The LED connects across the output transistor because this approach lets the inductive kickback voltage add to the battery-supply voltage and makes the LED brighter. This circuit operates well from ...

“The LED may also flash when the E and C leads are switched, but the flash rate will be faster,” Gerbig explained. “This reflects the fact that some types of transistor will operate with their emitter ...

Curious how a solar-powered lamp powers an LED with just a single 1.2-V cell? In a 2012 edition, Elektor presented a clever single-transistor voltage converter circuit by Burkhard Kainka. Let's ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more ...

Witness how transistors work together in intricate circuits, powering the systems that run code, execute commands, and drive all your digital experiences.

A new simple two-transistor four-dimensional (4D) chaotic oscillator is proposed using two sub-circuits, i.e. a modified single-transistor Colpitts oscillator, and another single transistor ...
