Step 1 - Preparing the Printed Circuit Board (PCB):
We start by snapping the circuit boards apart. See those little tabs? They have to be
removed too. We find that pressing down at an angle against something hard (no, not
your little brother’s head) will make then pop off, or just use your snips to cut them off.
Don’t forget the small triangle piece, and make sure you’re wearing your eye protection!
See the little grooves left behind by the tabs? You have to use some sandpaper or a file
to smooth these down. Besides making your Herbie look better, it will actually make
assembly easier.

Step 2 - Soldering in the Eyes:
YES, we’re going to jump in with some component soldering. Now is the best time to
install the two photocells. Note there is a proper side - the orientation of the white bar on
the cell needs to match the white bar silkscreened on the printed circuit board (PCB).
