Let’s imagine that you’ve spent most of your life indoors tinkering with electronic gadgets and that you don’t have a lot of practical survival experience. Since you’re currently reading Hackaday, it shouldn’t be much of a stretch for you. Let’s further imagine that our entire civilization gets upended by an ecological disaster, nuclear war, invaders from Zeta Reticuli, that sort of thing. What do you do?
If you’re [Evan Meaney], you might start by retrieving the Crash Recovery Device from its EMP shielded storage nook. This mobile digital library is designed to serve as a backup copy of all the information we’d lose in a post-Internet world. It holds detailed geological maps, a library of survival manuals, agriculture guides, and should you get bored, the entirety of Wikipedia.
Of course, having all that information in a digital format is no good if you can’t access it. Rather than designing a device from scratch, [Evan] based his rugged command center on the Raspberry Pi Recovery Kit by [Jay Doscher].
He deleted the more esoteric components such as the mil-spec connectors on the front panel, and improved the ability to switch between different power sources with a capacitor bank big enough to smooth out any momentary interruptions. There’s also added circuitry so the device can be run on a wider range of voltages, allowing the use of whatever batteries or power sources can be scrounged up. [Evan] even thought to use automotive style fuses that could be pilfered from abandoned vehicles if necessary.
We know what you’re probably thinking; a better way to hone your survival skills and prepare for a disaster would be to just go camping a few times a year. Fair enough. But if you’re a city dweller who might not have the option, it’s hard to argue that you wouldn’t be better off having a mobile repository of survival information to consult should you need it. Doubly so if it looks this cool.

If civilization goes sideways and you need to survive, what are the bare essentials that should go in your bunker? Food and fresh water, sure. Maybe something to barter with in case things go full on The Postman. That’s all sensible enough, but how’s that stuff going to help you get a LAN party going? If you’re anything like [Jay Doscher], you’ll make sure there’s a ruggedized Raspberry Pi system with a self-contained network with you when the bombs drop.
Or at least, it certainly looks the part. He’s managed to design the entire project so it doesn’t require drilling holes through the Pelican case that serves as the enclosure, meaning it’s about as well sealed up as a piece of electronics can possibly be. The whole system could be fully submerged in water and come out bone dry on the inside, and with no internal moving parts, it should be largely immune to drops and shocks.
But we imagine [Jay] won’t actually need to wait for nuclear winter before he gets some use out of this gorgeous mobile setup. With the Pi’s GPIO broken out to dual military-style panel mount connectors on the front, a real mechanical keyboard, and an integrated five port Ethernet switch, you won’t have any trouble getting legitimate work done with this machine; even if the closest you ever get to a post-apocalyptic hellscape is the garage with the heat off. We especially like the 3D printed front panel with integrated labels, which is a great tip that frankly we don’t see nearly enough of.
This is actually an evolved version of the Raspberry Pi Field Unit (RPFU) that [Jay] built back in 2015. He tells us that he wanted to update the design to demonstrate his personal growth as a hacker and maker over the last few years, and judging by the final product, we think it’s safe to say he’s on the right path.
Raspberry Pis are great for tons of projects, but if you want to use them outside, you’re going to need a waterproof enclosure. Not happy with what was available, [Jay Doscher] went all out and created the Raspberry Pi Field Unit — a piece of tech that looks straight out of the Call of Duty franchise.
Wanting it to be extra durable, [Jay] started with a Pelican Case 1300 — the standard in electronics protection. These come with a Pelican panel mount, so he had some plastic laser cut specifically to fit the panel mount, and attach all of his components. Speaking of components, he got only the best — inside is:
- A Raspberry Pi 2 with a few PIHATs (permanent prototyping shield)
- A 10.1″ IPS display
- A high power wireless USB dongle
- Weather proof USB and LAN connectors
- An RTC for when it’s off the network
- A 12V power supply for running off solar panels
- DC-to-DC adapters to bring it down to 5V
- A whole bunch of hardware from McMaster-Carr
