I've completely cleaned and lubed the drive unit of the Perpetuum-Ebner. All old grease and oil has been removed with isopropyl alcohol (we call it isopropanol down here).

All parts that needed some grease or oil have been serviced. The table is spinning very smoothly at my desk right now,

powered by a motor from an old video recorder.

With that in place, it's now time to start working on the motor control. She's going to be driven by the Infineon DC Motor Control Shield for Arduino.

I've given the shield a make-over to make it stack better on top of the Arduino, and to get it fitted inside the table.

The revamped shield has stacking headers, and the (very nice Vishay) cap has been replaced by one that doesn't take that much vertical real estate.

I've fitted screws with a very flat head to avoid that they contact the connectors of the Arduino UNO.

 

With all these things in place I can start with the first Enchanted electronics.

The rotation of a 60 year old appliance is going to be controlled by that Infineon shield and the new millennium's Arduino.

 

Pre-work

 

Here is the story about my prototype of the motor control concept:
