Adafruit And The Arduinos At Maker Faire

The apparent lull on the Arduino front the last few weeks was just the calm before the storm that is the Bay Area Maker Faire (BAMF). Both companies claiming the Arduino name were there over the weekend, with news and new products in tow. Ironically, you could see from one booth straight over to the other. Small world.

Perhaps the biggest news from Arduino LLC is that hacker-friendly Adafruit is now going to be making officially-licensed boards in the US. Competing with this news, Arduino SRL brought its new boards, including the Yun Mini and ARM-powered Arduino M0. And [Massimo Banzi] and Arduino LLC seem to be taking an end-run around the Arduino SRL trademark by announcing the “Genuino” brand for European production. For all the details, read on!

The Adafruit Connection

As announced by [Massimo] in his “State of the Arduino” keynote speech at the BAMF, Arduino is licensing Adafruit to produce a range of the “most-requested” Arduino boards at their factory in New York. So those of you looking to support Arduino LLC with your purchases also get to help line [Ladyada]’s pockets at the same time. That’s a big win in our book.

It’s not a complete surprise that Adafruit should get tapped as a US fab for Arduino.cc. They’ve been selling the boards and producing copious Arduino-related tutorials since their beginnings in 2005. More recently, Adafruit partnered with Arduino LLC to create the Gemma board, which is basically an ATTiny85-based Arduino-a-like in a tiny round, wearable-friendly board. (If you’re familiar with the Adafruit lineup, it’s essentially a Trinket in the round format of a LilyPad Arduino.)

Indeed, after the deal is done and the dust has settled, it’s a bit surprising to us that this hasn’t happened earlier, what with both Adafruit and Sparkfun producing licensed boards and Arduino LLC looking for new manufacturers. Anyway, good job Adafruit and Arduino (LLC)!

(New) Hardware from Arduino SRL

Arduino SRL had its Yun Mini, which is essentially a smaller version of the Yun — a mashup of an Arduino Leonardo with an OpenWRT-capable router chipset. We’ve reported on these previously but it’s fun to see them in the flesh.

The M0 is interesting. Before the troubles began, Arduino designed an ARM-M0+ based board with Atmel. Now Arduino LLC has it listed on their website as the Arduino Zero, but still hasn’t got any for sale yet. Arduino SRL has the boards on their website as the Arduino Zero Pro, with a different name, but is now touting this version as the “M0 Pro”. What’s in a name? Not much. The circuit layouts and parts appear identical.

The Portal Battle

Both of the Arduino companies are working on getting your Arduino development into “the cloud”. (Conscience compels us to note that “the cloud” is actually just other people’s computers.) Anyway, this essentially means new web-based and browser-based versions of the IDE that tie into web services. Interestingly enough, the two companies have different takes on what that entails.

According to their Maker Faire press release, Arduino SRL will be launching a web portal for makers to “promote and distribute their products” and share code and ideas. Located at my.arduino.org (which currently seems to be password-access only), the idea seems to be to create a mini-Tindie for Arduino-based products. This couples with their “Arduino IDE-alpha”, a JavaScript-based IDE that will run in the browser.

Meanwhile, Arduino LLC displayed previously announced their alternative development platform, Arduino Create. Arduino Create lets you write, compile and upload sketches “directly from the browser with the Arduino Web Editor”, and store your code in the “Arduino Cloud”. Arduino Create looks slick: certainly a lot better than the homely Java IDE that we’re all used to. It’s too early to tell what this “cloud” is all about, but it looks like it will include code sharing, schematic and wiring hookup storage, and easy sharing among users.

We already use blogs, Hackaday.io (shameless plug!), Github, and other “cloud” services to store our projects and code, so we’re not entirely sure what either of these portal offerings will bring to the table. It’s 2015, is anyone still hurting for project hosting space on the web?

Cynically, we note that both of these companies are in a battle to “own” the Arduino community and that getting people to host code and projects on their servers is an obvious strategy, and providing a web-based IDE to facilitate this capture is the tactic.

And before we leave “the cloud”, we should note that both Arduinos are late to the game. codebender has been around and programming Arduinos on the web since 2012.

New Names

Finally, as if it weren’t bad enough with Arduino LLC and Arduino SRL, [Massimo Banzi] also announced that licensed boards for the European market will be sold under the new “Genuino”.

Actually, this is a pretty cagey maneuver, because it side-steps the European trademark issues (which [Massimo] referred to as “the bullsh*t” in his talk) and is a cute name to boot. “Genuine”, get it?

Our take? As [Massimo] almost said in this video interview with Make, “a rose by any name would smell as sweet.” If Arduino LLC loses the trademark lawsuit in Italy, they’ll not be allowed to sell boards using the “Arduino” name. The best way to limit the damage in the future is to make the switch now, while everyone is watching, and give the market time to adapt.

