DRONE BUOY DRIFTS ALONG THE GULF STREAM FOR CITIZEN SCIENCE

It may be named after the most famous volleyball in history, but “Wilson” isn’t just a great conversationalist. [Hayden Brophy] built the free-drifting satellite buoy to see if useful science can be done with off-the-shelf hardware and on a shoestring budget. And from the look of the data so far, Wilson is doing pretty well. Wilson belongs to a class of autonomous vessels known as drifters, designed to floa ...

Old Man and the Arduino GPS

So this Lazy Old Geek (L.O.G.) hasn’t been able to do an Instructable for a few years. At 70 years old, the brain doesn’t work as well as it used to and it’s hard to focus on big projects let alone try to write about them. (I am entering Arduino Contest.) But with the help of my loving dog, Sadie and my CPAP machine, I’m going to give it a try. Sadie is my anti-depressant, keeps my spirits up and we walk ev ...

Build the World’s Smallest Atomic Clock

For Fridtjof Nansen, 13 April 1895 started well. Six days earlier, the Norwegian explorer had set a new record for the closest approach to the North Pole, and now he was moving quickly over unbroken sea ice toward Cape Fligely and home. But then came a sickening realization: In his eagerness to break camp, he had forgotten to wind the chronometers. He had lost track of precise time, and thus the ability to ...
