Well, The schematic is in Autocad DWG and its kind of ad-hoc, so I hesitate
to tarnish my rep by sending this nasty thing out...  but if you can deal
with DWG or DXF I'll be glad to Email it to ya!  Yeah, that sensor problem
was a different system which I plan to optically isolate, this system is
interfaced to a device which holds the I/O line high via a separate power
supply (in the PC)  and that always puts a few extra millivolts on my
power-off.  Should I perhaps use a diode/relay/analog switch to turn off
the I/O when power is off?  I hope the optical isolation helps with the
other problem... mabye thats what I could do here as well.... But I DO need
something extra, because even with everything unplugged, the system STILL
holds enough voltage in the filter caps to screw it up even over-night!
