Thread: Home made volume knob

So i thought i'd share what i made, so someone else could try as well.
i saw this mod on hackaday a while ago, and i decided to do it.
my setup, i hid the head unit, and i still prefer an analog volume changer, so this mod is perfect for me.

Required materials:
1 x scroll mouse: preferably the old ones without optical, because they use the analog scroll as suppose to the optical ones in the newer ones.
1 x volume knob
1 x solder gun

Steps:
1) Open up the mouse, and you'll see the scroller right away, it should be a 3 legged device. (now if you had one of those newer ones, that uses optical sensor instead, then u'll need to find a volume encoder from older units like car headunit, old home amplifier and desolder them, and they can be soldered right onto the board with the 3 solder spots. This is what i did, because i didnt have one with analog scroller)
2) desolder the device and connect it to 3 long wires.
3) mount it wherever you like
4) Throw on the nicest volume knob u can find around the house.
4) wolla
