Battery, Chips, Voila!

Once everything is hooked up, unscrew the circuit board and solder the battery clip leads to the board.  This is done at this final stage as you will have to feed the battery clip leads through one of the holes in the battery compartment.  The Red battery clip lead goes to the V+ pad on the circuit board and the Black battery clip lead goes to the V- pad.

Now comes the part you have been longing for!  Insert the IC's into their sockets making sure that the notch is oriented in the correct direction.  GROUND YOURSELF FIRST so that you are not carrying any static electricity.  Static kills chips!

Sometimes you have to bend the legs in slightly to get them to line up.  The easiest way is to gently push one row of the chips legs down sideways on a hard surface.

Before you put the two halves of the case together you need to protect the back of the circuit board from the terminals on the back of the piezo horn.  Take the non-slip matting and fold it so that it is twice as thick.  Now scotch tape (gaffer tape) it over the back of the piezo horn so that it covers the terminals  This should stop the circuit board and the piezo horn making electrical contact while providing cushioning to hold the circuit board against the back of the case.

Finally put the two halves of the case together making sure that you have not trapped any of the wires (watch out for the floating LED cathode lead) and screw it together.
