Many of us have Premotec, McLennan etc 230/110v ac syncronous motors driving our TT's. The professional controllers are expensive (and possibly rightly so). So a good (free) flexible controller design with PCB layouts is possibly long over due.
The last good one I saw used PIC controllers and was 10 years ago.
Now we have Aduino boards (and other brands) that are cheap as chips.
Has any one done any design work with these. Seems it will be easy to have a display, controls etc.
Assuming the audio output is fed to a couple of chip amplifiers, should be simple to control frequency (speed) voltage and phase shift, with or without step up transformers.
I would be keen to follow this up (need controller for new TT)
but dont have the nouse to ensure all componets will work together without creating smoke.
I'm sure there will be at lot of interest for this project!
If this is already done could someone point me in the right direction.
