This is a scan of the complete Bloc-Tronic electronic kit manual. It has 163 electronics projects from a simple continuity tester to a radio transmitter which are arranged roughly in order of complexity. Each project has both the block layout for the kit and a standard schematic so you could build these on a breadboard as well.

On a related note, does anyone have a set of these they would be willing to let us borrow for a bit? I’m thinking that it might be possible to reproduce them in some way…
