Post project 21: Simple Sound Effects 2.0
In the May 1979 edition of Elektor we published a “Simple Sound Effects” unit. The author was rightly proud of the design which used a CD4040 counter, a CD4049 Hex inverter and a few odds and ends. Anyone who considered building the circuit all those years ago will be happy to know that a newer version is now available. Thanks to the marvels of modern technology we can now make the same sort of racket but with fewer components. That’s progress!
