Wndsn Telemeter Toolmaking

Engravings, accuracy, and precision.

Wndsn Telemeters are handmade and manufactured in the spirit of astronomical instruments of the age of discovery, built by the likes of Tycho Brahe, Johannes Kepler, Galileo Galilei, and Gemma Frisius.


The Wndsn maker's mark proudly adorns the device; Wndsn fecit - "Wndsn made it". Fecit: commonly inscribed on scientific instruments etc., in the renaissance, along with the name of the maker or designer.

The scales are precision-cut into 2mm thick rigid metal and the whole device is made in Germany.

Scientific instructions in the spirit of the engravings sent with the voyager space probe are engraved and supplemented by a printed how-to.
