Transistor Common Collector
A BJT common collector amplifier is a circuit in which the collector and the base of the BJT share a common input supply, hence the name common collector. In our previous articles we have learned the other two transistor configurations, namely the common-base and the common-emitter. In this article I have explained the third and […]

Wireless Music Level Indicator Circuit
A wireless music level indicator is an electronic device built for sensing the varying levels of a music signal and convert it into corresponding levels of illumination over an LED array bar. This simple circuit will create dazzling LED light effect by detecting any music frequency in the atmosphere and by illuminating a 10 LED […]
3 Best Joule Thief Circuits
A joule thief circuit is basically an efficient, self-oscillating voltage booster circuit, built using a single transistor, resistor and an inductor, which can boost voltages as low as 0.4 V from any dead AAA 1.5 cell, to much higher levels. Technically it may seem impossible to illuminate a 3.3 V LED with a 1.5V source, […]
