Ambient light and proximity sensors sense distances up to 10cm
https://www.electronics-lab.com/ambient-light-proximity-sensors-sense-distances-10cm/
With its APM-16D17-05-DF8-TR8 and APM-16D17-06-DF8-TR8 ambient light and proximity sensors, Everlight aims to save energy and reduce unwanted signals and noises when used in smartphones, tablet PCs, residential smart lighting and digital signage applications. [via] Both series use a specially coated photo diode with an optical response similar to human eyes. They have a common […]
EmbeddedLab introduces us TI’s Tiva C MCUs
https://www.electronics-lab.com/embeddedlab-introduces-us-tis-tiva-c-mcus/
Shawon Shahryiar @ embedded-lab.com introduces us to Tiva C series microcontrollers from TI. The Tiva C series MCUs are high performance ARM Cortex M4F micros. Now what does that mean? Generally speaking the ARM Cortex M series is meant to be used in place of (or simply replace) regular microcontrollers like PICs and AVRs while […]
Inside the tiny RFID chip that runs San Francisco’s race
https://www.electronics-lab.com/inside-tiny-rfid-chip-runs-san-franciscos-race/
Ken Shirriff teardowns an RFID chip used to track the time each runner took to run the race. At the beginning and end of the race, the runners cross special mats that contain antennas and broadcast ultra high frequency radio signals. The runner’s RFID chip detects this signal and sends back the athlete’s ID number, […]
World’s First 1,000-Processor Chip
https://www.electronics-lab.com/worlds-first-1000-processor-chip/
by Andy Fell: A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis, Department of Electrical and Computer Engineering. The energy-efficient “KiloCore” chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors. The KiloCore was presented at the 2016 […]

by aniansh @ instructables.com: Have you ever felt like creating one of those city street time lapses that you see on the internet or recording the blooming of a flower through a time lapse or maybe create a night sky panorama of the milky way drifting in the background? Well, now you can do so […]
Conventional Flow vs Electron Flow Explained
https://www.electronics-lab.com/conventional-flow-vs-electron-flow-explained/
“baldengineer” explains which way the current flows. A couple of weeks ago I wrote about four current flow direction myths. As a follow up to that popular post, I decided to dedicate this month’s AddOhms electronics tutorial video to Current Flow. In episode #19, I tackle the question of which way does current flow. You […]
Inside the SDS7012 Oscilloscope: Mainboard Analysis
https://www.electronics-lab.com/inside-sds7012-oscilloscope-mainboard-analysis/
Christer Weinigel has been tinkering with an OWON SDS7012 o’scope, including deciphering the device’s OS and even disassembling the bootloader. Now it’s time to dive in and examine the mainboard, physically, with many of the board’s sub-circuits explained. via adafruit.com Except for soldering some wires to the JTAG and serial port on the scope, most […]
Wireless Weather Station using Arduino Due, DHT22 sensor and NRF24L01+
https://www.electronics-lab.com/wireless-weather-station-using-arduino-due-dht22-sensor-nrf24l01/
educ8s.tv uploaded a new project on youtube. In this video we build a Wireless Weather Station using the fast and powerful 32bit Arduino Due board. We measure the temperature and the humidity with a couple of DHT22 sensors and we communicate with the remote sensor using the 2.4GHz NRF24L01+ module. Let’s see how to build […]
Count down timer for UV lamps using PIC16F887
https://www.electronics-lab.com/count-timer-uv-lamps-using-pic16f887/
Here is a countdown timer for UV exposure lamps @ cuteminds.com Here follows a simple count down timer useful for the production of pcbs using photoresist and UV lamps. We have used a pic 16F887 Microchip microcontroller; there are no particular reasons, we have simply used the picmicros available at the moment. Count down timer for […]
