Arduino Watch With Altitude, Temperature, Compass And Pedometer
https://www.electronics-lab.com/arduino-watch-with-altitude-temperature-compass-and-pedometer/
by benhur.goncalves @ instructables.com: Hi folks! Last few days I’ve been obsessed with the idea to make my own watch from arduino parts, but something cool I could use and say I did it myself. So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 […]
Externally clocking (and overclocking) AVR MCUs
https://www.electronics-lab.com/externally-clocking-and-overclocking-avr-mcus/
by nerdralph.blogspot.ca: People familiar with AVR boards such as Arduinos likely know most AVR MCUs can be clocked from an external crystal connected to 2 of the pins. When the AVR does not need to run at a precise clock frequency, it is also common to clock them from the internal 8Mhz oscillator. Before CPUs were […]
ESP8266 Weather Station with Arduino
https://www.electronics-lab.com/esp8266-weather-station-with-arduino/
by ohneschuh @ instructables.com: I read about the ESP8266 first in March this year and I didn’t know what to do with. And now I’m really fascinated how easy the connection of an Arduino to the Internet can be. Like others I set up a weather station on a breadboard first and sent data to thingspeak.com. […]

Narrowband RF Power Amplifier (520MHz)
https://www.electronics-lab.com/narrowband-rf-power-amplifier-520mhz/
The RF power amplifier stage is usually the final active block of any electronic system that is transmitting RF power. Relatively low power RF signals are amplified to produce a more powerful signal in order to be transmitted over greater distance. RF output power can range from a few mW to MW, depend by application. […]

by Susan Nordyk @ edn.com: Housed in a tiny 2×2-mm, 6-pin DFN package, the MAQ5300 voltage regulator from Micrel boasts a dropout of only 100 mV at 300 mA. The AEC-Q100-qualified part is suitable for space-constrained and high-reliability applications that are subjected to the harsh environments and temperatures commonly encountered in automotive and industrial applications. The […]
ESP8266 MQTT battery monitor project
https://www.electronics-lab.com/esp8266-mqtt-battery-monitor-project/
Steve’s latest project, a wireless MQTT battery monitor: This board uses an ESP8266 (ESP12), a Texas Instruments INA226 I2C voltage and current monitor, and a Texas Instruments LMR12010X buck converter. This board is designed to wirelessly monitor 12 volt batteries and power supplies using an external current shunt resistor. The voltage across the shunt resistor […]
