I've build this to make people in my office happy :)
The idea is to built something like this "days without accident" panels. Each time somebody will push the button, the counter resets and Last Xmas will play.
Step 1: The Ikea Frame RIBBA
I took one of this IKEA 3D Frames and took it apart
A 4mm Plexiglas panel and a DinA4 self adhesive paper,with printed Text on it
I used the toner thermotransfer methode to make the PCB's
I made 2 PCB's. One for the counter electronic with the atmega328 CPU, and one for the MP3
module WTV020-SD-16P and the amplifier
The counter increments each 24h.
A piece of red plastic foil for the display and a piece of Mosquito cover for the speaker (with a few test holes :) )
All the stuff fixed inside
The counter reset button
It's installed for 1 year now and it's a pain !!!
25 Days... The highest number ever reached until now :)
