3D printing has made it possible to fabricate your own electronic devices.
Suppose you could 3D print a digital-to-analog converter of the binary weighted type or R-2R type? Constructed from a network of resistors, with particular ohm values.
Because to home-brew it is tedious. The more bits we want, the more resistors we need and the more tedious the soldering work.
Maybe half a line of description is not sufficient.
What about spending a couple of minutes to write a 5-10 lines post full of informations and your ideas?
Vague question... hm.. you could do a research on supply noise rejection of different DAC architectures with same main parameters, or how components contribute to supply noise supression of different architectures. Just an idea. And probably someone has already did it, DAC is well explored area of IC design. You should browse on IEEE or similar sides to collect trends and ideas.
