“Dieter Rams and Jurgen Greubel designed the Braun Lectron System (1967- 69) as a teaching tool for use in schools and universities. It is made up of a large range of little bricks, like dominoes, that magnetically connect to one another. Once the blocks are organized on a conductive plate, they can form a variety of functional circuits. See this great article on it from a 1967 issue of Electronics Illustrated, where they discuss “what a drag” it is to make your own circuits, but “now it can be as much fun to put electronic circuits together and to learn fundamentals as it is to put words together when you play Scrabble.””
