|
Elenco's new snap circuits make learning electronics
easy and fun! Just follow the colorful pictures in our manual
and build exciting projects such as AM radios, burglar alarms,
doorbells and much more! You can even play electronic games
with your friends. All parts are mounted on plastic modules
and snap together with ease. Enjoy hours of educational fun
while learning about electronics. No tools required.
This basic Snap Circuits Junior kit has over 30 different electronic
components, including three integrated circuits, a photo-resistor,
switches, a motor, and speaker. The manual included colored
illustrations showing how to build the models. You provide two
AA batteries and help for younger children. Ages 8+. Click here for larger image.

Snap Circuits SC-100 Project
Examples

Flying Saucer
OBJECTIVE: To make a circuit that launches the fan
blade to simulate a flying saucer
New alkaline batteries are recommended for this project.
When you close the slide switch (S1), the motor will
slowly increase in speed. When the motor has reached
maximum rotation, turn the slide switch off. The fan
blade should rise and float through the air like a flying
saucer. Be careful not to look directly down on fan
blade when it is spinning.
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 motor shaft because it does not have enough
lift to propel it. The motor will spin faster when both
batteries are new.

Laser Gun
OBJECTIVE: To show how integrated circuits sound
can easily be changed to exciting laser gun sounds.
Build the circuit shown on the left by placing all the
parts with a black 1 next to them on the base grid first.
Then, assemble parts marked with a 2.
When you close the slide switch (S1), the integrated
circuit (U2) should start sounding a laser gun sound.
This integrated circuit is designed to produce different
sounds that can easily be changed. You can even switch
the sound on and off quickly to add sound effects to
your games or recordings.

Space War
OBJECTIVE: To introduce you to the space war integrated
circuit and the sounds it can make.
Build the circuit shown on the left, which uses the
space war integrated circuit (U3). Activate it by flipping
the slide switch (S1) or pressing the press switch (S2);
do both several times and in combination. You will hear
an exciting range of sounds, as if a space war is raging!
Like the other integrated circuits, the space war IC
is a super- miniaturized electronic circuit that can
play a variety of cool sounds stored in it by using
just a few extra components.
In movie studios, technicians are paid to insert these
sounds at the precise instant a gun is fired. Try making
your sound occur at the same time an object hits the
floor. It is not as easy as it sounds.

Reflection Detector
OBJECTIVE: To detect if a mirror is present.
Build the circuit at left. Place it where there won’t
be any room light hitting the photoresistor (RP) (such
as in a dark room or under a table), and then turn it
on. The 2.5V lamp (L1) will be bright but there should
be little or no sound.
Take a small mirror and hold it over the lamp and photoresistor.
You should hear sound now. You have a reflection detector!
The more light that gets reflected like this, the louder
the sound. You can try holding the mirror at different
angles and distances and see how the sound changes.
You can also hold a white piece of paper over them,
since white surfaces reflect light.

Space War Music Combo
OBJECTIVE: To combine the sounds from the space war
and music integrated circuits.
Build the circuit shown and add the jumpers to complete
it. Turn it on, press the press switch (S2) several
times, and wave your hand over the photoresistor (RP)
to hear all the sound combinations. If the sound is
too loud you may replace the speaker (SP) with the whistle
chip (WC).
