One of the coolest things about being both an engineer and a photojournalist, is that I get to talk with my engineering colleagues about what they are doing. These conversations often turn into geek-fests — as was the case with Abound Solar’s Tim Barry. He used to work for Atmel Semiconductors that made the really cool (and cheap!) microcontroler I used for a greenhouse control system I developed in the late 90’s. Sharing the excitement for his new gig in the solar business helped defuse the fact that I had a big fat 16-35mm lens pointing at him.
