How to Use Snap Circuits®
Snap Circuits® uses building blocks with snaps
to build the different electrical and electronic
circuits in the projects. Each block has a
function: there are switch blocks, light blocks,
battery blocks, different length wire blocks, etc.
These blocks are different colors and have
numbers on them so that you can easily
identify them. The blocks you will be using are
shown as color symbols with level numbers
next to them, allowing you to easily snap them
together to form a circuit.
For Example:
This is the slide switch, it is green and has the
marking S1 on it. The part symbols in this
booklet may not exactly match the appearance
of the actual parts, but will clearly identify them.
This is a wire block which is blue and comes
in different wire lengths.
This one has the number 2 , 3 , 4 , 5 ,
or 6 on it depending on the length of the wire
connection required.
There is also a 1-snap wire that is used as a
spacer or for interconnection between different
layers.
You need a power source to build each circuit.
This is labeled B3 and requires three (3) 1.5V
“AA” batteries (not included).
When installing a battery, be sure the spring
is compressed straight back, and not bent up,
down, or to one side.
Some circuits use the jumper wires to make
unusual connections. Just clip them to the
metal snaps or as indicated.
When assembling the 3D circuits, the order in
which parts are installed is important. In
particular, the vertical snap wires (V1) need to
be snapped onto the mini base grid first and
then the mini base grid is slid into the base grid
support as shown below. One of the small
grids has pegs on both sides and six thrusnaps. Some projects will indicate that this grid
must be (or must not be) used in a specific
location, otherwise it may be used
interchangeably with the other small grids.
One large and four smaller clear plastic base
grids are included with this kit to help keep the
circuit blocks properly spaced. You will see
evenly spaced posts that the different blocks
snap into. The large base has rows labeled AG and columns labeled 1-10, and the small
base has rows labeled A-E and columns
labeled 1-7. It should be obvious whether to
use a small base grid or a large base grid. For
small circuits that only need one grid, either
size may be used.
Next to each part in every circuit drawing is a
small number in black. This tells you which
level the component is placed at. Place all
parts on level 1 first, then all of the parts on
level 2, then all of the parts on level 3, etc.

How to Use Snap Circuits®
Due to the complex nature of building 3D
circuits, the circuit diagrams use special
symbols that may need additional clarification.
One such example is the symbol for the
vertical snap wire (V1). It consists of two parts,
the horizontal base and vertical stem. In the
illustration below, the base is attached to the
large base grid and the stem is attached to the
mini base grid. The symbol makes V1 appear
as two separate parts, but in reality the symbol
is connected at the red circular ends.
When inserting the base grid into the base grid
support, it is a good idea to insert an area on
the base grid that doesn’t have raised letters
or numbers. The raised text can interfere with
the insertion or cause a tight fit between the
base grid and base grid support.
To install the base grid support onto the base
grid, align the holes of the support with the
base grid pegs in the desired location on the
base grid and press down firmly on the base
grid support. Make sure that the base grid
support is fully seated on the base grid.
The 45 degree vertical snap wire (V2) is similar
to V1 but mounts at a 45 degree angle
The stabilizer is used to connect base grids on
their corners or edges. With eight slots, the
desired grooves in the stabilizer with the edges
of the base grids and press down. The figure
below shows how the stabilizer symbol is
presented in the manual and the 3D rendering
of the stabilizer mounted to two base grids.
Some projects use the illusion cards. Separate
them (if they came together), push one into the
Illusion card holder.
If at any point the illusion cards become to
loose to stay in the card holder you can add a
small strip of paper to insure the card fits snug
in the holder.
Then push the holder onto the shaft of the
clear motor (M4).
Another symbol of note is the base grid
support. It is important to pay attention to the
orientation of the part in the diagram since it is
not symmetrical. The figure below shows the
symbol with the narrow channel on top. This
corresponds to the 3D rendering showing the
base grid support orientation.

About Your Snap Circuits® Parts
BASE GRID
The base grids are platforms for mounting
parts and wires. They function like the printed
circuit boards used in most electronic
products, or like how the walls are used for
mounting the electrical wiring in your home.
This set has two sizes, which can be placed
together to form larger grids. One of the small
grids has pegs on both sides and 6 thru-snaps,
to allow assembly of circuits on both sides.
SLIDE & PRESS SWITCHES
The slide & press switches (S1 & S2)
connect (pressed or “ON”) or disconnect (not
pressed or “OFF”) the wires in a circuit. When
ON they have no effect on circuit performance.
Switches turn on electricity just like a faucet
turns on water from a pipe.

The blue snap
wires are wires
used to connect
components.
They are used
to

electricity and
do not affect
circuit performance. They come in different
lengths to allow orderly arrangement of
connections on the base grid.
The vertical snap wires (V1) and 45 degree
vertical snap wires (V2) make connections
between two dimensions, allowing electricity to
go up a wall.
The jumper wires (red, black, & blue) make
flexible connections for times when using the
snap wires would be difficult. They also are
used to make connections off the base grid.
BATTERY HOLDER
The batteries (B3) produce an electrical
voltage using a chemical reaction. This
“voltage” can be thought of as electrical
pressure, pushing electricity through a circuit
just like a pump pushes water through pipes.
This voltage is much lower and much safer
than that used in your house wiring. Using more
batteries increases the “pressure”, therefore, more
electricity flows.

