Do we think about screen on calculator or phone if yes ? then a small translator is needed. Simple Display Driver Circuit is like that translator. Tiny computer, microcontroller gives it information Then driver change it to special code for display. This code tell display which light or pixel should turn ON and to show […]
Simple FET Preamplifier Circuit
This Simple FET Preamplifier Circuit works like super booster for small sound. It uses special transistor, FET to make quiet sound go more loud. This circuit is very good because it uses two kind of transistors N channel FET and PNP bipolar, together they make sound strong and not bad. So even very tiny sound […]
Simple Electronic Component Tester Circuit
This Simple Electronic Component Tester Circuit works like doctor for ones electronic parts. Before we make any cool thing one can use this tester to check parts like resistor, capacitor, transistor and many more. Tester shows if the parts are good or bad so we do not waste time with broken parts in our project. […]
