I am working on a project with my son (12), and we would like to make individual logic gates that can be wired up easily into various combinations. Something like the Snap Circuits components, but with logic gates. We will need a lot of them - perhaps 30 gates of various types.
I know that we could design and make small PCB boards, and mount an IC and connectors on each, but I'm not sure how to handle the power supply. In an ideal world, I'd like to have students just hook up the signal wires and not be bothered by power.
I have searched, but aside from a some very expensive sets with very few gates, I have not found anything. Is such set of logic gate components available? Or does anyone have a proven design for constructing such components?
