Friday Hack Chat: Eagle One Year Later

December 14, 2017 by Brian Benchoff 103 Comments

Way back in June of 2016, Autodesk acquired Cadsoft, and with it EagleCAD, the popular PCB design software. There were plans for some features that should have been in Eagle two decades ago, and right now Autodesk is rolling out an impressive list of features that include UX improvements, integration with MCAD and Fusion360, and push and shove routing.

Six months into the new age of Eagle, Autodesk announced they would be changing their licensing models to a subscription service. Where you could pay less than $100 once and hold onto version 6.0 forever, now you’re required to pay $15 every month for your copy of Eagle. Yes, there’s still a free, educational version, but this change to a subscription model caused much consternation in the community when announced.

For this week’s Hack Chat, we’re going to be talking about Eagle, one year in. Our guest for this Hack Chat is Matt Berggren, director of Autodesk Circuits, hardware engineer, and technologist that has been working on bringing electronic design to everyone. We’ll be asking Matt all about Eagle, with questions including:

What new features are in the latest edition of Eagle?
What’s on the Eagle wishlist?
What technical challenges arise when designing new features?
Where can a beginner find resources for designing PCBs in Eagle?

Join the chat to hear about new features in Eagle, how things are holding up for Eagle under new ownership, and how exactly the new subscription model for Eagle is going. We’re looking for questions from the community, so if you have a question for Matt or the rest of the Eagle team, put it on the Hack Chat event page.

If you’re wondering about how Altium and KiCad are holding up, or have any questions about these PCB design tools, don’t worry: we’re going to have Hack Chats with these engineers in the new year.

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This Hack Chat is going down on noon, PST, Friday, December 15th. Time Zones got you down? Here’s a handy count down timer!

You don’t have to wait until Friday; join whenever you want and you can see what the community is talking about.

Extraterrestrial Autonomous Lander Systems To Touch Down On Mars

December 13, 2017 by Brian Benchoff 24 Comments

The future of humans is on Mars. Between SpaceX, Boeing, NASA, and every other national space program, we’re going to Mars. With this comes a problem: flying to Mars is relatively easy, but landing a large payload on the surface of another planet is orders of magnitude more difficult. Mars, in particular, is tricky: it has just enough atmosphere that you need to design around it, but not enough where we can use only parachutes to bring several tons down to the surface. On top of this, we’ll need to land our habitats and Tesla Roadsters inside a very small landing ellipse. Landing on Mars is hard and the brightest minds are working on it.

At this year’s Hackaday Superconference, we learned how hard landing on Mars is from Ara Kourchians (you may know him as [Arko]) and Steve Collins, engineers at the Jet Propulsion Laboratory in beautiful Pasadena. For the last few years, they’ve been working on COBALT, a technology demonstrator on how to use machine vision, fancy IMUs, and a host of sensors to land autonomously on alien worlds. You can check out the video of their Supercon talk below.

Hackaday Links: December 10, 2017

December 10, 2017 by Brian Benchoff 14 Comments

We have a contest going on right now challenging you to do the most with a coin cell. There are already quite a few interesting entries, and a few Hackaday writers are getting into the action by asking the question, ‘how do you open up a coin cell?’. The first thoughts were to open a lithium coin cell up while submerged in oil, but eBay came to the rescue with the cases for CR2025 cells. Of course that’s a thing.

Also falling into the, ‘of course that’s a thing’ category, there’s a project on Hackaday.io to execute arbitrary code on a calculator. A small group of calculator hackers have discovered an exploit on a line of Casio calculators running the obscure nX-U8/100 architecture. Right now, there’s not much to the project — just an LCD filled with bits of memory. However, this is a project we’re keenly watching, and we can’t wait to see what comes of it.

Hold onto your butts, because the ultimate multimeter is here. [Dave Jones] of the EEVBlog has released the 121GW Multimeter on Kickstarter. What’s cool about this meter? SD card logging, the ability to send data over Bluetooth, a 15V diode test voltage, a burden voltage display, and a whole bunch of hackable features. If you have a Fluke on your Christmas list, you would do well to check out the 121GW.

Also on Kickstarter, a new LattePanda board has been released. What’s a LattePanda? It’s a small single board computer built around a low-voltage Intel processor. This board features an Intel m3-7Y30 processor, comparable to the processor you’d get in a proper laptop that doesn’t have an i3, 8 gigs of DDR3, 64 gigs of eMMC, 802.11ac, BlueTooth 4.2, USB 3.0 with a Type C connector, HDMI, and a whole bunch of GPIOs. Yes, it runs Windows (but why would you?). If you need a somewhat beefy x86 system in a small form factor, there ‘ya go.

We’ve seen 3D printed remote-controlled airplanes, but never one this big. The guys at Flite Test printed a 1.6 meter Spitfire. It’s got flaps, it’s got retracts, and it’s friggin’ huge. The files for the print came from 3DLabPrint, and it flies beautifully, despite being a Spitfire. Want to see the video? Here ya go.

Ask Hackaday: Prove Santa Exists

December 9, 2017 by Jenny List 63 Comments

There is no question, that Santa Claus exists. He’s real, with the sleigh, the beard, and the reindeer and everything. He distributes gifts to billions of children in an evening, squeezes down a billion chimneys without getting that stylish red outfit dirty, and gets back home to the North Pole before sunrise. What more proof do you need, after all the missile defence folks track his progress over the icy wastes every Christmas Eve!

