Using Parts as Conductors

WARNING:
Moving parts. Do not touch the
fan or motor during operation.
Note that the color LED (D8) lights,
but the lamp (L1) does not light and
the motor (M1) does not spin.
Electricity is flowing through the lamp
and motor, but not enough to turn
them on. So in this circuit they are
acting like 3-snap wires. You could
replace D8 or L1 with a 3-snap and
the circuit would work the same.
Modify the preceding project by adding the pointer as shown on the left. The paper should be
cut from page #52 and taped high enough on the speaker so the pointer will stick over the fan
with paper. Bend the pointer at a right angle as shown on the left.
Setup:
Cut out the grid with four (4) colors from page #52 and place it under the base as shown
on the left. Each player picks a color (or two colors if only 2 people are playing) and places a
single snap on row G. The purple player in column 1, the blue player in column 2, the green
player in column 3, and the yellow player in column 4. Spin the wheel by closing the press
switch (S2). The first single color wedge that the pointer points to is the first player to start. In
some models you only have three 1-snaps, so use a 2-snap if you have four players
.
The Play:
Each player gets a turn to press the press switch. They release the press switch
and when the pointer points to a wedge, the players that match the colors on the wedge get
to move up one space. If a liner comes up like the one shown on the left then the players on
each side of the line get to move up two (2) spaces. The first player to reach the top row (A)
wins. If two players reach the top row at the same time they must both drop down to row “D”
and play continues.
Turn on the slide switch (S1) and push the press switch
(S2), you hear space war sounds. After a while the
sound may stop, shine light on the phototransistor (Q4)
to make the sound resume.
Cut this shape from page 56
and tape it to the speaker.
