Performance coming up. Arcade board assembly!

Hey.
We have a performance with danceOmatic on the 28.-29.-30. June, for ViaThea in Görlitz - Germany. Therefore I'm preparing as much as I can, since it is almost a year since our last performance in Denmark.
Here a little peak behind the arcade board.

For now the solution is the buttons & switches are connected to a hardware device called IPAC2. This is then connected to a laptop.

The IPAC2 convert the button signals into keyboard values through this software

Quite simple actually.
In the future I want it to run directly connected to a Raspberry Pi though.
