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, [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.

Dragon Doors Round Off Hobbit Themed Restaurant

[Abhimanyu Kumar] is renovating a hotel in Nainital, near the India-Nepal border, and like any self-respecting Lord of the Rings fan, he wanted to give the restaurant a Hobbit theme. He built circular windows and to top it off a gorgeous round door complete with dragon hinges.

I asked him how well the doors work, as the 50kg (over 110lbs) weight of each of the doors must put a lot of strain on the hinges. [Abhimanyu] told me, “The door opens quite smoothly.While building the hinges even I was concerned about needing support as all other commercially available hinges we tried broke down or got bent.”

However, once the dragon hinge was installed it worked better that we expected and the door stays about 0.5″ over the ground at all times. The dragon hinges (made from 1/4-inch iron) integrate the hinge pins to the wings of the dragon, making it look like they are taking off when the doors open.

He has posted plenty of pictures of the build and the final product looks incredible.  The tail of the dragon is quite long and provides a lot of support for the entire door. Each hinge itself weighs about 30kg, so it should be strong enough to hold up a door for a long time without any sagging. Kudos to him for some serious engineering!

A Raspberry Pi Garage Door Opener

We can never seem to get enough garage door hacks around here. [Tanner’s] project is the most recent entry into this category. He’s managed to hook up a Raspberry Pi to his garage door opener. This greatly extends his range to… well anywhere with an Internet connection.

His hack is relatively simple. He started with the garage door opener remote. He removed the momentary switch that was normally used to active the door. He bridged the electrical connection to create a circuit that was always closed. This meant that as long as the remote had power, the switch would be activated. Now all [Tanner] had to do was remove the battery and hook up the power connectors to his Raspberry Pi. Since the remote works on 3.3V and draws little current, he is able to power the remote directly from the Pi. The Pi just has to turn its pin high momentarily to activate the remote.

The ability to toggle the state of your garage door from anywhere in the world also comes with paranoia. [Tanner] wanted to be able to tell if the door is up, down, or stopped somewhere in the middle while he was away from home. He also wanted to use as little equipment as possible. Since he already had an IP camera in the garage, he decided to use computer vision to do the detection.

He printed off two large, black shapes onto ordinary white computer paper. One was taped to the top of the door and one to the bottom. A custom script runs on the Pi that grabs the latest image from the camera and uses OpenCV to detect the shapes. If both shapes are visible, then the script can assume the door is closed. Otherwise, it’s likely open. This makes it easier for [Tanner] to know if the door is opened or closed without having to check the camera himself.

Can’t get enough garage door hacks? Try these on for size. Continue reading “A Raspberry Pi Garage Door Opener”

Secret Attic Library Door

We have a pretty good guess where [Krizbleen] hides away any seasonal presents for his family: behind his shiny new secret library door. An experienced woodworker, [Krizbleen] was in the process of finishing the attic in his home when he decided to take advantage of the chimney’s otherwise annoying placement in front of his soon-to-be office. He built a false wall in front of the central chimney obstacle and placed a TV in the middle of the wall (directly in front of the chimney) flanked on either side by a bookcase.

If you touch the secret book or knock out the secret sequence, however, the right-side bookcase slides gently out of the way to reveal [Krizbleen’s] home office. Behind the scenes, a heavy duty linear actuator pushes or pulls the door as necessary, onto which [Krizbleen] expertly mounted the bookcase with some 2″ caster wheels. The actuator expects +24V or -24V to send it moving in one of its two directions, so the Arduino Uno needed a couple of relays to handle the voltage difference.

The effort spent here was immense, but the result is seamless. After borrowing a knock-detection script and hooking up a secondary access button concealed in a book, [Krizbleen] had the secret door he’d always wanted: albeit maybe a bit slow to open and close. You can see a video of its operation below.

Capacitive Garage Door Opener Hides Behind Your Dash

[Pyrow] wanted to upgrade his garage door opener remote. It worked just fine, but changing those tiny batteries out can be an inconvenience. Plus, the remote control was taking up valuable storage space and would always rattle around while driving. [Pyrow] decided to make use of an Omron E2K-F10MC2 capacitive touch sensor to fix these issues.

[Pyrow’s] circuit still makes use of the original remote control. He just added some of his own components to get it to do what he wanted. The circuit is powered by the car’s battery, so it never needs a battery replacement. The circuit is protected with a fuse and the power is regulated to prevent electrical spikes from burning up the original remote control. The actual circuit is pretty simple and uses mostly discrete components. It’s all soldered onto proto board to keep it together. He only had to solder to three places on the original remote control in order to provide power and simulate a button press.

Next, [Pyrow] took his dash apart. He used double-sided tape to attach the touch sensor to the back of the dash.  After securing the electronics in place with tape, he now has a working hidden garage door opener. Full schematics are available in the writeup linked above. Also, be sure to watch the demonstration video below.

The PebblyPi: A Smart Doorbell


A Pebble smart watch, and a Raspberry Pi. They are a perfect match. This is probably what [Daniel] thought when he embarked upon his latest project, a smart doorbell called the PebblyPi (tip submitted by [Ben]).

The actual project is quite easy to implement. All you need really need is a Raspberry Pi, a switch, a resistor, and a Pebble Smart Watch (plus a smart phone). Using a simple Python script on the Raspberry Pi, button press notifications are sent to Pushover, which allows the notification to arrive on your smart phone (and thus your Pebble Smart Watch). Pushover is a very cool notification service for Android devices, iPhones, iPads, and your Desktop. The concept behind this project is great, and the fact that it is so simple to implement opens up many other possibilities for interfacing your home electronics with the Pebble Smart Watch (or even just your smart phone). The ability to create custom notifications on any of your devices using any internet connected system is amazing!

You could receive notifications from your absurdly accurate weather station, or even your soil moisture monitor. Have you used Pushover in any of your projects? The possibilities are endless!

Halloween Doorknocker Decoration Hack


If you’re new to hacking, Halloween is a great excuse to get started, and [Chuck] has put together an inexpensive animated Halloween decoration that you can show off on your front door. After scoring a $5 plastic Halloween doorknocker from Wal-Mart, [Chuck] gathered together a small pile of components and then set about breathing some life (death?) into its scary but motionless face.

Though he opted to use a Digispark, you should be able to use any Arduino that is small enough to stuff inside the plastic head. [Chuck] cut some holes in the eyeballs and glued in two RGB LEDs, then cobbled together a quick-and-dirty mount in the mouth area to hold a small servo. The lights and the servo are wired to the Digispark, which turns the lights on and instructs the servo to slam the ring against the door. It’s is battery powered and currently has only two settings: on or off. This should be good enough to scare the kids for this year, but [Chuck] has plans to add a much-needed motion sensor and sound via a Bluetooth connection. 

As simple as this build is, it could be just the thing to get you in the holiday spirit, or to introduce the young hacker in your home to the world of electronics and coding. Check out the short video of the doorknocker after the break, then swing by [Chuck’s] website for detailed build instructions and his Github for the source code. If you’re having trouble finding this doorknocker at Wal-Mart, [Chuck] recommends a similar one on Amazon. Don’t stop now! Make some Flickering Pumpkins too, or if you want a challenge, hack together your very own Pepper’s Ghost illusion.
