IoT featured soccer table

To hold the two LCD displays in place on the table and to avoid the users damaging them we ended up welding our own metal frame to hold it tightly on the end of the table. Furthermore we added a sheet of plastic in between the metal frame and the display inside as a type of display protection.

To ease the later firmware programming of the menu system we decided to design most of the GUI's in Photoshop in the correct resolution (aspect ratio) so we can easily identify the locations of the different objects when we are going to program the menus.

Finally the new football table with logos and black sides has arrived - though arrived in pieces!

So it's time to put together the table and see if we can get it to work as a regular football table at all.

Firmware wise we had to plan the API that the STM32 would be using to connect and communicate with our webserver to save the stats. Thanks to the whiteboard we ended up organizing everything into categories and boxes to get an idea of the use cases.

For the second board design we decided to get rid of the individual RGB color strips (all the same color) so we could get rid of the high current transistor drivers on there. Instead we would be using a WS2801 controller enabled LED strip so we could control all the pixels individually.

A 3D rendering of the final connector board design that hooks up to the Olimex STM32 board can be seen below. The schematic and BOM list can be found as the System Design document in the side.

Before starting on the second version of the football table controller we designed a custom board too and tested it on an old football table implementing some of the same things as described in this project.

Though thanks to the kind donation from Tuborg fonden we could realise the project completely so we decided to do a complete redesign of the board.
