For most of us, hacking is a hobby, something to pass a few idle hours and satisfy our need to create. Precious few of us get to live the dream of being paid to tinker; most of us need some kind of day job to pay the bills and support our hacking habits. This necessarily creates an essential conflict, rooted in the fact that we all only have 24 hours to spread around every day: I need to spend my time working so I can afford to hack, but the time I spend working to earn money eats away at my hacking time. That’s some catch, that Catch-22.
From that primary conflict emerges another one. Hacking is a hugely creative process, and while the artist or the author might not see it that way, it’s true nonetheless. Unless we’re straight-up copying someone else’s work, either because they’ve already solved the same problem we’re working on and we just need to get it done, or perhaps we’re just learning a new skill and want to stick to the script, chances are pretty good that we’re hitting the creative juices hard when we build something new. And that requires something perhaps even more limiting than time: inspiration. How you manage inspiration in large part dictates how productive you are in your creative pursuits.

Every once in a while, we stumble on an amazing resource that’s not exactly new, but it’s new to us. This is the case, in spades, with The Engines of Our Ingenuity, a radio show that’s been running since 1988!
Each episode covers an invention or engineering marvel, and tells the story of how it came to be, and puts each device into its historical and cultural context. Want to get the lowdown on how we safely bring fire into the kitchen? Or the largest land transport vehicle, NASA’s crawler? And what’s up with lobsters anyway?

In what is being hailed as the next great advancement in 3D printing, scientists have been able to get a 3D printed shape to change form when it is exposed to water, bringing 3D printing squarely into the realm of the fourth dimension. Although the only examples we’ve seen so far are with relatively flat prints (which arguably subtracts one “D” from the claim) the new procedure is one which is groundbreaking for the technology.
The process uses cellulose fibers which, when aligned in a particular way and exposed to water, swell in order to change shape. This is similar to how a bimetallic strip in a thermostat works, but they really took their inspiration from biological processes in plants that allow them to change shape according to environmental conditions. It’s hard to tell if this new method of printing will forever alter the landscape of 3D printing but, for now, it’s an interesting endeavor that will be worth watching. The video after the break shows a fast-motion print using the technique, followed by a demo of the print submersed in water.
We often see new technological advancements that use biology as a springboard for new ideas, and this one is no different. There have been building structures inspired by pinecones and this Processing hack inspired by squid. Biology is all around us, and any of it could be used for inspiration for your next project!
