DIY: Busy House, 3D printing, woodworking

Down below pictures of the DIY project for my son, wooden house with RaspberryPI 4B 1Gb RAM, with 3CX PBX installed for phone on the wooden house.
A lot of buttons and switches, every button do something, play sound, turn on leds, starts the DC motors.

Simple python script that play sound, turn on lights, turn on DC motors etc, when buttons pressed. If it gets boring you just change the functions of the buttons.
