In the following order:

Time - the enemy of us all, essentially. I instead focused my attention on my EE knowledge and in particular focusing on my CAD skills. I feel the basis for Tortuga is very sound and very do-able, I do plan to come back to something of a similar theme in the future but on its own dedicated PCB. I will probably stick to the ESP32 platform though.

Workspace - I don't have a dedicated workspace and share the space with my family, this isn't the most congruent for a good work flow. It's something I'd like to re-visit at some point, co-working maker spaces in my area are few and far between, independent renting is not an option and nor is taking over a communal family area for my exclusive use. 

Prototype - The prototype ended up being at best "sufficient", I don't like sufficient. 

Ultimately, what I guess I'm saying in a lot of words is, I'll come back to this, but not particularly this.
