Some time ago, I reverse-engineered a low-cost inverter made by Vector Mfg. (now Black & Decker). It uses a classic 2-BJT astable multivibrator (AMV) but with a circuit design twist, as shown below.

There are 3 types of multivibrators: astable, monostable, and bistable. This astable multivibrator is an oscillator that generates rectangular pulses. It uses transistor switches and RC networks. The ...

We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say ...
