The Maker Movement is shaping the future

It is no secret that the Maker Movement is gaining a foothold in modern society. Writing for Newsweek, Louise Stewart highlights how the blossoming DIY culture is being adopted in schools across the nation.

In her article, Louise highlights High Tech High (you read that right!) in San Diego. The school resembles a set from a Pixar movie more than a typical, drab American high school. With spinning pulley systems turning a massive clock and a glass-covered piano front and center, it is obvious this isn’t your ordinary venue of education. Created 14 years ago, CEO and Founding Principal Larry Rosenstock describes the charter school’s core principal as “kids making, doing, building, shaping and inventing stuff” without the focus of one single subject.

Today, a growing number of schools (and other educational venues such as museums) are creating new programs and spaces to enable a greater convergence of both art and technology. Many would compare this “new industrial revolution” as the combination of the old shop class spirit with modern-day technology in do-it-yourself spaces.

With the High Tech High’s wide-open learning process, projects can revolve around history, engineering, and physics all at once; instead of segmented pieces. Stewart notes that some of the previous displays at the school have included “a World War I–era restaurant and cabaret, an art gallery, a museum-like exhibit on the history and physics of baseball, [and] simulations of faraway ecologies.” Talk about variety!

Tony Wagner, a resident at Harvard’s Innovation Lab calls High Tech High his “favorite” school and that other educational institutions with Makerspaces are the future. The Newsweek piece details how not just charter schools are seeing the benefit of the growing Maker Movement, evident by the widespread audience at Maker Faires throughout the world.

Stewart reveals how one student at St. Ann’s School in Brooklyn, New York was so inspired by an in-class 3D printing project that he was motivated to purchase his own 3D printer for use at home. Soon, he was designing and printing iPhone cases and his favorite gadgets from video games.

Even public schools are getting in on the act, as Albemarle County Public School’s Superintendent Pam Moran describes her outlook on today’s education as attempting to “make learning so powerful and memorable” and encourage students to be “constantly looking at the world in terms of problems that they can solve.”

As the global Maker Movement continues to converge education and technology, we have to note the youth aren’t the only ones taking advantage of the DIY revolution.

Writing for the Huffington PostAnna Clark details the story of Charlie Lindahl, who learned computer programming in ’68 and ’69 with a modem using an interactive terminal back when everyone was using batch processing with punched cards. “Trying to explain this to people was like being an alien.”

Charlie plans to roll out a startup MerryMaker Labs where a “No Fear Electronics” curriculum will be adopted. Charlie’s goal is to minimize any trepidation an individual would have when thinking about taking a step into the Maker world. Have no fear Makers!

Why are we teaching people to make quirky new gadgets out of old and random stuff? “Because it’s fun!” says Lindahl.

As Clark points out, DIY isn’t just for people with nothing better to do; in fact, it’s for anyone and everyone who are intentional about learning, achievement and skills mastery. From the outset of the Maker Movement, coders, knitters, mechanics, electronics tinkerers, masters of the new 3D printing process, apprentices of digital fabrication and even die-hard engineers are turning to Atmel powered devices to bring their ideas to life — maybe that’s a braille printer, a retro robot, a marshmallow canon, or even a prototype of the next big Internet of Things gadget.

When you put it like that, the popularity of the Maker Movement makes perfect sense. “See, when a system stops working — say American manufacturing — doldrums can drag on for years. As certain careers disappear and new roles emerge, folks in transition are wondering, ‘Is there something else out there that I can do?'” asks Lindahl.

Some Makers are constructing new careers as they construct new gadgets. Some Makers are skilled artisans seeking a supportive or collaborative community. Some Makers are hobbyists interested in the robotics wave. Heck, some Makers are even hip-hop artists, musicians and professional athletes. This is what makes the DIY culture so special and ubiquitous.

