Hackaday Links: April 5, 2015

[Dino] found something pretty cool at Walmart. It’s a USB Lighter; basically a car cigarette lighter that’s powered by a battery and charged via USB. A few bucks will buy you a battery, charge controller, and USB plug that will deliver over 2 amps at 3.7 Volts.

Speaking of battery chargers, here’s something from [Thomas]. He works in a hospital, and the IV pumps have a terrible charging circuit. After a few dozen chargers, they’ll give a battery error on the screen. They’re not bad, only unbalanced. [Thomas] made a simple rig with a Tenergy battery charger to rebalance the packs. No link, but here’s a pic. It beats paying $34 for a new battery pack.

Those Silhouette Cameo blade cutters don’t get enough respect. You can make vinyl stickers or an Arduino-themed pop up card.

Retroreflective spraypaint. Volvo has developed something called Lifepaint. It’s for bicycles and bicycle riders. Apparently, it’s clear when you spray it on, but if you shine a light on it – from a car’s headlight – it will reflect back. Any cool ideas here?

The Art of Electronics, 3rd edition, is finally out. Didn’t we hear about this a few months ago? Yes, we did. It’s shipping now, though, and there’s a sample. It’s chapter nine, voltage regulation and power conversion.

Ah, April Fool’s. I’m still proud of the Prince post, but there were some great ones this year. RS Components had Henry the Hover Drone, but we really like the protoboard with ground planes.

The market wasn’t always flooded with ARM dev boards. For a while the LeafLabs Maple was the big kid on the block. Now it’s reached end of life. If only there were a tree whose name ended in ~ino…

Tube Map Radio and Denki Puzzles

Sometimes, awesomeness passes us by and we don’t notice it until a while later. This is from 2012, but it’s so friggin’ insane we just have to cover it even if it’s late. Yuri Suzuki is an installation artist who designed the Tube Map Radio and Denki Puzzles.

The Tube Map Radio is inspired by a diagram created by the original designer of the London Tube map, Harry Beck, which shows the lines and stations of the London Underground rail network as an annotated electrical circuit. Iconic landmarks on this map are represented by components relating to their functions, including a speaker where Speaker’s Corner sits, battery representing Battersea Power Station and Piccadilly Circus marked as Piccadilly Circuit. The work was commissioned by the Design Museum London, and the PCB layout was done by Masahiko Shindo (Shindo Denki Sekkei). The idea was to bring the electronics out of the “black box” and not just display it, but to have it laid out in a fashion that people could try to understand how it really works.

The other project called Denki Puzzles is equally remarkable. It’s a kit meant to teach electronics, using a set of snap-fit components. But instead of having all “bricks” or units of the same shape, the Denki Puzzles are a collection of printed circuit board pieces whose form indicate a particular function. Fit the pieces together as a sort of physical circuit diagram and you’ll be able to build working electronics. For example, the LED unit looks like a 8 pointed star, and the resistance unit looks like a resistance symbol. Check out some pictures and a video after the break

Arduino SRL to Distributors: “We’re the REAL Arduino”

Arduino SRL (formerly known as Smart Projects SRL) sent out a letter to its distribution partners yesterday. If you’ve been following along with the Arduino vs Arduino story (we’ve previously published two installments), the content isn’t entirely surprising; it’s essentially a tactical move to reassure their distribution channels that Arduino SRL is the “One True Arduino”. That said, there’s still some new tidbits buried inside. You can skip down to read the full text below, but here’s our take.

The Business History of Arduino

arduino_vs_arduino_tnA quick summary of the legal situation. Arduino LLC was formed in April 2008 by the original five founders to provide a corporate entity behind the Arduino project. Smart Projects SRL, controlled by one of the founders, was tasked with the actual production of the boards. It turns out that Smart Projects had trademarked the Arduino brand in Italy in December 2008, before Arduino LLC got around to filing in April 2009 in the USA. But everyone was friends, right? As long as the licensing fees keep flowing.

