I have a magnet inducing up to 50mv in a coil, and
want to convert the signal to drive a servo. I've
looked up V/F conversion, VCO and the like, but
just don't know where to begin. I know I may need
to amplify the signal to begin with because most V/F
chips need more voltage than my coil supllies,
but most of those chips also specify high frequencies
(so I thought maybe if I could simply control a 555
output I would do better, re the servo's 1-2ms
pulse width for the control signal). Can anybody
point me in the correct direction for the circuitry I
need to build, or a means of simply controlling
the 555's output <I would set it at 1.5ms and have
my -50mv to +50mv signal alter the 555 between 1
and 2 ms> ???
