Every MobileNode comes with an attached tag, which contains both a public and private key. As its creators Oscar Rojas and Camilo Rojas reveal, you can push data to the cloud with the private key, while accessing such information via the public key. Meanwhile, GPS coordinates are shown in a Google Map along with the board’s orientation data given by its e-compass.

Introducing a personal assistant to help you remember your things


THE O will make sure you never leave your valuables behind again.


With people always on the go and in a rush these days, it’s easy to leave important things behind by accident. Even if you’re on alert, an item can slip out of your pocket or purse without your knowledge. But thanks to THE O, not anymore.

photo-original

Billed as “a comprehensive virtual personal assistant,” the smart accessory will notify you as soon as you forget or misplace one of your belongings. THE O can easily attach to just about anything, from your keys and wallet to your jacket and briefcase. The wearable unit comes in three different models: original and octopus (gunmetal rhodium), luxury (gold plated), and light (rubber).

The accessory works by connecting to an accompanying mobile app via Bluetooth and alerting you only when it needs to, acting as a virtual leash when you’ve moved too far away from your item. THE O can also check your essentials for you before leaving the house in the morning or after getting up from lunch, storing GPS location and time then marking needed items on appropriate days.

Buddy is the smartest dog collar ever


Buddy is a fully-integrated LED dog collar that’s connecting humans to their dogs like never before.


Currently live on Kickstarter, Buddy is a fully-integrated LED dog collar that does a whole lot more than simply light up with vibrant colors. The latest wearable for pups from Squeaker uses GPS, Bluetooth and Wi-Fi technologies to keep our four-legged friends safe while tracking and organizing their activities in real-time.

Did you know over six million dogs are injured or killed on our roads each year? Unfortunately, a large number of those incidents occur at night where visibility is hindered. We can’t always trust the judgement of others, so why take a chance with your beloved pets safety and well-being? That’s why Buddy offers owners a peace of mind by monitoring their daily activity and whereabouts in real-time via GPS, so you know where they are and what they are up to at the press of a button.

While up until now LED collars have been a one color proposition, Buddy is changing the game with a stack of individually programmable lights that allow the device to display an almost infinite amount of unique patterns and color combinations. Meaning, not only will it keep your dog illuminated and clearly visible from potential mishaps with cyclists, vehicles and other hazards, it can do so in style. These hues and sequences can be selected and managed via an accompanying app on your iPhone, Android smartphone or Apple Watch.

92dd7b81f1a8cd4e8a949620faf196db_original

In terms of hardware, Buddy is equipped with a microprocessor, a Bluetooth Low Energy module, an OLED display, a three-axis accelerometer, a temperature sensor, a light sensor that can detect the time of day, and a rechargeable battery life of 14 days. Like a Fitbit for dogs, the collar can also track steps, distances traveled and activity loads by collating data from its accelerometer and gyroscope, as well as analyze sleep patterns and vital signs.

To conserve battery power, the Squeaker team developed a Wi-Fi charging dock that communicates with the collar while handling all of the Wi-Fi power demands. Not only does the Buddy base station have its own nifty RGB lighting effects, it can visually alert you if a pet has left the geo-fenced area.

Speaking of which, Buddy enables users to set custom safe zones for their pet. This creates a virtual boundary around specific areas that you setup and control, using geofencing technology built right into the collar and app. Should good ol’ Fido venture out of these pre-defined areas, you’ll be notified instantly and prompted to their location with step-by-step instructions.

Additionally, the Buddy app has built-in barcode scanning functionality and contains an up-to-date database of the most popular pet foods by vets and other dog professionals. In other words, you can input their daily calorie intake so Buddy can offset this against their daily exercise for a clear picture of their health. This information can then be provided to your vet.

As if all that wasn’t enough, Buddy was designed with the Internet of Things in mind. And so, the intelligent collar easily integrates with your smart home devices. For instance, its embedded temperature sensor will let a Nest thermostat know if your canine companion is either too hot or cold, then adjust accordingly. The wearable can even alert you via your LIFX or Phillips Hue smart bulbs if something goes wrong.

