Arduino Vs. Arduino: Arduino Won

October 1, 2016 by 89 Comments

For the last two years, Arduino LLC (the arduino.cc, Massimo one) and Arduino SRL (the arduino.org, Musto one) have been locked in battle over the ownership of the Arduino trademark. That fight is finally over. Announced at the New York Maker Faire today, “Arduino” will now go to Arduino Holding, the single point of distribution for new products, and a non-profit Arduino Foundation, responsible for the community and Arduino IDE.

Since early 2015, Arduino — not the Arduino community, but the organization known as Arduino — has been split in half. Arduino LLC sued Arduino SRL for trademark infringement. The case began when Arduino SRL, formerly Smart Projects SRL and manufacturers of the Arduino boards with a tiny map of Italy on the silk screen, began selling under the Arduino name. Arduino LLC, on the other hand, wanted to internationalize the brand and license production to other manufacturers.

While Arduino and Arduino have been tied up in court for the last few years, from the outside this has look like nothing else but petty bickering. Arduino SRL forked the Arduino IDE and bumped up the version number. Later, an update from SRL was pushed out to Amazon buyers telling them Arduino.org was the real Arduino. Resellers were in a tizzy, and for a time Maker Faires had two gigantic Arduino booths. No one knew what was going on.

All of this is now behind us. The open source hardware community’s greatest source of drama is now over.

I spoke with Massimo after the announcement, and although the groundwork is laid out, the specifics aren’t ready to be disclosed yet. There’s still a lot to work out, like what to do with the Arduino.org Github repo, which TLD will be used (we’re rooting for .org), support for the multitude of slightly different products released from both camps over the years, and finer points that aren’t publicly visible. In a few months, probably before the end of the year, we’ll get all the answers to this. Now, though, the Arduino wars are over. Arduino is dead, long live Arduino.

Very, Very Tiny X86 Systems

September 30, 2016 by 105 Comments

The most interesting market for Intel in recent years has been very, very small form factor PCs. ARM is eating them alive, of course, but there are still places where very small and very low power x86 boards make sense. The latest release from SolidRun is the smallest we’ve seen yet. The SolidPC Q4 is one of the smallest x86 implementation you can find. It’s based around the MicroSoM, a module even smaller than a Raspberry Pi, and built around a carrier board that has all the ports you could ever want from the tiniest PC ever.

The SolidPC Q4 is technically only a carrier board featuring a microSD slot, Displayport, HDMI 1.4B, two RJ45 ports with the option for PoE, three USB 3.0 Host ports, jacks for mic and stereo sound, and an M.2 2230 connector for a wireless module. The interesting part of this launch is the MicroSoM, a System on Module based on Intel’s Braswell architecture. Two models are offered, based on the quad-core Atom E8000 and the Pentium N3710. Both modules feature up to 8GB of DDR3L RAM and 4GB of eMMC Flash.

The size of these modules is 52.8mm by 40mm, or just a shade larger than the stick-of-gum-sized Raspberry Pi Zero.

The SolidPC isn’t intended to be a Raspberry Pi competitor. While those cheap ARM boards are finding a lot of great uses in industry, they’re no replacement for a small, x86 single board computer. The pricing for this module starts at $157 according to the product literature, with a topped out configuration running somewhere between $300 and $350, depending on options like a heatsink, enclosure, or power adapter. If you want a small single board computer with drivers for everything, there aren’t many other options: you certainly wouldn’t pick a no-name Allwinner board.

Distributed Censorship Or Extortion? The IoT Vs Brian Krebs

September 29, 2016 by 118 Comments

Now it’s official. The particular website that was hit by a record-breaking distributed denial of service (DDOS) attack that we covered a few days ago was that of white-hat security journalist [Brian Krebs]: Krebs on Security.

During the DDOS attack, his site got 600 Gigabits per second of traffic. It didn’t involve amplification or reflection attacks, but rather a distributed network of zombie domestic appliances: routers, IP webcams, and digital video recorders (DVRs). All they did was create HTTP requests for his site, but there were well in excess of 100,000 of these bots.

In the end, [Krebs’] ISP, Akamai, had to drop him. He was getting pro bono service from them to start with, and while they’ve defended him against DDOS attacks in the past, it was costing them too much to continue in this case. An Akamai exec estimates it would have cost them millions to continue defending, and [Brian] doesn’t blame them. But when Akamai dropped the shields, his hosting provider would get slammed. [Krebs] told Akamai to redirect his domain to localhost and then he went dark.