Bn8a1nrIYAAdhCR.jpg-large

“And some savvy startups are creating kits to simplify the process. littleBits makes prototyping with electronics simple and fun, like putting together a puzzle. Arduino is an inexpensive microcontroller that can be used for many small DIY or physical and wearable computing projects. Adafruit is a company that sells the pieces and makes the tutorials. Among other things, you can sew your own owl,” the Huffington Post article accentuates.

With more and more creative individuals being given opportunities to explore their innovative habits, the Maker Movement likely won’t be slowing down anytime soon. We can expect to see more people, ranging from hobbyists to embedded designers, turn to creating products instead of only consuming them. This is the future. And, this is fun!

Will you be joining us for World Maker Faire in New York? Don’t miss the panel discussion, “Curiosity, Imagination and Motivation: The Natural Inclinations of Young Makers,” with Atmel’s Bob Martin and Daniel Ujvari, Arduino’s Massimo Banzi, Qtechknow’s Quin Etnyre and littleBits’ Ayah Bdeir, as they explore the ways in which the STEM initiative and Maker Movement are influencing young Makers and helping to create tomorrow’s industry innovators.

World’s first LEGO band covers Depeche Mode

After The LEGO Movie demolished the box office, it was clear that our favorite childhood building blocks were ready for pop culture resurgence. With his invention, Maker Giuseppe Acito has faithfully rebuilt Depeche Mode with the tiny figures.

Covering “Everything Counts,” the Italian sound artist has revived the anthemic 1983 single and rearranged the original tune for his fully LEGO-based, ATmega328 powered band entitled “Toa Mata” (an off-shoot of the LEGO Bionicle brand). Using an automated build and a series of repurposed food packaging instruments, Acito’s band has the full capability to rock out to some ’80s classics.

“The robots are playing some unconventional drum percussions made by some food packaging are captured by a contact microphone (piezo) and processed in real time in the DAW Ableton Live,” the Maker explains. With the accompaniment of an Atmel based Arduino Uno, Acito has created a brand-new device which for the first time is “a moving platform on x-axis, made of LEGO bricks, gears and servo motors.”

What is the next step for the band? Perhaps “Tainted Love?”

As the Maker Movement continues to generate momentum, it’s always exciting to see what creative ideas DIYers will devise next — whether that’s a band comprised of LEGO or even old electronic components.

A DIY Arduino lock that can protect and track your bicycle


A smart lock to outsmart potential bike thieves! 


Those of us who live in cities know how easy it is to get around on two wheels instead of four. After all, congested traffic and packed streets make the bicycle the ideal form of urban transportation. Not only are they easy to maneuver in between cars and along sidewalks, but are a rather fun way to explore an area while staying in shape. One drawback, however, is that they are often prone to being stolen.

Maker Scott Bennett was worried about the high bike theft rate of his city, and rightfully so. Vancouver averages over 1,500 cycles stolen each year. In order to keep his means of transit safe and sound, he decided to create an Arduino-based lock system that would notify him should anything happen. With the help of an Arduino Uno (ATmega328) and an Arduino GSM shield, the small apparatus is capable of monitoring the bike at all times, while being tucked away just below his seat.

FF0TB9OHX3W4AOI.MEDIUM

When starting this project, one of Bennett’s major concerns was battery life. He didn’t want to worry about the power failing and the device itself becoming practically useless in fending off potential thieves.  And so, he employed a two-cell LiPo battery that boasted a high charge rate.

The way that the system functions is pretty straightforward: If the bike’s lock cable is cut, the Arduino starts a 15-second timer. If the lock is not reconnected within this short timeframe, the device considers the bike stolen and sends out a text message with the GPS location coordinates. Using this data, the user can then alert the authorities to the exact whereabouts of their stolen bike. It should be noted that the project does require a (prepaid) phone plan from a carrier with a GSM network.

“This project is pretty cheap, especially if you compare it to the cost of replacing your stolen bike! I was able to use some old parts I had lying around and hopefully you will too. If I had bought everything needed brand new this would have cost about $225,” the Maker writes.

Do you live in a city where bike theft is a major problem? Get started on your own lock by heading over to Bennett’s Instructables page here.

