Thanks ExiTeD! not yet the final version, I'm working in the fourth model and a new way to enter the numbers. The model is indeed bigger than the previous one because of keys and tilted visor, so I opted no to make the lego basic box. I've just watched your counter! We've come to the same solutions ...

Hi there mes amis,

here is my third generation Pascaline, now key-driven:



This is an intermediate step towards a calculator similar to an arithmometer.

Hi there,

here it is my new model of the Pascaline calculator:

yes, I will, in fact I've been doing some modifications to accommodate new capabilities and the mechanism shrunk!

the cheese slope is currently the final version, I was inspired by seeing it used in lego clock escapements of youtube user KEvronista I tried 3 solutions before, for both the 2 pawl seen on video: 8 teeth gear https://lh6.googleusercontent.com/-DJOXW0fDI0A/UVziBQZwWRI/AAAAAAAABTU/KQsVi-...

there is no limit for digit positions (original and this lego replica): it can have a hundred positions and it would work just fine, it's like a falling row of dominoes. this the geniality of the Pascaline, a more simple design, like those found in odometers or eletric/water meters are restricted to...

You actually get 10 units on each cylinder with a 20t where a cheesy slope go accross 2 teeth with each move, right ?

exactly, to work with base 10, 1 teeth in each move and you get a base 20 calculator, in fact some Pascalines combined base 10, base 12 and base 20

Bonjour, mes amis after more than a year in which I announced, at my presentation in this forum, that I intended to build a lego version of the mechanical calculator Pascaline, here it is, fully functional! it cost me a lot of time and effort, the centerpiece of the mechanism, the sautoir had more t...

all right, thanks. These language issues apply when you are searching at google: I read a lot about the pascaline at wikipedia (in english) and tried a lot to find an animation showing the mechanism in motion, but for no avail. So after a while I started searching in french 'mécanisme pascaline', (...

Bonjour, je m'appelle Thiago, j'ai 29 ans et je vis à Brasília, au Brésil. Je monte Lego projets il y a longtemps et j'ai des ensembles Basic, Technic et une Mindstorms NXT. Il y a quelques semaines j'ai commencé à m'intéresser à reproduire la calculatrice méchanique de Blaise Pascal (la Pascaline) ...
