It occurs to me that here we have a project which doesn't just have a prototype but is actually production proven, and in the words of someone I can't recall, all that's needed is to click the button on the manufacturers website and hey presto!
Yet here we are with
another delay, on top of the previous speed bumps. Completely unforeseen, etc. Were it not Dave doing this I suspect there would be elements of 'yeah, yeah, heard that one before' and perhaps a posting in this very topic.
Don't forget that this is as simple as it could be: a trivial PCB without any components whatsoever. 95% of the posters here could have run one off themselves, or panelled the gerber onto their next PCB.
Please note that I am not trying to diss Dave or his ruler or this round of crowdfunding. What I am trying to do is point out that an apparently simple-as-can-be project can suffer this kind of stuff, and we should bear that in mind when a much more complex project seems to be a straight-up scam.
