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 ...

Adding the long-first-pulse malady in less traditional 555 astable topologies including CMOS- and bipolar-based oscillators that generate 50:50 symmetrical square waves. Figure 1 The problem—the first ...
