Creating a Smart Water Sensor with the ESP32 Thing
https://www.electronics-lab.com/creating-smart-water-sensor-esp32-thing/
Alex the Giant @ sparkfun.com has a tutorial on how to build smart and connected water sensor using ESP32. He writes: For this project, you can use either the ESP8266 Thing, or the ESP32 Thing. One of the many improvements made on the ESP32 is the capacitive touch circuitry built in to ten of the […]

LT8315 – 560VIN Micropower No-Opto Isolated Flyback Converter
https://www.electronics-lab.com/lt8315-560vin-micropower-no-opto-isolated-flyback-converter/
The LT8315 is a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation. The LT8315 operates over an 18V to 560V input voltage range, has a […]
Educational Biomed Shield for Arduino 101
https://www.electronics-lab.com/educational-biomed-shield-arduino-101/
Orlando Hoilett has built his new biomedical Arduino 101 shield: Biomed Shield, in order to allow students, educators, and hobbyists to learn about bio-medicine by monitoring heart rate, temperature, and other physiological metrics. To build this shield he used the following components: AD5933 MLX90614 Microchip Rail-to-Rail Input/Output Dual Op-Amp MAX30101: a specialized integrated circuit that is able […]
Making the Electronics for CDM324 – 24GHz Doppler Motion Sensor
https://www.electronics-lab.com/making-electronics-cdm324-24ghz-doppler-motion-sensor/
limpkin @ limpkin.fr tries out the CDM324 / IPM165 Doppler effect sensor and proposes an amplification circuit to get the readings out of the sensor. He writes: You may recall the article I wrote a couple of years ago about a nearly identical Doppler sensor, the HB100. While the HB100 is using a 10.525GHz frequency, […]

MKRFOX1200 is a powerful board that combines the functionality of the Zero and SigFox connectivity. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking having a low power device. Arduino MKRFOX1200 has been designed to offer a practical and cost effective solution for makers seeking to […]
10 or 12-bit DAC from the ATtiny85
https://www.electronics-lab.com/10-12-bit-dac-attiny85/
David Johnson-Davies @ technoblogy.com writes: This article describes how to get up to two 10 or 12-bit digital-to-analogue outputs from an 8-bit Timer/Counter, such as in the ATtiny85. To test the routine I built a circuit which allows you to vary the brightness of two LEDs with two potentiometers: 10 or 12-bit DAC from the […]
