Built to Last: A Reflection on Environmentally Conscientious Woodworking

Built to Last: A Reflection on  Environmentally Conscientious Woodworking
Built to Last, Conservation

I make things. I make weird electronic things. I make scientific instrument things. And I make things out of wood. I make a lot of things out of wood. 

When I’m not working on marine conservation technology, educational programming, or high seas policy, I’m usually out back in the woodshop, building furniture, functional art, and other woodcrafts. This probably isn’t a surprise. For the last eleven years, one of the most popular articles at Southern Fried Science has been How to build a canoe from scratch on a graduate student stipend. 

Every few years, I turn an analytical eye on my hobbies, assessing the lifecycle of the materials I use, the sources of inefficiency, and, most importantly, how the practice of the craft aligns with or deviates from my personal environmental ethic. In other words, I do a sustainability audit on my recreational activities. For the last year, I’ve focused on understanding and improving the environmental impacts of my woodworking.

I built a horrifying cyborg sea turtle hatchling so you can learn a little bit about behavioral ecology

Science

Sea turtles, in case you didn’t know, are pretty great. These giant marine reptiles have been chilling out in the ocean for over 100 million years, largely unchanged. But their evolutionary foray onto land along with the rest of the tetrapods (a move largely regarded as a mistake by most extant species) left them with one one critical vulnerability: they have to return to land to lay their eggs, and their hatchlings must survive a grueling march to the sea within minutes of emerging into the world.

To find their way back to the sea, sea turtle hatchlings emerge from their nests in the darkness and track light cues on the horizon, tracking the glow of starlight on waves. This becomes a huge problem when the beach is littered with the pollution of artificial lights, leading hatchlings away from the sea and towards streets, resorts, and beachfront bars. Light pollution is such a serious problem for sea turtle survival, that many municipalities which host turtle nesting beaches ban the use of superfluous lighting during nesting season. 

Protecting sea turtle nests and nesting sea turtles, particularly the massive, primordial leatherback sea turtle, is a core mission of the Dominica Sea Turtle Conservation Organization (DomSetCO). Leatherbacks are exceptionally sensitive to light. On the top of their heads is a translucent patch of skin directly above the pineal gland. This window to the turtle’s brain serves as a rudimentary third eye which can sense how light changes.

You can help support DomSetCO by donating to our campaign to build the Rosalie Conservation Center, a hybrid rum distillery, fish hatchery, and conservation center in Dominica. Drink rum, save turtles.

I built a head-mounted LiDAR array that lets you see the world like a dolphin via vibrations sent through your jaw.

I’m Andrew Thaler and I build weird things.

Last month, while traveling to Kuching for Make for the Planet Borneo, I had an idea for the next strange ocean education project: what if we could use bone-conducting headphones to “see” the world like a dolphin might through echolocation?

Bone-conducting headphones use speakers or tiny motors to send vibrations directly into the bone of you skull. This works surprisingly well for listening to music or amplifying voices without obstructing the ear. The first time you try it, it’s an odd experience. Though you hear the sound just fine, it doesn’t feel like it’s coming through your ears. Bone conduction has been used for a while now in hearing aids as well as military- and industrial-grade communications systems, but the tech has recently cropped up in sports headphones for people who want to listen to music and podcasts on a run without tuning out the rest of the world. Rather than anchoring to the skull, the sports headphones sit just in front of the ear, where your lower jaw meets your skull.

This is not entirely unlike how dolphins (and at least 65 species of toothed whales) detect sound.

Build your own BeagleBox 2!

A more comprehensive build guide, along with the 3D printer files, can be found in the BeagleBox GitHub Repository. 

 

The BeagleBox 2 is a dirt-cheat, tough, versatile field computer built from 3D-printed parts, off-the-shelf hardware, and a single board computer. You can read all about it here: The BeagleBox 2: a dirt-cheap, tough-as-nails, 3D-printed, versatile field laptop.

Let’s build one!

Build a dirt cheap, tough-as-nails field computer in a Pelican case

IMG_20150720_233502091For and updated version of the BeagleBox, please go here: The BeagleBox 2: a dirt-cheap, tough-as-nails, 3D-printed, versatile field laptop.

Fieldwork is tough. You’re in the elements, facing wind, rain, and salt spray, sometime on an open boat far out in the Atlantic. You and your gear takes a beating. But you’re out there because there’s science that need to get done.

But your equipment is controlled via computer, and your data entry mandates a computer, which means your precious laptop needs to come with you. For graduate students and early career scientists, this can be a dilemma. I’ve see the calculations happen as my colleagues prepare for the field–do I take my one and only computer out into the field and risk damaging it, or do I leave it brute-force my way through sampling without it. That is, if they’re lucky enough to have alternative methods they can employ. For some gear, there’s no choice but to take the computer.

This equation is, counter-intuitively, getting worse. Our sensors, sampling devices, and scanners are getting cheaper and lighter. Rather than buying a $20,000 piece of equipment, you can get a $20 chip, but there’s a trade off, and the trade off is that chip based systems rely on external processing power, they need a general computer, and that means your laptop is coming with you.

I don’t like going out on the water with my laptop. 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 build 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. Say hello to the BeagleBox, a dirt cheap, tough-as-nails field computer for about $200.
