Bar End Brake Light: BEBL

Step 2 Prepare board

Cut the printed circuit board (PCB) into three strips with a Dremel tool as shown.  Viewed from the top side (the side with white markings), the middle section of the board should have 2 holes on the left side of the central rails and 3 holes on the right.  The widest board that my handle bar will accept is ¾ inches.  So, although I would prefer 3 holes on each side of the central rails, there is not enough width to accommodate that.  Measure the inside diameter of your handle bars and cut the middle piece to fit inside, being careful not to mar the copper on the bottom surface.  One of the edge pieces will be the slave board.

The outside pins on the oscillator (Osc1) will be aligned with pins 9 and 11 on the socket but need to connect to pins 9 and 10 on the socket however.  To prevent the unwanted connection, cut a slice out of the copper to isolate pin10 from the other holes (shown in white on the diagram).  With a multimeter, verify that the connection is severed.
