Send your hearts fluttering with an ARM-powered wireless platform

taylor-alexandor-Flutter-WirelessA talented Maker by the name of Taylor Alexander, co-founder of Flutter Wireless, has recently gained a large amount of support for the company’s innovative wireless electronics development platform based on Arduino.

No novice to DIY, Taylor has spent a life of hacking, making and transfiguring things to have them do all sorts of different actions than these electronics were originally made to do. At the early age of five, he would break things down and rebuild them to create something entirely different — taking parts from old cameras, stereos and other electronic components, then transforming them into electric cars. From early on, it was evident Taylor was an innovator in the ‘making.’ Now, as everyone has witnessed, there are crowdfunding platforms such as Kickstarter, a startup incubator platform where individuals like Taylor and his co-founders can create value from their extraordinary talents and early fundamental interest.

Not only has Kickstarter offered a new way of doing things, but the platform is reshaping the business and creation cycle for people with talents in technical and creativity. The site has enabled people to get financing, allowing inventors to obtain the investment needed much faster at the early stage of incubation and product development. This money can then be better used to scale faster and prove its concepts early on via social acceptance and crowdfunding with the merits of community and validation.

The powers of the Maker Movement — a fabulous combination of getting the media, bloggers and influencers onboard, riding pre-existing trends, thinking outside the box, conducting frequent demonstrations, all while responding to the ideas and wants of the community. Arguably the most important aspect of the DIY revolution is the validation and acceptance of the community wanting to endorse and witness an idea come to fruition. At an individual level, it’s an exciting and opportunistic time for an inventor or anyone looking to contribute to the landscape of technology or where it is going. These are some of the most compelling reasons as to why Flutter Wireless is able to prove innovative ground, validate their product ideas and infuse the necessary capital to promote more success across communities. As in its Kickstarter’s illustration, the wireless electronics development platform can be communicated from of a large 3,200 ft (1km) usable range. It is packaged with a powerful Atmel ARM-based SAM3S processor, coupled with integrated encryption using Atmel’s ATSHA204 cryptographic chip as the device to secure it’s system.

So, how does this wireless platform work? Well, as the Flutter Wireless site explains:

“Creating Flutter networks are easy, even if it’s just two boards. Specify networks in Arduino code or configure Flutter with our mobile app. Once configured, devices can enter and exit the network seamlessly. This makes it extremely easy to set up a network at home (or anywhere else) where all of your projects can reliably communicate. Flutter is like a second network for your devices.”

In fact, in the landscape of connecting devices and IoT, an individual building out of a wireless project shouldn’t have to be too expensive. “Flutter was built from the ground up with cost in mind, that’s why our boards start at just $20. We’ve worked hard to keep costs as low as possible and deliver you a quality product you can afford to use in as many projects as you’d like,” explains Taylor. flutter-basic-and-flutter-pro-with-atmel-arm-cryptography The startup extraordinaire Taylor has helped further the ecosystem development by leveraging the concepts of “shields” and designing a handful of various protocol shields for Flutter. It’s really focused on individuals who want to get started quickly and build heterogeneous nodes of connected devices on a network. The Flutter boards come shipped with breakout boards and socket headers, combined with the power of connectivity to various protocols (Bluetooth 4.0 Low Energy or conventional Bluetooth 2.1). The Flutter Wireless platform is comprised of the network shield which connects to your home router, creating a bridge between mobile devices (M2M) the Internet and Flutter. For a wireless system, the important factors are range and reliability. According to Flutter Wireless Kickstarter:

We use WiFi everyday, but take a few steps down the driveway and coverage quickly becomes scarce. Flutter is a different kind of wireless system, completely self-contained with over a half-mile range. This allows for a wireless platform without borders, and no longer being chained to a router means your projects are free to follow you out the front door, through the yard, and down the street.”


As previously discussed in Bits & Pieces, the combined Flutter Wireless Development platform is quite comprehensive, considering it’s Kickstarter and crowdfunding origins. Flutter Wireless comes packaged with Atmel’s ATSHA204 to ensure maximum secure storage and protection of encryption keys. Flutter is designed to address security and wireless in a combined package. The platform is comprised of a design, which encompasses a special cryptographic hardware (Atmel’s ATSHA204) that integrates cryptography into every communication layer of the software. In essence, this gives the user ultimate control over who can and cannot communicate with their devices.

