It would be fun to have something like Advent of code, but for arbitrary restrictions.

The grand finale could be making something without using a computer at all or buying anything (Not even for research, you have to use actual books or talk to people), and trying to use as little tech as possible.

Like, you can use a power drill, but if you use a brace and bit you get extra points. You can document with a phone camera but if you can draw you might want to illustrate instead.
