In 2013, Kersey Sturdivant and I embarked upon a quixotic quest to create an open-source CTD — the core tool of all oceanographic research that measures the baseline parameters of salinity, temperature, and depth. We weren’t engineers; neither of us had any formal training in electronics or sensing. And, full confession, we weren’t (and still aren’t) even oceanographers! What we were were post-doc marine ecologists working with tight budgets who saw a desperate need among our peers and colleagues for low-cost alternatives to insurmountably expensive equipment. And we had ties to the growing Maker and DIY electronics movements: Kersey through his work developing Wormcam and me through my involvement with OpenROV.
We had no idea what we were getting ourselves into.
Seven years and five iterations later, we are releasing the long anticipated OpenCTD rev 2 as well as the comprehensive Construction and Operation Manual! OpenCTD rev 2 builds on over half a decade of iteration and testing, consultation with oceanographers, engineers, developers, and makers around the world, extensive coastal and sea trials, and a series of workshops designed to test and validate the assembly process.
Confession: I have an Amazon Echo. I really like Amazon Echo. I use Amazon Echo almost every day.
Everything about the Amazon Echo is great, except for the primary feature of the Amazon Echo: it is always listening. When I received the Echo nearly five years ago, as a gift, Amazon was not quite the Surveillance Capitalism behemoth that it is now. They packaged their new smart speaker with lots of information about privacy and what Echo can and can’t and won’t do.
It’s reached the point where no one should feel comfortable
having an always-on speaker in their home, but damn if these little things aren’t
just so convenient. On top of being useful for quick searches, playing Baby Shark
on repeat 40 times, checking the weather, and dozens of other little things,
the original Echo was a really good speaker. It seems a waste to throw the
whole thing away just because one feature is unacceptable.
The future of fitness tracking is here! reStepper is an open-source, arduino-powered machine to walk your fitness tracker after those unfortunate workouts when your steps didn’t get logged. Did you have the audacity to take you child for a walk in a stroller? Get those steps back! Were you foolish enough to go swimming when you could have walked in aimless circles around the pool? Don’t let the credit drift away! Reckless enough to do something, anything, that might require you to take off your jewelry before working up a sweat? Let the reStepper sweat it all back! Maybe you just don’t want third parties to know where you run, or where your secret morel patch is, or how fast they need to make the people harvesting machines in order to catch Charlton Heston.
So what is it?
The reStepper is an open-source machine that “walks” a fitness tracker for you.
