A couple of weeks ago, I reported that an engineer, David Brown, was developing a replica of Raymond Scott's sequencer invention, The Circle Machine. Mr. Brown reports progress:
I mounted the base plate on a panel along with the 16 lamp rheostats and three control jacks. I built a separate desktop wood enclosure with an external power supply. I removed three of the vanes and the counterbalance weights to lighten the armature. This was rather a fun project and my first using a stepper motor. I built it for fun since I thought it would be visually interesting. I didn't intend for this to be a precision sequencer nor a faithful recreation of the Raymond Scott Circle Machine. However I am pleased with the results as it works well to generate interesting sequences and is fun to watch.
