It sounds alot like what I want to make, at least for once I will have a head start on one of my projects.
It got trashed / recycled. I'll see if I can upload the schematic when I get a chance, assuming I still have it somewhere that is. The approach of using PWM over a DAC I found to be just as good in terms of performance, with the obvious upside of being far electrically simpler, cheaper, space conservative, requiring only 1 pin.
