John,

Is your digital/independant monitoring system a "homebrewed" setup or something available commercially? I ask because I remember picking up (5 years ago?) an issue of one of the electronic hobbyist magazines that had an article on just this sort of setup for the "do-it-yourselfer". When I recently decided to augment the stock warning lights of my van, I tried to find the magazine only to be informed that it had been sent to recycling (by the person who occupies the passenger seat of my Westfalia).

Well, I opted for VDO oil pressure and voltage gauges and they work fine, but I'd be interested in hearing about your setup, i.e, what sending units used?, schematics?, reliablity of setup?, calibration?
