The Astable Multivibrator

In order to create a timing mechanism, you don’t have to have a 555 timer, an IC chip, or an oscillator. With a few passive components and two transistors, you can can an astable multivibrator with two outputs. The video below will discuss how it works, how to build it, and what the output looks […]

555 Timer Output Stage

The 555 timer has many uses and in this video we’ll explore two different ways to utilize the output. First we’ll see how the the timer can be used to source and sink current and secondly we’ll look at a way to use the timer as a control mechanism for another circuit. If you missed
