Alan's Schickard Calculator page

My home built Schickard Calculator:

As with most of my projects, it was a sudden and ill thought through decision to do it and rather than study or
plan first what I intend to do I just jump in and make a start, so this is not historically correct etc. but is
loosly based on information kindly provided by THIS PAGE
and adapted to be easy/cheap for me to build using materials easily available (mostly MDF) and using my home made
CNC router.

I first learned of the existence of the Schickard Calculator on 10th November and on 29th I had finished building my
own which has to be some kind of record? ;-)
