Wolf's Collection of Slide Rule Replicas


Slide rules are not manufactured anymore. The ones, which still exist, will eventually deteriorate with time. Here you will find a collection of some of the most prominent models carefully hand-crafted and simulated (or emulated) in JavaScript.

It is a Slide Rule Simulator or Emulator

All the scales are programmatically drawn based on reverse engineered mathematical equations. As such, no images are used for visualisation (only some decorations). And this is why those simulations are of the highest quality. This is also why the word "replica" is quite appropriate for those simulations.
