As more automation gets integrated into ornamental turning, it is being delivered by microcontrollers like the Teensy from PJRC.
The Teensy grew from the work done by Italian professors to help students get better at developing control systems. They called this prototyping system the Arduino, and it has been greatly adopted by the maker community.
Fun Fact: The name 'Arduino' comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet.
Disclaimer: eMail comments to me at OTBookOfKnowledge @ Gmail.com. The process of woodturning involves the use of tools, machinery and materials which could cause injury or be a health hazard unless proper precautions are taken, including the wearing of appropriate protective equipment.
