I'm currently sitting in a combo bar/cafe/laundromat in St Petersburg drinking vodka and waiting for the dryer while the schematic is on my PC in Adelaide. I won't be home 'til October 3 and will have well over 100 rolls to process when I get there, so don't expect to see the schematic until at least 4-5 weeks from now. When posted (along with the additional rotary encoder source), it will be GPL of course. It may well have issues too but nothing that should be insurmountable.
If you're impatient, you can build it on a breadboard with no additional components and using the pin definitions in the source currently on my website.
I'm gonna go shoot some grubby decrepit buildings now; I think the street lights are nearly on.
