another hypothetical design
most of us know about the digital potentiometer and its rotary encoder so it has the same or similar functionality to an analog mechanical potentiometer
however the digital potentiometer, has full digital control over its knob setting even remotely. regardless of the mechanical knob setting.
however here is an idea I have had for some yrs now. what if a rotary encoder knob could show digital position markings!
in some way display the digital value of the digital potentiometer setting on the mechanical rotary encoder knob its self.
using individual LED ring design or a 2 digit 7 segment mini LED display inside the face of the mechanical knob
inside a custom concentric knob.
shaft dimensions or shaft type maybe a concentric design.
a word about mechanical knob actuators,
this post is Not about using DC motors to move mechanical potentiometers by friction clutch.
so a potentiometer knob can be moved without forcing a mechanical actuator.
the hypothetical design idea here is about rotary encoder body and rotary knob design.
electronic component design. in the hope that a manufacturer will take up the design shown here.
or improvements in a new better design. any suggestions? or knob design Blender art or
know of a rotary knob manufacturer already making a
component design like this?. if so, just kindly disregard this posting. and please add a link to it.
here is my hypothetical design
its a panel mount coaxial knob of a custom concentric design.
that is both a display and rotary knob in one unit.
the parts of a hypothetical rotary encoder & concentric display knob design.
only needs one 3/8" mounting hole 6.75mm diameter. Includes nuts and dress washers.
the display bezel design. has the individual LED ring in the bezel outside the shaft bushing behind the knob.
using the same panel mount .
here are two working examples of the rotary encoder showing a digital position design.
both are rudimentary in concentric knob design. however show some circuit design functionality we are seeking here.
just in a more compact form factor then thay have made, so the electronics can fit inside the knob.
this is something only by skilled manufacturers with custom made flexible pcb material
A rotary encoder with LED display
https://www.waitingforfriday.com/?p=381The project is based around a 24 position rotary encoder, 16 LEDs arranged in a circle around the encoder,
an A6276 16 LED serial driver IC and the PIC182550 microcontroller.
