Introduction



What this software does?

     This software create a Electrical Installation of buildings project with a minimum interference by the user. You just need to input the room's dimension and the specifc power plugs, such as washing machines, motors. The software will make all the calculations such as the number and power of general power plugs for each room and each type of rooms, light power, cable and conduit sizing following the IEC rules for Electrical Installations of Buildings, which is, in Brazil, is ruled by NRB5410 from ABNT (Brazilian Technical Standart Association). Furthermore, a list of materials needed is generated based on a list of products already available in the Database, follwed by the budget.



A brief process history

     I started this project, after finishing my third Nanodegree in Data Science, looking for some application for the knowledge and skills I have learned, using my background in Electrical enginner and programming skills. In that time I was studing Electrical Installation of buildings and I had many difficulties to use the softwares available for that purpose. So, I thought, why not make my own software? And the result is here.

Rolling mean from time between commits

     Once I became more confident using git to version control I started making commits more frequently, and doing so I was wondering how much time I was spending between commits. To check this information I made a Rolling mean graphic with a 50 commits window as you can see in the picture bellow. As I expected, the time between commits can be a good way to check your productivity once your routine and your commit behaviour are stable.
