    Mouse encoder signals don't give a forward and a reverse. There are just two lines that pulse when the encoder sees light or dark. Direction is determined by which of the two signal lines occurs first when rotating.

    USB volume knob

    I was recently experimenting with mouse rotary encoder too. Made rough sample:


    The knob made of VHS head.



    There is a program called autohotkey. It alows to map hotkeys to wheelUP/DOWN, buttons.

    I like the look and the smoothness would be great. How do you have AutoHotkey setup? (post your script here) I'm using it already but want to know how to do THIS.

    Hi. was'nt playing alot with autohotkeys. what about someting like that
    wheelUP::F11
    wheelDOWN:F12
    Lbutton+wheelUP::(assign for scrool up)
    Lbutton+whelDOWN::(assign for scrool down)
    Rbutton+wheelUP::(assign zoom in)
    Rbutton+wheelDOWN::(assign zoom out)
    ???
    I actualy meade hotkeys just for volume.
    i wander if u can buy those encoders in shop separatly.

    That would be the best alternative but I'm not sure how to go about it. I'm using a touch screen so I can't use the left mouse button can I? If I connect a push-stay on switch to the right button it only gives 2 options.
    Thanks for the suggestion tho agniusm.

    I would say that if you remap your mouse buttons they will not acts as mouse buttons anymore. Give it a o and see what happens. Cheers

    Thanks Jimmy.
    I've been hacking apart my dash and plan on doing this method too for volume control however I find a slight fault with your wording and I don't want it to cause problems for others.

    Instead of saying "GND" I would use the word "Common". The reason I say this is that I checked a PS/2 mouse and found the what you ahve label "GND" actually is reading 5V with a multimeter. If someone were to hook this up to GND you might kill your USB ports or PS/2 connection.
