BeagleBox 2: A cheap, tough, field computer in a Pelican Case by Andrew_Thaler

Last crawled date: 3 years ago

Last year, as part of Oceanography for Everyone, we debuted the BeagleBox, a small, cheap, tough, basic field computer powered by a BeagleBone Black. The first BeagleBox didn’t promise much, it was designed for basic field work and, most importantly, to be cheap enough that researchers wouldn’t be worried about damaging it. It wasn’t designed to be your only computer but to replace your more valuable computer when participating in fieldwork.
In the last year, the single board computer landscape has changed, with new systems running off tiny, powerful 64bit ARM chips. One of the first of this new breed of SCBs to hit the market was the massively Kickstarted and rocky-launching Pine64.
The BeagleBox has been redesigned around these slightly larger SCBs, with a more robust, easier to assemble case.
The case now has it’s own inputs and outputs, so you can plug into power, internet, USB, and audio without getting into the guts. As with the original, it’s been built specifically to handle 12V DC at relatively high amperage, so you can plug it directly into a car outlet, clip to an outboard motor battery, plug into any wall outlet with the right AC/DC adapter, or hook up to a stand alone battery pack with the right output. The Pine64 can be swapped with any board that takes 5V DC and has an HDMI video out without making any changes to the set up.
Why is this preferable to a cheap computer, like the Chromebook? Well, for starters, it’s probably cheaper, depending on where you source your parts. The Pine64 starts at $15, way below anything comparable on the market. The screen and battery are the only other major investments. It’s customizable. You can build it to your specific needs.
Because it’s modular, you can swap parts out as needed. When a Chromebook breaks, you’re basically stuck buying a new Chromebook. With the BeagleBox 2, you just swap out the bad component. It’s already housed. When working on a boat, you don’t need to be extra cautious transferring gear or personal, don’t need to panic when it rains, don’t need to double check your backpack when you take the inevitable mud-fueled spill into the marsh. When the case is closed, the system is waterproof in one of the toughest field boxes on the market.
On top of that, it’s just cool. I’m looking forward to rolling up to my next conference and busting out a laptop printed into a Pelican case.

We named the first BeagleBox after the BeagleBone Black used to power it. Obviously the new system no longer uses what is still my favorite SCB, so we’re just going to declare that all future iterations of the BeagleBox are named for the HMS Beagle, in honor of one of the greatest field biologists of all time.
