Back in the olden days, when the Wire library still sucked, the Arduino was just a microcontroller. Now, we have single board computers and cheap microcontrollers with WiFi built in. As always, there’s a need to make programming and embedded development more accessible and more widely supported among the hundreds of devices available today.

At the Embedded Linux Conference this week, [Massimo Banzi] announced the beginning of what will be Arduino’s answer to the cloud, online IDEs, and a vast ecosystem of connected devices. It’s Arduino Create, an online IDE that allows anyone to develop embedded projects and manage them remotely.

As demonstrated in [Massimo]’s keynote, the core idea of Arduino Create is to put a connected device on the Internet and allow over-the-air updates and development. As this is Arduino, the volumes of libraries available for hundreds of different platforms are leveraged to make this possible. Right now, a wide variety of boards are supported, including the Raspberry Pi, BeagleBone, and several Intel IoT boards.

The focus of this development is platform-agnostic and focuses nearly entirely on ease of use and interoperability. This is a marked change from the Arduino of five years ago; there was a time when the Arduino was an ATmega328p, and that’s about it. A few years later, you could put Arduino sketches on an ATtiny85. A lot has changed since then. We got the Raspberry Pi, we got Intel stepping into the waters of IoT devices, we got a million boards based on smartphone SoCs, and Intel got out of the IoT market.

While others companies and organizations have already made inroads into an online IDE for Raspberry Pis and other single board computers, namely the Adafruit webIDE and Codebender, this is a welcome change that already has the support of the Arduino organization.

Today, at Embedded Linux Conference 2018, Arduino announced the expansion of the number of architectures supported by its Arduino Create platform for the development of IoT applications. With this new release, Arduino Create users can manage and program a wide range of popular Linux® single-board computers like the AAEON® UP² board, Raspberry Pi® and BeagleBone® as if they were regular Arduino boards. Multiple Arduino programs can run simultaneously on a Linux-based board and interact and communicate with each other, leveraging the capabilities provided by the new Arduino Connector. Moreover, IoT devices can be managed and updated remotely, independently from where they are located.

To further simplify the user journey, Arduino has also developed a novel out-of-the-box experience for Raspberry Pi and BeagleBone boards, in addition to Intel®  SBCs, which enables anyone to set up a new device from scratch via the cloud without any previous knowledge by following an intuitive web-based wizard. Arduino plans to continue enriching and expanding the set of features of Arduino Create in the coming months.

“With this release, Arduino extends its reach into edge computing, enabling anybody with Arduino programming experience to manage and develop complex multi-architecture IoT applications on gateways,” said Massimo Banzi, Arduino CTO. “This is an important step forward in democratizing access to the professional Internet of Things.”

“At Arduino we want to empower anyone to be an active player in the digital world. Being able to run Arduino code and manage connected Linux devices is an important step in this direction, especially for IoT applications that need more computing power, like AI and computer vision,” added Fabio Violante, Arduino CEO.

The CAN bus has become a defacto standard in modern cars. Just about everything electronic in a car these days talks over this bus, which makes it fertile ground for aspiring hackers. [Daniel Velazquez] is striking out in this area, attempting to decode the messages on the CAN bus of his Smart ForTwo.

[Daniel] has had some pitfalls – first attempts with a Beaglebone Black were somewhat successful in reading messages, but led to strange activity of the car and indicators. This is par for the course in any hack that wires into an existing system – there’s a high chance of disrupting what’s going on leading to unintended consequences.

Further work using an Arduino with the MCP_CAN library netted [Daniel] better results, but  it would be great to understand precisely why the BeagleBone was causing a disturbance to the bus. Safety is highly important when you’re hacking on a speeding one-ton metal death cart, so it pays to double and triple check everything you’re doing.

Thus far, [Daniel] is part way through documenting the messages on the bus, finding registers that cover the ignition and turn signals, among others. Share your CAN hacking tips in the comments. For those interested in more on the CAN bus, check out [Eric]’s great primer on CAN hacking – and keep those car hacking projects flowing to the tip line!

[Kratz] just turned into a rock hound and has a bunch of rocks from Montana that need tumbling. This requires a rock tumbler, and why build a rock tumbler when you can just rip apart an old inkjet printer? It’s one of those builds that document themselves, with the only other necessary parts being a Pizza Hut thermos from the 80s and a bunch of grit.

Boot a Raspberry Pi from a USB stick. You can’t actually do that. On every Raspberry Pi, there needs to be a boot partition on the SD card. However, there’s no limitation on where the OS resides,  and [Jonathan] has all the steps to replicate this build spelled out.

Some guys in Norway built a 3D printer controller based on the BeagleBone. The Replicape is now in its second hardware revision, and they’re doing some interesting things this time around. The stepper drivers are the ‘quiet’ Trinamic chips, and there’s support for inductive sensors, more fans, and servo control.

Looking for one of those ‘router chipsets on a single board’? Here you go. It’s the NixCoreX1, and it’s pretty much a small WiFi router on a single board.

[Mowry] designed a synthesizer. This synth has four-voice polyphony, 12 waveforms, ADSR envelopes, a rudimentary sequencer, and fits inside an Altoids tin. The software is based on The Synth, but [Mowry] did come up with a pretty cool project here.

Give your board a lift by adding legs built from off-the-shelf hardware.
