Evaluation samples of STMicroelectronics’ STM32F446 range of MCUs are now available. These devices feature ARM Cortex-M4 based processing units with compact 256 or 512 KB on-chip Flash options and 128KB RAM with built-in memory-extension interfaces, extended connectivity and communication capabilities.
The MCUs use ST’s proprietary ART Accelerator, smart architecture, advanced Flash technology and an embedded ARM Cortex-M4 core to achieve a performance of 225 DMIPS and 608 CoreMark at 180 MHz executing from embedded Flash.
The interface capabilities allow simultaneous communication via multiple interfaces which cater for interactive industrial, scientific, medical, and Internet-of-Things (IoT) applications, while the advanced process technology, together with dynamic voltage scaling, extensive clock gating and flexible sleep modes offer significant power savings.

What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed accomplishes just that – without seeing the physical structure of the object, you will still be able to feel the presence of virtual objects.
The goal of the project is to create an exoskeleton on the forearm arm that provides tactile perception for the user. The volume of the virtual object will be emulated based on the intensity of a light source that is placed inside a black box. Depending on the relative brightness of the source to the phototransistors that are mounted onto the exoskeleton, a distance between the user’s hand and the light source can be determined. By varying the brightness of the LED light source, the size of the virtual object will vary. To provide the tactile perception, servos mounted on the exoskeleton provides a pulling force, preventing the user’s fingers from reaching closer to the light source. In addition to the resistive force that act against the fingers’ movement, there are also flat surfaces at the tips of the exoskeleton that will flip up to make contact with the user’s fingers, which actually provides the sense of touching a real object.

Spark has improved and expanded their product line with the Photon wi-fi development board and a pair of new wireless modules for custom circuit boards. The Photon improves on the popular Spark Core microcontroller by adding 802.11n wi-fi connectivity, SoftAP for provisioning, more memory, and a faster ARM Cortex M3 processor. Like the Core, it sits right into a standard breadboard for easy prototyping. And best of all, it can be had for $19.

Find out the WunderBar – the OpenSensor Cloud Platform enabling to easily develop applications for the physical world.
The WunderBar IoT (Internet of Things) Starter Kit from company relayr mimics the appearance of a chocolate bar with a WiFi enabled master module, plus six detachable smart sensor mini-modules.
The WunderBar Internet of Things WiFi & Bluetooth Sensor Starter Kit is a quick start development tool for software application developers unfamiliar with complex wireless hardware designing, and a complete open-source wireless hardware reference design. WunderBar provides to hardware design engineers an out-of-the-box development tool that helps users get started quickly building, inventing, developing, and experimenting with Internet of Things senor based designs using WiFi and BLE senor applications.
Made of seven modules, the WunderBar main module is fitted with an ARM Cortex ‘M’ micro -processor, which connects to the internet through the WiFi unit. Bluetooth Low energy is used to communicate with the other modules. All of the activity that happens around the WunderBar is sent to the WunderBar platform, where you can easily access and work with the signals.
Break, place and program
It works right out of the box. It is energy efficient, fast, secure and designed for developers, makers and manufacturers.
WunderBar has six powerful smart modules, each equipped with its own Bluetooth Low Energy (Beacon) processors and battery that can power the units for up to a year. Light / Color / Proximity, Gyroscope / Accelerometer, Thermometer / Humidity, IR Transmitter (remote control), A connector to the easy Grove System of Sensors and Actuators that are all Arduino compatible and a Noise/Sound sensor. The Starter Kit has available for download various software development kits (SDKs) for iOS, Android and Node.js. including test Apps which can be downloaded from relayr.io. Libraries for node.js, python and more will be supported soon.
WunderBar is the easiest way to create innovative and useful apps to connect smart devices without needing to learn about hardware. App developers can quickly access data from the physical world with WunderBar’s easy-to-use SDKs for iOS, Android and Node.js or with our simple REST API.
Because the WunderBar is still a dev kit, with a little bit of knowledge, and the exposed GPIO pads, you can make almost anything you want smarter. More info at: www.relayr.io/wunderbar The WunderBar will soon be our standard stock item.
