Samsung builds a Smart Bike



Designed by Italian frame-builder Giovanni Pelizzoli and student Alice Biotti, the Samsung Smart Bike is built around an aluminum frame that boasts curved tubes to soak up vibrations from riding on rough city streets.

As Gizmag’s Ben Coxworth reports, a rearview camera is located between the seat stays of the frame to stream live video feeds to a handlebar-mounted Samsung smartphone.

“There are four lasers built into the frame, that project a bike lane onto the road on either side of the bike, as it’s moving. Those lasers automatically come on as ambient light levels drop, as detected by the smartphone,” writes Coxworth.

“Additionally, an app on the phone uses GPS to make a note of routes that are often traveled by the cyclist. It then offers the option of notifying city officials of those routes, with the suggestion that they add officially-designated bicycle lanes.”

The frame is also equipped with a battery, Atmel based Arduino board, as well as WiFi and Bluetooth modules.

Embedded Developer features Atmel’s ATPL230A modem

Earlier this year, Atmel introduced the ATPL230A, a Power Line Communications (PLC) modem designed to implement the physical layer of the PRIME standard (Power Line Intelligent Metrology Evolution).

This month, the ATPL230A modem is featured in the June edition of EE Web’s Embedded Developer magazine. According to Atmel exec Kourosh Boutorabi, the ATPL230A offers OEMs a seamless and cost-efficient solution for smart metering platforms.

“Expanding on Atmel’s unique and highly flexible SAM4Cx platform, ATPL230A addresses the fifth pillar of [our] existing platform, the physical communication layer,” Boutorabi explained.

“Atmel’s ATPL230A can be paired with dual 32-bit ARM Cortex-M4 RISC processors to deploy an unprecedented level of integration and accuracy for single and multi-chip architecture options for system integrators and OEMs.”

The ATPL230A also boasts a class D line driver for PLC signal amplification, providing optimized signal injection efficiency by up to 62 percent.

Combined with low power sipping, this feature enables improved thermal behavior, extends long-term reliability and reduces overall power consumption. Meanwhile, new transmission modes and frequency band extensions facilitate robust power line communications.

As Boutorabi told the publication, Atmel is currently working with top tier customers worldwide who are developing multiple products for individual markets such as the Spanish, French or U.S. market.

“These customers need a supplier that addresses all their markets’ requirements. Our solution addresses 90 percent of all of these markets,” he said.

“Every utility has different communication requirements, so to be able to address all of these segments with one solution is a significant achievement.”

To help accelerate the design process for engineers, Atmel is currently offering the ATPL230A evaluation kit which can be used to test the ATPL230A’s smart metering capabilities with embedded PLC.

Recently, a Maker by the name of Vishalapr created an inexpensive POV display using an Atmel ATtiny85 microcontroller (MCU) paired with a DC motor.

Aside from the Atmel-based ATtiny85 and DC motor, additional key components include:

  • 5 LEDs
  • 3V coin cell
  • Coin cell holder
  • USB header (a normal USB cord would do)
  • A case/enclosure to keep the motor in
  • A piece of wood or cardboard for the LED bar
  • IC holder
  • Protoboard
  • Jumper cables

Vishalapr kicks off the project by making a simple LED board out of cardboard/wood. He then connects the ATtiny85 MCU and the motor/power supply, placing the various components in an enclosure.

Next up? Installing support for the ATtiny series and programming the ATtiny85.

“So now that you have built a 5 LED POV Display, why not try something bigger? How about a 10 LED POV Display with an Arduino instead of an ATTiny85 (supports only 5 outputs),” Vishalapr added.

“We can also make this wall mountable by adding a small hole through which you can hang it on a nail firmly. Using some tricolor LEDs and more pins, we can give out a multicolored display.”

Salesforce launches dev kit for wearables

Salesforce has rolled out a software development pack for wearable devices. Backed by a number of industry heavyweights such as ARM, the dev kit is expected to accelerate adoption of wearables in the enterprise.

“Wearables are the next phase of the mobile revolution,” said Salesforce exec Daniel Debow.

“With Salesforce Wear, companies can now capture the massive opportunity these devices offer to connect with customers in new ways.”

According to a recent IHS white paper titled “Wearable Technology – Market Assessment,” roughly 50 million wearable units will be sold in 2014, while more than 180 million are predicted to sell in 2018.

“With the massive number of devices coming into market, it is imperative that companies understand how consumers will operate in a hands-free world. Wearables are the future of mobile, and companies can now discover new ways to market, sell, service and more,” added Debow.

As we’ve previously discussed on Bits & Pieces, wearable device technologies will become an integral part of enterprise mobile enablement strategies – increasing at an impressive CAGR value of 56.1% over the next five years.

