hidden detail dotted lines, and the cut tracks are also shown as shaded. his is for ease of orien-
tation, although you won't actually see this when you look at the board for real. he solid lines
are tinned copper links; these can be the scrap from cutting the legs of components or simply
stripped-back solid core wire. he foam pads can be glued on using impact adhesive; you can cut
them out from some packing material. Finally, a strip of 8-way ribbon cable is soldered to the
board to make the connections, and spots of hot melt glue make sure that the wires do not foul
the switches or pads. A photograph of this is shown in Figure 14-7; note that it is a photograph
of the antiparallel LED version of the joystick so it corresponds to Figure 14-5. At this point
you should test the board as described later in the subsection “Joystick Testing”. In that way
you can correct any mistakes before too much gluing is done. However, I will irst continue the
building narrative as the inished article needs testing as well.