Vegard Wollan reflects on AVR and Arduino

In this segment of my chat with Vegard Wollan, the co-inventor of the AVR explores the symmetry between the highly-popular microcontroller and the Arduino development board.

Personally, one of the great moments was when Vegard revealed that the entire AVR product line was meant from the start to be easy-to-use. This began with the instruction set, the architecture and continues to this day with things like Atmel Studio 6 integrated development environment (IDE), Atmel Spaces collaborative workspace, and Atmel Gallery, the place where you can find thousands of code samples and tutorials.

Vegard-Wollen_Paul-Rako_AVR-ease-of-use

Vegard Wollan gestures to the AVR schematics as he explains to Paul Rako how ease of use was a primary design goal from the start.

So it is only natural that Arduino was built on this foundation to make their great ecosystem of development boards and their wonderful IDE. You can see Vegard truly appreciates and respects how Massimo Banzi made the entry into AVR programming even easier for both technical and non-technical folks alike.

Today, AVR 8-bit MCUs (as well as Atmel 32-bit ARM®-based MCUs) power a variety of Arduino’s easy-to-use boards including:

  • Arduino Uno: The most “standard” board currently available, the Uno is based on the ATmega328
  • Arduino Yún: The Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the Atheros AR9331.
  • Arduino Nano: The Nano is a small, complete, and breadboard-friendly board based on the ATmega328.
  • Arduino Mega 2560: The version of the Mega released with the Uno, this version features the ATmega2560, which has twice the memory, and uses the ATmega 8U2 for USB-to-serial communication.
  • Arduino Leonardo: Based on the ATmega32u4, the Leonardo is a low-cost Arduino board, featuring the same shape and connectors as the Uno board but with a simpler circuit.
  • Arduino Micro: The Micro is based on the ATmega32u4, developed in conjunction with Adafruit.
  • Arduino Esplora: Derived from the Arduino Leonardo, the Esplora is a ready-to-use, easy-to-hold controller based on the ATmega32u4.
  • Arduino LilyPad: Powered by an ATmega32u4, the LilyPad is designed for wearables and e-textiles, allowing for the board to be sewn into fabric and similarly mounted power supplies, sensors and actuators with conductive thread.
  • Arduino Due: Based on an Atmel ARM Cortex®-M3 processor-based MCU — also known as the SAM3 MCU — the Due board is ideal for home automation projects and can run up to 96MHz.
  • Arduino Wi-Fi Shield: Built for Wi-Fi applications, the Arduino Wi-Fi shield is powered by the Atmel AVR UC3 MCU and an H&D wireless module, and provides developers a powerful Wi-Fi interface.
  • Arduino Zero: The board is powered by an Atmel SAM D21 MCU, which features a 32-bit ARM Cortex® M0+ core.

Arduino-powered wheelchair hopes to offer greater mobility

A Maker by the name Philip Case, also known as “Cap,” has set his sights on a project that will make his and a number of others’ lives easier. Philip, who is wheelchair dependent due to an unfortunate accident, is working to further develop his incredibly innovative e-Wheelchair.

Bl7xtUFIQAEitlU.jpg-large

Similar to other mind-controlled projects we’ve recently covered on Bits & Piecesthe e-Wheelchair enables chair movement to be controlled solely by a user’s brainwaves. While some wheelchairs exist with this technology, they are very expensive. In true Maker fashion, Cap is seeking to create an Atmel based chair that is both affordable and easy to use for all who would require its services.

Cap’s system features an Arduino Uno R3 (ATmega328), an Arduino Yun (ATmega32u4) as well as a series of breakout boards. The Arduino boards interpret the brainwaves into directional movements for the chair.

For the control system, Cap has implemented the Neurosky Mindwave Mobile and a Mindflex EEG. According to the team at Cooking Hacks, Cap has been able to control forward and reverse on his chair with these tools. Though, in a recent update, steering has been changed to blink detection rather than laser, using Ultrasound for a safety stop in forward and reverse.

