Waterproof Speaker For Better Shower Singing

Step 6 Seal the control knob holes

Your version of this may be different, but for mine I knew the power button could be sealed from the outside, but the "Volume" and "Tone" knobs would need to be sealed somehow, but still turn.  I didn't feel up to rigging some sort of o-ring or gasket system, so I took the easy way out, which may or may not actually hold up in the long run. 

I cut the tips off of two fingers of the rubber gloves and sealed them over holes from the inside.  Once the circuit board is installed, the plastic knobs will fit over the potentiometer knobs with the rubber still in between them.  I left enough rubber so that it would be loose and still turn.  See the pictures below if that was confusing!

If anyone out there has a better idea of how to accomplish this, let me know.  This was the best I could come up with, with just a couple of days left before Christmas.
