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.

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.

The Quick Kit is a greatly simplified version of the Raspberry Pi Recovery Kit that [Jay] unleashed on an unsuspecting world late last year. We’ve seen numerous variations on that original design sprout up since then, so we’re very interested to see what the response will be like to this much cheaper and easier to build version.