Fast-forward to September 2014, when Arduino LLC filed a lawsuit in Italy against Smart Projects claiming that they had infringed LLC’s trademark and that they had recently stopped paying licensing fees on their use of the Arduino name. In October, Smart Projects filed with the USPTO to revoke Arduino LLC’s trademark. In late 2014, Smart Projects changed its company name to Arduino SRL (a “Società a responsabilità limitata” is one form of Italian limited-liability company) and hired a new CEO, [Federico Musto].  Around the same time, Arduino SRL opened up the website arduino.org (different from long-existing arduino.cc) but with nearly identical style. In January 2015, Arduino LLC filed a lawsuit in the US, claiming their right on the Arduino name.

The Gist of it

In short, Arduino LLC has been working on developing the Arduino platform, software, and community while Smart Projects / Arduino SRL was the major official producer of the hardware for most boards. Both are claiming to “be” Arduino, and going after each other in court. So it’s not strange that Arduino SRL would like to try to keep its hold on the distribution channels. Which brings us to their letter to distributors.

March 27 Letter

Arduino-Distributor-Update-0A good portion of the letter reads to be a very carefully worded defense of why Arduino SRL is the true Arduino:

“Arduino Srl (aka Smart Projects Srl), as you know has been from the  beginning of the Arduino® project, the place where the ideas were turned into reality and into a business.”

This is of course strictly true — Smart Projects was certainly the largest manufacturer of Arduino boards. But it sidesteps the issue at hand in the trademark suits: whether they were simply a licensed producer of the boards or whether they’re “Arduino”.

Similarly, in the questions section of the letter, they ask if there are actually two “Arduino” product manufacturers, and answer “not really”. Of course, that’s true. Arduino LLC doesn’t manufacture boards, but exists to license their trademark out to fund development.

The only real news in the letter is that Arduino SRL is replacing its old distribution and logistics company, Magyc Now, with a new one named CC Logistics. Both Magyc and CC Logistics are named as defendants in the US lawsuit filed by Arduino LLC, so it’s unlikely that this change is due to legal fallout.

What this Means

In conclusion, Arduino SRL’s letter to its distributors seems to essentially follow the line of reasoning in their trademark lawsuit in the US against Arduino LLC: since Arduino SRL is doing the manufacturing and using the Arduino name, they’re the true Arduino. Whether or not this will stand up in court, or whether Arduino LLC can make its case that SRL was simply a licensed manufacturer, remains to be seen.

We’ve embedded the contents of the letter after the break. You can also download the original PDF.

Caption CERN Contest Enters Week 8

The Caption CERN Contest has been going great guns thanks to the community of users over on Hackaday.io. The contest just finished up its seventh week of finding funny captions for images which CERN has in their archives. CERN has decades of great photo documentation of their projects. Unfortunately they don’t know which project each image goes with, or who exactly is in the image. We’re helping them out where we can, by letting CERN know any information we can find on their photos. We’re also having some fun along the way, by giving out a T-Shirt for the best caption each week.

Here are some of the best quotes from week 7

The Funnies:

“Are Socks and Sandals acceptable safety equipment for the Demolition Pit? Yes, because these are Kelvar socks and Zylon sandals being testing. Quite uncomfortable, but these feet will survive a close proximity blast.” – [controlmypad]

“Check it out! One tube for each Ninja Turtle” – [OzQube]

“Before the LHC, hunting for the Higgs was much less glamorous.” – [Tachyon]

The winner of course is [Tim] with the featured image at the top of this article.

week6winrarIf [Tachyon] sounds familiar, that’s because he came up with the best caption back in week 6. Runners up for week 6 were:

“Damn Mario Brothers ….. ‘gotta save the princess’ How about watching where you’re going for once. – [Scott Galvin]

“Here at CERN, you don’t get shafted. You get tubed.” – [Rollyn01]

“Thank god the separator caught him. Another 50 meters, and he’d be nothing but quarks.” – [Curtis Carlsen]

Hackaday Prize Worldwide: Makers Asylum

Several weeks before we launched the Hackaday Prize 2015 officially, I was asked to set up a local event in Mumbai to help spread the word about the event to local Makers. Since I also help run a local maker space, Makers’ Asylum, we decided to have a Bring-a-Hack evening on March 21st at the Asylum.

