Thanks for a really informative post Saurav. I agree that budgetary concerns do limit what technologies libraries can provide to their users, but at the same time as you started to draw out, there are different ways libraries can still provide access to these technologies. For many users, I think just a talk or presentation about for example 3D printers or Arduino would heplful. I think gaining a basic understanding of the design logics and strategies used in these technologies would also be very helpful to library users.
