[sdiy] Question how to improve rotary encoder feel

[Scott Gravenhorst]

Just spit-ballin' here...

There are optical encoders that are used to detect motor speed and/or
shaft angular position.  Obviously, these are designed to be connected
mechanically to a motor, but I see no reason a person with mechanical
skills couldn't adapt one to use with a knob.  They have no detents, so
they rotate freely and smoothly, even to the point of being able to
spin.  Maybe a flywheel could be added to allow more spinning with a
given amount of force.  I've no idea what these would cost tho, nor the
resolution of counts per revolution.  The only reason I know about
these is from reading about them in a dsPIC...MC (motor control) chip
datasheet.  These chips have QEI peripherals in them to automatically
count the revolutions.
