Digital Configurable Analog Computer RG21
After the good experiences with the RG14-mini, the new analog computer RG21 is on its way.

The documentation of the current version is not yet fixed; currently, three documents are provided (in German, drop me a line if you are interested in a translation):
All designs can be freely used, if there is interest.
