Mission Impossibe Puzzle Box with PicAxe

This is my second ever Picaxe project. Shoot, it's my second ever electronic circuit to design and build myself.

Halfway through this project, while exploring the "tune" command in the Picaxe programming language I came up with an idea for a modification to a puzzle box I had. At first I just wanted to make a circuit that played different songs using the monophonic ringtone playing feature of the Picaxe. When I chose the puzzle box as my project box I decided to up the ante and make it a game.

When the puzzle box is tilted or jostled the box will begin playing the "Mission Impossible" theme song at normal speed. It will repeat four times increasing in speed with each iteration. After the last time the box will play a descending white noise sound (like "pshhhhhhhheeeeeeeeeeeeeeeeeeeewwwwwwwwwbbbooooooooaaaaaaahgurgglegurglegurgle" GAME OVER!) These sounds will repeat until someone successfully opens the box and "defuses" the game.

If there's any interest, I'll make a video.

Updated design, pictures and program coming soon.
