Santa Strumming on the Rooftop

Tell us the story of your project: 

I've used this dollhouse as a base for many projects now.  Each window has a neopixel which is controlled by an Arduino Uno.  I leave that in the dollhouse all year so I can easily change the color of the candles in the windows.  An Arduino Mega with MP3 module controlls Santa and plays "We Wish you a Merry Christmas" when the button on the rooftop is pressed.  Santa has two servos one in his neck and one on his arm that make it look like he is playing along.  Santa's reindeer has a wreath of leds that cycle through as the song is played.  

This is a project that I keep modifying year after year to make it more complex as my skills grow,  

How-to: 
My husband helped me by 3D printing a long arm for Santa's arm.  He also printed an elliptical base for the neck servo.  After decapitatiing Santa we cut a hole in his back for the wires from the servo and then filled his neck region with body filler.  We then submerged the servo.  For the arm we placed a wooden block on the wooden base where Santa sat and glued the servo to the top of the block.   The button was set-up from a prior project.  I then programmed the servos to move as the song played so it looks like Santa is strumming the guitar wishing visitors to our home a Merry Christmas and a Happy New Year.

Teaser: 
The dollhouse that my grandfather made me over 40 years ago now has a Santa on the rooftop who plays the guitar along with Weezer's "We Wish you a Merry Christmas and a Happy New Year."
Aha! moment: 
I figured out how to get the servos back to a neutral position after moving for the song. Before I did this there was a buzzing sound of the servos struggling to stay in the somewhat engaged position I had left them in after the song.
Uh-oh! moment: 
At first I had a servo in Santa's leg but it was just too much for the servo to lift Santa's leg to tap along with the song.
