White lighting LEDs are almost universally a combination of a blue light-emitting InGaN die and a phosphor that steals some of the blue light and converts it into a broad spectrum peaking at yellow or amber. The combination of blue light and yellow light looks white to humans. But where do the phosphors come from? […]
Measuring performance of audio components like microphones, speakers, converters, and amplifiers can be a difficult task. In this post, I’ll talk about some of the tools I use to make this job easier. Analyzers, reference transducers, calibrators, meters, and more come with various feature sets and price tags. The items below just happen to be
It is possible to reconfigure radiation-hardened Xilinx FPGAs with the reliability required for space applications, writes a team of developers from Germany-based Fraunhofer IIS RF and microwave design department In 2017 the experimental Heinrich Hertz communications satellite (H2Sat) commissioned by the German Federal Ministry of Economics and Technology will be launched into space, to support
Lumileds has announced a lime green LED, revealing that it a key component in the ‘Hue’ range of colour tuneable LED replacement light bulbs from Philips (which owns Lumileds. Efficacy is the highest yet from Lumileds – over 200 lm/W at the top end of the highest bin – attributed by the company to lime

App note from Microchip on their EL lamp drivers circuits utilizing (Supertex) HV823 and HV825, App note here. This application note presents fourteen EL driver circuits utilizing the Supertex HV823 and HV825 drivers. They have been optimized for a variety of applications and may be used as-is or used as a starting point in designing
After years of wondering when flexible displays would finally emerge, they jumped out at opposite ends of the size spectrum from Samsung and LG within a few months of each other. And they were all on show in Las Vegas earlier this month at the Consumer Electronics Show (CES). At the small end were bendable
A processor is a collection of logic circuits that is designed to efficiently process data. There are a number of processors – processor designs are created for specialised tasks, these include the Central Processing Units (CPU), Graphics Processing Units (GPU), Physics Processing Units (PPU) or Digital Signal Processors. An array or vector processor solves computational

What’s inside the new Pebble Time Smartwatch? Dave does a teardown after taking it through the torture test, and gives it a close up view with the Tagarno microscope. How easy is it to disassemble and replace the battery? How much do the components cost? What is the manufacturing quality like? How does the Bluetooth
JeVois, which can be translated from French as: I see, is an open-source quad-core camera that can be connected easily with your project whether you are using Arduino, Raspberry Pi or just running it on your PC. JeVois contains a video sensor, quad-core CPU, USB video and a serial port in only 1.7 cubic inches.
Traditionally, asic developments are thought to be the domain of high volume applications. Whilst these designs grab the headlines there are many designs that are successfully undertaken for smaller volume product markets. An example of this is the mixed signal asic for industrial controllers. These controllers cover many industries and come in many forms. The
