The Hacker Village Of Supercon

I’m utterly exhausted and still in a state of awe. The Hackaday Superconference has grown in so many ways, but one thing remains the same: the spirit of the Hacker Village — an intangible feeling that grows up around all who attend — is bliss to take part in.

There’s really no substitute for having been there in person. I’ll go into detail below and try to share the experience as best I can. But the gist of the atmosphere is this: everyone at Supercon is the type of person you’d want to be stuck in a rowboat with, or partnered with on an engineering project, or to have next to you while trying to save the world. There are no looky-loos at Supercon. It turns out we are all stuck in a rowboat together, we are all working on engineering projects, and we are all trying to save the world. And when we all get together it feels like a drug our pragmatic minds never knew existed. This is the recharge for that sense of urgency that keeps you going all year long.

So yes, you really missed it. But start now. Become friends with all of these people over the next year. Begin building your Supercon community now and it’ll feel like a reunion when it rolls around again next November.

Peggy Whitson, Space Scientist

When astronaut Dr. Peggy Whitson returned from space earlier this year, it was a triumphant conclusion to a lifelong career as a scientist, explorer, and leader. Whitson is a biochemist who became one of the most experienced and distinguished astronauts ever to serve. She’s got more time logged in space than any other American. There’s a reason that she’s been called the Space Ninja.

Education and Early Life

Some people find their vocation late in life, but Peggy Whitson figured it out in her senior year of high school. It was 1979 and NASA had just accepted its first class of female astronauts, including Christa McAuliffe and Judith Resnik who ultimately died aboard the Challenger.

Born on a family farm in Iowa in 1960, Whitson began working on her plan, with the stereotypical Midwestern work ethic seeming to prime her for the hard slog ahead. She earned a BS in Biology/Chemistry, Summa, from Iowa Wesleyan, before earning a Ph.D. in biochemistry from Rice in 1985. A person can write about Whitson blazing through to a doctorate in a single sentence, but the truth is that it’s just a lot of hard work, and that’s one of the aspects of her career that stands out: she worked tirelessly.

Scientist Career

After getting her doctorate, Whitson worked as a research associate at Johnson Space Center as part of a post-doctoral fellowship. She put in a couple of years as a research biochemist, working on biochemical payloads
like the Bone Cell Research Experiment in STS-47, which was run in space by fellow badass Dr. Mae Jamison. Whitson hadn’t given up on her dream of becoming an astronaut herself, and the whole time she worked at Johnson she was applying to NASA. It took ten years and five applications before she made it in.

In the meantime, however, Whitson was given a lot of very cool projects and also began to establish her credentials as a leader, serving as Project Scientist of the Shuttle-Mir Program from 1992 till 1995. For three years she helped lead Medical Sciences Division at Johnson. The two years after that she co-chaired the NASA committee on US-Russian relations. And because she still had more time to crush it, she also worked as an adjunct professor at the University of Texas Medical Branch as well as at Rice.

Then, in April of 1996, she learned that her hard work had paid off and that she had been accepted into astronaut school. Peggy Whitson was going to space.

Ad Astra

It would be eight more years before she made it to space, however. Two years of intense training was followed by ground-based technical duties, including two years spent in Russia in support of NASA crews there. However, in 2002 she got her chance, flying in a Soyuz up to the International Space Station as part of Expedition 5. There she conducted science experiments and helped install new components in the space station, logging 164 days in space.

Back on earth, Whitson continued to kick ass as a scientist, astronaut, and leader. In 2003 she commanded a 10-day underwater mission that helps trains astronauts for extended stays in space, preparing her for her signature accomplishments: two tours where she commanded the ISS.

In 2008 she led Expedition 16, in which three additional modules were added to the ISS. Because of the new construction, and despite her science focus, Whitson became one of NASA’s most prolific spacewalkers, making 10 EVAs in her career — second only to cosmonaut Anatoly Solovyev’s 16 and her cumulative EVA time of 60 hours is third best in the world.

