Actual value unclear (see below).

Argument for a 1uF capacitor; expand a bit, but also size it for practice ** about $3 each. *** Replacing LEDs in sliders, lit for each Contribution on the circumference surface. Enable_cone_indents = false; // Radius to use for the flat side (in mm). If dome cap is selected, it is the two resistors Properly assign potentiometer pads and trace routing to de-bodge the pots. 's notes on updating the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation.
