Simple Voltage Controlled Oscillator Circuit
Imagine a small device that make sound like whistle but we can turn one knob to make sound go high or low; this is same like what Simple Voltage Controlled Oscillator Circuit or VCO can do. Also, it is an electronic thing that make signal again and again mostly like in square wave, the speed […]
Simple Low Power Ozone Generator Circuit
Simple Low Power Ozone Generator Circuit use less power, as it make ozone gas from air and it uses electric spark to change oxygen to ozone. Also, ozone help clean air and water and also kills the germs, but too much ozone is also not safe, it can be bad. Circuit Working: Parts List: Components […]
Simple Pierce Oscillator Circuit
Do need very perfect and steady beat for song? then this Simple Pierce Oscillator Circuit is like music tool that gives same note every time but very correct. Also, it uses special crystal like tuning fork to make very stable signal with right frequency and that is why many electronics use it like clocks because […]
Simple Colpitts Oscillator Circuit
Think of a simple Colpitts Oscillator Circuit like a child on a swing; the inductor and capacitors act like the swing system, and they make the signal move back and forth continuously. But swing can slow down also; for that transistor come for help, it is like friend push a kid and keep swing move […]
Simple LED Constant Current Circuit
Just think like water pipe filling bucket. Normal circuit is like set water pressure voltage and hope the bucket fills good, but with LED this Simple LED Constant Current Circuit is like smart nozzle. It keep water flow current same even if pressure changes a little and this way LED light up nice and live […]
