Providing power via contact-closure circuits historically required a new third wire, but perhaps no longer. Say the words “solid-state relay” (SSR) and most engineers also naturally think of two ...
What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit counter using relay logic with tons of buttons? The register with LEDs and ...

A KiCad clap switch circuit uses a condenser mic to detect sound, amplifying the signal through transistors (like BC547). This triggers an IC—such as a 555 timer or 4017 decade counter—to toggle an ...
