For most developers “distributed version control” probably means git. But by itself git doesn’t work very well with binary files such as images, zip files and the like because git doesn’t know how to make sense of the structure of an arbitrary blobs of bytes. So when trying to figure out how to track changes in design files created by most EDA tools git doesn’t get the nod and designers can be trapped in SVN hell. It turns out though KiCAD’s design files may not have obvious extensions like .txt, they are fundamentally text files (you might know that if you’ve ever tried to work around some of KiCAD’s limitations). And with a few tweaks from [jean-noël]’s guideyou’ll be diffing and merging your .pro’s and .sch’s with aplomb.
We’re neck deep in the Hackaday Prize, and we just wrapped up the Human Computer Interface Challenge. This is an incredible contest to go beyond traditional mice and keyboards to find new ways to transfer your desires directly into a computer.
You wake up in the morning, and check Hackaday over breakfast. Then it’s off to work or school, where you’ve already had to explain the Jolly Wrencher to your shoulder-surfing colleagues. And then to a hackspace or back to your home lab, stopping by the skull-and-cross-wrenches while commuting, naturally.
The greatest hardware competition on the planet is going on right now. The Hackaday Prize is the Oscars of Open Hardware. It’s the Nobel Prize of building a thing. It’s the Fields Medal of firmware development, and simply making it to the finals grants you a knighthood in the upper echelon of hardware developers.
From All the Badges of DEF CON 26 (vol 4) on Hackaday:
Hackaday Alum Sarah Petkus has been on a long quest to build an awesome robot with a lot of personality lovingly known as Noodle (check out her Hackaday Supercon talk on the adorable quadruped). For DC26 she decided to throw a con inside the con for Noodle and this is the badge.
Anyone following Sarah’s work knows that her art is on point and here is a great example. Look at the solder mask on front and rear and you’ll notice the lettering is mirrored. This gives it the appearance that this is a design you can see through the board. The bold use of patches of silk screen and gold-plated copper deliver her aesthetic boldly and make you just want to stare at the design. There is a little squiggle through the C on the front that is a superb touch! Driven by an ATmega328 and a CR2032, there are 10 LEDs on the back that flash for a backlight effect.
Who among us doesn’t procrastinate from time to time? We can’t count the number of times that we’ve taken advantage of the Post Office staying open until midnight on April 15th. And when the 15th falls on a weekend? Two glorious additional days to put off the inevitable!
If you’ve been sitting on submitting your talk or workshop proposal to the 2018 Hackaday Superconference, we’ve got the next best thing for you: we’re extending the deadline until 5 pm PDT on September 10th.
The Hackaday Superconference is a singularity of hardware hackers: more of the best people in the same space at the same time than anywhere else. And that means that your ideas and experiences will be shared with the people most likely to appreciate them. From heroic hacks to creative robotics or untold hardware histories, if there’s a crowd who’ll appreciate how a serial console saved your bacon, it’s this one.
And if you give a talk or workshop, you get in free. But it’s more than that — there’s a different experience of a convention, even a tight-knit and friendly one like Hackaday’s Supercon, when you’re on the other side of the curtain. Come join us! We’d love to hear what you’ve got to say. And now you’ve got a little more time to tell us.
(If you want to get in the old-fashioned way, tickets are still available, but they won’t be once we announce the slate of speakers. You’ve been warned.)
At Hackaday, we’re constantly impressed by the skill and technique that goes into soldering up some homebrew creations. We’re not just talking about hand-soldering 80-pin QFNs without a stencil, either: there are people building charlieplexed LED arrays out of bare copper wire, and using Kynar wire for mechanical stability. There are some very, very talented people out there, and they all work in the medium of wire, heat, and flux.
At this year’s DEF CON, we opened the floodgates to competitive soldering. Along with [Bunny] from Hardware Hacking Village and the many volunteers from the HHV and Soldering Skills Village, dozens competed to solder up a tiny kit full of LEDs and microscopic resistors.
The kit in question was an SMD Challenge Kit put together my MakersBox, and consisted of a small PCB, an SOIC-8 ATtiny, and a LED and resistor for 1206, 0805, 0603, 0402, and 0201 sizes. The contest is done in rounds. Six challengers compete at a time, and everyone is given 35 minutes to complete the kit.
