A pinwheel calculator emulated by Arduino
— December 16th, 2013
The Odhner Arithmometer was a very popular pinwheel calculator invented in Russia in 19th century by a Swedish immigrant called W. T. Odhner. Like most of pinwheel calculators, it worked with an engine formed by a set of linked wheels which could perform the four basic mathematical operations within a machine of reduced size.
Diego Cueva worked on a diy emulator called Duimometer, made with Arduino UNO. See how it works in the video below and look at the sketch here.

Most interesting – I own an Odhner Arithmometer in reasonable working order (needs a little cleaning and oiling) Is the schematic for the Duimomemter available?
