Darrel you are amazing!
I tried this out yesterday and it exactly what I'm looking for ( I am making a fuel consumption / complex odometer for my ancient Land Rover) and as I can't see close up without glasses, but have perfect long distance vision, a normal LCD display on the dashboard is quite useless and I had been considering large 7 seg display, but this is beautiful! Thanks a million.

PS: any tips on saving a counter on power-down? I was going to have the PIC running off big electrolytic for long power down delay, and then have one port sensing the instant loss of the (voltage divided) 12v ignition and then quickly write to EEProm, but would it be clever to use a brown out flag or something like that?
