Archimedean compass

The first thing to thank the people of Twitter that has helped me in the translation of the title Trammel of Archimedes, which in the end has remained as Archimedean Compass. We have shuffled «Archimedean trammel» and another approach «Archimedean Lattice».

Thank you very much to @February 1, @sophocles, @ V4nhel and the one who has found the translation  @ScienceKanija

So let's see what we can do

How to make a homemade Heron fountain

We have seen Clepsydras, Eolipilla or Aeolus of Heron, but we had not yet seen the Heron's Fountain which is a hydraulic machine created by Heron of Alexandria (XNUMXst century physicist, mathematician and engineer) An all-time classic of the fluid dynamics.

The oldest version, that of Heron, was as follows.

how to make a heron fountainThe operation is very simple.

The water is falling from A to C (filled with air and airtight) and pushes the air in C towards B (filled with water), which pushes the water towards A.

Well in the image we have a series of valves that are useful to us to initialize our process, although as you will see it can be done much more at home.

According to the picture. Initially we have the three valves closed and we add water in A. We open V2 and tank B will be filled and opening V3 will bring it to atmospheric pressure. We close the two valves and open V1 for the source to start working.


Binary adding machine

By chance I came across some videos about a Binary marble adding machine o Binary adding machine with marbles

I explain how it works, although it looks very good in the two videos.
