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 […]
Programmable CW Morse beacon
