An oscilloscope is a device that measures and analyses signals in circuits. It’s an indispensable equipment for everyone who works with electronic circuits since it enables them to see the activity of a wave in real – time basis. The DSO138 is one of the most popular oscilloscopes on the market today. We’ll give a […]

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, […]
