This mini metronome gives a linear scaled output and 40 to 208 beats per minute. 1- Q1 and Q2 transistors provide linear frequency variation of IC1 depending on the changes of P1 value. 2- Q3 ...

Like many of us [AnotherMaker] is a fan of the classic Forrest Mims electronics books, specifically, the Engineer’s Mini-Notebook series. They were great sources of inspiration, but at the time, he ...

Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...
