Collaborate Disseminate
With Earth in the throes of climate change and no suitable Planet B lined up just yet, oceanography is as important now as it has ever been. And yet, the instruments relied upon for decades to test ocean conditions are holding steady within the range of expensive to prohibitively expensive. …read more
For all the successes of modern weather forecasting, where hurricanes, blizzards, and even notoriously unpredictable tornadoes are routinely detected before they strike, reliably predicting one aspect of nature’s fury has eluded us: earthquakes. The development of plate tectonic theory in the middle of the 20th century and the construction of …read more
Soap cleans clothes better than magnets. There, we are spoiling the ending so don’t accuse us of clickbaiting. The funny thing is that folks believe this is plausible enough to ask magnets experts so often that they dedicate a blog entry to comparing magnets and soap. Since you already know …read more
Can you electronically enhance your brain? I’m not talking about surgically turning into a Borg. But are there electronic methods that can improve various functions of your brain? Fans of brainwave entrainment say yes.
There was an old recruiting ad for electrical engineers that started with the headline: The best …read more
Join us on Wednesday at noon Pacific time for the high-altitude ballooning Hack Chat!
The Cope brothers are our hosts this week. Jeremy, a computer engineer, and Jason, a mechanical engineer, have recently caught the high-altitude ballooning (HAB) bug. In their initial flights they’ve racked up some successes and pushed the edge of space with interesting and varied missions. Their first flight just barely missed the 100,000 foot (30,000 meter) mark and carried a simple payload package of cameras and GPS instruments and allowed them to reach their goal of photographing the Earth’s curvature.
Flight 2 had a similar payload …read more
A unique project turned students at schools around the world into citizen scientists. Continue reading Kid Scientists Capture Rare Footage of Endangered Animals on Camera Traps
Scientific equipment is expensive. It can cost hundreds of thousands of dollars to set up a lab. Simply the cost of machines, like data acquisition units or even a simple load cell, can cost hundreds of dollars. This makes research cost prohibitive, and that’s the case even if you do spend a dozen hours a week writing grant proposals. Citizen science is right out, because the cost of the tools to do science is so high.
For this week’s Hack Chat, we’re going to be talking about Open Hardware for science. This is the chat that’s all about Open Source …read more

[Douglas] hometown Goshen, Indiana takes the state’s motto ‘The Crossroads of America’ seriously, at least when it comes to trains. The city is the meeting point of three heavily frequented railroad tracks that cross near the center of town, resulting in a car-traffic nightmare. When everybody agrees that a situation is bad, it is time to quantify exactly how bad it is. [Douglas] stepped up for this task and delivered.
He describes himself as cheap, and the gear he used to analyze the railroad traffic at a crossing visible from his home certainly fits the bill: a decades-old webcam, a …read more
[Dan Julio] let us know about an exciting project that he and his team are working on at the Solid State Depot Makerspace in Boulder: the Solar Eclipse High Altitude Balloon. Weighing in at 1 kg and bristling with a variety of cameras, the balloon aims to catch whatever images are able to be had during the solar eclipse. The balloon’s position should be trackable on the web during its flight, and some downloaded images should be available as well. Links for all of that are available from the project’s page.
High altitude balloons are getting more common as a …read more

There’s a big to-do going on right now in Germany over particulate-matter air pollution. Stuttgart, Germany’s “motor city” and one of Dante’s seven circles of Hell during rush hour, had the nation’s first-ever air pollution alert last year. Cities are considering banning older diesel cars outright. So far, Stuttgart’s no-driving days have been voluntary, and the change of the seasons has helped a lot as well. But that doesn’t mean there’s not a problem.
But how big is the issue? And where is it localized? Or is particulate pollution localized at all? These questions would benefit from a distributed network …read more
