[Scott Sullivan]

This is a follow on from my talk back November. Which at the GTALUG this 
evening I gave a small follow up.

At the end of the original talk I discussed having issue with electrical 
isolation on the USB serial adapter. I've since solved that with an 
inexpensive part that's exactly fit for purpose.

Below is the parts list:

* USB-C to Serial Port UART Board Module Isolated USB to TTL Module 3.3V

I also showed off my Build of the Raspberry Pi modular rack, constructed 
from the design by Uptime Labs.

I have a second one of these I printed and assembled but don't actually 
need. If someone interested, I'd sell if for $100 to cover the cost of 
the 5 case fans, steel rod and full spool of filament used in it's 
construction.
