After checking out Soft Kinetic’s embedded 3D depth camera earlier this week, our attention was brought to a similar offering coming from Germany’s PMD Technologies and Infineon. In fact, we were lucky enough to be the first publication to check out their Cam Board Pico S, a smaller version of their Cam Board Pico 3D …
The new iW3606 and iW3608 single-stage, solid state lighting (SSL) LED drivers from I Watt feature a wide, flicker-free dimming range from 100% all the way down to 1% of measured light, to closely match the dimming performance of incandescent bulbs. This enables the smooth, “natural” dimming, with no light drop-out at the low end …

A versatile kit that can be configured to drive either constant voltage LED arrays or constant current LEDs. Use the kit to dim under-cabinet LED lighting using flexible LED strips or build your own LED desk lamp using High Brightness LEDs. The majority of the circuit is identical for both types of LEDs. Two inexpensive …
LED matrix displays provide flexibility to display text, graphics, animations, and video, and therefore, they have become a popular mean of displaying information these days. You can see them at gas stations displaying the gas prices, or in the public places displaying information, and alongside highways displaying advertisements on large dot matrix panels. This project …

You can use an LED as a photoelectric sensor. A previous Design Idea shows that such a switch is highly power-efficient, consuming almost no power (Reference 1). However, you cannot adjust that configuration to switch at the desired light intensity. You can adjust the circuit in this Design Idea to any threshold level of light …

Plymouth, England – 8th April 2013 – Plessey announced that samples of its Gallium Nitride (GaN) on silicon LED products (p/n PLW111010) are available today. These entry level products are the first LEDs manufactured on 6-inch GaN on silicon substrates to be commercially available anywhere in the world. Plessey is using its proprietary large diameter …
We enlarged our stock offer of well-proven LEDs in a PLCC-2 package with new improved types. KA-3528 series of SMT diodes is not a novelty and many of you may know it already for several years, however this series is being continuously enriched with new types. King bright as a reliable producer of LEDs always improves their specification, …

The solid-state lighting (SSL) surge has created a concomitant boom market for electronics to drive LEDs in various different applications, ranging from incandescent-replacement light bulbs to architectural lighting to streetlights and more. These new driver ICs and modules do more than simply provide power in the form needed by LEDs. Some devices can perform additional …
Meet Powah, a little power on/off toggle with an indicator LED. It uses a pair of Schmitt triggered inverters to debounce the button, and a P-channel MOSFET to switch the power on and off. The board is designed to be plugged into a breadboard. It is designed to mount on one end of my breadboard, …
Seven segment LED displays and discussed about a time-division multiplexing technique that reduces the number of required microcontroller I/O pins to drive multiple seven segment LED displays. Today we will move a step further and discuss about a serial interface (SPI) for driving 8 seven segment LED displays. The technique uses MAXIM’s MAX7219 LED driver …
