Shows American Pride at the
Maker Faire At the heart of the maker movement, Atmel joins gathering of innovators from across the country.
By Alex Maddalena, Contributing Writer
“Today’s DIY is tomorrow’s ‘Made in America,’” President Obama proclaimed in his opening remarks at the White House Maker Faire in June of 2014. With the rise of open-source hardware like the Arduino Uno, the limits of innovation, manufacturing, and technology have become boundless. To commemorate the rise in DIY innovation, the White House sponsored its first-ever Maker Faire in Washington DC and invited makers of all ages from around the country to show off their innovations. Projects ranged from robotic giraffes to a mobile 3D printing fab lab—all of them demonstrated for President Barack Obama himself.
Arduino boards for makers
hese makers, as well as makers across the globe, have embraced the easy-to-use hardware and software of the Arduino platform, based on Atmel 8-bit (AVR) or a 32-bit (ARMbased) microcontrollers (MCU). Cited for their ease-of-use, low-power, and high-performance capabilities, the Atmel AVR MCUs have enabled designers, inventors, and even school children to learn and innovate at a previously unheard of level. Atmel’s connection with the Arduino boards earned them an invitation to this year’s Maker Faire to see the variety of projects their MCUs have powered. EEWeb spoke with Sander Arts, vice president of marketing at Atmel, about his experience at the White House and how being involved in the maker community will enable the next generation of entrepreneurs.
CROWD-FUNDED, PRESIDENT-APPROVED “When Atmel was invited to the White House Maker Faire, we were obviously excited,” Arts said, then added, “Atmel has always celebrated the makers, so to be acknowledged as being at the heart of the maker movement has been big for us.” The focus on the maker movement began when Atmel saw a surge of new projects online, ranging from hobbyists engineers to large tech companies who developed innovative technology using the inexpensive Arduino platform.
“Atmel has always celebrated the makers, so to be acknowledged as being at the heart of the maker movement has been big for us.”
With the rise of Kickstarter campaigns and other crowd-funded tech projects, Atmel embraced the ever-growing DIY community as the new frontier for tech innovation. Part of that community and invited to the White House Maker Faire were Quin Etnyre and Sylvia Todd (aka Super Awesome Sylvia). These two 12-year olds (yes, 12) have both made a mark on the maker community and came to the White House under the Atmel flag. Etnyre is the founder and CEO of Qtechknow, a company devoted to supplying Adruino-related kits for tinkering and learning, while Super Awesome Sylvia hosts her own YouTube show dedicated to DIY tech projects. “30 years ago, you had to be an electrical engineer in order to do something with hardware,” Arts remarked. “Nowadays, we have 12-year-old entrepreneurs developing projects with Arduino boards and presenting them at the White House.”
Arduino starter kit
While these projects stood out for their innovative merits alone, many were celebrated for linking their projects to the job market. President Obama noted the projects that took advantage of 3D printing and commented that the success of such products would help return manufacturing to U.S. shores. However humble the roots of these projects, whether garage or classroom made, they held the potential to have a positive impact on the U.S. economy not unlike that of the first Apple computer Steve Wozniak built in his garage.
â€œCited for their ease-of-use, low-power, and high-performance capabilities, the AVR MCUs have enabled designers, inventors, and even school children to learn and innovate at a level that has never before been seen.â€?
NEW FRONTIERS In today’s ever-changing tech industry, it’s not uncommon to find a new connected device whose developers are unsure of the product’s use. The most popular example of this is the rise of the Internet of Things (IoT). While there are a plethora of interconnected devices on the market today, tech companies and analysts still struggle to envision exactly how the IoT will take shape. “About 50 percent of the companies that are going to be a part of the IoT are companies that don’t exist today,” Arts explained. Conceivably, someone in a garage developing a smart weather meter with an Arduino and sensors may be the next big thing in the tech industry. Arts also noted that there have been 160 companies
started on Arduinos that were launched on Kickstarter, and 103 of them were successfully funded. “103 companies started on Atmel chips and that’s a significant number for us,” Arts concluded, “which is why we chose to take an active part in the maker community.” For Atmel, the White House Maker Faire is just the beginning. The company’s next step is to continue to build an audience through social media platforms. In fact, Atmel boasts one of the largest social media footprints of any semiconductor company. As a result, Atmel is poised to engage with makers who promise to be the future of emerging tech markets.
“103 companies started on Atmel chips, and that’s a significant number.”