About Your Snap Circuits® Parts
SOUND MODULE
The melody IC (U32) contains a specialized
sound-generation integrated circuit (IC), a
small speaker, and a few supporting
components. The IC has a recording of the
melody, which it makes into an electrical signal
for the speaker. The speaker converts the
signal into mechanical vibrations. The
vibrations create variations in air pressure,
which travel across the room. You “hear”
sound when your ears feel these air pressure
variations.
LAMP
A light bulb, such as in the 4.5V lamp (L4),
contains a special thin high-resistance wire.
When a lot of electricity flows through, this wire
gets so hot it glows bright. Voltages above the
bulb’s rating can burn out the wire.
LEDs
The blue, blink red, and color2 LEDs (D9,
D11 & D12) are light emitting diodes, and may
be thought of as a special one-way light bulbs.
In the “forward” direction, (indicated by the
“arrow” in the symbol) electricity flows if the
voltage exceeds a turn-on threshold
brightness then increases. The blink red LED
contains a microcircuit that turns it on and off.
The color2 LED contains red, green, and blue
LEDs, with a micro-circuit controlling them. A
high current will burn out an LED, so the
current must be limited by other components
in the circuit (Snap Circuits® LEDs have
internal resistors added, to protect them in
case you make wiring mistakes). LEDs block
electricity in the “reverse” direction.
MOTORS
The clear motor (M4) converts electricity into
mechanical motion.
An electric current
through the motor will turn the shaft. It can
also be used as a generator, since it produces
an electric current when the shaft is turned.
How does electricity turn the shaft in the
motor? The answer is magnetism. Electricity
is closely related to magnetism, and an electric
current flowing in a wire has a magnetic field
similar to that of a very, very tiny magnet.
Inside the motor are several coils of wire with
many loops. If a large electric current flows
through the loops, the magnetic effects
become concentrated enough to move the
coils. The motor has a magnet inside, so as
the electricity moves the coils to align them
with the permanent magnet, the shaft spins.
The orange motor (M9) is a motor with a builtin gearbox. The gearbox makes the shaft spin
slower but with greater force. Do not try to spin
its shaft manually to generate electricity
because you may break it. The middle snap is
only used for mechanical stability.

Introduction to Electricity
What is electricity? Nobody really knows. We only know how to produce it,
understand its properties, and how to control it. Electricity is the movement of subatomic charged particles (called electrons) through a material due to electrical
pressure across the material, such as from a battery.
There are two ways of arranging parts in a circuit, in series or
in parallel. Here are examples:
Power sources, such as batteries, push electricity through a circuit, like a pump
pushes water through pipes. Wires carry electricity, like pipes carry water. Devices
like LEDs, motors, and speakers use the energy in electricity to do things. Switches
and transistors control the flow of electricity like valves and faucets control water.
Resistors limit the flow of electricity.
The electrical pressure exerted by a battery or other power source is called
voltage and is measured in volts (V). Notice the “+” and “–” signs on the battery;
these indicate which direction the battery will “pump” the electricity.
The electric current is a measure of how fast electricity is flowing in a wire, just
as the water current describes how fast water is flowing in a pipe. It is expressed
in amperes (A) or milliamps (mA, 1/1000 of an ampere).
Series Circuit
The “power” of electricity is a measure of how fast energy is moving through a
wire. It is a combination of the voltage and current (Power = Voltage x Current). It
is expressed in watts (W).
The resistance of a component or circuit represents how much it resists the
electrical pressure (voltage) and limits the flow of electric current. The relationship
is Voltage = Current x Resistance. When the resistance increases, less current
flows. Resistance is measured in ohms (W), or kilo ohms (kW, 1000 ohms).
Nearly all of the electricity used in our world is produced at enormous generators
driven by steam or water pressure. Wires are used to efficiently transport this
energy to homes and businesses where it is used. Motors convert the electricity
back into mechanical form to drive machinery and appliances. The most important
aspect of electricity in our society is that it allows energy to be easily transported
over distances.
Note that “distances” includes not just large distances but also tiny distances. Try
to imagine a plumbing structure of the same complexity as the circuitry inside a
portable radio - it would have to be large because we can’t make water pipes so
small. Electricity allows complex designs to be made very small.
-9-
Parallel Circuit
Placing components in series increases the resistance; highest
value dominates. Placing components in parallel decreases the
resistance; lowest value dominates.
The parts within these series and parallel sub-circuits may be
arranged in different ways without changing what the circuit
does. Large circuits are made of combinations of smaller series
and parallel circuits.
SC-3DMEG_Manual.qxp_SC-3Di_Manual_060816 6/19/17 7:30 PM Page 11
DOs and DON’Ts of Building Circuits
After building the circuits given in this booklet, you may wish to experiment on your
own. Use the projects in this booklet as a guide, as many important design concepts
are introduced throughout them. Every circuit will include a power source (the
batteries), a resistance (which might be a motor, melody IC, or LED (which has an
internal protection resistor), etc.), and wiring paths between them and back. You
must be careful not to create “short circuits” (very low-resistance paths across the
batteries, see examples below) as this will damage components and/or quickly drain
your batteries. Elenco® is not responsible for parts damaged due to incorrect
wiring.
Here are some important guidelines:
ALWAYS USE EYE PROTECTION WHEN ExPERIMENTING ON YOUR OWN.
ALWAYS include at least one component that will limit the current through a
circuit, such as a motor, melody IC, or an LED (which has an internal
protection resistor).
ALWAYS use switches in conjunction with other components that will limit the
current through them. Failure to do so will create a short circuit
and/or damage those parts.
ALWAYS disconnect your batteries immediately and check your wiring if
something appears to be getting hot.
ALWAYS check your wiring before turning on a circuit.
NEVER connect to an electrical outlet in your home in any way.
NEVER leave a circuit unattended when it is turned on.
NEVER try to turn the shaft of the orange motor (M9) by hand or with tools, as
this may break it.
For all of the projects given in this book, the parts may be arranged in different
ways without changing the circuit. For example, the order of parts connected in
series or in parallel does not matter — what matters is how combinations of
these sub-circuits are arranged together.
3D Construction: Motors or other parts that produce motion (which you may
have from other snap Circuits® sets) should only be mounted overhead or on
walls with great care, as the vibrations they produce could cause them to fall.
The circuits in this set have been checked with the parts shown in them.
!
Warning to Snap Circuits® owners: Do not connect
additional voltage sources from other sets, or you may
damage your parts. Contact ELENCO® if you have questions
or need guidance.

