Electronic conference badges have been around for at least a decade now, and they all have the same faults. They’re really only meant to be used for a few days, conference organizers and attendees expect the badge to be cheap, and because of the nature of a conference badge, the code just works, and documentation is sparse. Surely there’s a better way.
Enter the Hackable Electronic Badge. Ever since Parallax started building electronic conference badges for DEF CON, they’ve gotten a lot of requests to build badges for other conventions. Producing tens of thousands of badges makes Parallax the go-to people for your conference badge needs, but the requests for badges are always constrained by schedules that are too short, price expectations that are too low, and volumes that are unknown.
There’s a market out there for electronic conference badges, and this is Parallax’s solution to a recurring problem. They’re building a badge for all conferences, and a platform that can be (relatively) easily modified while still retaining all its core functionality.

Dutch security conference! It’s called hardwear.io, it’ll be in The Hague during the last week of September, and they have the CTO of Silent Circle/Blackphone giving the keynote.
Baltimore’s awesome despite what the majority of the population says, and they have a few hackerspaces. One of them has an Indiegogo going right now to save the space. Want a tour of the space? Here you go.
[Fran Blanche] made it on to the Amp Hour. Included in this episode are discussions about the boutique guitar pedal market and the realities of discarded technology that took us to the moon.
Speaking of electronics podcasts, SolderSmoke is 10 years old now.
TARDIS-shaped guitars are nothing new, but [Gary] from the LVL1 hackerspace in Louisville, KY is making an acoustic one. The neck is, of course, taken from another guitar but the entire TARDIS-shaped body is custom-made. Now do resonance calculations on something that’s bigger on the inside.
Think German-made means German quality? [AvE], [Chris], or whatever we call him did a teardown of a Festool Track Saw. It’s a thousand dollar tool that will start to stink in a few years and has bearings that don’t make any sense.
Love 8-bit? There’s a Kickstarter from 8-bit generation for a documentary about the love, loss, resurrection and continuation of old computers. Dozens of very interesting interviews including one from our own [Bil Herd]
We’re going to build an electronic Hackaday Badge, and by “we”, I mean Hackaday community members who are passionate about the project.
I’ll be leading the charge. I had a great learning experience the last time I helped design the e-paper badge for the 2013 Open Hardware Summit, and hope to learn a lot along the way this time too. Since then, Badges have come a long way – at cons like DEFCON, LayerONE, Shmoocon, The Next Hope, Open Hardware Summit, The EMF, SAINTCON, SXSW Create, The Last Hope, TROOPERS11, ZaCon V and of course the rad1o from this year’s CCCamp. Word is that this year’s Open Hardware Summit badge is going to be pretty kickass too. So, we have some very big shoes to fill. But this doesn’t have to be about “my badge is better than yours”. And this badge isn’t meant to be specific to any single con or event. So what does the Badge do, then? “It’s a physical extension of the hackaday.io community, made specifically for hacker gatherings of all types and sizes.”

A team at the École Polytechnique Fédéral de Lausanne has developed and built a quadcopter with arms that unfold just before takeoff. The idea is that you can fold the device back up when you’re done with it, making it possible to store a bunch more of the quads in your backpack for instance.
The unfolding mechanism relies on the torque of the rotors spinning up to swing the arms into place. Once fully extended, a spring-loaded flap folds up, catches on some magnets, and forms an L-shaped structure that won’t re-fold without human intervention.
Under normal flying conditions, quads have a two left-handed propellers and two right-handed ones and the motors spin in opposite directions. In order to do the unfolding, two of the motors need to run essentially in reverse until the frame has clicked into place. They use a sensor (Hall effect?) to detect the arm locking, and then the rotors quickly switch back to their normal rotation before the quad hits the floor. In the video, they demonstrate that they’ve got this so well tuned that they can throw it up into the air to launch. Wow.
Everything’s still in prototype phase, and one of the next goals is “strengthening the arms so they can withstand crashes”, so don’t expect to see these in your local hobby store too soon. In the mean time, you’ll be able to see them in the flesh if you head up to the IEEE International Conference on Robotics and Automation in Seattle that started today and runs through Friday. If anyone goes, take more video and post in the comments?

If you’d like to spend four days learning from and picking the brains of a big group of well-known developers and open-source wizards for the low, low cost of absolutely free, keep reading.
The hack.summit() conference is a live, global event put on by the fine folks behind real-time programming assistance service hack.hands(). From December 1 to December 4, a wide range of speakers will present and answer democratically popularized questions over Crowdcast via Google+ Hangouts. Speakers in attendance include wiki inventor and Design Patterns pioneer [Ward Cunningham], Codeacademy founder [Ryan Bubinski], Google Glass creator [Tom Chi], Python Software Foundation’s [Alex Gaynor], and even the inimitable [Jon Skeet].
The goals for this conference are simple and admirable: to educate developers of all stripes about best practices, to encourage mentorship in the programming community, and to spread the joy of coding by supporting coding non-profits.
You can register for free simply by spreading the word through social media, but making a donation to the coding non-profit of your choice is definitely encouraged. There are many to great organizations to choose from such as CoderDojo (an easy choice for us). A tidy summary of the event is available at the hack.summit() FAQ(PDF).
I’ve developed or have been involved with a number of imaging technologies, everything from DIY synthetic aperture radar, the MIT thru-wall radar, to the next generation of ultrasound imaging devices. Imagery is cool, but what the end-user often wants is some way by which to get an answer as opposed to viewing a reconstruction. So let’s figure that out.
We’re kicking-off a discussion on how to apply deep learning to more than just beating Jeopardy champions at their own game. We’d like to apply deep learning to hard data, to imagery. Is it possible to get the computer to accurately provide the diagnosis?
I helped to organize a seminar series/discussion panel in New York City on November 13th (you know, for those readers who are closer to New York than to Munich). This discussion panel includes David Ferrucci (the guy who lead the IBM Watson program), MIT Astrophysicist Max Tagmark, and the person who created genetic sequencing on a chip: Jonathan Rothberg. As the vanguard of creativity and enthusiasm in everything technical we’d like the Hackaday community to join the conversation.

It is with great pleasure that we are able to announce the final slate of speakers for Hackaday’s 10th Anniversary on October 4th in Pasadena. There are still around 30 tickets left for the conference so get yours now!
The most recently confirmed speaker is a man of many names. [Ryan Clarke] may be better known as [LosT], [1o57], or [Lostboy]. For years he has been driving the flagship contest at DEFCON by generating cryptographic puzzles that run far and deep through the 4-day conference and beyond. His talk will venture into the art and science of putting together these challenges, and the lengths at which determined hackers will go to solve them. His site gets taken over each year for DEFCON, so you might want to explore his Twitter account if you’re looking to learn more about this mysterious figure.
The other four speakers have already been mentioned in the initial announcement and last week’s follow-up. [Steve Collins] will discuss how his early interest in hacking led him to become an engineer at NASA. [Quinn Dunki] will have her scratch-built Veronica computer on hand and explain the adventure of the impressive project. [ThunderSqueak] will help us wrap our minds around the concept of non-binary computing, and [Jon McPhalen] will present the benefits of multi-core embedded processing versus traditional interrupt-based design.
We can’t wait for this amazing afternoon of talks which is just one week from Saturday. We hope to see you there!
