This time, however, [Tim] decided to actually show how this can be done by removing some of the integrated circuits from an electronic dice and relying entirely on the 555 timer for his build.

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...