Large Seven-Segment Clock Build Takes Time To Perfect

[Kevin Rye] built a discrete TTL based seven-segment clock, and he wasn’t too happy with the ugly insides compared to the nice enclosure he built for it. He embarked on creating another large seven-segment clock to put inside that enclosure.

Clocks, and specifically seven-segment based ones, aren’t anything new to write about. This particular project, which is still work in progress, is interesting. [Kevin] is an experienced hacker, but the problems he encountered and resolved along the way could prove useful to a fellow hacker someday.

To start with, he tried rectifying his old build. But in his own words “You can polish a turd, but it’s still a turd.” Five years later, he’d had enough. He’s built a lot of other clocks, but rather than repurposing them, he decided to start from scratch. He quickly breadboarded an Arduino, some displays and drove them using the Multiplex7seg library. That library supports only four characters, so he was back to the drawing board. With a fresh start, his design is now moving along nicely. For now, he’s designed three boards for the display, two boards for the colons between digits, the main Arduino-clone controller board and a 3D printed front frame to hold the displays. It will be nice to finally see that enclosure receive some fitting occupants and bring this build to closure.

Hackaday Links: May 17, 2015

Here’s a worthwhile Kickstarter for once: the Prishtina Hackerspace. Yes, that’s a Kickstarter for a hackerspace in Kosovo. Unlike most hackerspace Kickstarters, they’re already mostly funded, with 20 days to go. If we ever get around to doing the Istanbul to Kaliningrad hackerspace tour, we’ll drop by.

Codebender is a web-based tool that allows you to code and program an Arduino. The Chromebook is a web-based laptop that is popular with a few schools. Now you can uses Codebender on a Chromebook. You might need to update your Chromebook to v42, and there’s a slight bug in the USB programmers, but that should be fixed in a month or so.

Here’s a great way to waste five minutes. It’s called agar.io. It’s a multiplayer online game where you’re a cell, you eat dots that are smaller than you, and bigger cells (other players) can eat you. [Morris] found the missing feature: being able to find the IP of a server so you can play with your friends. This feature is now implemented in a browser script. Here’s the repo.

The FAA currently deciding the fate of unmanned aerial vehicles and systems, and we’re going to live with any screwup they make for the next 50 years. It would be nice if all UAV operators, drone pilots, and everyone involved with flying robots could get together and hash out what the ideal rules would be. That’s happening in late July thanks to the Silicon Valley Chapter of AUVSI (Association for Unmanned Vehicle Systems International).

SOLAR ROADWAYS!! Al Jazeera is reporting a project in the Netherlands that puts solar cells in a road. It’s just a bike path, it’s only 70 meters long, and it can support at least 12 tonnes (in the form of a ‘fire brigade truck’). There’s no plans for the truly dumb solar roadways stuff – heating the roads, or having lanes with LEDs. We’re desperately seeking more information on this one.

Arduino Announces Manufacturing Partnership with Adafruit


Today, May 16th, 2015 Massimo Banzi, CEO and co-founder of Arduino, announced at Maker Faire during the “State of Arduino” keynote that Adafruit is manufacturing Arduino’s for Arduino.cc in New York, New York, USA! 

Limor “Ladyada” Fried said:

“Adafruit and Arduino.cc have been working together on open-source software and hardware for almost 10 years in a variety of ways, this is expanded partnership and manufacturing is part of our collective goal to make the world a better place through the sharing of ideas, code and hardware with our communities –

We’re currently manufacturing the Arduino  Gemma with Arduino.cc right here in New York City at the Adafruit factory, it instantly became a top seller and we’re looking forward to bringing our manufacturing expertise and processes to start shipping Arduinos right here from the USA as soon as possible!”

Take a look at this video interview of Massimo by Make directly from Maker Faire Bay Area and containing other important announcements:

Combination locks are no match for this Arduino-powered cracker

If you need a reminder not to put your complete trust in standard combination locks, here it is. Samy Kamkar, who once also engineered software that can hijack drones, created a motorized lock-cracking device called "Combo Breaker." We don't exactly know what he's going to use it for, but it's capable of going through each combination in less than two seconds and can crack a lock open in no time. Kamkar created two versions of the device: one is smaller and slightly less powerful than the other, but both are equally effective, in part thanks to their Arduino microprocessors. Before you head out in search of a better lock, though, watch Kamkar explain how he built the machines after the break.

Vacuum Gauge Display; Arduino Replaces Industrial

Arduinos! They’re a great tool that make the world of microcontrollers pretty easy, and in [cptlolalot]’s case, they also give us an alternative to buying expensive, proprietary parts. [cptlolalot] needed a gauge for an expensive vacuum pump, and rather than buying an expensive part, built a circuit around an Arduino to monitor the vacuum.

