphone to mirror the display in-game Pip Boy. This, of course, means there must be some sort of communication between the game and a phone. [Kyle] found this somewhat interesting and decided to dig into these communications to see what else could be done with the real life mirror of the in-game Pip Boy

With a simple swipe of nmap, [Kyle] discovered two ports open on his PS4. By creating a relay to listen in on whatever is passing through these ports, [Kyle] built a tool that allows anyone to dump data from the in-game Pip Boy to any other service.

The library and command line tool work with PS4 and PC and are able to dump stats and data from the in-game Pip Boy to the outside world. It will be interesting to see what kind of mashups could be created with this; especially interesting would be a leaderboard for an entire office of vault dwellers, but a TV-sized Pip Boy would also suffice.

Yes, that is a challenge.

Dealing with Fallout

In just a few short days, Fallout 4 will be released and a substantial portion of the Hackaday staff will be taking the day off. As you would expect, a lot of people with 3D printers, soldering irons, and far too much time on their hands are getting pumped for the Fallout release. Here’s a few Fallout builds we’ve found over the past few weeks:


919501417186321280The most iconic thing you’ll find in a Fallout game is the Pip-Boy, the UI for the player and a neat wrist-mounted computer (that somehow has a CRT in it, I guess) for the player’s character. Hackaday’s own [Will Sweatman] built his own Pip-Boy 3000 that’s completely functional. The build uses a 4.3 inch touch display, a 10 position rotary switch, and a bunch of 3D printed parts.

Elsewhere on Hackaday.io, [Karl] is working on a functional Pip-Boy controller for Fallout, and [cody] built one with a Raspberry Pi. Of course, if you’re super special and have two thousand dollars to blow, Bethesda released a limited-edition Pip-Boy edition of Fallout 4 that’s compatible with most cell phones.

The Not Pip-Boys


There’s more to Fallout than just wrist-mounted computers, and for the true aficionados, there are gigantic gear-shaped doors. [TreyHill] has a partially finished basement with a gaming room tucked behind his very own vault door. The door itself is built out of plywood and rolls along a gear rack mounted to the floor. Will it hold up to a nuclear blast? Probably not. Is it up to code? It looks cool, at least.

[Lilykill] on Thingiverse is extremely capable with a copy of solidworks and produced a bunch of 3D models from the Fallout universe that includes power armorray guns, more Pip-Boys, plasma grenades, and a Nuka-Cola truck.

Fallout 4 for the Apple II

Fallout 4 will be available for the PS4, Xbox One, and PC, leaving out a large contingent of retro gamers. Fear not, lovers of the 6502: there’s’ a version for the Apple II:

This tribute to both the Apple II and Fallout was made with the Outlaw Editor, an SDK for pseudo-3D game development on exceedingly old hardware. There’s actual ray casting happening in this tribute, and it works just the same as Wolfenstein 3D or the like.

The First PipBoy We’ll See This Year

You heard that we’re shutting down Hackaday on November 11, 2015, right? That’s the release of Fallout 4, and trust me: I’m not getting anything done that day.  A new game in the Fallout series means more power armor cosplay builds, and hundreds of different wearable electronics from the friendly folks at Vault-Tec. I speak of the PipBoy, the wrist-mounted computer of the Fallout series, and [THEMCV] built the first one we’ll see this year. It won’t be the last.

The PipBoy [THEMCV] created is the 3000a model, the same one found in Fallout 3 and New Vegas. We’ve seen a few real-live versions of the PipBoy before; this one used the PipBoy prop that came with the Amazon exclusive special edition of Fallout 3. Things have changed in the years since the release of Fallout 3, and  to build his PipBoy, [THEMCV] just bought one from Shapeways.

The electronics consist of a Raspberry Pi Model A, 3.5″ LCD, a battery pack, and a great piece of software to emulate the software of the PipBoy 3000. It looks great, but [THEMCV] still needs to find a few retrofuturistic buttons and dials to complete the PipBoy experience.
