First thing to come to mind; My (private) rooms lacked capacity to sustain the hardware aspects of a large project. That was after a bit of a 'crash' in resources.
Somewhat in isolation, particularly due to IP concerns (intellectual property, on innovation). Not so much on the technology, building mechanical elements for a completely mechanical computer (firstly for teaching and STEM type student introductions).
Rather, than IP on the devices, my concern was keeping that business model a bit quiet. The IP stuff actually had an emphasis on covering many 'bases' as they say...to prevent some other larger entity from getting their own Patent(s) on associated devices / methods.
In other words, I threw in 'everything but kitchen sink' in my own Patent (applied for) application. Not for eventually IP protection, but simply to clear a setting where I could operate and grow, without some other, big, entity interference.
So, I've ended up here, 2024, with issues more along the lines of isolation (an 'isolated project's, like OP stated). Hard to justify years and years of R&D progress, in a vacume with lack of real market involvement.
I figure, can't really SELL the hardware with any significant quantity market; maybe best to start an education oriented 'Training' system, as the business profit, while the mechanical computer itself being a tool, along with publishing various manuals and training aids
Not your usual 'IC or transistor' manufacture, for sure.
I'm reading your thoughts on how you (OP) present, or attempt to present ideas to others, as you likely need the support. So, it seems a dilemma between needing isolation, meanwhile also needing support.
Plus, in my case, the teaching system project is heavily oriented to things old, now; The 8-bit processor types, of 1970's, and engineering culture, of 1980's...that's now 40 years + !
Can you (OP) find someone, a partner or investor, that fills in the skills you maybe lack...(A 'spokesperson' or marketing type that can spend the time, to hear your concerns and, uh, TRANSLATE, to a more compact expression.
I've encountered others, friends and family, who do the kinds of work that I had anticipated doing, (as a STEM or technical beginners training organization) maybe sometimes just in the similar spirit, which has lots of 'inspiration' or engagement....a difficult item for teachers, often.