The project is given strengths by making it accessible via the Open Source community – ensuring the possibility of enhancing the roadmap by contribution to improve upon Flutter Wireless foundation though the power of the community. Furthermore, Flutter’s wireless concept seamlessly routes messages across a varied number of connected devices to reach their destination. It’s sort of like a lily pad of daisy chaining across many nodes or protocols. With that said, there is a world of potential in the IoT buildup for a number of reasons. Arduino already has a big open-source following. First, this is already proven (via the Maker Movement and Maker Faire) and it’s one of the easiest ways to bridge the physical and digital worlds together. Flutter Wireless can be a node in a larger mesh network, which could be useful for large public projects. (i.e.  Let’s say, a hobbyist or passionate drone user wants to fly his drone to the next town over, keep it connected across RC and mesh networks all within good range and security).

The winning formula:

ARM + Encryption + Easy Development + New IoT-Based Radio + Mesh + Shields + Open Source + Community + Crowdfunding = Thousands of lines of agile code, mesh support, tagging, and various protocol features required to support IoT buildup

Potential applications for Flutter Wireless include:

  • Quadcopters
  • Landscape sensors
  • Agriculture remote sensor installations
  • Remote security implementations
  • Crowdsourcing spectrum analyzers
  • RC hobbyists

Flutter still finds itself under development and continually evolving. The prototypes were designed with the Sparkfun Arduino Pro Mini for rapid development and proof of concept. Out of this ideated adventure, a new generation of boards are in the process being developed with Atmel SMART™ ARM-based SAM3S, a very affordable, versatile and powerful ARM core processor with a capacity for speed and storage space to suit any designer’s connected device project.

More details can be found via the Flutter Wireless website. Devices found within this innovative wireless development platform can be found at Atmel’s product ARM processors page and said security components can be located on Atmel’s Cryptography product page.


Building a $20 wireless platform with the Atmel-powered Flutter

Flutter – which recently tipped up on Kickstarter – can best be described as an open source Atmel-powered wireless platform with a 1000m+ (3200 ft) range. Protected from digital intruders by Atmel’s ATSHA204 which offers 256-bit AES hardware encryption, Flutter makes it easy for DIY Makers to build projects that communicate across a house, neighborhood and beyond.

“Creating Flutter networks is easy, even if it’s just two boards. Specify networks in Arduino code or configure Flutter with our mobile app,” the Flutter crew explained in a Kickstarter post. “Once configured, devices can enter and exit the network seamlessly. This makes it extremely easy to set up a network at home (or anywhere else) where all of your projects can reliably communicate. Flutter is like a second network for your devices.”

In terms of hardware, the Flutter crew is currently offering a range of options for Kickstarter backers, including basic, pro and a number of shields (Bluetooth, breakout board, RC, network and Bluetooth).

Potential applications for Flutter? Mesh networking, quadcopters, sensors (light, water and temperature) sensors, self-diagnosis/spectrum analyzer, as well as RC cars.

As noted above, Flutter is powered by Atmel technology. More specifically, prototype devices were originally designed using the  Arduino Pro Mini board (Sparkfun), although the final version of Flutter will be built around Atmel’s SAM3S, based on a powerful ARM CPU with plenty of speed and storage space.

Death of the DSP

OK, so that title is intentionally provocative. The DSP is not dead yet. But as I learn about Atmel’s ARM processors, I ask myself why I would ever use a DSP chip. The Atmel Cortex M4 has single-cycle multiply accumulate. It’s got floating-point math. Its pin-to-pin compatibility with Atmel SAM7S, SAM3N and SAM3S microcontrollers. The CPU has DSP extensions. And Atmel parts sip power compared to traditional DSPs. One of the coolest features in parts like the SAM4L is how you can set up the peripherals to operate and even write to memory without waking up the core CPU. So all these features plus the appeal of ARM compatibility is putting a lot of pressure on those older DSP chips. When you look at the power of the AVR and ARM chips Atmel makes, most all of them have the power of the old DSP chips, and they get the job done using less current.
