Project #53
OBJECTIVE: To build the circuit used in a toy laser gun with
flashing laser light and trigger.
When you press the press switch (S2), the integrated circuit (U2)
should start sounding a very loud laser gun sound. The red LED will
flash simulating a burst of laser light. You can shoot long repeating
laser burst, or short zaps by tapping the press switch.

Project #54
OBJECTIVE: To build a circuit using the space war IC to make
exciting sounds.
Build the circuit shown on the left, which uses the Space War
integrated circuit (U3).
Set the slide switch (S1) on and the speaker (SP) makes exciting
sounds. The output of the IC can control lights, speakers, and other
low power devices.
You may replace the speaker with the 2.5V lamp (L1), and the bulb will
flicker. You can also use the LED (D1) in place of the lamp (position it
with the “+” side towards the 6-snap).