The New Age of Single-Board Computers
f you have been interested in programming, electronics, or computing in general in the past several years, then you probably have used the Raspberry Pi. It is a wonderful, little piece of hardware that can help you learn how to code. At least, that was the intended use of the Raspberry Pi. With advanced knowledge about electronics and coding, the Raspberry Pi can be turned into more than a coding tutorial. This powerful piece of hardware can be converted into a weather station, a retrogaming device or a touchscreen tablet. The Pi does this by boasting a 700 MHz processor, 512MB SDRAM, and a dual-core multimedia co-processor. These components allow the Raspberry Pi to be a great embedded single-board computer. But, what if a project required more processing power and more data storage? A BeagleBone Black could be used, or the Raspberry Pi could be upgraded.
“Having a dual-core processor gives the Banana Pi twice the processing power of the original Raspberry Pi.”
t takes a lot of experience to design a circuit board. It takes even more knowledge to be able spin the board, meaning to design and produce a physical copy of a circuit board. So, performing electronic surgery on the Raspberry Pi to upgrade the components is not recommended. Lemaker has taken the difficulty of upgrading the circuit board to create what is called the Banana Pi. The Banana Pi has very similar architecture to the Raspberry Pi except that it is fitted with an AllWinner A20 SoC, which runs at 1GHz and 1GB DDR3 SDRAM. The AllWinner processor is actually an A20 ARM® Cortex™-A7 dual core.
So what makes the AllWinner A20 SoC so special? It’s the first dual-core ARM A7 chip. As is the case with modern computer processors, multiple cores help with multitasking. Multiple applications can send and receive data at once, giving the user more power over the tasks a user is planning to accomplish with a project. The ARM A7 processor supports integer division through it’s own hardware instruction. In other ARM based processors, integer division is calculated through software. With the integer division in hardware, this frees up memory space from software instructions allowing the processor to function more effectively. The ARM A7 processor Having a dual-core also has 40-bit memory processor gives the Banana addressing. This allows Pi twice the processing power the processor more C o S of the original Raspberry bandwidth to access the er A20 lWinn l A Pi. The dual core gives the computer primary storage. operating system the illusion This increase in bit addressing allows the that the computer has two 1GHz processor to complete more tasks in a processors.

With this technology, a graphical user interface (GUI) will load very quickly, graphical engines will process more efficiently, and movies or images will load with a higher definition. This GPU was built for the accelerated creation of objects on a screen. With this design, the user is able to run an operating system such as Android or Ubuntu without any of the hiccups that may come with a slower GPU. Now, what can you do with a little bit more processing power, more RAM, and more storage space? Actually,
quite a bit. What use to be a weather station, a retrogaming device, and a touchscreen tablet can become a fullfledge multimedia PC, a general purpose computer, or a modern gaming device. The specs of the Raspberry Pi are no longer limiting. The Banana Pi comes with all of the standard peripherals that a Raspberry Pi has, such as HDMI out, 10/100/1000 Ethernet out, audio out, and GPIO headers. With such a board, you can turn your home into the Internet of things. By adding sensors in various rooms, and a Banana Pi interfaced to the sensors, you can create a life that is connected to the Internet. This will help you remember your habits, assist with daily functions,

With the addition of a touchscreen, or even a regular monitor, the Banana Pi can fly through operating systems such as Android 4.4 KitKat, Ubuntu 13.01 or even a multimedia OS such as XBMC. But, many of the Banana Pi’s features are comparable to other cutting edge singleboard computers.

With all of the single-board computers coming out at Maker’s Fair, at Consumer Electronics Show, and across the Internet, it is hard to find one that will be perfect for any project. The Banana Pi builds on the famous Raspberry Pi, to create a fast, yet inexpensive solution for many electronic projects that need intensive computing. This is all possible because the Banana Pi is an open source. Being one of the first boards to use a dual-core processor, the Banana Pi leads the way into the development of faster and more inexpensive single-board computers. Dual core makes it possible to accomplish many more tasks that the Raspberry Pi cannot. The next generation of singleboard computers is here, and the Banana Pi is leading the way.

