Oscillator Circuits

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 […]

This small and Simple Rain Sound Effect Generator Circuit it like a rain sound maker in box. It uses electric parts to make sound and almost same like real rain drop. This soft sound are good for many things like background music or sleep timer or help us in dreaming. So next time if we […]

Imagine our devices as a little translator! This Simple IC 555 PWM Generator Circuit work like that translator but for signal and electricity. It uses one special chip called as IC 555 to take message and make it like pulse signal. This pulse signal can help control things like light brightness or motor speed. Circuit […]
