The Braun Lectron was an electronics kit designed in the 1970s by Dieter Rams, whose minimalist aesthetic was hugely influential to Steve Jobs and Jonny Ives. The Lectron was also Arduino co-creator Massimo Banzi’s “Rosebud.” It not only got him interested in electronics, it also shaped his ideas about design. This fascinating 20-minute documentary about Arduino was produced by Wired Italy. It’s in Italian but is sub-titled in English.
