Has a good article on the 4.  May be able to use these ideas for part 1.  An image from that article:

Can use my asus cardboard box for part 2 yes

Hats - never used any other than the purpose built one for Camosun.

OS and GUI - mostly Debian.  Thoughts on what to describe.

What is "my 4-6"?

I like Craig's idea of node red.

We only have an hour and a half and I think we should leave at least 20 minutes for questions/interruptions.
