One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...
The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...
Editor’s Note: Hans Camenzind was selected for the Engineering Hall of Fame in our inaugural induction, which appeared in our 50th Anniversary issue in 2002. He died on August 8, 2012. His son, Peter, ...
This electronic switch allows you to control an electronic device by only clapping your hands twice. It is based on three integrated circuits; 741 Op-Amp, 555 timer, and 4013 dual D flip-flop. A 9V ...
