Today on
Modern Mechanix we have this ad for a 1968
electronics kit for children composed of little magnetic blocks with embedded electronic components. You just stick them together in different ways to make different devices like a radio or electronic organ. This
cutting edge family all got hooked on a teletype installed in their house in 1970 using it for everything from meal planning to (of course), gaming. We also looked at a tiny
hot-water bottle meant to alleviate tooth aches, an odd plane with a
circular wing, a backpack mounted tv
camera and transmitter and the tricks used by
demolition crews.
Had one of the magnetic-contact electronic kits, The upside is that you couldn't fail due to loose connections. The downside is that since the connection possibilities were so limited, there was virtually no room to experiment.
I had the Lectron cubes also, I REALLY had fun with it. That and the Digi-Comp plastic mechanical computer were two of my all time favorites.
