Elisen Lebkuchen - Musicbox - non stop sound!

In Germany they bake these wonderful "Elisen Lebkuchen". It's a special from the city of Nuernberg. They also sell these cookies in music boxes as agift ( http://www.lebkuchen-markt.de/ , http://www.manufactum.de/Produkt/193510/779545/ElisenlebkuchenSortiment.html ).

After winding up a spring the music i beeing played. It costs some energy to wind up the "music player", so that you have to eat some Lebkuchen ... ;-)
After eating all the Lebkuchen, how can you manage to hear the nice music while beeing so weak?

Just put a motor in and keep it running, powered by battery. This instructable shows you how ...

Step 1 Dismantling

Looking inside the box the music mechanism can be seen. Take it out of the box.
There is a black plastic housing that contains the spring and some gear wheels. It needs to be removed because we want to take out the spring and get rid of some other unused parts.

The housing is held by some bolts. Use a dremel tool to remove the top of them. Now carefully pull of the plastic housing. Try not to break it because you need it later. Be very careful with the cylinder containg the music. After the housing is taken off, pull the spring out.
