 # Mechanical Computer
 
-Mechanical computer (simple ones also being called *mechanical [calculators](calculator.md)*) is a [computer](computer.md) that uses mechanical components (e.g. levers, marbles, gears, strings, even fluids ...) to perform computation (both [digital](digital.md) and [analog](analog.md)). Not all non-[electronic](electronic.md) computers are mechanical, there are still other types too -- e.g. computers working with [light](light.md), biological, [quantum](quantum.md), [pen and paper](pen_and_paper.md) computers etc. Sometimes it's unclear what counts as a mechanical computer vs a mere calculator, an automaton or mere instrument -- here we will consider the term in a very wide sense. Mechanical computers used to be used in the [past](history.md), mainly before the development of [vacuum tubes](vacuum_tube.md) and [transistors](transistor.md) that opened the door for much more powerful computers. However some still exist today, though nowadays they are usually intended to be educational toys, they are of interest to many (including [us](lrs.md)) as they offer simplicity (independence of [electricity](electricity.md) and highly complex components such as transistors and microchips) and therefore [freedom](freedom.md). They may also offer help after the [collapse](collapse.md). While nowadays it is possible to build a simple electronic computer at home, it's only thanks to being able to buy highly complex parts at the store, i.e. still being dependent on [corporations](corporation.md); in a desert one can much more easily build a mechanical computer than electronic one. Mechanical computers are very cool.

 { Britannica 11th edition has a truly amazing article on mechanical computers under the term *Calculating Machines*: https://en.wikisource.org/wiki/1911_Encyclop%C3%A6dia_Britannica/Calculating_Machines.
