Step 13Build the user control panel
for sliders, you have to make slots which is a bit tricky. here i used a pre-fab electrical junction box cover which had an appropriate sized cutout already. then i just needed to mount the sliders neatly in the cutout. i spaced the sliders apart evenly using some hex-nuts, and then put them on top of a rigid substrate (a re-cycled chunk of circuit board).
after lining everything up, i poured on some hot-melt glue (make SURE not to get any inside the sliders!). after the sliders were well attached to the rigid substrate, i aligned the substrate against the metal cover and glued them together.
we'll make the front pretty later.
