Waterproof Speaker For Better Shower Singing

Step 5 Drill the control holes

Position the circuit board where you'd like it to be and mark off where you'll have to make holes for the control knobs and power button.  Use your glass and tile boring bits for this, and make sure everything will fit nicely.  For my project, I had to make sure the knob holes were just big enough that the knobs would turn freely, and for the switch I had to make sure a hot glue stick would fit through smoothly--more on that later.
