Mokacam Alpha, The World’s Smallest 4K Camera

Have you ever imagined to record your life at high quality with a small and an affordable camera? Mokacam, the camera producer company is making this possible. After the success of the first version, Mokacam had launched its new 4K camera, Alpha. Initially, Alpha is a smaller and more powerful version featuring Ambarella processor for 4K video to 120 FPS super slow motion. In addition, Alpha weighs only 79g and is sized 45x45mm.

Alpha is attachable to a shutter wheel to enable you shoot long exposure night photos. In Manual mode, you can turn the shutter wheel to set the shutter speed freely from 1/2000″ up to 32″. Additionally, you will forget completely the need of charging it again. Thanks to the built-in-battery feature, you can expect 4 hours continuous 1080P@30FPS video recording. Otherwise, you can add snap-on batteries and record forever!

Mokacam Alpha captures brighter image with more details under low light environment. The Ambrella image processor and the 1.55μm Sony image sensor provides features of 4K Ultra-HD or Full-HD 1/5 Speed Slow Motion video with incredible image quality.

Amazingly, Alpha was live on a crowdfunding campaign on Indigogo and it reached 1200% of its goal! You can check the official website and the product page for more details. Finally, you can pre-order Alpha now for $215 as a limited edition.

Keysight Technologies’ E36300 series bench power supplies

Martin Rowe @ edn.com presents the new Keysight E36300 bench power supply with triple output and some great features.

Keysight Technologies’ E36300 series of bench power supplies provide three outputs with power of 80 W or 160 W with line/load regulation of 0.01%. Front-panel buttons let you turn any output on or off and you can configure each output with 2-wire local sensing or 4-wire remote sensing. The 4-wire sensing removes losses caused by IR drops in your power-delivery wires.

Tri-axis sensor embeds pedometer

Susan Nordyk @ edn.com discuss about the Kionix’s accelerometer with integrated pedometer.

The K126 16-bit tri-axis digital accelerometer from Kionix integrates a step detector and step counter, yet minimizes power consumption. Housed in a tiny 2×2×0.9-mm LGA package, the K126 offers user-selectable g ranges of ±2 g, ±4 g, and ±8 g and output data rates of up to 25.6 kHz.

Breadboard Friendly ATTiny85

Chris @ chris3d.com build his own Attiny85 board:

 The modularity of Arduinos is great, but after playing with them for a year or so, I wanted to start building things that needed a little more integration. I also wanted to design the components and programming around the actual controller I’d be using. So, I decided to start by building a small breadboard friendly ATTiny85.

Inteligent Power Module (IPM) Board for Brushless Motors

Intelligent Power Module (IPM) board has been designed using FSBS5CH60 IC from Fairchild, which provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s internal IGBTs. Separate negative IGBT terminals are connected to shunt resistor to provide the current feedback to the micro-controller. This IPM module helps to develop lots of power applications and also can be used as H-Bridge for brushed DC motor. The module is manly helps to drive Hall sensor based or encoder based motors, it doesn’t support FOC algorithm, FOC based IPM board is under development and will be publish soon.

A 5nm GAAFET Chip By IBM, Samsung & GlobalFoundries

In less than two years since making a 7nm test node chip with 20 billion transistors, scientists have paved the way for 30 billion switches on a fingernail-sized chip. IBM with its Research Alliance partners, GlobalFoundries and Samsung, have unveiled their industry-first process that will enable production of 5nm chips.

The new 5nm technology is one of the first ICs based on GAAFET (Gate-All-Around) topology transistors and also probably the first serious application of EUV (Extreme UltraViolet) lithography.

Gate-all-around FETs are similar in concept to FinFETs except that the gate material surrounds the channel region on all sides. Depending on design, gate-all-around FETs can have two or four effective gates. Successfully, Gate-all-around FETs have been characterized both theoretically and experimentally. Also, they have been successfully etched onto InGaAs nanowires, which have a higher electron mobility than silicon.

IBM claims that it can fit in up to 30 Billion transistors on the chip using GAAFET on a 50 mm² chip. It’s a big move in the semiconductor world, as designs become increasingly complicated to apply. While comparing 5nm GAAFET to 10nm commercial chips, it will achieve a 40% performance boost and a 75% power consumption reduction, at similar performance levels. These are some big claims, so expect some big changes just around the corner.

“For business and society to meet the demands of cognitive and cloud computing in the coming years, advancement in semiconductor technology is essential,” said Arvind Krishna, senior vice president, Hybrid Cloud, and director, IBM Research. “That’s why IBM aggressively pursues new and different architectures and materials that push the limits of this industry, and brings them to market in technologies like mainframes and our cognitive systems.”

Flexible Smartwatch

A 2.5mm thick flexible smart watch with e-ink display, BT 4.0, and health sensors. by Nick Ames @ hackaday.io:

This project aims to build a thin, flexible smartwatch. It’s wrap-around display and touchscreen will allow it to display more data at a glance than current devices. Besides telling time and displaying notifications, the watch will feature pulse rate, blood oxygen, and step sensors for health monitoring.
