How to use this Volume knop

**zeecue** · 09-22-2008, 04:15 PM

Hi

I have got this knop, wich has a push button and a rotating function.

I know how to wire up the push button up to my keyboard controller.
But how do i wire the rotating function op to my keyboard controller?
The controller has 2 wires that need to be shorted when the button is pressed, just like a normal keyboard.

Heres a picture of the undeside:

Edit, can it be connected to a mouse instead, like the ScollVolume things?
I just want the easiest and cheapest way.

Best Regards
Morten Jensen

Yes, you can connect it to the scrool wheel on your mouse. No problem :-)

It'll depend on the kind of encoder that the mouse uses. Some use more pins than others.

It might work with this USB gizmo: http://www.madhacker.org/usb_hid_keys.htm

This one is similar but also does LCD: http://forums.bit-tech.net/showthread.php?t=115461uses

The scroll wheel inside a mouse has 3 legs just like your encoder. All you have to do is desolder the scroll wheel and replace it with wires from your encoder but make sure you take off any resistors or diodes connected to the encoder. You can also hook the push button of the encoder to the middle click of the mouse, that way the encoder can perform 5 different functions using the girder mouse plug-in. Let me know if you need more help.

Hi Kalt.

What wires on the knob should i wire to the mouse encoder?
And what if i have 2 knobs, one i would use for volume, and one for scolling just like a ordinary mouse?
The push function on the knob, will be used for a power button, and the other as a enter or mouse click.

why not just go with a lilliput rather than an off brand?
i just bought my lilliput off ebay for $175 shipped and for $25 more what youd pay for the no name, mp3care store sells them for $300
