At Hackaday, the projects we cover are generally a one-off sort of thing. Somebody makes something, they post it online, we share it with our audience — rinse and repeat. If a project really captures people’s imaginations, it might even inspire a copy or two, which is gratifying for everyone involved. But on the rarest of occasions, we run across a project like [Jay Doscher]’s Recovery Kit.
To say that the Recovery Kit was an inspiration to others would be putting it mildly. Revolutionary would be more like it, as it resulted in more “Pi-in-a-Pelican” builds than we could possibly count. So it’s only natural that [Jay] would return to the well and produce a second version of his heavy-duty cyberdeck.
Over the last couple of years, we’ve seen a wave of impressive rugged mobile computing devices based on the ubiquitous Raspberry Pi. Sometimes they involve repurposing an existing heavy duty enclosure, and in others the Pi takes up residence in a 3D printed case which may or may not be as strong as it appears. In either event, they usually don’t lend themselves to duplication because of the time and expense involved in tracking down or printing all the parts required.
But the Raspberry Pi Quick Kit by [Jay Doscher] may change that. It represents what must surely be the simplest and fastest route to a building a rugged mobile ARM computer for your hacking adventures. Beyond the Pelican 1150 case that serves as the outer enclosure, you only need three printed parts and a handful of fasteners to complete the build. Of course you’ll need a Raspberry Pi and the official touch screen as well, but that’s sort of a given.
Electronics mounted to the 3D printed frame.
All of the electronics mount onto the three piece 3D printed frame, which is then press-fit into the opening of the Pelican case. Since you don’t need to pop any holes through the case itself, the assembled unit remains water and air tight. While [Jay] has recently shown off a very impressive 3D printed Pi enclosure, there’s really no beating a legitimate heavy duty storage case if you’re trying to protect the hardware.
When you want to use the Pi, just open the case and plug your power and accessories into the panel mount connectors under the display. There’s no integrated battery or keyboard on this build, but considering how small it is, that shouldn’t really come as a surprise.
[Jay] is targeting the Pi 4 for the Quick Kit, so that means WiFi and Bluetooth will come standard without the need for any external hardware. It looks like there might just be enough room to include an RTL-SDR receiver inside the case as well, but you’ll need to do a little redesigning of the 3D printed parts. If you do modify this design to pack in a few new tricks, we’d love to hear about it.
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.
