Katrina Nguyen Automates Her Mice

November 29, 2018 by Dan Maloney 5 Comments

When embarking on a career in the life sciences, it seems like the choice of which model organism to study has more than a little to do with how it fits into the researcher’s life. I once had a professor who studied lobsters, ostensibly because they are a great model for many questions in cell biology; in actuality, he just really liked to eat lobster. Another colleague I worked with studied salt transport in shark rectal glands, not because he particularly liked harvesting said glands — makes the sharks a tad grumpy — but because he really liked spending each summer on the beach.

Not everyone gets to pick a fun or delicious model organism, though, and most biologists have had to deal with the rats and mice at some point. It’s hard to believe how needy these creatures can be in terms of care and feeding, and doubly so when feeding is part of the data you’re trying to collect from them. Graduate student Katrina Nguyen learned this the hard way, but rather than let her life be controlled by a bunch of rodents, she hacked a solution that not only improved her life, but also improved her science. She kindly dropped by the Hackaday Superconference to tell us all about how she automated her research.

Bill Gross On Why Your Startup Will Succeed

November 27, 2018 by Brian Benchoff 16 Comments

Bill Gross is one of the great heros when it comes to technology incubators. Twenty years ago, he founded Idealab, a business whose business plan is to create more businesses. This started out with just a handful of companies in 1996, and has since gone on to found 150 companies, that have collectively raised three and a half billion dollars. Out of these companies, more than half have either gone through successful IPOs and acquisitions, or are currently operating. That investment has generated a 13.5x return, and created more than 10,000 jobs.

Obviously, when you want to talk about what goes into a successful startup, Bill Gross is the person you want to talk to. We were happy to have him Keynote the Hackaday Superconference this year, and the lessons he shared might surprise you, especially if you’re interested in starting your own business.

Hackaday Assembling At 35C3

November 26, 2018 by Elliot Williams 5 Comments

Hackaday is going to be at the 35th annual Chaos Communication Congress (35C3), December 27th – 31st, and we’re putting together an assembly. If you’re coming to 35C3, come join us!

If you’ve never been to a Congress before, it’s an amazing scene. This year over 15,000 hackers will take over the Leipzig Congress Hall, bringing whatever they’re working on with them, and showing off their last-minute dazzlers. Congress is awesome in both senses of the word: simultaneously incredible and a little bit intimidating.

With the scale of the Congress approaching absurd proportions, it’s nice to have a home base. “Assemblies”, small-ish gatherings of friends, members of a hackerspace, or even just like-minded folks, join forces and get some table space and Ethernet connections to call their own, and this year we’ll be flying the Jolly Wrencher.

November 28th is the deadline for changing our headcount, so if you’d like to take part, click over to the Hackaday 35C3 Assembly IO project ASAP and leave a comment or join the team so we have a good estimate. If you’ve already got a home away from home, we’ll keep some extra seats warm for you to come by and chat. [Elliot] will also be wearing his press hat, so if you’ve got a project in desperate need of a Hackaday writeup you’ll know where to find him.

Hackaday, assemble!

Of Roach Killer And Rust Remover: Sam Zeloof’s Garage-Made Chips

November 19, 2018 by Dan Maloney 28 Comments

A normal life in hacking, if there is such a thing, seems to follow a predictable trajectory, at least in terms of the physical space it occupies. We generally start small, working on a few simple projects on the kitchen table, or if we start young enough, perhaps on a desk in our childhood bedroom. Time passes, our skills increase, and with them the need for space. Soon we’re claiming an unused room or a corner of the basement. Skills build on skills, gear accumulates, and before you know it, the garage is no longer a place for cars but a place for pushing back the darkness of our own ignorance and expanding our horizons into parts unknown.

It appears that Sam Zeloof’s annexation of the family garage occurred fairly early in life, and to a level that’s hard to comprehend. Sam seems to have caught the hacking bug early, and by the time high school rolled around, he was building out a remarkably well-equipped semiconductor fabrication lab at home. Sam has been posting his progress regularly on his own blog and on Twitter, and he dropped by the 2018 Superconference to give everyone a lesson on semiconductor physics and how he became the first hobbyist to produce an integrated circuit using lithographic processes.

Supercon: Designing Your Own Diffractive Optics

November 16, 2018 by Brian Benchoff 15 Comments

Kelly Peng is an electrical and optical engineer, and founder of Kura AR. She’s built a fusion reactor, a Raman spectrometer, a DIY structured light camera, a linear particle accelerator, and emotional classifiers for likes and dislikes. In short, we have someone who can do anything, and she came in to talk about one of the dark arts (pun obviously intended): optics.

The entire idea of Kura AR is to build an immersive augmented reality experience, and when it comes to AR glasses, there are two ways of doing it. You could go the Google Glass route and use a small OLED and lenses, but these displays aren’t very bright. Alternatively, you could use a diffractive waveguide, like the Hololens. This is a lot more difficult to manufacture, but the payoff will be a much larger field of view and a much more immersive experience.

An In-Depth Look At Dexter, The Robotic Arm

November 15, 2018 by Elliot Williams 25 Comments

Dexter, a really great robot arm project, just won top honors in the 2018 Hackaday Prize, and walked away with $50,000 toward continuing their project. As a hat tip to Hackaday and the community, Haddington Dynamics, the company behind Dexter, agreed to open-source their newest version of Dexter as well. As James Newton said when accepting the trophy during the award ceremony, “because of your faith in us, because of this award, we have been moved to open-source the next generation of Dexter.” Some very clever work went into producing Dexter, and we can’t wait to see what further refinements have been made!

Dexter isn’t the only robotic arm in town, by any means. But in terms of hobbyist-level robotics, it’s by far the most complete robot arm that we’ve seen, and it includes a couple of design features that make both its positional accuracy and overall usability stand out above the rest. This is a robot arm with many of the bells and whistles of a hundred-thousand dollar robot, but on a couple-thousand dollar budget. Continue reading “An In-Depth Look At Dexter, The Robotic Arm” →

Hackaday Meetup At Electronica: Thursday

November 13, 2018 by Elliot Williams 10 Comments

Hackaday’s parent company Supplyframe is at Electronica in Munich this week — booth C5-223. On Thursday from 16:00 – 18:00, they’ll be hosting a Hackaday Happy Hour, with a beer and coffee bar, for everyone in the Hackaday community. They’d love to see you and hear what you’re working on, be it for your day job or your night job.

If you missed the #badgelife exhibit at Supercon, it’s here at Electronica. There will also be some of those mysterious cubes you may have heard about. Richard Hogben and Bogdan Rosu will be DJing fresh beats. Stop by and say hi to [Sophi Kravitz], [Majenta Strongheart], [Alek Bradic], and everyone else from the Supplyframe team.

Hackaday’s own [Elliot Williams] will also be wandering around Electronica Wednesday afternoon. He can’t promise free beer, but if you want to crawl around Electronica with [Elliot], meet up at the Supplyframe booth at 14:30 on Wednesday.
