Location, location, location — what’s critical to real estate is also critical to eclipse watching, and without sounding too boastful, those of us atop South Menan Butte, an extinct volcano in southeast Idaho, absolutely nailed it. Not only did we have perfect weather, we had an excellent camping experience, great food, a magnificent natural setting, and a perch 800 feet above a vast plain stretching endlessly to the east and west. Everything was set up for a perfect eclipse experience, and we were not disappointed.
While most people who make the trek to the path of totality for the Great American Eclipse next week will fix their gazes skyward as the heavenly spectacle unfolds, we suspect many will attempt to post a duck-face selfie with the eclipsed sun in the background. But at least one man will be feverishly tending to an experiment.
On a lonely hilltop in Wyoming, Dr. Don Bruns will be attempting to replicate a famous experiment. If he succeeds, not only will he have pulled off something that’s only been done twice before, he’ll provide yet more evidence that Einstein was right.
What would you do if you found hidden away artifacts of aerospace technology from the Apollo era?
You call NASA.
Two hulking computers — likely necessitating the use of a crane to move them — and hundreds of tape reels were discovered in the basement of a former IBM engineer by their heir and a scrap dealer cleaning out the deceased’s home. Labels are scarce, and those that are marked are mostly from the late 1960s through the mid 1970s, including data from the Pioneer 8 to 11 missions, as well as the Helios missions.
The Hackaday Prize is more than just giving tens of thousands of dollars to hardware hackers. It’s also about funding the next batch of Open Source hardware products. Alongside The Hackaday Prize — the contest where we’re funding hardware that will change the world, — we’re also giving away $30,000 to the project that will best become a product. It’s almost like we’re funding hardware startups here.
[Dessislav Gouzgounov] wanted to build a small piece of hardware — a GoTo for his telescope. This handheld controller would allow him to use software to align the telescope with whatever celestial body he’s checking out.
Many GoTos simply interface with a laptop, but [Dessislav] built a standalone system centered around an Arduino Due and 240×400 touch screen, with GPS, RTC, and Bluetooth under the hood. It works on both hemispheres and contains a database of 250 celestial objects, features different speeds for time-delayed tracking of celestial, lunar, and solar phenomena, and it can work with any stepper-equipped telescope.
We covered [Dessislav]’s previous version of the RDuinoScope, but he’s improved the project considerably with over 2,400 lines of code including a new menu system and added a star atlas showing the location of the sky at which the telescope is currently pointed, among other improvements. The project is open source and you can learn more about it on [Dessislav]’s project page or check out his code on GitHub.
I found myself staring up at the sky on the night of March 13, 1989, with my girlfriend and her parents in the backyard of their house. The sky was on fire, almost literally. Red and pink sheets of plasma streamed out in a circle from directly overhead, with blue-white streaks like xenon flashes occasionally strobing across the sky. We could actually hear a sizzling, crackling sound around us. The four of us stood there, awestruck by the aurora borealis we were lucky enough to witness.
At the same time, lights were winking out a couple of hundred miles north in Québec province. The same solar storm that was mesmerizing me was causing fits for Hydro-Québec, the provincial power authority, tripping circuit breakers and wreaking havoc. This certainly wasn’t the first time the Sun threw a fit and broke systems on Earth, but it was pretty dramatic, and there are some lessons to be learned from it and other solar outbursts.
[Barry Armstead] is an astronomy enthusiast who built his own observatory in his front yard, in Canberra, Australia. It was a fine observatory as home-made observatories go, but he describes it as being small and cramped. His replacement was on an entirely different scale though, a building created by hand and which no doubt many readers would be pleased to own.
His design started with a cardboard model, and has a downstairs room upon which sits a rotatable dome with two sliding sections to form the observation window. The original observatory’s concrete pillar on which the telescope mount stood remained post-demolition, and a larger concrete pad was laid. There followed the assembly of a steel frame with a skeletal dome able to rotate on rollers, followed by cladding with steel sheet. The dome cladding was done in segments marked against the dome steelwork and cut to shape.
The final building has a fully finished interior downstairs, plus a rustic staircase to the upper deck. The concrete post has been extended, and now carry’s [Barry]’s telescope which he controls not with his eye clued to an eyepiece like the astronomers of old, but from a computer at the adjacent desk. The full construction details are on the observatory’s web site, though since it seems in danger of disappearing due to an expired hosting account we’ll also give you a Wayback Machine link direct to the relevant page. Meanwhile he offers a tour in a video we’ve placed below the break. Even a non-astronomer would find this an asset in their garden!
On August 21, 2017, the moon will cast its shadow across most of North America, with a narrow path of totality tracing from Oregon to South Carolina. Tens of millions of people will have a chance to see something that the continental US hasn’t seen in ages — a total eclipse of the sun. Will you be ready?
The last time a total solar eclipse visited a significantly populated section of the US was in March of 1970. I remember it well as a four-year-old standing on the sidewalk in front of my house, all worked up about space already in those heady days of the Apollo program, gazing through smoked glass as the moon blotted out the sun for a few minutes. Just watching it was exhilarating, and being able to see it again and capitalize on a lifetime of geekiness to heighten the experience, and to be able to share it with my wife and kids, is exciting beyond words. But I’ve only got eight months to lay my plans! Continue reading “Get Ready for the Great Eclipse of 2017”
