ATMEGA328 based Weather Station
https://www.electronics-lab.com/atmega328-weather-station/
Vlad @ denialmedia.ca has build a solar powered weather station based on ATMega328 microcontroller that is able to measure temperature, a humidity, and UV radiation and it uploads measurement on WeatherUnderground network. The data are send to the air using a 433MHz link. The sensors used are DHT22, ML8511, BMP180 and a TP4056 charger IC is used to […]
Arduino Analog Signal Graphing on a TFT
https://www.electronics-lab.com/arduino-analog-signal-graphing-on-a-tft/
dmainmon @ instructables.com has build an analog signal graphing project using Arduino Mega 2560 and a 2.8 TFT display. This project is used to display two analog signals as line and bar graphs. Touching the screen pauses the graph and opens a menu to adjust setting for the graphs. The project uses an Arduino Mega 2560 and […]
Quantifying cooling system
https://www.electronics-lab.com/quantifying-cooling-system/
Chris Palmer has built this coolometer project to measure the cooling effectiveness of various fan: I was wondering about how I was going to calibrate the airflow reading but then realised that the flow rate is not actually what I am interested in. It is the cooling effect the airflow has, which is what I […]

Marko Pavlin has designed a Mini USB dongle with STM32F0xx that is connected to USB and controlled via command line interface. Mini USB dongle with STM32F0xx is suitable many for simple, mini projects. I attached speaker to Timer14 PWM output (Pin PA6) and LED (or optocoupler connected to PTT) to GPIO pin PA0 The provided […]
MAX038 Function generator
https://www.electronics-lab.com/max038-function-generator/
Milen @ instructables.com has designed a Function Generator based on the popular MAX038 and is controlled by ATMega328PU. Signal characteristics are displayed on a LCD screen. The digital features of the function generator were performed by one Atmega328 chip. Its functions are the following: controls the frequency range selection controls the signal type (sine, rectangular, […]
Nixie thermometer
