Soldering make bad smoke which is not good for health, so every work table need good smoke remover. To Build Our Own Solder Fume Extractor Circuit uses few easy parts to remove bad smoke, as it uses BC547 transistor, small DC fan, preset resistor, capacitor and NTC thermistor to make air clean and safe. Here, […]
Simple Arduino Based Electromagnetic Field Detector Circuit
EMFs (electromagnetic fields) are invisible energy from electricity and lights which are natural and man made. Some EMFs are safe and some are bad if used too much for long time, so we can use simple Arduino tool to find EMFs around us. Moving electric charge make EMFs and this EMFs have two parts: electric […]
