https://www.electronics-lab.com/ezpixel-upcoming-fpga-based-ws2812b-controller-board/
FPGAs are field programmable gate arrays which basically means they are reconfigurable hardware chips. FPGAs have found applications in different industries and engineering fields from the defence, telecommunications to automotive and several others but little application in the maker’s world. Mostly, as a result of being largely difficult and high cost as compared to the likes […]
Osram Develops LED Beam Array Smart Headlamps That Can Analyze Road And Traffic
https://www.electronics-lab.com/70849-2/
After over three years of research and field demos, a prototype of Osram’s EVIYOS smart, controllable, high resolution LED automotive headlamp was introduced at the International Symposium on Automotive Lighting earlier this year in Darmstadt, Germany. This smart LED headlamp is able to control its 1,024 LED “pixels” individually. The basic component of the EVIYOS combines an LED […]

A dual-channel step-down LED driver, the LT3964 from Linear Technology packs 40 V, 1.6 A power switches and an I2C interface for dimming control. [via] Operating over an input voltage range of 4 V to 36 V, the driver integrates two independently controlled LED drivers that switch at up to 2 MHz. Synchronous operation results […]
Wi-Lamp, the Open Source Wi-Fi LED lamp
https://www.electronics-lab.com/wi-lamp-open-source-wi-fi-led-lamp/
LucaBellan @ open-electronics.org discuss about a multi-function LED lamp that is always connected over WiFi. Since several years already, it is possible to find systems for home automation: irrigation, doors and windows, lighting, air conditioning and alarm systems, everything can be centralized and planned. Recently, the classical control boxes have been replaced by smart systems […]

Under the “Power by Linear” branding it recently created for the product lines it acquired with its purchase of Linear Technology, Analog Devices has added the LT3964, a dual channel, 36V, high efficiency, synchronous, step-down LED driver with internal 40V, 1.6A power switches and an I2C interface that simplifies LED dimming control. 36V, 2-ch, 1.6A […]
COLIBRÌ: the driver for RGBW LEDs
https://www.electronics-lab.com/colibri-driver-rgbw-leds/
Boris Landoni @ open-electronics.org designed COLIBRI, a board able to drive 4 color LEDs. He writes: Recently some multicoloured power LEDs have appeared on the market and, differently from the more common RGB LEDs, they incorporate a white LED, as an addition: they are named RGBW (Red, Green, Blue, White) just because of this. They […]
LED Heart Keychain
https://www.electronics-lab.com/led-heart-keychain/
Sasa Karanovic @ sasakaranovic.com build a heart shaped keychain that flashes 2 LED with the touch of your finger! Source files are available on github. This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It […]
