Elenco Circuit Maker Skill Builder 125 - Manual (Page 12)

Up, Up, and Away!
Project #1 Turn on the Light
Project #2
Circuit Maker Skill Builder 125 uses electronic blocks
that snap onto a clear plastic grid to build different
circuits. These blocks have different colors and
numbers on them so that you can easily identify them.
Build the circuit shown on the left by placing all the
parts with a black 1 next to them on the board first.
Then, assemble parts marked with a 2. Install two (2)
“AA” batteries (not included) into the battery holder
(B1) if you have not done so already.
When you turn on the slide switch (S1), electricity
flows from the batteries through the lamp (L1) and
back to the batteries through the switch. The switch
completes the circuit. The lamp gets bright as
electricity flows through it.
Snappy says the lamp contains
a special thin high-resistance
wire. When a lot of electricity
flows through it, it gets so hot it
glows bright.
The air is being blown down through the blade
and the motor rotation locks the fan on the shaft.
When the motor is turned off, the blade unlocks
from the shaft and is free to act as a propeller
and fly through the air. If speed of rotation is too
slow, the fan will remain on the motor shaft
because it does not have enough lift to propel it.

! WARNING: Moving parts. Do not touch the
fan or motor during operation. Do not lean
over the motor.
WARNING: Fan may not rise until switch is
released.

Build the circuit shown on the left by placing the parts
with a black 1 next to them on the base grid first.
Then, assemble parts marked with a 2. Place the
glow fan on the motor. New alkaline batteries are
recommended for this project.
Turn on the slide switch (S1), wait for the motor to
reach full speed, then turn off the switch. The glow
fan should rise and float through the air like a flying
saucer. Be careful not to look directly down on the
glow fan when it is spinning.
If the fan doesn’t fly off, then turn the switch on and
off several times rapidly when it is at full speed.
The glow fan will glow in the dark. It will glow best
after absorbing sunlight for a while. The glow fan is
made of plastic, so be careful not to let it get hot
enough to melt. The glow looks best in a dimly lit
room.
