Arduino SRL To Distributors: “We’re The REAL Arduino”

March 28, 2015 by Elliot Williams 200 Comments

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

A 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

A 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.

Playing Space Invaders With Real Fire And Lasers

March 25, 2015 by Sarah Petkus 16 Comments

Making a Space Invaders game is up there on the list of most unconventional things you could do with a laser cutter. In watching the tiny little ships burst into flames, [Martin Raynsford’s] modification has got to be one of the more dangerous looking ones we’ve seen as well.

[Martin] always had the desire to make a tangible version of the classic game. Since his Whitetooth A1 laser cutter already contained the bulk of the moving hardware needed, not to mention an actual high powered laser to “pew pew” with, he decided it was the perfect starting point for such a project. The game is played looking down into the cutter since the laser of course fires in that direction, however a basic webcam is mounted to the laser assembly so that you can view the game on a computer screen at the proper perspective. An Arduino Mini is responsible for stepper control, allowing the player to jog back and forth and fire with a keyboard. [Martin] added an extra gear to the z-axis bed-leveler so that it could drive rows of paper invaders left and right across the bottom. Paperclips wedged into slots along a modified backboard hold each of the paper slips in place. This works ideally since they can be reloaded easily and won’t be maimed during use.

Due to the heat of the laser, landing a well positioned shot will likely nuke all of the nearby invaders as well, making for a theatrical inferno and easy win. Now to step up the difficulty level and figure out how to make them fire back…

Control Stuff With Your Muscles

March 23, 2015 by Will Sweatman 17 Comments

[David Nghiem] has been working with circuitry designed to read signals from muscles for many years. After some bad luck with a start-up company, he didn’t give up and kept researching his idea. He has decided to share his innovations with the hacker community in the form of a wearable suit that reads muscle signals.

It turns out that when you flex a muscle, it gives off a signal called a Surface ElectroMyographic signal, or SEMG for short. [David] is using an Arduino, digital potentiometer and a bunch of op amps to read the SEMG signals. LEDs are used to display the signal levels.

The history behind [David’s] project dates back to the late twentieth century, which he eloquently points out – “Holy crap that was a long time ago”. He worked with the MIT Aero Astro Lab and the Boston University Neuromuscular Research Center where he worked on a robotic arm for astronauts. The idea being to apply an opposing force to the arm to help prevent muscle deterioration.

Be sure to check out [David’s] extensive and well documented work, along with the several videos showing his projects at various stages of completion. If this gives you the electromyography bug, check out this guide on detecting the signals and an application of the concept for robotic prosthesis.

Enigma Machine Wristwatch

March 23, 2015 by Mike Szczys 12 Comments

We don’t find smartwatches to be supremely usable yet. This one sets a definition for usefulness. The Enigma machine is of course the cipher process used by the Germans during World War II. This Enigma Machine wristwatch is not only functional, but the appearance is modelled after that of the original machine. With the speckled gray/black case and the Enigma badge branding [Asciimation] has done a fine job of mimicking the original feel.

Driving the machine is an Arduino Pro Mini. We’ve seen Arduino Enigma Machines in the past so it’s not surprising to see it again here. The user interface consists of an OLED display at 128×64 resolution, three buttons, with a charging port to the right and on/off switch on the left.

The device is demonstrated after the break. Quite a bit of button presses are used to set up each of the three encoder wheels. But that’s hardly avoidable when you’re not committing to a full keyboard. We’re pretty impressed by the functionality of [Asciimation’s] interface considering it’s hardware simplicity.

This seems perfect for kids that are proving to have an interest in engineering. They learn about ciphers, embedded programming, and mechanical design and crafting (this is a hand-sewn leather wristband). Of course if you build one and start wearing it into the office we won’t judge.

Take A Spin On This Voice-Controlled 3D Scanning Rig

March 22, 2015 by Theodora Fabio 7 Comments

[Aldric Negrier] wanted to make 3D-scanning a person streamlined and simple. To that end, he created this voice-controlled 3D-scanning rig.

