Rickroll Box

Description

Recently my kids started to rickroll me, so I've build this player to take revenge...

It's a simple box with a power limit switch on the bottom and when you lift it, it will start playing "Never gonna give you up".

The DFPlayer can be fully controlled via serial interface or simply started by pulling the IO_1 pin to ground very shortly. I've opted for the latter and used a attiny85 to kind of emulate this button press after power up.

BOM:
- DFPlayer mp3 module
- attiny85
- Limit switch (20x6mm)
- Small speaker
- 3x AAA batteries
