[Watford] LUG Meeting today?

[Ishaq]

I haven't gathered a huge amount of information, but what I have gathered
so far is documented here:
https://docs.google.com/document/d/1xuxKAHy3DJVmZk-Qmj4OfKzkg6ykFumVrg_ocUXG7zg/edit?usp=sharing

I'll be adding information to it as I go along. After that, I want to
come-up with a design that will at least work on paper before starting
prototyping/experimenting.

Thanks
