@unfa man, i'm so with you on this. no, i don't care about portable lights, but i desperately want to learn practical #electronics (got a bachelor's in electronics from those soviet times, useless as i had never touched a live mcu during studies!) and thus try to play with every #arduino howto or tutorial i can find & understand… but there's a huge gap between simple lessons (lady ada) and any «real life» application :-/