BlW_tp7CEAEwrun.jpg-large

Cap also wants to fully utilize the power of the Atmel powered Arduinos, so he is currently looking to install devices that can monitor glucose levels and ECG. This will likely be based around e-Health’s Sensor Platform. In addition, the future build may also incorporate a GSM/GPRS module along with an embedded body position sensor. With his aspirations to provide independence to users, he is exploring the idea of connecting a mobile device to the e-Wheelchair using both Bluetooth and USB.

To stay up to date on Cap’s build, you can follow along on his Cooking Hacks blog.

A DIY navigation device for the visually impaired

With the power of the revolutionary 1Sheeld in hand, Maker Amr Wasfy decided to put this technology to good use by developing a navigation device for the visually impaired.

FN9UVY2HYPNUSY8.MEDIUM

Integreight’s 1Sheeld – powered by an ATmega162 MCU – is an easily configurable shield for Arduino boards.

As its Kickstarter page noted, the sky really is the limit when it comes to the shield’s possibilities. Wasfy has partnered the 1Sheeld with an Arduino Uno (ATmega328) and a pair of ultrasonic sensors. He mounted the sensors to a belt and then created an enclosure for both the Arduino and the 1Sheeld.

FJZD7P9HZB3IB46.MEDIUM

In practice, the two sensors alert the user when the distance in front of them is less than 30 centimeters. When the distance is less than the desired range, the device notifies the user to rotate until the path in front of them is clear for greater than 30 centimeters.

Wasfy used two sensors, which the Maker notes was for better quality and wide range coverage. “There is a function that compares between the two readings of the sensors and takes the decision based on that.”

For a detailed step-by-step breakdown of the Maker’s build, head to his Instructables tutorial here.

The fantastic MegaCube hits Kickstarter

The Maker community has grown up, and respectively, requires a development platform to match. As many of you may already know, the Arduino has been the development platform of choice for many Makers throughout the world. The brains and heavy-lifting behind it is an Atmel AVR microprocessor. As a result, MEGADOM Electronics Inc. and DomCo Electronics, Inc. have teamed up and brought you just that: The grown-up Arduino, the MegaCube.

photo-main

At a first glance, the MegaCube looks a lot like a desktop PC processor; in fact, it is an ATmega2560 with all ancillary components onboard including a 5V LDO. At 1.8” x 2.1” in size, it’s the smallest Arduino-compatible development board, with an ATmega2560. Looking to get it going? All you need is a USB to serial TTL bridge such as an FTDI cable or In Circuit Serial Programmer (ICSP), such as the Atmel AVRISP mkII.

What sets the MegaCube apart from the original Arduino Mega and its clones is not only it’s minute size, but also that each of the one hundred pins of the 2560 are broken out for use. This includes the clock pins and additional general purpose I/O pins. It also works as a great stepping-stone for developers wanting to take the leap from Arduino to Atmel Studio. The MegaCube can act as either an Arduino or a full-featured Atmel development kit.

As opposed to the traditional Arduino platform which uses an asymmetrical pin lay-out, the MegaCube has a symmetrical layout. All pins are on a 0.1” grid and can be easily used with proto or vector board. This 0.1” grid also serves the dual purpose of making this dev kit socketable and thus embeddable permanently or temporarily.

Too many times, I have whipped up a quick proof of concept, which I would have liked to have kept intact without permanently tying up my Arduino; something in which MEGADOM Electronics has thought of as well. They created a “shield” system not all that dissimilar to the Arduino platform. They have two of them out now, with more in the works — one is the eBOSS (Embedded Break-Out Shield System) and the other is the BOSS (Break-Out Shield System). The eBOSS is at the core of this concept. You can easily solder the eBOSS into your proof of concept and then just socket the MegaCube into it.  This way, when you need your MegaCube for a different project, you don’t have to destroy your current project to use it. Rather, you can simply unplug the MegaCube board from the eBOSS and plug it into another eBOSS attached to a different project. I can envision the eBOSS also being used in finished products, where the product comes with an eBOSS and is offered as a complete solution with a MegaCube or without one offered at a lower price point, with the purchaser using his or her own MegaCube.