The three years that followed she served as Chief Astronaut, before she returned to space in November 2016 as commander of Expedition 50. Compared to 16 it was much more mellow, albeit with hundreds of biochemistry experiments conducted. In April of 2017, Whitson surpassed the U.S. space endurance record, earning her a call from the President. She ended up with 665 days in space, returning September 2 as a hero.

Dr. Peggy Whitson’s brilliance and tireless drive have earned her innumerable awards and commendations. Her elementary school has a science lab named after her. This year Glamour named her one of their women of the year. She serves as an inspiration to anyone who aspires to a career in science, math, or space exploration: it won’t be easy, and it will take a really long time, but it’s the kind of work that makes the world a distinctly better place.

Telepresence Robot 2000 Leagues Under The Sea

Telepresence robots are now a reality, you can wheel around the office and talk to people, join a meeting, see stuff and bump into your colleagues. But imagine if telepresence were applied to deep sea exploration. Today we can become oceanographers through the telepresence system created by Bob Ballard (known for locating the Titanic, discovered deep sea geothermal vents, and more) and his team at the Inner Space Center. Put on your Submariner wristwatch because its time for all of us to explore the ocean depths via the comfort of our home or office.

Hacked Sea Scooter Lives Another Day

The Seadoo GTI Sea Scooter is a simple conveyance, consisting of a DC motor and a big prop in a waterproof casing. By grabbing on and firing the motor, it can be used to propel oneself underwater. However, [ReSearchITEng] had problems with their unit, and did what hackers do best – cracked it open to solve the problem.

Investigation seemed to suggest there were issues with the logic of the motor controller. The original circuit had a single FET, potentially controlled through PWM.  The user interfaced with the controller through a reed switch, which operates magnetically. Using reed switches is very common in these applications as it is a cheap, effective way to make a waterproof switch.

It was decided to simplify things – the original FET was replaced with a higher-rated replacement, and it was switched hard on and off directly by the original reed switch. The logic circuitry was bypassed by cutting traces on the original board. [ReSearchITEng] also goes to the trouble of highlighting potential pitfalls of the repair – if the proper care isn’t taken during the reassembly, the water seals may leak and damage the electronics inside.

Overall it’s a solid repair that could be tackled by any experienced wielder of a soldering iron, and it keeps good hardware out of the landfill. For another take on a modified DC motor controller, check out the scooter project of yours truly.

 

Invention Killed The Inventor

The desire to innovate and change the world can drive one to take dangerous risks. Sometimes, inventors pay the ultimate price. Inventors can be early testers of a device under development, and sometimes pushing the limits of what’s possible has deadly consequences. In this era of warning labels on coffee cups, it’s perhaps worth taking a look back at some inventors of the past who lost their lives in the pursuit of building something new.

Intel’s Vision For Single Board Computers Is To Have Better Vision

At the Bay Area Maker Faire last weekend, Intel was showing off a couple of sexy newcomers in the Single Board Computer (SBC) market. It’s easy to get trapped into thinking that SBCs are all about simple boards with a double-digit price tag like the Raspberry Pi. How can you compete with a $35 computer that has a huge market share and a gigantic community? You compete by appealing to a crowd not satisfied with these entry-level SBCs, and for that Intel appears to be targeting a much higher-end audience that needs computer vision along with the speed and horsepower to do something meaningful with it.

I caught up with Intel’s “Maker Czar”, Jay Melican, at Maker Faire Bay Area last weekend. A year ago, it was a Nintendo Power Glove controlled quadcopter that caught my eye. This year I only had eyes for the two new computing modules on offer, the Joule and the Euclid. They both focus on connecting powerful processors to high-resolution cameras and using a full-blown Linux operating system for the image processing. But it feels like the Joule is meant more for your average hardware hacker, and the Euclid for software engineers who are pointing their skills at robots but don’t want to get bogged down in first-principles of hardware. Before you rage about this in the comments, let me explain.
