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 […]
1.2V-25V/10A Adjustable Power Supply Using Power Op-Amp
https://www.electronics-lab.com/1-2v-25v-10a-adjustable-power-supply-using-power-op-amp/
This is a small size power supply based on OPA549 power op-amp that provides output voltage 1.2V to 25V with 0 to 10A adjustable current limit. Two onboard trimmer potentiometers provided to adjust the voltage and current, LED D1 is over temperature indicator. The circuit works with input supply of 30V DC and logic supply […]

Could Sodium-ion Batteries be a Replacement for Li-ion Batteries?
https://www.electronics-lab.com/sodium-ion-batteries-replacement-li-ion-batteries/
In early 1990s lithium-ion batteries started gaining popularity as a substitute for nickel-cadmium batteries. They have higher energy density, low self- discharge, and low maintenance, but it was soon found that they have short life span, unstability which causes security concerns and creates the need for protection circuits (to maintain it within safe limits), and […]
Using an MMA7455 accelerometer with an ESP32 board
https://www.electronics-lab.com/using-mma7455-accelerometer-esp32-board/
by shedboy71 @ microproducts.net discuss how to use MMA7455 accelerometer with ESP32 board. He writes: The MMA7455L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion […]

Cameron Coward @ blog.hackster.io writes: Like most connected technology these days, near-field communication (NFC) is susceptible to hacking. By its very nature, NFC is normally accessible by anyone nearby. NFC, as it was originally intended, is designed to provide data wirelessly to any nearby readers without requiring a power source of its own. Fortunately, N-O-D-E, […]
Transistors- The 70-year-old invention that changed the world
https://www.electronics-lab.com/transistors-70-year-old-invention-changed-world/
Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum […]
WattUp – RF based Wireless Charging at a Distance
https://www.electronics-lab.com/wattup-rf-based-wireless-charging-distance/
Recently, many big companies such as Samsung have developed wireless chargers which work by induction. These chargers usually consist of a station which needs to be in contact with the device in order to charge. The station defeats the purpose of being able to move and walk while still charging the device. Energeous, a global […]
