Renesas DevCon Extension Organizes Free One-Day Courses About IoT, Low Power, Sensors and More

I’ve just come across a YouTube video called Ultra-Low-Power Solutions for Wearable Technology and the ‘Internet of Things’ On Renesas channel. The video itself promotes Cymbet EnerChip Solid State Batteries and Kits, working together with Renesas MCUs, and the interesting part is that they’ll provide a free training session for the kit as part of Renesas Devcon Extension 2014. This is not a single event as you may think, but instead the company hosts one-day workshops in various cities in the US and Brazil covering various tracks all year long, as you can see in the simplified schedule below. RTOS & Middleware track is not available anymore, but you can still attend training sessions for Human Machine Interfaces, Low Power designs, the Internet of Things and Sensors. As an example, the following lectures are available for the Low Power track: Renesas Low-Power MCU Lineup (30 minutes) – Updated technology roadmap […]

Google Unveils Project Tango Tablet Development Kit Powered by Nvidia Tegra K1 SoC

Earlier this year, Google ATAP (Advanced Technology and Products) showcased project tango phone prototype, capable of generating 3D maps in real-time thanks to cameras, motion sensors, and two Movidius Myriad 1 Mobile Vision processors paired with a Qualcomm Snapdragon 800 application processor, and since March, they’ve already sent a few hundred samples to developers. Google has now announced another development kit, this time a tablet powered by Nvidia Tegra K1 quad core SoC. Tango tablet has the following hardware specifications: SoC – Nvidia Tegra K1 quad core Cortex A15 with Kepler GPU System Memory – 4GB RAM Storage – 128GB Display – 7″ screen Connectivity – WiFi, BlueTooth Low Energy, and 4G LTE Camera – 120 deg. wide angle front camera, 4MP rear camera, and motion tracking camera Sensors – Integrated depth sensing The tablet will run Google’s KitKat Android operating system, and support features such as OpenGL 4.4 thanks to the […]

$120 Raspberry Pi Bundle with LCD Display, Expansion Boards, Cables, and Accessories

Yesterday, Element14 has announced Wolfson Audio Card for the Raspberry Pi which adds multiple audio inputs and outputs to the low cost ARM Linux board, as it has been widely reported in the blogosphere. I’ve just mentioned it in case you missed it, as instead I’m going to write about a bundle with the Raspberry Pi Model B, lots of expansion boards, cables, and accessories such as a power supply, or a remote control that can be purchased for $120. It may not be useful if you only have a specific project in mind, but if you want to play around and interface with lots of different hardware, or even offer electronics lessons, it could be interesting. The complete kit includes: Raspberry Pi Model B with 512 MB RAM. Acrylic Case for RPi (not shown above) Expansions boards and modules: DVK511 Expansion Board with headers, jumpers, LEDs, and potentiometer 2.2″ […]

Alps Electric Magnetic Field Sensor Measures 1.15 x 1.15 mm, Software Algo Adds Gyroscope Function

I’m really impressed with the recent miniaturization of boards and components. Back in the days (in 2012), many people were amazed at the credit card size of the Raspberry Pi ARM Linux computer. Since then, we’ve seen many other ARM Linux board with similar or even smaller sizes, and on a broader scope, many smaller and smaller hardware and components: Olimex launched OLIMEXINO-85S Arduino compatible board about the size of a micro SD Card, eConais unveiled WiSmart EC19D Wi-Fi module measuring 8×8 mm, Freescale recently announced Kinetis KL03 Cortex M0+ MCU measuring 1.6 x 2.0 mm in its smallest package, etc… Today, I’ve come across another tiny chip, the world smallest magnetic field sensor by Alps Electric that measures only 1.15 x 1.15 x 0.56 mm. Height does matter too. It’s about 60% smaller than previous product by the company, but only slightly smaller than Asahi Kasei Microdevices’ AK09911C which measures 1.2 x […]

DIY Farm & Garden Automation with Arduino and APDuino Project

You would like to start to grow your own vegetables but you don’t really have enough place and/or time to take care of your garden. No problem! Just go vertical and automate your garden with an Arduino Mega, an Ethernet shield, and lots sensors and valves. That’s basically what Rik Kretzinger, who grew up on a Christmas tree farm, and has a major in horticulture, has done at his home. This whole system use a farming technique called aquaponics, mixing aquaculture (raising fish in tanks) and hydroponics (cultivating plants in water), and except planting and harvest, is mostly automatized. The hard part is to set it up. The firmware is based on APduino “Internet-of-growing” open source project that runs on Arduino Mega to gather data from sensors (humidity, temperature, pH, light…) and control the valve. Rik’s system also upload data automatically to Xively cloud so that he can monitor his […]

Google’s Project Tango Phone Prototype Generates Real-time 3D Maps

Google ATAP (Advanced Technology and Products), the team who is currently working on Project Ara for Google, and recently moved from Motorola following the acquisition by Lenovo, has also been busy on another project called Tango, which centers around a phone equipped with cameras and sensors capturing 250,000 data points per second to track motion and generate 3D maps in real-time. The prototype is 5” phone with hardware and software customization designed to simultaneously track the 3D motion of the device, and creating a 3D map of the environment. The device runs Android and includes development APIs to provide position, orientation, and depth data to standard Java, C/C++ Android. This is still early development, but the team imagine the technology could be used to easily create a 3D map of your home, facilitating furniture shopping. Other usa cses include indoor navigations, visually-impaired aid, and product location in a store. Augmented reality […]

ICMe Cuffless Finger Blood Pressure Monitor Sends Results to your Smartphone via Bluetooth 4.0

Nihon University have developed a tiny blood pressure monitor, which you can just touch with your finger, in order to get maximum and minimum (systolic and diastolic) blood pressures, both average and real-time values, as well as pulse rate and pulse waveform displayed on your smartphone. ICMe uses photo transistors to detect LED light reflected on a finger, and then converts pulse wave data obtained from the light to a blood pressure value. Phase Shift Method-based data processing and algorithm is used for the conversion to a blood pressure value, and results are transmitted to the phone via Bluetooth 4.0 (LE?). The device is composed of a custom main chip, LEDs, photo transistors, and a Bluetooth 4.0 module. Tech-on reports an early much larger model was exhibited last year at Medica 2013, and the new miniaturized model is currently showcased at Medica 2013, which runs from Nov 20 to 23, […]
