I know my mum often wonders what it is I actually do. Fair enough. As an electronics engineer in a specialist niche of the industry, there are no bridges, buildings, cars, or other obvious examples of "I build that". The closest I've come in the past is saying "we build black boxes that go into bigger boxes that people like Boeing put on their aircraft."
Well, last night I had the pleasure of watching "How to build: A Satellite" on SBS. Absolutely fantastic. Although I haven't had the privilege, many of my senior colleagues have been involved in satellite components, and there's a point halfway through that shows about as much of my sort of work as you're ever likely to see on TV.
So if you've ever wondered what it is I really do, take a look at the episode on SBS On Demand. Season 1 Episode 3 if you're having trouble finding it.
