Hi Paul,
Glad you liked this Course!
The tricorder might be a nice new project for you, you’ll be facing plenty of new challenges and modeling something by yourself, without the guidance of a tutorial is already a lot harder than you’d expect. You should definitely do that, that’s a really good way to learn.
That being said, a cathedral is almost certainly out of your reach at this moment;; first do maybe the Core Modeling and then maybe the Pothead Course. That’ll give you a bit of a basis; You won’t be at the cathedral level though. That is rather advanced.
I’d even dare to say that, as long as you still need a tutorial, you won’t be ready for a cathedral. (Even finding usable reference is hard 😉)
