Answers to key planning questions¶
What will it do?¶
The goal of the project is make simply score board with increadable features to make it very useful. there are two features : the first feature is to display scroring during a play and the one else is to display the substitution.
Who has done what beforehand?¶
Fo my case the inspiration of this project comes from my prof who give instruction or indiation about how the will work thus the ideas are came by this way to make the project.
Anyway I can mentioned Stramatel enterprise who made stramatel multifunctionnal scoreboard. we had one and I use it and it was somewhat fascinating, it was good experience thus I try to do smething like this.
What will you design?¶
I will design all aspect of the project namely the scoreboard(the frame) and the external module.
the different aspects refer to
1) The box / frame of the device and the box of external module
2) The the main circuit baord and the screen module circuit board and one else for the external sensor module.
3) Design Smartphone app within bluetooth communication.
What materials and components will be used?¶
1) The MDF for the frame
2) 3D print filament -PLA
3) The P10 module LED matrix
3) Electronic components and PCB boards
Where will come from? / How much will they cost?¶
All are either provided by lab.
Below is a full BOM to give the cost of the project
