The latest thing I've done with Ivan occurred during my recent absence from Hackaday. I added rubber bumpers to Ivan's spinner and put one inch diameter jingle bells in it. I tried from one to thirty jingle bells and found that four was the ideal number.

For a while I had the beginnings of a jingle bell song going but this and that and some blown chips later, I just set it at max rotary velocity for the sake of demonstration, lol.

I van has a greater purpose in life but for now he is a Jingle Machine!