MEGADOM’s chief engineer, Mike Dombrowski, also has a demo in the works for putting multiple programs on the MegaCube. For instance, if you are using the ATmega328-based Arduino Uno platform, you could put up to eight full Uno programs on the MegaCube. By using a unique ID chip attached to each eBOSS, the MegaCube would be able to determine which program to run, making it a snap to switch between projects. Dombrowski’s demo switches between a robotic arm and a Bluetooth Remote controlled tank without reprogramming the firmware.The robotic arm using the eBoss and the MegaCube is on MEGADOM’s Kickstarter project video. Rumor has it MEGADOM is going to be selling the robotic arm as a kit as well!

The eBOSS

The other shield system MEGADOM created is the BOSS. The BOSS was created to allow those new to Arduino to use a MegaCube as if it were an original Arduino Mega, because the BOSS is the same size and footprint as the original Arduino Mega (ATmega1280, an AVR based high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 128KB ISP flash memory, 8KB SRAM, 4KB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers) and gives you access to only the same pins as the Mega. The creator tells me the BOSS will have an R3 footprint in final release versions. This allows the MegaCube to dock with the BOSS giving you the standard Arduino footprint and use standard Arduino shields with the MegaCube. Once again, it’s a great launching platform for engineer or Makers that want to prototype and prove in their design before embedding it into a project full-time or in a more pertinent fashion.

The eBOSS, with a MegaCube takin' a ride

The MegaCube and its shields were created to bring the Atmel ATmega 2560 [Atmel AVR based Microcontrollers] to the forefront of the budding Maker Movement. It unleashes more flexibility in a platform that is smaller and can be socketed and embedded into projects. As you can see, the MegaCube has a promising future with the Arduino Community and it’s already spawning similar designs on the Arduino Forums. To find out more about the MegaCube go to the MegaCube’s Kickstarter campaign or the MEGADOM homepage.

Connecting multiple boards together with ChainDuino

After a highly successful Kickstarter campaign, the ChainDuino project has entered its final stretch of crowdfunding.

Arduino-Board1

Michael Tedeschi originally created the ChainDuino after realizing that he wished it were simpler to connect multiple Arduino Uno (ATmega328p) boards with readily available Cat5 cable. To get the ChainDuino idea off the ground, he set a crowdfunding goal of $2,500, which has well exceeded by raising over $8,800 to date.

According to its site, the ChainDuino is a daisy-chainable, Arduino-compatible development board that enables Makers to easily connect multiple boards together with standard Cat5 cable. The boards communicate using built-in RS-485 circuitry, and share power using passive PoE+ over the same Cat5 cable. Tedeschi’s design operates on an open source platform and allow news boards to be added to the chain simply by programming them with the Arduino IDE and plugging them in.

877041e6400bef8afb97debe8ca20f62_large

Tedeschi was fascinated with the idea of using an Atmel-based Arduino to monitor data from multiple locations simultaneously. “I needed a simple way to connect microcontrollers together to focus on the functions of each node, instead of wasting time solving how to connect the nodes to each other.”

Some have questioned why Tedeschi did not adopt wireless technology for the ChainDuino project, but he explains, “While I do find wireless gadgets fascinating, I have always been more of a hardwired fan when it comes to permanent installations.” He reveals he is also a proponent of powering remote devices over Cat5, also known as Power over Ethernet, or PoE.

afe482b0627509e5522cf028a47fcf55_large

Tedeschi has found that up to 25 boards can be linked using his system and has successfully tested the unit at a mammoth length of over 1,600 feet!

Upon reaching his funding goal, the Maker will first and foremost be using the money to fill Kickstarter backer’s orders of the ChainDuino. He will then look to begin developing an enclosure and further prototypes. He also has thoughts of adapting his design to work with either an Arduino Mega (ATmega1280) or an Arduino Pro Mini (ATmega168).