It was a packed day at the Asylum. We had an Aeromodeling workshop in the morning. One bunch was building a quad bike from old bicycle frames, and another was doing something similar using PVC pipes. A third bunch was building a work table from a recycled wooden pallet. All this before we even hit lunch hour. I set up my OpenSelfie photobooth, and everyone quickly wolfed down a lunch of Biryani. We started off late in the afternoon with a quick round of introductions.

 

First up was Siji Sunny, who quickly setup his latest hack – an Intel Atom NUC running Ubuntu + a WiFi router and he had media streaming over the local network from his Phone. Something like AirPlay, but using open source software – ffmpeg, ffstream and ffserver.

SXSW Create: ATX Hackerspace Area

We had a wonderful time over the weekend at the 2015 SXSW Create. I was really excited to see that there was a very large area set aside for the Hackerspaces of the Austin area and they took full advantage of that. Most notably, ATX Hackerspace who had multiple tables and was drawing a huge crowd.

sxsw-atx-thereminThis table is a good example of the demonstrations on hand. Primarily It’s a collection of ultrasonic theremin. The classic theremin uses oscillator-based sound production (we’ve been running a series on that concept) with a set of antennas that uses your body’s proximity to tweak that signal. This version mimics the user interface but greatly simplifies the skillset needed to produce the instrument by swapping the antenna for an ultrasonic rangefinder and generating the audio digitally. The more astute viewer will have noticed the instrument being held. I neglected to ask about this but it sure looks like a Holophonor which is another great seed idea for your next project. Update: it’s a Hulusi.

sxsw-atx-solderingI do think it’s worth noting that ATX also set aside a lot of table-space for their members to actually work on building projects at the event. We’re big advocates of this rather than simply exhibiting finished projects. It doesn’t really matter what you’re working on; seeing a table covered with interesting parts and tools, being worked on by fun people obviously enjoy each other’s company is the core message of a Hackerspace… right?

I talk with [Gardner] about ATX in the video after the break, and make a quick loop around the display tables.

Arduino v Arduino: Part II

Since our last article covering the Arduino v. Arduino case, we’ve received a couple of tips, done some more digging, and learned a lot more about what’s going on. We thought it was time to share the story with you as it develops.

The Players

In short, there are two companies calling themselves “Arduino” at the moment. One, Arduino LLC was founded by [Massimo Banzi], [David Cuartielles], [David Mellis], [Tom Igoe] and [Gianluca Martino] in 2009, runs the website arduino.cc, and has been directing and releasing the code that makes it all work. Most of these folks had been working together on what would become the Arduino project since as early as 2005.

The other “Arduino” used to be called Smart Projects and was the manufacturing arm of the project founded and run by [Gianluca Martino]. Smart Projects changed their name to Arduino SRL in November 2014. (A “Società a responsabilità limitata” is one form of Italian limited-liability company.) They have been a major producer of Arduino boards from the very beginning and recently registered the domain arduino.org.

Around the time of the name change [Martino] sold his shares to a Swiss firm Gheo SA and [Federico Musto] was appointed CEO. Gheo SA is owned and directed by [Musto], who also runs a design consultancy based in the US and Taiwan called dog hunter, LLC.

dog hunter and [Musto] helped develop the Arduino Yun, a mashup of an Arduino with an OpenWRT-compatible WiFi router. dog hunter also runs the Linino.org website to support the Linux distribution that’s running on the router part of the Yun.

In short, on one side is Arduino LLC, run by the original Arduino Five and hosting arduino.cc. On the other is now called Arduino SRL, run by a former co-developer [Federico Musto] who bought out the largest producer of Arduino boards and opened up arduino.org.
