Oscillator Circuits

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. It is an electronic thing that make signal again and again mostly like in square wave. The speed of […]

We need very perfect and steady beat for song? Simple Pierce Oscillator Circuit is like music tool that gives same note every time but very correct. It uses special crystal like tuning fork to make very stable signal with right frequency. That is why many electronics use it like clocks because it keep rhythm same […]

Simple Hartley Oscillator Circuit is like small sound maker with electric. It make smooth sound like whistle and does not stops. It is use coil with center tap like two coil join. One capacitor help keep sound going. Need one active part to make sound strong. This sound circuit is different from others. Circuit Working: […]

Think about a Simple Colpitts Oscillator Circuit like small kid on swing. Inductor and capacitor like swing are set as they make swing go back and forth. But swing can slow down. For that transistor come for help. It is like friend push a kid and keep swing move nice and steady. Same way Colpitts […]

In this post we will give all easy information about Simple Water Softener Circuit This one small device we can put on our water pipe which will help to make hard water to become soft. Hard water make white stuff build up in pipe and machine and this make them not work good and cost […]

This Simple Pulse Position Modulation Circuit using IC 555 uses one special chip with number 555. It works like messenger for your electronic things. It send info by making small burst like electric pulse. Not like Morse code with dot and dash but this one uses timing change of pulse to talk. Pulse strength and […]
