38 DESIGN007 MAGAZINE I MARCH 2022 Sometimes I am envious of those who work with steel, on a construction site, or even till- ing the earth. All these are tangible activities: you mold the steel, build a house, or harvest a crop. Instead, I work in electronics.

Finally, the decision was made to replace a thousand-dollar control module, and after some f i n a l d i a g n o s - tics, the problem w a s r e s o l v e d ; or s o e ver yone thought.
