Introduction In the previous tutorials, an important link has been established between the conduction angle of an amplifier and it’s efficiency. Indeed, high conduction angles-based amplifiers offer a very good linearity such as the class A Amplifiers but present a very limited efficiency, generally around 20 to 30 %. As the conduction angle is decreased, […]

William Dudley @ dudley.nu has designed a motorcycle headlight modulator based on 555 timer IC and photoresistor. A headlight modulator will make the headlight to pulse during the day and be steady at night. He writes: Unhappy with a headlight modulator I purchased, I decided to make my own. Even though it would be a trivial […]
