Generator - Elenco Electronics SC3DMEG Instruction Manual

Project 114
The clear motor (M4) can also be used to generate electricity,
all that you have to do is turn the shaft. But you have to turn
the shaft very fast to generate enough electricity to do much.

Water Completes the Circuit
Build the circuit as shown, leaving the ends of the red &
black jumper wires unconnected for now. Turn on the slide
switch (S1); the blue LED (D9) should be off.
Place the loose ends of the red & black jumper wires into
a cup of water (but not distilled water), without them
touching each other. The blue LED should be on now,
because water conducts electricity, completing this circuit.
Try dissolving some salt in the water or using different
liquids, and see how the LED brightness changes.
Don't drink any liquids used here.

Generator

Build the circuit as shown; then mount the illusion card holder on
the motor shaft. Wind the string through the mirror holder and then
around the motor shaft about 10 times. Holding the base with one
hand pull the string; the blue LED (D9) lights briefly. Spinning the
motor generates enough voltage to light the LED. Push the press
switch (S2) to rewind the string and try lighting the LED again.
Now move the end of the red jumper wire from base grid location
B3 to D4, to add the blink red LED (D11) to the circuit. When you
pull the string now, LEDs D9 and D11 light briefly.
Project 115
Use the preceding circuit, but place the color2 LED
(D12) across base grid locations B5 & D5 (+ side to D5),
and add a 2-snap across base grid locations D4 & D5.
Move the end of the red jumper wire from base grid
location B3 to B5. Pull the string and all three LEDs
should light.
You Complete the Circuit
Use the preceding circuit, but
instead of placing the red & black
jumper wires in water, touch the
metal part of each with your
fingers, using your body to
complete the circuit. Wet your
fingers to get better electrical
contact.
should be on, but brightness may
vary.
