The BeagleBox 2
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 (particularly grad students) wouldn’t be too 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 SCB to hit the market was the massively Kickstarted, and rocky-launching Pine64. I received my 1GB Pine64 late last week, and immediately set to work redesigning the BeagleBox to house this larger board (and correct for some other annoyances in the original design). So here it is, an even beefier, cheaper, tougher field machine.
Yes, it will run an OpenROV. It will not run it well.
3D Printing. No new technology in the last decade has been heralded with as much hope and hyperbole as the promise of desktop replicators fabricating whatever object you need at the push of a button. 3D printing has made huge steps forward, with more sophisticated machines at lower prices, new materials that vastly expand the printer’s capabilities, and the breathless optimism that foresees a printer in every home, as mundane and easy to operate as a conventional printer*.

And yet, for all the hype, most personal 3D printers are pressed into service fabricating plastic tschotskes — low quality, low function items of little to no utility. While the raw potential of 3D printing continues to expand, the promise of personal printers seems mired in the sandbox: an expensive toy for grownups. A toy that produces heaps of plastic detritus that will eventually find it’s way into the environment.
I posit here that, while it is true the the vast majority of people currently have no practical need for a 3D printer, under the right circumstances, a personal 3D printer can be an incredibly useful tool in the modern home.
A little over a year ago, we bought a personal 3D printer. It’s a Printrbot Simple Metal, a tough, no nonsense machine that works as well in my home office as it does at sea. Its footprint is small, and it can handle object up to 150 mm by 150 mm by 150 mm. Not huge, but big enough to be useful. And yes, this printer has primarily been used to fabricate parts for Oceanography for Everyone and other scientific endeavors. You can read more about that here: A 3D-printable, drone and ROV-mountable, water sampler and Oceanography for Everyone: Empowering researchers, educators, and citizen scientists through open-source hardware. I’m not talking about the scientific utility of the printer, but rather, how it fits into our homestead.
From simple sand dollars to life-sized hammerhead shark skulls, 3D printable ocean objects present an incredible opportunity for ocean outreach. Many commercial biological models are expensive, fragile, and often overkill for educators’ needs, where simple, robust, and easily replaceable anatomical models suffice. Over the last year, I’ve been honing my 3D printing skills, learning how to design 3D-printable objects, and mastering 3D scanning using free software and the now-ubiquitous smartphone. My designs, along with the open-source objects used for Oceanography for Everyone, can be found on my YouMagine profile (though Patreon supporters get early access to most prints).
Earlier this year, I wrote about how the ability to essentially photocopy a three dimensional object in a matter of hours revived my Ocean Optimism and opened up a whole new world of outreach possibilities. Since then, I’ve been working behind the scenes on some bigger projects that depend on 3D printing, one of which, Oceanography for Everyone launched last month. It’s a big ocean out there, and one person can’t possibly come close to producing a comprehensive collection of ocean objects. With several successful 3D scans under my belt, I think it’s time to share the process and invite the rest of the ocean-loving world join me in my efforts to scan the sea.
123D Catch, the software that powers it all.
Last week, we launched a novel little experiment in crowdfunding marine science and conservation – Buy David Shiffman a Less Ugly Pair of Sunglasses – ostensibly about replacing David’s legendarily hideous sunglasses with something a bit more aesthetic. Of course, anyone digging into the stretch goals quickly realized that this was less about sunglasses and more about funding some cool research and outreach projects we’re currently working on; projects like a hammerhead conservation genetics analysis, building a marine ecology drone, and sending students from underserved schools of a shark tagging trip. This was made more explicit when we hit our first goal in the first 36 hours of funding.
With the first funding goal achieved, I decided we needed a cool perk, something not particularly expensive to produce but completely novel and cool enough to justify making a heftier donation. And, of course, it needed to be thematically related to the spirit of the project.
Enter the Megalodon.
