So my son was playing on his laptop and found a circuit simulation program that is part of GCompris (Open Source Educational software). He “desgined” a simple counter on it, when I saw what he made I asked him if he wanted to make it with real parts… He said yes. A bit of searching in my spare parts drawers and we had resonable substitutions to build a circuit that could count. Yes, he put it together on the breadboard, following the diagram (adapted to the parts we had on hand). See his creation… Next planned upgrade is to make it count by itself (555 timer to the rescue).
