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.