Well, the previous paragraph is the story you’ll get from the average youngster in countries where St. Nick is a cultural fixture, and who are we to disabuse them of this notion. Certainly not [Dave Barrett], who has the task of coming up with some ideas for a Santa Proof Of Existence for a kids’ Christmas party. In a previous year he’s thrilled them with a view of the sleigh taking off (in reality a remote-controlled model rocket launch complete with fake air traffic control clearance for Santa via CB radio), but this year the party isn’t somewhere with the space to do that trick. Instead he has the task of maintaining the illusion in those young minds for another year, with only a modest suburban plot in which to do it.

How would you prove Santa’s existence for the credulous young party-goers, using the finest technological marvels available to the Hackaday community? Perhaps you might create the illusion of boots crunching in the snow outside, or maybe the not-so-distant sound of reindeer. We suggest a Santa-Pede won’t cut it, and neither will hiring the beardy member of your hackspace as a stand-in. Kids aren’t that stupid!

What do you think? Go nuts in the comments.

Danielle Applestone: Building The Workforce Of 2030

December 8, 2017 by Dan Maloney 46 Comments

You wake up one morning with The Idea — the one new thing that the world can’t do without. You slave away at it night and day, locked in a garage expending the perspiration that Edison said was 99 percent of your job. You Kickstart, you succeed, you get your prototypes out the door. Orders for the new thing pour in, you get a permanent space in some old factory, and build assembly workstations. You order mountains of parts and arrange them on shiny chrome racks, and you’re ready to go — except for one thing. There’s nobody sitting at those nice new workstations, ready to assemble your product. What’s worse, all your attempts to find qualified people have led nowhere, and you can’t even find someone who knows which end of a soldering iron to hold.

Granted, the soldering iron lesson is usually something that only needs to happen once, but it’s not something the budding entrepreneur needs to waste time on. Finding qualified workers to power a manufacturing operation in the 21st century is no mean feat, as Dr. Danielle Applestone discussed at the 2017 Hackaday Superconference. Dr. Applestone knows whereof she speaks — she was the driving force behind the popular Othermill, serving as CEO for Other Machine Co. and orchestrating its rise to the forefront of the desktop milling field. Now rebranded as Bantam Tools, the company is somewhat unique in that it doesn’t ship its manufacturing off to foreign shores — they assemble their products right in the heart of Berkeley, California. So finding qualified workers is something that’s very much on her mind on a daily basis.

Sarah Petkus On Building A Cartoon To Go To Mars

December 6, 2017 by Brian Benchoff 24 Comments

Sarah Petkus is a robot mom (which means she’s the mother to a robot, not that Sarah herself is a robot, at least as far as we’re aware), whose child, Noodle Feet, is a character in Sarah’s graphic novel Gravity Road. Unlike every other robot on the planet, Noodle Feet is a content-based robot. Instead of robotic arms welding car panels together or 3D printers squiring out goo, Noodle Feet isn’t a robot built for a specific function. Noodle Feet’s design is derived from his personality in his graphic novel. In the graphic novel, Noodle Feet tastes with his feet, clambers over rocks, and explores his surroundings. That’s what the real-life version of Noodle Feet must do, and that means building the hardware to do just that.

Sarah has been working on Noodle Feet for about two years now, and last year she presented a talk about tasting feet and salivating toes. It’s odd, yes, but it is a fantastic exploration of what can be done with robotics.

This year, Sarah had the opportunity to be an artist in residence at ESA, where Noodle Feet could at least test out his dream of living on Mars. There, Noodle Feet played around in the ESA’s Mars yard, where he made friends with a copy of the ExoMars rover.

Friday Hack Chat: Contributing To Open Source Development

December 6, 2017 by Brian Benchoff 13 Comments

Open Source is how the world runs. Somewhere, deep inside the box of thinking sand you’re sitting at right now, there’s code you can look at, modify, compile, and run for yourself. At every point along the path between your router and the horrific WordPress server that’s sending you this webpage, there are open source bits transmitting bytes. The world as we know it wouldn’t exist without Open Source software.

That said, how does someone contribute to Open Source? Maintainers do like to build their own little kingdoms, so how does anyone break into developing Open Source hardware and software?

Our guest for this Hack Chat will be Robert Wolff, technical writer, and Open Source evangelist who has a history of working in and around STE*M-based educational programs. Right now, Robert is the community manager for 96Boards at Linaro. 96Boards is a hardware specification to make the latest ARM-based processors available at a reasonable cost. This open specification defines a standard board layout for SoC-agnostic platforms that can be used by any application, device, and kernel by system software developers.

The questions we’ll be looking at during this Hack chat is how to contribute to Open Source projects, how to do that using 96Boards, the technical challenges involved in documenting an Open system, the difficulty in designing a processor-agnostic system, and general questions about the 96Boards community, ecosystem, and resources.

As always, we’re going to be taking questions from the hackaday.io community, so if you have a question, drop it on the Hack Chat event page.

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. These Hack Chats usually happen at Noon, Pacific time, on Friday. This week, everything is going down on Noon, PST, Friday, December 8th. Don’t have any idea what time that is on your meridian? Here’s a handy countdown timer!
