PLATE is cut off the Printed Circuit Board leaving 3 areas for the
5 projects as shown below:
The HIGH GAIN AMPLIFIER is built on the first section, then two more
parts are added to make the LED Flasher on this section. The FLIP FLOP
is built on the second section. The Fibre Optic Display uses the
circuit from the first section and the 7x10 matrix board included in
the kit. The fifth project SIMPLE SIREN, is built on the third
