[sdiy] Analog division

[David Moylan]

You canput a multiplier in the feedback loop of an opAmp.  Saw that used 
by Mark Smart, don't know if he's a lister:

Hunt around for schematics there.

Also i've been looking into using the AD633 but hot damn they're expensive. Any pointers to a fairly accurate (not exceedingly so) division-circuit?