As senior ABI Research enterprise analyst Jason McNicol notes, the North American region is expected to be the largest, growing at a CAGR value of 39% over the next five years. Meanwhile, the Asia-Pacific region is slated to become the second largest market, outpacing Europe by 2019 with a CAGR of 90%.

“There are cases being made for wearables in the enterprise despite the relative newness of the technology. However, which wearables are primed for enterprise usage and adoption is a more important question,” McNicol explained.

“Wearable technology such as smart glasses and those used for healthcare are better suited for the enterprise as corporate-liable devices. Smartwatches, on the other hand, will most likely follow the trend of BYOD into the enterprise.”

More specifically, ABI Research recently identified six types of wearable devices: smart glasses, cameras, smart watches, healthcare, sports/activity trackers and 3D motion trackers. Healthcare wearables, smart glasses and smart watches will be the dominant form-factors purchased by the enterprise and used by employees.

All told, the research firm expects a total of 90 million wearable devices to ship in 2014 across multiple markets. As senior analyst Joshua Flood points out, wearable tech will be characterized by a diversity of products, although only those with clear use-cases and target audiences are likely to succeed.

“[2014] will be a critical period for the acceptance and adoption of wearable devices. Healthcare and sports and activity trackers are rapidly becoming mass-market products,” the analyst confirmed.

“On the flipside, wearable devices like smart watches need to overcome some critical obstacles. Aesthetic design, more compelling use cases, battery life and lower price points are the main inhibitors. How vendors approach these challenges and their respective solutions will affect the wearable market far in the future.”

According to Flood, chipset vendors are beginning to pave the way with interesting wearable reference designs that will allow non-technology OEMs and brands to quickly jump upon the wearable device bandwagon and offer diverse, innovative, unique and stylish solutions.

“While smart glasses could be the starting point moving away from today’s touchscreen smartphones to eyewear devices using a voice interface, pricing, battery life and style will all play crucial roles for market traction,” he continued.

“Due to these limitations, the enterprise sector will be the early target for smart glasses before they are ready for mass-market adoption. [We] expect more than two million smart glasses [to] ship in 2014, [with] the category forecast to grow rapidly from 2015 onwards. Mobile enabling technologies like augmented reality will play a vital part in enhancing smart glass capabilities.”

Indeed, smart glasses and smartwatches will account for a relatively small segment of the wearable device market in 2014, with medical, wellness and sports and activity wearable devices expected to provide the bulk of wearable device shipments this year.

“Activity trackers will continue to be the most popular wearable device as people carefully monitor their activity levels and energy output. Concerns around weight management and even obesity are the prime drivers behind this wearable device type,” Flood concluded.

“The collection and analysis of the captured personal performance data through associated websites and their communities is also a crucial element in building out the use-case.”

Arduino takes on Simon – and wins!

Simon is an old school electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison, with software programming by Lenny Cope.

Image Credit: Wikipedia

According to Wikipedia, the majority of the Assembly language for the game was written by Dr. Charles Kapps, who taught computer science at Temple University.

Recently, a Maker named Ben North and his 7-year-old daughter designed a Simon-playing robot that is capable of beating the classic game.

As HackADay’s Brian Benchoff reports, North uses a key chain version of the game that is much smaller and easier to work with in terms of automatically sensing lights and pushing buttons.

“The arms are made from LEGO bricks, held up with rubber bands and actuated with two servos mounted on a polycarbonate cutting board,” he explained.

“To detect Simon’s lights, Ben connected four phototransistors to an Arduino Duemilanove (Atmel ATmega328 MCU). The Arduino records the pattern of lights on the Simon and activates the Lego arms in response to that pattern.”

As North notes, the Simon-playing robot, while fully functional, does have a number of limitations.

“This is not an industrial-strength robot. It’s quite fussy about ambient light, even with the calibration. This explains the slightly grainy videos, as they had to be shot without proper lighting,” he added.

“Once or twice, the finger-pulling elastic bands slipped, meaning a finger didn’t completely press its button and the game was lost. Also, I think the robot would have been better with some flashing lights.”

We think the robot is impressive, nevertheless!

ATmega2560 powers UPS solar controller



Markus Loeffler has debuted an Atmel-based solar UPS controller.

Powered by the popular ATmega2560 microcontroller (MCU), the UPS controller comprises three primary blocks:

  • 120V AC unit
  • 12/24V DC unit
  • Microcontroller and sensors

“The controller [is tasked with] transfer switching between the solar powered inverter and main utility power to optimize battery life and maximize solar energy usage,” Loeffler explained in a recent blog post.

“It is also monitoring phase shift between utility power and inverter and only switches in phase-sync to protect your equipment. [In addition], the controller offers a standby UPS mode to provide surge protection and battery backup around the clock.”

According to Loeffler, the run-time for the battery-operated UPS mode depends on the type and size of batteries and rate of discharge, as well as the efficiency of the inverter.

