The Raspberry Pi lacks a decent power ON/OFF button. With a handful of cheap components a ATX style power-switch can be build.
Schematics
Main parts are a PIC microcontroller, a 5V relay, a push button and a LED.

They asked me “We like to add special noises to the machine, is that possible?”. Sure, no problem. So I hooked up an Arduino board with a MP3 shield and started programming.
