Hi, Ian, welcome to the show er place. {^_-}
Doesn't pay MY wages or even my retirement. I designed electronics, notably significant assemblies on the GPS satellites and military and civilian satcom equipment until I started developing software for both show control and broadcast station video playout and effects.
I had my tongue firmly emplanted in my (thinks back) left cheek at the time.
(Way back in the 60s I rather wished I could be a pilot. But my eyesight without glasses pretty well guaranteed no military flying, which then seemed to be the canonical way into a cockpit job. At the time they ignored the fact that contact lenses corrected me better than 20/12 and I had an accommodation range so wide I could focus on 1 mil gold wires on integrated circuit assemblies. So, I never got there. These days I can't for medical reasons. I still have a LONG time fascination with the concept of flying and the men who can do it safely and well.)