This project goes a little beyond simple Arduino programming though. A 12V to 5V power supply drives the device, which is laid out on a blank PCB. The display fits snugly over the circuit which reduces the footprint of the project, and the entire thing is housed in a custom-printed case with a custom-printed pushbutton. The device gets power and data over the RJ45 connection so no external power is needed. If you want to take a look at the code, it’s linked on [cptlolalot]’s reddit thread.

This project shows how much easier it can be to grab an Arduino off the shelf to solve a problem that would otherwise be very expensive. We’ve been seeing Arduinos in industrial applications at an increasing rate as well, which is promising not just because it’s cheap but because it’s a familiar platform that will make repairs and hacks in the future much easier for everyone.

Casa Jasmina and Bruce Sterling at Thingscon 2015

Bruce Sterling went to Thingscon conference with a keynote about Casa Jasmina and then published the following essay.

—————-

This is the third of my Casa Jasmina essays. It’s about the recent “ThingsCon” conference in Berlin, May 2015.

This remarkable event was the second “ThingsCon,” a new gathering which makes itself useful to the European hardware startup scene, especially “connected products” designers and builders from Berlin and London. “ThingsCon” took place in Berlin’s “Culture Brewery,” which is a huge, defunct beer factory, currently re-zoned for theaters, bars, restaurants and design retail.

Anybody who has seen the Garrone Foundry (which houses Toolbox Co-Working, Fab Lab Torino and Casa Jasmina), would surely recognize the “Culture Brewery.” It’s the same European story: the old industrial hulk remade for today’s culture-industry. So we found the ThingsCon venue to be pretty cozy, even though the stairs are of odd sizes, the huge, lofty rooms don’t fit together properly, the events and workshops are on different floors and mysteriously distant from one another, and there was excellent beer everywhere and tiny, crooked bathrooms stuck nowhere in particular. There’s something fun about this steampunk disorganization — if you’ve built a weird open-source Internet-of-Things device out of glued plywood and steel rods, it really fits that atmosphere.

ThingsCon is not a Maker Faire for the general public, and attending it is not cheap. ThingsCon is aimed at designers, developers, engineers, entrepreneurs and similar stakeholder-types from the technology ecosystem. The presentations were full of practical wisdom about commercial tech-product development: scaring up funding money, allocating time and resources, packaging, promotion, marketing, founder exit-strategies, angel investment, the issues common to people who might like to sit down for a serious talk with, say, Intel.

The organizers of ThingsCon are Peter Bihr, Simon Hoher, Emanuel Schwarz, Max Kruger, Sonja Heinen, Alexandra Deschamps-Sonsino, Brady Forrest, Louisa Heinrich, and Marcel Schouwenaar. As conference organizers go, they won’t win any prizes for sleek efficiency. However when it comes to the Internet of Things, these activists know plenty. At ThingsCon you can learn a lot in a hurry.

So: now that we understand what ThingsCon is about and who ThingsCon is meant to please, let’s confront some of their native ThingsCon problems, because they have lots of interesting issues.

The guy who delivered the first ThingsCon opening keynote, Warren Ellis, really understands their pains. Warren Ellis is pretty well known as a comic book writer, film scriptwriter and novelist, but he was also in the brain-trust of BERG,the legendary and now-dead London interaction-design firm. Warren Ellis grasps the many thorny difficulties of modern connected-product design.

Ellis delivered a sardonically funny rant, warning designers, engineers and manufacturers about the fierce wrath of genuine consumers. Consumers — (they’re the people who are supposed to buy Internet-of-Things products) — are a fickle and treacherous group. Consumers are never grateful for the hard work of designers and technicians. On the contrary, consumers are suspicious, endlessly demanding of customer support, and they resent most things they buy. The Internet-of-Things is even worse than traditional consumer capitalism, because interactive products don’t just sit there, they are invasive and intimate. People treasure their homes as a safe space in a harsh, competitive world, and they feel emotionally wounded when anything in their house betrays them.

Warren Ellis is an intelligent and erudite man, and he was telling the crowd the truth, but they were all laughing nervously because they can’t really believe what he says. It’s all true, but it’s important to understand this and still have some courage about it. If you invent and manufacture something, and it’s a commercial success and ten million people buy the product, of course your life is going to change. You won’t be a “Maker” alone in a garage any more, you’ll be an Internet multimillionaire with customer-support issues. Warren Ellis is right to urge people to think these things through: you shouldn’t dabble in technology and business unless you’re ready to face the consequences of getting what you want.

