Xylophone Robot

This is simple 3Dp beginner project for every one that has access to 3D printer.
Additional what you need is:

• 2x servo
• Arduino/Raspberry Pi or any other programmable platform to control servo
• xylophone or similar instrument (you can also improvise ;) )

Grab files from http://www.thingiverse.com/thing:1379539

If you have Servo "hex tronik hx12k" or other same dimensions you can directly print
file "hex_tronik_hx12k.stl"

For other servos insert your dimensions in to servo1.scad and generate stl file using OpenScad

If you have Servo "hex tronik hx12k" or other same dimensions you can directly print file "hex_tronik_hx12k_servo_top.stl"

For other servos insert your dimensions in to "servo2.scad" and generate stl file using OpenScad

All printed?

Now you only need 8 screws to screw the top and bottom servo,
and press fit the top servo to bottom servos servo horn.

To reduce stress to the servo, the "drumstick" is held only by rubber

If your base is to light drill some hole and glue in some heavy material
or use some tape.

Done.

Connect servos to programmable platform of you choice and program a song that you like.

Arduino:

• Scratch + Arduino

• Arduino servo control tutorials

Raspberry Pi

Here a simple Arduino test - full octave and short Slovenian folklore song "Čuk se je oženil"
