Supply chain has become the bane of my existence.
I am no longer an engineer but a manager of parts and pieces for my design.
Instead, I harangue vendors, I scrub Bills-of-Material, I harass software, mechanical, hardware for delivery dates. I am no longer an engineer.

I do look with excitement toward getting a hand-full of Raspberry PI. Maybe orders will open up next week on March 14, PI day, maybe.