Homebrew Powerwall Sitting At 20kWh

September 29, 2016 by 128 Comments

Every now and then a hacker gets started on a project and forgets to stop. That’s the impression we get from [HBPowerwall]’s channel anyway. He’s working on adding a huge number of 18650 Lithium cells to his home’s power grid and posting about his adventures along the way. This week he gave us a look at the balancing process he uses to get all of these cells to work well together. Last month he gave a great overview of the installed system.

His channel starts off innocently enough. It’s all riding small motor bikes around and having a regular good time.  Then he experiments a bit with the light stuff, like a few solar panels on the roof.  However, it seems like one day he was watching a news brief about the Powerwall (Tesla’s whole-home battery storage system) and was like, “hey, I can do that.”

After some initial work with the new substance it wasn’t long before he was begging, borrowing, and haggling for every used 18650 lithium battery cell the local universe in Brisbane, Australia could sell him. There are a ton of videos documenting his madness, but he’s all the way up to a partly off-grid house with a 20kWh battery bank, for which he has expansion plans.

There’s a lot of marketing flim flam and general technical pitfalls in the process of generating your own non-grid electricity. But for hackers in sunny areas who want to dump those rays into local storage this is an interesting blueprint to start with.

New SuperCon Badge Is 40% Lighter And A Work Of Art

September 28, 2016 by 28 Comments

The 2016 Hackaday SuperConference is just around the corner and today we get a good look at the hardware badge. It was designed by [Voja Antonic] — a legend of hardware creation who will be at the conference. I like to think of him as the Woz of the Eastern Bloc, having designed the Galaksija computer. This badge is a beautiful example of embedded design. We’ll dive into all of the details after the break.

Get your ticket now for 48-hours of talks, workshops, the Hackaday Prize party, badge hacking,  and so much more.

Songbird, A Mostly 3D Printed Pistol That Appears To Actually Work

September 28, 2016 by 132 Comments

[Guy in a garage] has made a 3D printed gun that not only appears to fire in the direction pointed, it can also do it multiple times. Which, by the standard of 3D printed guns, is an astounding feat. He started with .22 rifle cartridges but has since upgraded and tested the gun with .357 rounds. The link above is a playlist which starts of with an in-depth explanation of the .22 version and moves through design iterations

This gun prints on a standard FDM printer. Other 3D printable guns such as the infamous Liberator or the 3D printed metal gun need more exotic or precise 3D printing to work effectively. The secret to this gun’s ability is the barrel, which can be printed in nylon for .22 cartridges, or in ABS plus a barrel liner for .22 and .357 caliber.

A barrel liner is one way to repair a gun that has aged and is no longer shooting properly. Simply put, it is a long hardened metal tube with rifling on the inside. Some guns come out of the factory with one, and a gunsmith simply has to remove the old one and replace it. Other guns need to be bored out before a liner can be installed.

The metal liner surrounded by plastic offers enough mechanical strength for repeat firings without anyone losing a hand or an eye; though we’re not sure if we recommend firing any 3D printed gun as it’s still risky business. It’s basically like old stories of wrapping a cracked cannon in twine. The metal tries to expand out under the force of firing, but the twine, which would seem like a terrible material for cannon making, is good in tension and when wrapped tightly offers more than enough strength to hold it all together.

This is also how he got the .357 version to work. The barrel slots into the gun frame and locates itself with a rounded end. However, with the higher energy from a .357 round, this rounded end would act as a wedge and split the 3D printed frame. The fix for this was simple. Glue it back together with ABS glue, and then wrap the end of the assembly with a cable tie.

This is the first 3D printed gun we’ve seen that doesn’t look like a fantastic way to instantly lose your hand. It’s a clever trick that took some knowledge of guns and gunsmithing to put together. Despite the inevitable ethical, moral, and political debate that will ensue as this sort of thing becomes more prevalent, it is a pretty solid hack and a sign that 3D printing is starting to work with more formidable engineering challenges.

Line Follower With No Arduino

September 27, 2016 by 40 Comments

There’s hardly a day that passes without an Arduino project that spurs the usual salvo of comments. Half the commenters will complain that the project didn’t need an Arduino. The other half will insist that the project would be better served with a much larger computer ranging from an ARM CPU to a Cray.

[Will Moore] has been interested in BEAM robotics — robots with analog hardware instead of microcontollers. His latest project is a sophisticated line follower. You’ve probably seen “bang-bang” line followers that just use a photocell to turn the robot one way or the other. [Will’s] uses a hardware PID (proportional integral derivative) controller. You can see a video of the result below.
