Multivibrator is probably the one most interesting things to start electronics explorations; it is one of the simplest circuits that does something by its own, it blinks. And a blink can be considered ...

A typical multivibrator that operates in astable mode is capable of driving an LED with the use of a single cell. The ability to use a 1.5V cell to light up a LED is a big challenge since the forward ...

[michimartini] over on Hackaday.io loves playing with multivibrator circuits, and has come across a simple example of a ring oscillator. This is a discrete transistor RC-delay design utilizing five ...

My teacher friend was looking for Christmassy technology ideas for a science + engineering club. And I said that flashing leds might be good, and if you can get three phases going, you can have a ...
