Do-it-yourself science is taking off. A growing movement seeks to make the tools of science available to everyone (including you). I love that The Economist now has a “Punk Science” heading.
Palau now requires all tourists to sign an environmental pledge when they enter the country. All flights in now feature this delightful short film.

Arlo Guthrie was right! Cool short video of bipedal “walking” in gastropods. Clamzo boys, Clamzo!

Fog Horn (A Call to Action)

The CDC was given a list of seven banned words for their upcoming budgets. Among the censored words are “science-based” and “evidence-based”, which, of course, are concepts central to the CDC’s mission. I have some thoughts about why this list has appeared at this time. If you think the CDC shouldn’t be censored in their mission to safeguard public health, call your representatives.

Open source. Open science. Open Ocean. Oceanography for Everyone and the OpenCTD

Oceanography for Everyone

Nearly four years ago, Kersey Sturdivant and I launched a bold, ambitious, and, frankly, naive crowdfunding initiative to build the first low-cost, open-source CTD, a core scientific instrument that measures salinity, temperature, and depth in a water column. It was a dream born from the frustration of declining science funding, the expense of scientific equipment, … Read More “Open source. Open science. Open Ocean.

A 3D-printable, drone and ROV-mountable, water sampler

Education, Open Science, Science

The Niskin bottle, a seemingly simple tube designed to take water samples at discrete depths, is one of the most important tools of oceanography. Coupled with a CTD, an array of Niskin bottles fit into the rosette, a Voltron-esque amalgamation of everything an oceanographer needs to profile the ocean. Niskin bottles are neither cheap nor particularly easy to use. A commercial rosette requires a decent-sized winch to launch and recover, which means you need a vessel and a crew to deploy. For Rogue Ecologist and citizen scientists, getting a high-quality, discrete water sample is a perpetual challenge. With tools like the OpenROV and the soon-to-be-completed EcoDrone, I wanted a Niskin bottle that was light weight and capable of being mounted on both underwater robots and quadcopters with ease.

Until now.

After a few months of brainstorming and planning, I sat down this Friday and began building a 3D printable Niskin bottle that could be hand deployed or mounted on an OpenROV or drone. While this version is designed around a 1.25 inch acrylic tube, the trigger mechanism can be expanded to fit any size pipe. The trigger is driven by a waterproof servo developed by the good folks over at OpenROV. Everything else can either be purchased off-the-shelf or printed on you home 3D printer. Later this month, I’ll be taking my prototypes out on the RV Blue Heron for field testing in Lake Superior.

Hacking the Tractor: what the future of farming means for open science

July 20, 2015July 21, 2015 Andrew Thaler

Science

I took a gamble when I bought the tractor mower. It was old, but well-cared for and ran well, but it was wearing out. Still, I couldn’t get a quarter as much machine for twice the price. Two months later, the mower deck cracked, rusted out from ten years of hard use. A replacement deck would run into the thousands of dollars, there were no options for just the shell, a cheaper, but still pricey option, and there were no off-brand decks to be found. Those three facts alone should tell you that we’re dealing with a John Deere, here.

John Deere made headlines earlier this year when Wired ran an impressive (and rare) expose on farm tech: New High Tech Farm Equipment is a Nightmare for Farmer. Deere followed up with a rebuttal letter, declaring that farmers did, in fact, own their equipment, while simultaneously outlining all the ways in which they didn’t: John Deere: of course you “own” your tractor, but only if you agree to let us rip you off.

Here’s the short version: Tractors are complicated and increasingly controlled by onboard computers. These computers use proprietary software, and that software is protected by the Digital Millennium Copyright Act (DMCA). The software itself is encrypted to prevent copying or modding. Those encryption are also protected by the DMCA. Breaking that encryption is illegal, regardless of the state of the software. If you have to decrypt the software to remove it, you’re breaking the law.
