Drishti: For Airport Visibility Measurement

This highly-precise and cost-effective transmissometer developed by Council of Scientific and Industrial Research-National Aerospace Laboratories (CSIR-NAL) is a significant contribution to the field of electronics and airport instrumentation in India

Whitepaper:Low-cost solution for measuring input power and RMS current

This article provides a novel, low-cost but accurate solution for measuring input power and RMS current. It utilizes the existing digital power-factor-correction (PFC) control chip and hardware, with simple two-point calibration and optimized mathematical calculations. This provides excellent measurement accuracy and greatly reduces the cost and design effort, while having no impact on normal PFC control.

Whitepaper:Wireless connectivity for the Internet of Things

In the rapidly growing Internet of Things (IoT), applications from personal electronics to industrial machines and sensors are getting wirelessly connected to the Internet. Covering a wide variety of use cases, in various environments and serving diverse requirements, no single wireless standard can adequately prevail. With numerous standards deployed in the market, spreading over multiple frequency bands and using different communication protocols, choosing the right wireless connectivity technology for an IoT application can be quite challenging. In this paper we review the predominant wireless connectivity technologies in the market, discuss their key technical concepts and engineering tradeoffs and provide guidelines for selection of the right wireless technology for different applications.

A Wearable Drone That Launches Off Your Wrist To Take Your Selfie

The Nixie aims to solve that. It’s, as crazy as it feels to type this, a wearable selfie drone. A flying wristband, with a camera built in. When you’re ready for your close-up, it launches off your wrist, reorients to frame you in the shot, and then hovers back over for you to catch it.

Raspberry Pi: A Tinkerer's Dream Come True

The Raspberry Pi has spurred so much interest in last one year that we decided to uncover what makes it such a great catalyst for innovation

Wear Your Future

"During a Formula 1 race, a driver experiences wrenching forces of more than 4.5G. His heart rate may exceed 180 beats per minute and his blood pressure could rise by half. With soaring temperatures inside the cramped cockpit he will also dehydrate, typically losing 2-3 litres of water during the race. Yet the driver must concentrate well enough to achieve lap times that might vary by just a tenth of a second. This is tough, on both mind and body. Hence it is not just the performance of the car itself which an array of sensors keeps an eye on, wirelessly transmitting data about the engine, suspension and so on to the pit crews. The drivers’ own vital signs are constantly monitored, too." —Economist

Robots That 'Grow Up'

Programming devices - and robots - to do stuff is no longer exciting. The next thing on the wish list is robots that learn how to behave and do things autonomously, just like humans and animals learn as they grow up
