Hi everyone,

I want to present to you My analog cuircuit design to build a rotary encoder system i think very helfull for hobbysts, it's possible to hack many things without using a microcotroller or an arduino, this is my video. enjoy yourself !


And My schematic:

Nice, but I do not see how you make an analog voltage proportional to pulse count.
Have you heard of Selsyn?
Otherwise the simplest rotary angle to voltage converter is a potentiometer. completely analog device.
 

thanks you for your responce, pulses are generated by Transistor T 7 every sycle, my circuit is based on a special design fli-flop system associate to Transistor T7 disigned to timing the lighting of the LED's.

I never heard about selsyn, but i see some information about the system, it's very intresting it's an old technology.

Of cource i know potentiometers, but my system is designed to hack every devise have two buttons to ajust volume or frequency or Rc control without using microcotroller, thank you
 

Hi everyone, this is my assembled circuit board, it works very well.
