Music box
Less than a year after my comment that would be nice to make a music box with a ballerina in a publication «Light and music favorite gift with their own hands» .
I apologize in advance for the quality of photos and videos.
Electronics and firmware took from topic "Light and music favorite gift with their own hands." Music left "Tenderness" from to. F. "Three Poplars at Plyushchikha" she bribed me with his tenderness, yes, I confess, I did not find suitable.
The power button and the engine sound module total and only for a short, because of what had slightly modified scheme:
1. In order not to change the firmware, I put on a pin on the device start ringing resistor and a capacitor, simulating a click.
2. Engine and sound module powered from different sources sinking, which is interrupted by a button, so added a pair of diodes for each load.
Mechanics I was kindly helped develop laser-cut and workmates.
The only difficulty was set in the center of the engine to the gear does not have a snack.
It's all glued parts except gear:
Bottom view of the assembly.
Herself a ballerina printed on 3D-printer.
