The circuit board

Ensure you do have the right driller size.
My first try (the middle one) was to small for the arcade buttons, took me two hours to grind it to the correct size.

Just to check if everything fits in

RFID Reader mounted with the “stick tape”
Buttons from below (Missed the shrinking tube)

Flashing the nano and get everything connected.
Battery pack is missing on the picture, it is also mounted with the stick tape.
“Someone” can shake the box and nothing should happen.

Ready to be used
Advice use the RFID chip for the admin functions.
