I may be wrong but I was assuming that the electro-mechanical action was some kind of coil and spring assembly. A stepper motor would work as well. I have a microcontroller to drive it so I can configure any control I need.
Does anyone know where I might be able to find the internals for an electric dial gauge such as a automotive tachometer?
I am in need of a ready to use module that can be mounted on a PCB and take a 0-5vdc input.