Barriers to entry in manufacturing are collapsing, so the old lines between a do-it-yourself Maker and a commercial industrialist are blurring. But this doesn’t solve old problems, it just creates interesting new ones. This was the lesson conveyed by Tina Aspiala. Before ThingsCon 2015, I had never heard of Tina Aspiala. Thanks to ThingsCon, I will pay attention to Tina Aspiala from now on.

Tina, who achieved some success with a product of hers, has become a Kickstarter patroness. Tina Aspiala spends a lot of time on Kickstarter and likes to give people some crowdfunding money just to see what happens. She told the crowd that results were mixed. Kickstarter is a funding platform, but some people on Kickstarter are crooks, they’re Kickstarter embezzlers. Other people want to be honest, but they flee in terror when they realize what the real world expects from real design and manufacturing. Others just have bad luck with their Kickstarter: they really wanted to do the work, but they broke a leg, or Dad died, or there was a divorce… that mishap wouldn’t stop FIAT or General Electric, but it does stop the Kickstarter team because they are few in number, while FIAT and General Electric have thousands of personnel.

Many Kickstarter projects get built, despite the host of problems in shipping, supply chains, material costs and manufacturing — but that doesn’t end the story. The product might be workable, but just not much good. The product might do what is promised, but the thing that the product does is only interesting once or twice, not useful in daily life. It’s a “gonzo product” (in the term created by Alexandra Deschamps-Sonsino), because it physically works and it does something, but the thing it does is eccentric and weird, so it has no commercial potential or mass appeal.

Why do we have “gonzo products” nowadays? It’s because (as Tina Aspiala pointed out), cheap electronic components make new combinations easy. Projectors, motors, sensors, cameras, processors and various wireless connectivity chips are all drastically cheaper, so product development becomes like a card game, when any gambler can connect X with Y and add some Z, then hope for a jackpot payoff.

In the case of the Internet of Things, there are many possible inputs — dozens of sensors of all kinds — but very limited outputs, because most IoT gizmos can only do very limited things to get any human attention: they blink, or beep, or vibrate. Blinking, beeping, vibrating things that demand human attention can get pretty annoying. Clearly this is a major IoT problem. Tina Aspiala recommends trying to think this situation through with some design perspective, instead of just hacking more components and attaching them to breadboards with soldering irons. That’s a point of view that makes some sense, though, let’s face it, people are gonna want to do it the easy way.

ThingsCon abounded in talks and workshops, more than I can describe here, but the most interesting thing on offer at Thingscon 2015 was the “IOT Design Manifesto”.  That’s why I’m placing the manifesto here in this post.


A manifesto is a sign of creative health. It’s not that I agree with the “IoT Design Manifesto” — on the contrary, if everybody agrees with a manifesto, then the manifesto is vapid and useless and hasn’t really said anything. Even a manifesto that’s completely wrong can be useful, because it motivates people to rebel and try something else. This manifesto is pretty good, in my opinion, because it’s kindly in tone and well-mannered, it confronts quite a few of the IoT’s real problems.

Even the first declarations, one and two, “We don’t believe the hype, we design useful things,” singles out the ThingsCon crowd as people who are skeptical and yet also trying to get something done. It’s a good attitude for a young industry. The other declarations are about about participation, security, privacy, data collection, association, personal agency, sustainability and humanity. These are some big, hairy issues which aren’t going to get solved in anybody’s lifetime. However, if you spend your life with the Internet of Things you’re going to be dealing with situations of that kind all the time. So, might as well get used to that prospect now.

The authors of this IoT Manifesto are Andrew Spitz, Ruben van der Vleuten, Marcel Schouwenaar, Harm van Beek, Kevin Verelst, Anner Tiete, Jan Belon, Marcel van Heist and Holly Robbins. Before I went to ThingsCon I’d never heard of any of those people, but they were right to do what they did, and I’ll be watching them with a lot more interest from now on. People tend to grow by the size of their chosen problems. These people have some pretty big problems.

I closed the ThingsCon event by asking the people there to help us with our house.

It’s a bit scary to open the faucet in this way: we don’t know if we’ll get a huge flood, or just a groan in the pipe and some dripping. If we get a lot of interest, Casa Jasmina will be crowded and noisy; if interest is more modest, we’ll try to concentrate on a few core issues. In our Internet-of-Things house, we’ll have to acquire some things, accept some things, build some things and maybe commission some things, too. The project has started deliberately, we have paced ourselves, but as the months pass, Casa Jasmina will slowly become a unique and interesting place, a true place of difference.

I wondered, in starting this project, who would ever really want to stay in such a place, and, having been to ThingsCon, I now have a much better idea about that. ThingsCon had about 300 people attending it — the “new hardware movement” are not a mass movement of millions — but those three hundred people are real people. They are bright and committed, and they really exist. If we understand them as our natural guests and we try to please them, I think we’ll do well.
