I know of a couple other resources. First and foremost is the site modernnomographs [1]. Popular mechanics once included a perpetual calendar nomograph [2]. Possibly pynomo [3], a python tool to make nomographs, would also be interesting to others.
I made a nomogram of the electromagnetic spectrum many years ago using pynomo while I was still a researcher, that really helped with all of the different units.
In addition to being practical calculators, they're amazing higher-order visualization tools.
http://www.projectrho.com/nomogram/ has more info on how to create them in the context of tabletop wargames.
