Wrist Mount Digital Altimeter
https://www.electronics-lab.com/wrist-mount-digital-altimeter/
This project is a simple wrist mount digital altimeter which is a device used to determine altitude. This design uses atmospheric pressure to calculate the altitude of its location. The lower the atmospheric pressure, the higher the altitude. The project is comprised of a microcontroller (MCU), an 84×84 pixel graphic LCD and a barometric pressure […]
DIY milliohmmeter
https://www.electronics-lab.com/diy-milliohmmeter/
by hwmakers.eu: This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current sense output gives the value of […]

by Graham Prophet @ edn-europe.com: Atmel ATmegaS128 AVR microcontrollers are now produced in space-grade quality, including latch-up immunity, ceramic packaging and extended temperature range for next-generation of space applications. AtmegaS128 – the first µC Rad Tolerant device for Atmel – delivers full wafer lot traceability, 64-lead ceramic package (CQFP), space screening, space qualification according to QML […]
Password Based Circuit Breaker
https://www.electronics-lab.com/password-based-circuit-breaker/
Electrical accidents are rapidly increasing especially electric line repairs incident due to the lack of communication and coordination between the maintenance personnel and the electric substation staff. The password based circuit breaker device could just be the solution as only the lineman could reliably control the circuit breaker to avoid miscommunication. The system requires a […]
9-axis motion sensor and MCU reside in tiny package
https://www.electronics-lab.com/9-axis-motion-sensor-and-mcu-reside-in-tiny-package/
by Susan Nordyk: Housed in a 5.2×3.8×1.1-mm package, Bosch Sensortec’s BMF055 9-aix sensor combines an accelerometer, gyroscope, and magnetometer with a 32-bit MCU to enable easy programming and customization. It can be used by designers creating advanced application-specific sensor fusion algorithms for robotics, gaming, remote controls, navigation systems, drones, and human interface devices for IoT projects.

PIC24 bedside table alarm clock
https://www.electronics-lab.com/pic24-bedside-table-alarm-clock/
Markus Gritsch posted pictures and code of his PIC24 bedside table alarm clock: Another year, another clock, but for the first time for my alarm clocks. I am not using an MSP430 but a PIC24 instead. Standby current is with 5.5 µA only slightly higher than that of my MSP430 based ones. Time keeping is […]
Humidity sensor using 8051
https://www.electronics-lab.com/humidity-sensor-using-8051/
by circuitstoday.com: This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16×2 LCD display. A relay is also provided which is set to be […]

https://www.electronics-lab.com/18-pin-pic-development-board/
The PIC 18 PIN (DIP) Development / Evaluations Board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, 18 Pin PIC16F1847. It can be used as a standalone demonstration board with a programmed part. With this board you can develop and prototype with all Microchip’s 18 PIN PIC microcontrollers. The board has a Reset switch and […]
AC energy metering board using an Atmel 90E24 energy metering chip
https://www.electronics-lab.com/ac-energy-metering-board-using-an-atmel-90e24-energy-metering-chip/
Steve Rodgers writes: Here’s my latest project. Its an AC energy metering board using an Atmel 90E24 energy metering chip. The board can either take an ESP8266-12 and run a native C application, or the ESP8266-12 can be omitted, and an external microcontroller can be used to talk to the Atmel 90E24 energy metering chip.
