Internet connected home energy monitor

FMO23JPI8PQWE4X.MEDIUM

by TheSpodShed @ instructables.com:

This is a magic box which will let you monitor the power consumption of your house from anywhere on the Internet! It measures both true power (Watts) and apparent (VA) power, it keeps a running total of electricity units used, and measures mains frequency as a bonus.

The project uses a Particle Core(*) module – a little board with an ARM microprocessor and a Wi-Fi interface – to do all the hard work. To build it, you’ll need to be able to solder and follow a simple circuit diagram. At UK prices, total parts cost should be no more than £50.

by elektor.com:

Toshiba has added a new variant to its TX04 range of microcontrollers. The TMPM46BF10FG is targeted at IoT applications and incorporates dedicated hardware to implement a true random number generator (TRNG: SP800-90C standard) through the combination of a random entropy seed generation (ESG) circuit and Hash-DRGB created by the secure hash processor (SHA) and software program. These features offload computational overheads on the main processor and meet the standards of security required for network communications.

Based around an ARM Cortex-M4F core, with a maximum operating frequency of 120 MHz, the TMPM46BF10FG incorporates 1024 Kbyte of flash memory and 514 Kbyte SRAM required for secure communications control, four types of security circuits for network communications. The MCU also integrates an SLC NAND flash memory controller and 4- and 8-bit error correction circuitry (BCH ECC) that supports memory expansion with 1Gbit to 4Gbit SLC NAND flash memory chips.

by elektor.com:

ARM has unveiled the new ARM Cortex-A72 processor which they expect to be the standard SoC in mobile devices hitting the marketplace in 2016. Their claim is that it is the highest performing CPU technology available for developing mobile SoCs today. In target configurations, the Cortex-A72 processor is said to deliver CPU performance 50X greater than the leading smartphones from just five years ago.

The ARM premium mobile experience IP suite also offers a significant graphics upgrade offering users up to 4K120fps resolution. Alongside the Cortex-A72 processor is the new CoreLink CCI-500 interconnect and the new Mali-T880 GPU, ARM’s highest performing and most energy-efficient mobile GPU, along with Mali-V550 video and Mali-DP550 display processors. To further ease chip implementation, the suite also includes ARM POP IP for the leading-edge TSMC 16nm FinFET+ process.

Toshiba Announces Two New ARM Cortex-M4F Based Microcontrollers

6627A_HRES

Toshiba has added two new products to their ARM® Cortex®-M4F based TX04 series microcontrollers. The TMPM470FDFG and TMPM475FDFG are both capable of operating two brushless DC motors simultaneously.

The new microcontrollers aim to satisfy ever-increasing demand for more energy efficient motors and incorporate vectoring technology to ensure efficient motor control. The TMPM475FDFG also integrates a CAN (Controller Area Network) controller which is required for use in specialist factory automation systems. Both chips are ideal for a wide range of uses ranging from industrial applications to use in home appliances, such as washing machines, fridges and air-conditioning units.

The TMPM470FDFG and TMPM475FDFG are based upon the high-performance ARM® Cortex®-M4F and can operate at up to 120MHz. They incorporate two modules, each containing a programmable motor drive, 12-bit AD converter and vector engine, ensuring the efficient and simultaneous operation of two brushless DC motors from a single chip.

ARM PRO MINI

arm_pro_mini

ARM PRO MINI is a small barebone open source ARM M0 microcontroller board that is great for quick prototyping and as a starting point for your own ARM based custom designs. It was designed and named after the venerable Arduino Pro Mini and it is an excellent stepping stone for makers and hobbyists ‘graduating’ from Arduino to the ARM architecture.

Two new MCUs from Atmel

AtmelG54_G55

by elektor.com:

AtmelCorporation have announced two additions to their SAM G series of ARMCortex-M4-based MCUs. The two latest models are designated the SAM G54 and SAM G55. They feature high performance (up to 120MHz), low-power (102 µA/MHz in active mode, down to 5 µs wake-up) and tiny outline (as small as 2.84 x 2.84mm). Both are targeted at IoT applications and include all the features of the current SAM G family of devices including an Atmel | SMART ARM Cortex-M4 MCU + FPU (floating point unit) together with integrated sensor fusion algorithms.

The STM32F446 from STMicroelectronics

Impressionby elektor.com:

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.

Feeling the light in a whole new way

IMG_2494

by Mark (Moonyoung) Lee & Kevin J. Wang:

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.