The board layout is loosely based on the Arduino Uno (without the USB):

  • Microcontroller: ATmega328P
  • Operating voltage: 5v
  • Input voltage: 7-28v DC
  • Digital I/O:14 pins (6 pwm)
  • Analog Inputs: 6
  • DC each I/O: 40ma
  • DC for 3.3v: 150ma
  • DC 5v onboard: 500ma
  • Clock speed: 16 MHz

Additional features include:

  • RS-485 half-duplex MAX485 chip onboard (pins 0,1,2)
  • RS-485 terminating & bias resistors selectable with dip switches
  • 28v DC switching regulator supplies 5V up to 500ma
  • VIN pin on Arduino header disconnected by default to protect some shields from > 12v (enable with simple solder joint)
  • PoE+ support for 24v DC power over Cat5
    passive PoE pins (+) 4,5 and (-) 7,8
  • I2C pullups onboard, disabled by default (enable with solder joints)
  • FTDI headers onboard
  • ICSP header onboard
  • Daisy-chainable via RJ45 ports or IDC connectors
    (insulation displacement of 24-26 awg wire)
  • WS2812b RGB LED onboard (pin 13)

Turning old floppy drives into music

Remember that irritating etching noise that aging floppies emitted when they would boot up? Maker Chris Fry has harnessed the sonic power of these old drives and turned them into some musical masterpieces.

FK6N132HZ6T6X91.MEDIUM

We have featured Chris Fry’s ATmega328-based work previously on Bits & Pieces, as his life-like recreation of the Flux Capacitor from “Back to the Future” was a huge hit. Now, instead of remaking a classic movie prop, Fry has programmed a series of floppy drives to play the theme songs to some of his favorite Hollywood hits.

Fry blew the dust off of eight floppy drives that he collected and began researching on Instructables how to repurpose them into a programmable musical machine. With the power of an Arduino Uno (ATmega328) and a hefty ATX power supply, the Maker had his drives linked up and ready to jam.

“Some floppy drives are louder than others, so it might pay to try a couple out first before buying loads of them.” Fry noted. He went on to recommended that all of the drives have similar sound quality as “it would be no good if one drive is really loud and the others are quieter as the loud one would drown out the sound of the others.”

Once his contraption was wired up, he proceeded to install the Moppy software program, which allows the drives to play MIDI sound files. From there, he was ready to put on a full on nostalgia filled concert!

Here are some of our favorite tracks that the creative Maker programmed his ATmega328-powered floppy drive boom box to play…

ATmega328 helps make the Ice Bucket Challenge accessible to all

If you’ve logged into any of your many social media accounts over the last few weeks, you have undoubtedly seen the ALS Ice Bucket Challenge. Though there are varied opinions on the latest viral phenomenon, a Maker by the name Christopher Lewis has taken the cause to heart when accepting his challenge.

20140824_131835-1024x768

In true Maker fashion, Christopher used his ingenuity to make his Ice Bucket Challenge video stand out from the norm. He wanted to highlight the utility of Augmentative/ Alternative Communication (AAC) devices used by individuals with neurodegenerative diseases like ALS or Parkinson’s.

Using a barometric switch, which is commonly found of AAC devices, and an Arduino Uno (ATmega328), Christopher developed a hands-free Ice Bucket Challenge Backpack. The wearer simply blows into a tube to activate a sensor, which then sends a signal to the Arduino, and starts the soaking process.

Arduino-uno

Christopher used this method to participate in the Ice Bucket Challenge in order to raise awareness for what the Maker community could do to improve the lives of those impacted by these diseases. While a vast majority of AAC equipment are quite expensive, as seen with several DIY medical devices, Makers could ultimately create similar tools for much, much less.

The Ice Bucket Challenge has already raised nearly $80 million over the last month and donations are still rolling in at a record pace. Hopefully this social media movement, along with inventiveness from Makers like Christopher, can help fight this disease in the future.

You can view Christopher’s entire tutorial on his blog. To learn more about the ALS Ice Bucket Challenge, feel free to browse the ALS Association’s homepage.