Whew… that’s a lot. But as those with pets know, there’s no such thing as having too much safety and fun when it comes to man’s best friend. Interested? Hurry over to its Kickstarter campaign, where Squeaker is currently seeking $281,233. Units are expected to ship to backers in December 2015.

Why do drones love the Atmel SAM E70?


Eric Esteve explains why the latest Cortex-M7 MCU series will open up countless capabilities for drones other than just flying. 


By nature, avionics is a mature market requiring the use of validated system solution: safety is an absolute requirement, while innovative systems require a stringent qualification phase. That’s why the very fast adoption of drones as an alternative solution for human piloted planes is impressive. It took 10 or so years for drones to become widely developed and employed for various applications, ranging from war to entertainment, with prices spanning a hundreds of dollars to several hundreds of thousands. But, even if we consider consumer-oriented, inexpensive drones, the required processing capabilities not only call for high performance but versatile MCU as well, capable of managing its built-in gyroscope, accelerator, geomagnetic sensor, GPS, rotational station, four to six-axis control, optical flow and so on.

Drone-camera-use-cases-for-atmel-sam-e70

When I was designing for avionics, namely the electronic CFM56 motor control (this reactor being jointly developed by GE in the U.S. and Snecma in France, equipping Boeing and Airbus planes), the CPU was a multi-hundred dollar Motorola 68020, leading to a $20 per MIPS cost! While I may not know the Atmel | SMART SAM E70 price precisely — I would guess that it cost a few dollars — what I do I know is that the MCU is offering an excess of 600 DMIPS. Aside from its high performance, this series boasts a rather large on-chip memory size of up to 384KB SRAM and 2MB Flash — just one of many pivotal reasons that this MCU has been selected to support the “drone with integrated navigation control to avoid obstacle and improve stability.”

In fact, the key design requirements for this application were: +600 DMIPS, camera sensor interface, dual ADC and PWM for motor control and dual CAN, all bundled up in a small package. Looking at the block diagram below helps link the MCU features with the various application capabilities: gyroscope (SPI), accelerator (SPI x2), geomagnetic sensor (I2C x2), GPS (UART), one or two-channel rotational station (UART x2), four or six-axis control communication (CAN x2), voltage/current (ADC), analog sensor (ADC), optical flow sensor (through image sensor Interface or ISI) and pulse width modulation (PWM x8) to support the rotational station and four or six-axis speed PWM control.

For those of you who may not know, the SAM E70 is based on the ARM-Cortex M7 — a principle and multi-verse handling MCU that combines superior performance with extensive peripheral sets supporting multi-threaded processes. It’s this multi-thread support that will surely open up countless capabilities for drones other than simply flying.

Atmel | SMART ARM Cortex M7 SAM E70

Today’s drones already possess the ability to soar through the air or stay stationary, snapping pictures or capturing HD footage. That’s already very impressive to see sub-kilogram devices offering such capabilities! However, the drone market is already looking ahead, preparing for the future, with the desire to get more application stacks into the UAVs so they can take in automation, routing, cloud connectivity (when available), 4G/5G, and other wireless functionalities to enhance data pulling and posting.

For instance, imagine a small town tallying a few thousand habitants, except a couple of days or weeks per year because of a special event or holiday, a hundred thousand people come storming into the area. These folks want to feed their smartphone with multimedia or share live experiences by sending movies or photos, most of them at the same time. The 4G/5G and cloud infrastructure is not tailored for such an amount of people, so the communication system may break. Yet, this problem could be fixed by simply calling in drone backup to reinforce the communication infrastructure for that period of time.

While this may be just one example of what could be achieved with the advanced usage of drones, each of the innovative applications will be characterized by a common set of requirements: high processing performance, large SRAM and flash memory capability, and extensive peripheral sets supporting multi-threaded processes. In this case, the Cortex M7 ARM-based SAM E70 MCU is an ideal choice with processing power in excess of 640 DMIPS, large on-chip SRAM (up to 384 KB) and Flash (up to 2MB) capabilities managing all sorts of sensors, navigation, automation, servos, motor, routing, adjustments, video/audio and more.