By Suzanne Touchette Kelso Contributing Writer
he time-honored craft of home brewing only gets better with the introduction of electronics. Find out how a DIYer improved his beer by using the popular Arduino module.
ork remotely, turn lights on remotely, and now, brew beer remotely thanks to the Arduino module. Using this microcontroller module along with a variety of electronics components, home brewer Michael ImObersteg put together a brew system that allows him to monitor his tanks from miles away. ImObersteg, who started making beer in college, developed a sophisticated electronics brewing system that is hassle free. “Brewing can be very hands-on, messy, and time consuming,” he notes, “so I wanted to streamline the process.” ImObersteg started his new brew system with the Arduino-based BrewTroller, which controls everything from volumes to temperatures, to analog or digital inputs, to valves and more. “I also used a Raspberry Pi,” tells ImObersteg, “and this powers a touchscreen monitor which is connected to the Internet.” In this way, he can remotely access the web-based GUI on the BrewTroller to control the brewery. “No matter where I am in the world,” remarks ImObersteg, “I can check in on the brewing process and control what’s going on with the batch at hand.” Because most of the brewing is done outside, conditions can suddenly change. “A flame on the burner can go out,”
ImObersteg explains, “or the temperature can shift. I can access all this information and make adjustments through my phone.” Not only do ImObersteg’s brew-system electronics allow for remote access when conditions change, but because it’s paired with an E-Stop module which reads the Arduino board, the system will drop into standby mode and come to a complete stop if something goes awry. At that point all valves close, all pumps stop, and all burners turn off. Honeywell intermittent pilots receive feedback from the system and burner, so if the burner isn’t lighting, the operation shuts down. Freescale pressure sensors attached to a pump measure the pressure in each tank. This information is used to determine the number of gallons per tank. “I’m always testing, checking, and measuring throughout the process,” says ImObersteg, “because consistency is important in order to get the finishedproduct volume the same for each batch.” While some might want a total brew experience of being elbow-deep in hops and barley, ImObersteg is content with letting his electronics system handle the tedious part of brewing. This leaves him more time for the enjoyable part of crafting beer—the tasting.
“I can check on the brewing process from anywhere in the world and control what’s going on with the batch at hand.”
Tech Tools Check out the various tech devices in Michael ImObersteg’s brewing system: Arduino Microcontroller Custom module running BrewTroller firmware. • DE v1.0.5-r2 supports ATMEGA 1284P • Atmel 8-bit AVR RISC-based microcontroller • 128KB flash, 4KB EEPROM, 16KB SRAM
Raspberry Pi Model B used as touchscreen interface for Internet connection and for GUI. • Ethernet port in conjunction with NETGEAR adapter • 2 USB ports, HDMI
Freescale Pressure Sensor Used to detect amount of liquid in tanks. • MPX5010DP with 1.45PSI pressure range • Integrated silicon sensor • On-chip signal conditioning
Capacitive Touchscreen Displays data and connects to Internet. • 10” screen with LCD IPS technology • HDMI-LVD board powering Raspberry Pi • Ambient light sensor for LCD control
Keg Content Home brewers may want to know how much beer is in their tanks as part of the brewing process, but barkeepers have a different motivation for keeping tabs on quantity. They want to ensure an adequate supply of popular drafts and avoid having kegs of expired beer. Bartenders often use a simple method to determine volume; they just shake a keg. For those who don’t want to do the shake, craft-brew aficionados and software guys Steve Hershberger and Steve Kremer teamed up to develop an online system for calculating beer volume in kegs. The two called their beer brain, “iKeg.” This inventory management system tracks information such as how much beer remains in a keg, when the keg will empty, when another delivery is planned, and so on. The iKeg system relies on a sensor, which includes a Freescale MC13224V microcontroller in the bottom of the keg. A RFID tag on the keg handle uses a 13.56MHz inlay to obtain data from the sensor. Then the data is transmitted using ZigBee.
