o2 sensor

[Frederic Breitwieser]

> Got mine mounted on steering column, pretty lights flashing back & forth, and actually *useful* - replaced my O2 sensor recently, flash rate was MUCH faster than w/ the old one, so @ least you can tell when its going.  No real use for tuning, though, too coarse resolution - need a scan tool to do that well.

Though you can cascade two, three, or four for more resolution if you
must.  I'd offer a schematic but its been ages...  I think Radio
Shack's "Electronics Experimenter" book (orange cover) has a cascaded
3914 schematic in there.