“A wide variety of inverters and battery sizes can be combined. You can setup a minimal system with 12V, 10AH and go up to 24V, 500AH using common lead-acid batteries. [Plus], the controller has a simple menu driven setup mode where levels for different kinds of battery types can be adjusted,” he noted.

“If you are a hacker, Maker, inventor or DIY person, and like to build your own prototypes this is a new platform you can use to build electronics that plug into 120V and control high power items like heaters, pumps, lights, etc.”

Aside from Atmel’s ATmega2560 MCU, key UPS solar controller feature and specs include:

  • AC 2x inlet, 1x outlet 10A @ 120VAC, 60Hz
  • Solar panel terminal 50A @ 12-50V
  • Charge controller terminal 50A @ 12/24V
  • Inverter terminal 50A @ 12/24V
  • Battery capacity range 10-500AH @ 12/24V
  • Temperature range -20 … 60C
  • RGB display
  • Two menu buttons and a slide switch for the operation mode
  • 1.5A @ 5V USB connector (to charge phone, pad, etc directly)

“The controller is essentially an Automatic Transfer Switch (ATS) that switches a load between two sources. It automatically switches when it senses one of the sources has lost power. The type is called open transition transfer switch. It is a break before make transfer switch which breaks contact with one source of power before it makes contact with another,” Loeffler added.

“This prevents back-feeding from an inverter/generator back into the utility line. The ATS will automatically tell the inverter to start. Once the ATS sees that the inverter is ready to provide electric power, the ATS breaks the home’s connection to the utility grid and connects the inverter. The inverter supplies power to the electric load, but is not connected to the electric utility lines.”

Video: Atmel demos QTouch tech at Computex



Atmel’s comprehensive QTouch Library makes it simple for developers to embed capacitive-touch button, slider, and wheel functionality into a wide range of microcontroller applications.

The royalty-free QTouch Library provides several library files for each device, supporting various numbers of touch channels – enabling both flexibility and efficiency in touch applications.

Simply put, by selecting the library file supporting the exact number of channels needed, developers can achieve a more compact and efficient code using less RAM.

Earlier this week at Computex 2014, Atmel staff engineer Paul Kastnes demonstrated the integration of QTouch solutions with low-power consumption, using ARM Cortex-M0+ microcontrollers and sensor engines.

In addition, Atmel senior manager Dr. John Logan showcased how mobile applications can be customized using customized sensors, exhibited by a modified SAM D20 ARM Cortex-M0 microcontroller and an accelerometer gyroscope.

Open source IoT with Contiki

Contiki – an open source OS for the IoT – is developed by a world-wide team of devs with contributions from a number of prominent companies such as Atmel, Cisco, ETH, Redwire LLC, SAP and Thingsquare.

Image Credit: Wikipedia

Essentially, Contiki provides powerful low-power Internet communication, supporting fully standard IPv6 and IPv4, along with recent low-power wireless standards: 6lowpan, RPL and CoAP.

With Contiki’s ContikiMAC and sleepy routers, even wireless routers can be battery-operated. 

Contiki facilities intuitive, rapid development, as apps are written in standard C. Using the Cooja simulator, Contiki networks can be emulated before being burned into hardware, while Instant Contiki provides an entire development environment in a single download.

Recently, the open source Contiki was featured by Wired’s Klint Finley, who describes the versatile OS as the go-to operating system for hackers, academics and companies building network-connected devices like sensors, trackers and web-based automation systems.

“Developers love it because it’s lightweight it’s free, and it’s mature. It provides a foundation for developers and entrepreneurs eager to bring us all the internet-connected gadgets the internet of things promises, without having to develop the underlying operating system those gadgets will need,” he writes.

Image Credit: Wikipedia

“Perhaps the biggest thing Contiki has going for it is that it’s small. Really small. While Linux requires one megabyte of RAM, Contiki needs just a few kilobytes to run. Its inventor, Adam Dunkels, has managed to fit an entire operating system, including a graphical user interface, networking software, and a web browser into less than 30 kilobytes of space.”

Unsurprisingly, consumer technology companies are beginning to embrace Contiki as well. To help support the burgeoning commercial usage of Contiki, OS founder Adam Dunkels ultimately left his job at the Swedish Institute of Computer Science and founded Thingsquare, a startup focused on providing a cloud-based back-end for Contiki devices.

“The idea is to make it easy for developers to connect their hardware devices with smartphones and the web,” added Finley.

“Thingsquare manages the servers, and provides all the software necessary to manage a device over the web.”

It should be noted that Thingsquare recently showcased various Internet of Things (IoT) applications at Embedded World 2014 in Nuremberg, Germany.

Indeed, a number of Thingsquare’s demonstrations were powered by Atmel’s recently launched SAM R21 Xplained PRO evaluation board – illustrating the seamless integration of Thingsquare’s software stack with Atmel’s new SAM R21 ultra-low power wireless microcontroller (MCU).