[Aldric] used a variety of hacking skills to make this project, and his thorough Instructable illustrates this nicely. Everything from CNC milling to Arduino programming to 3D-printing was incorporated into the making of this rig. Plywood was used to construct the base and the large toothed gear. A 12″ Lazy Susan bearing was attached to this gear to allow smooth rotation. In order to automate the rig, a 12V DC geared motor was attached to a smaller 3D-printed gear and positioned on the base. When the motor is on, the smaller gear’s teeth take the larger gear for a spin. He used a custom dual H-bridge motor driver made by a friend, which is connected to an Arduino Nano. The Nano is also connected to a Bluetooth module and an ultrasonic range finder. When an object within 1-35cm is detected on the rig for 3 seconds, the motor starts to spin, stopping when the object is no longer detected. A typical scan takes about 60 seconds.

This alone would have been a great project, but [Aldric] did not stop there. He wanted to be able to step on the rig and issue commands while being scanned. It makes sense if you want to scan yourself – get on the rig, assume the desired position, and then initiate the scan. He used the Windows speech recognition SDK to develop an application that issues commands via Bluetooth to Skanect, a 3D-scanning software. The commands are as simple as saying “Start Skanect.” You can also tell the motor to switch on or off and change its speed or direction without breaking form. [Aldric] used an Asus Xtion for a 3D-scanner, but a Kinect will also work. Afterwards, he smoothed his scans using MeshMixer, a program featured in previous hacks.

Check out the videos of the rig after the break. Voice commands are difficult to hear due to the background music in one of the videos, but if you listen carefully, you can hear them. You can also see more of [Aldric’s] projects here or on this YouTube channel.

SXSW Create: Sparkfun Gives Kids Awesome Badges To Hack

March 19, 2015 by Mike Szczys 22 Comments

By far the most desirable booth for the crowds at SXSW Create was the Sparkfun quadrant. We call it a quadrant because they had a huge footprint approaching 1/4 the tented area, but it was well used. They brought a number of staff down to Austin in order to give away a legit electronic badge project they call BadgerHack.

We love badge hacking. LOVE IT! But South-by isn’t purely a hardware conference so the badges aren’t made of PCBs (for shame). Add to that, free entry to Create scores you a wristband but no badge.

This is the answer to that, a badge giveaway and build-off aimed at kids but cool enough to make me feel only slightly awful for accepting one when I pretty much knew they were going to run out before the final day was done.

The USB stick PCB is, as you guessed it, an Arduino compatible loaded up with an FTDI chip and an ATmega328p which they call the BadgerStick. Accompanying this is a multiplexed 8×7 LED matrix board. Solder the three pin headers and the battery holder leads, connect to the plastic badge using the supplied double-stick tape, and you have a badge that scrolls a message in LEDs.

What an awesome giveaway. I really like it that they didn’t cut corners here. First off, the kids will value the badge much more because they had to actually assemble it rather than just being handed a finished widget. Secondly, there is the USB to serial chip and USB footprint that means they can reprogram it without any extra equipment. And an LED matrix… come on that’s just a gateway drug to learning Wiring. Bravo Sparkfun and Atmel for going this route with your marketing bucks.

The badge activity rounded out with some hardware interfacing. There’s a 3-pin socket that attendees could plug into 4 different stations around the booth. Once done they received a coupon code for Sparkfun that scrolls whenever the badge is booted up. For some at-home fun, the writeup (linked at the top) for the BadgerHack firmware is quite good. It offers advice on changing what is displayed on the badge and outlines how to build a game of Breakout with just a bit of added hardware.

A Motor, An Arduino And A Whole Bunch Of Laser Cutting

March 16, 2015 by James Hobson 14 Comments

[Guido] was recently commissioned to build a kinetic sculpture for a client who wanted something unique. What he came up with is really awesome.

It’s called ORBIS: The Wooden Kinetic & Lighting Sculpture. It mounts to the wall and provides a focal point for the room – a bright flashy spinning one at that! Does it just stay there and do random things? Nope, of course not! [Guido] built it with a unique control box, two Arduino 2560’s and an Xbee to communicate between them.

He was told to design it using old and new technologies so he’s got a rotary phone dial on the side of the box which allows the user to change through the different modes.

Switches on top also let you change the color of the sculpture and the speed at which it moves around. Since it’s wireless it can be easily set on the coffee table and become an instant conversation starter.

See it in action after the break.
