There is a 12 volt high torque motor between 3 to 30 RPM currently operated by manual dial. Now we need to save sequences of speed changes to music using a DMX program. 255 increments of speed. The Arduino hardware and DMX software should be sorted by the same person/group. We want to actually meet and work on the physical job together around London/Bishops Stortford/Cambridge etc. There is a modest budget. Visit Really Psychedelic Sunshine on Facebook to understand the application.
See PM. Not local, but can help
