While there is no doubt that the possibilities for better understanding of and more intentional participation in the world around has been greatly enhanced by the invention of the computer, that technology has brought with it its own difficulties. One of those challenges is the very computer itself. Computers are fragile things and they can’t be operated manually…and once it’s broken it’s just an oversized paperweight. We’ve all dropped a laptop or spilled coffee on a keyboard. We’ve all heard the sickening sizzle of improper voltage or gotten ‘the blue screen of death.’ In fact, I once had weeks of work disappear when my laptop underwent the poetically named ‘kernel panic’ – a fantastic name for a punk band if I ever heard one.
What do you do if you know you are going to have to subject this precious and precarious device to some of the most extreme conditions possible? You build a “dirt cheap, tough-as-nails field computer in a Pelican case.” Or at least, that’s what Andrew David Thaler did. Thaler is a deep-sea biologist who engages in a significant amount of fieldwork.
“You’re in the elements, facing wind, rain, and salt spray, sometimes on an open boat far out in the Atlantic. I don’t like going out on the water with my laptop,” he explains. “Losing it would be frustrating and time consuming. It’s tough, but it’s not tough-as-nails. And it’s definitely not cheap. So I tapped into the wealth of Maker experience I’ve accumulated over the last few years and built a new one, using a single board computer, some extra peripherals, and a 3D printer. And I shoved the whole thing into a Pelican case.”
He calls his creation the BeagleBox and it cost him about $200 to build. Compare that to the costs of the field computers used by the military (another group of people with a history of putting laptops through difficult circumstances) and it’s practically free.
“Building a BeagleBox is pretty simple,” Thaler says. “The heart of the machine is a BeagleBone Black, a small, single board computer. You are definitely not going to be blown away by its 1GHz processor, but we’re not building a high-throughput genome analyzer here, we’re building something that can handle the basics and get beat to hell.”
Using the Pelican 1200 case as the model for the outer covering, Thaler designed the shell in preparation for 3D printing. He used a PrintrBot Simple Metal to create his version and has shared the shape files on YouMagine.
“To assemble the shell, I use SciGrip4 acrylic solvent and hot glue, but any adhesive will do. Hot glue seems to take to PLA particularly well. The small tab brackets go on the back of the screen mount, and both hold the frame together and keep the screen in place. The main shells slot into the Pelican case and are helped on with a little bit of hot glue. The USB hub slides through the late rectangular port and the power cord comes out the small semi-circle,” Thaler explains.
Thaler is quick to admit that the creation has drawbacks–but, as my father always says, “You can have anything you want, you just can’t have everything you want.” And, of course, Thaler encourages people to build their own and improve (and share) the design, sharing his experience online. There’s some field data you just can’t get without a computer and this is the machine you want for just those circumstances.
