SUPER ELEGANT right now, lol..
So it controls a presto 6n. TT speed, lathe motion, and head. I'm using a motor that provides a hall effect feedback for the turntable, this info is processed by a P.I.D. control loop, and the drive is timed via the PID feedback, Real Time Clock, and a Quartz Crystal. This means it's stable as fuck, and will fight drag.
The whole system right now uses 2 20mhz Stamps, one for the lathe and one for the tt drive. As of yet I only have one pitch programmed, and have not started work on the variable pitch aspect. I'm waiting for some chips to arrive so i can learn more about AD/DA converter chips. Once they arrive, i will start work on the variable pitch.
The head is controlled via a servo, and the lathe is controlled via a stepper motor and a h-bridge. Once i clean up the lathe I'll post some pictures, need to find a better camera too..
Lots of testing tweaking to continue..
The final look is planned to be 505mm x 3u.. it's not quite a 19" rack mount, but is the same size as the presto.. I'm making mine vertical, to be place on the left side of the unit. Anodized Aluminum panel, aluminum buttons and knobs, not the knobs pictured..
sorry the pics suck, i used a web cam..
