| Hubert - Thanks for the positive feed back. I was not even sure it would work, the servos are lo cost cheepees. They have a small thermal drift that a better servo would not have but other than that they rock. As my younger friends say. I should do another video with the tempo cranked up. It's fun to hear Marry had a little lamb played it just a few seconds of time. - Dave |

Hi Dave
watched this on youtube and tried to leave comment but it seems i have some YT account problems.
thanks for sharing and the video. it sounds beautiful and it looks amazing. Do you plan to release the code and project details? while i do not plan to make an RF version, i do would like to build one. controlled by rs-232 or stand alone.

Not at this time. The code is a rough first draft. I may share it when it's somewhat improved.
In the mean time here is an example of fast play. I hope it make you smile. http://www.youtube.com/watch?v=KWB-L06G7rA |

Like a record breaking Minute Waltz in 3 seconds.
Very astonished that it works that fast.
Digital servos against all believes are not noticeably faster at max., maybe a few milliseconds if you look at the datasheets.
The feedback pots are usually more of a problem than anything else when temp. changes.
This is phantastic.
The BASCOM MUSIC MAN.
Keep the good work up.

Indeed amusing . I hope to see the project in the future. maybe an idea to place the xylophone metal plates in a circle around the servo.

Hello Dave
Ever thought about tubular bells! Also would make a great door bell.
Regards Paul |

Mark - I like that idea. It could have many more notes that way.

Paul - No, I just used what was at hand. There are so many possibility. This project was started as a door bell and mail box bell. It can play different tunes for different events. That's why the wireless bit is in there.
Thanks for the ideas,
Dave |

Another idea! Put it inside a plush toy then you could have a xylophone playing dog for example. Maybe you have just invented your new product
