Step 9:  Add the DC adaptor jack.

Step 10:  Add the inductor.  The halo inductor gets its name from the halo shaped clamp

that holds the core together.  Older versions of the kit may come with a 5 pin inductor.

You would orientate this inductor by inserting the 5th  halo  pin into the inductor eyelet

that is off set.  More recent versions of the kit will come with an 8 pin inductor that has
two u-shaped notches in the base.  Orientate the inductor by lining up the two u-shaped

notches with the layout on the PCB.  Inductors are not polarized so it can go in either way

as long as the shapes are lined up.
