So I think this falls under "everything engineering" feel free to flog me with a wet noodle if you disagree. So I've been invited to speak at my sons career day... So I get about fifteen minutes to wow about 30 six year olds. Now, I know we're the type of people that can get excited discussing the arcane details of processor instruction sets. Somehow I can't see a room of six year old sharing my enthusiasm. :-) I'd rather not revert to a Jacobs ladder to get their attention, but I will if I have to. I have about a month to prepare, minimal budget and an "above average" junk box.