Advanced Troubleshooting (Adult supervision recommended)
Elenco® is not responsible for parts damaged due to incorrect
wiring.
If you suspect you have damaged parts, you can follow
this procedure to systematically determine which ones
need replacing:
1. Lamp (L4), blue LED (D9), blink red LED (D11), color2 LED
(D12), melody IC (U32), and battery holder (B3): Place
batteries in holder. Place the lamp directly across the battery
holder, it should light. Place the LEDs (D9, D11, & D12) directly
across the battery holder one at a time (LED + to battery +),
the LED should light (D11 should be blinking, and D12 should
slowly change colors). Place the melody IC directly across the
battery holder (+ to +), it should play a tune. If none work, then
replace your batteries and repeat, if still bad then the battery
holder is damaged.
2. Clear motor (M4) and orange motor (M9): Place the clear
motor directly across the battery holder, the shaft should spin
(you can place the green fan on the shaft so the spinning is
easy to see). Place the orange motor directly across the battery
holder (note that the middle snap on the motor is not used), the
shaft should spin.
3. Jumper wires: Use this minicircuit to test each jumper wire,
the lamp should light.
4.Vertical snap wires (V1) and 45
degree vertical snap wires (V2):
Use this mini-circuit to test each of
the vertical snap wires (V1 & V2),
one at a time. The lamp should
light.
-11-
5. Snap wires: Use this mini-circuit to test each of the snap
wires, one at a time. The lamp
should light.
6. Slide switch (S1), press switch (S2), and reed switch (S9):
Build project 1; if the color2 LED (D12) doesn’t light then the
slide switch is bad. Replace the slide switch with the press
switch to test it. Replace the press switch with the reed switch
and hold the magnet near it to test it, there should be a magnet
position that turns on the LED, or the reed switch is bad.

Project 1
Color Light
Snap Circuits® uses electronic blocks that snap onto a clear plastic base grid to build
different circuits. These blocks have different colors and numbers on them so you can
easily identify them. This set contains both large (11” x 7.7”) and small (7.7” x 5.5”) base
grids; you may use either size for this small circuit.
Placement
Level
Numbers
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. Install three (3) “AA” batteries
(not included) into the battery holder (B3) if you have not done so already; be sure the
battery springs are compressed straight back, and not bent up, down, or to one side.
+
Turn on the slide switch (S1), and enjoy the light show from the color2 LED (D12). For
best effects, place one of the LED attachments (fiber optic festive tree or egg), and dim
the room lights. The fiber optic festive tree must be used with its mounting base.
LED Attachments
Snappy says when you turn on the slide switch,
electricity flows from the batteries, through the
color LED and back to the battery through the
switch. If the switch is off, the flow of electricity is
blocked, and the color2 LED won’t light.
LEDs are light emitting diodes, which convert
electrical energy into light. The color of the light
depends on the characteristics of the material used
in them. The color2 LED actually contains separate
red, green, and blue lights, with a micro-circuit
controlling them; the colors can be combined to
produce yellow, cyan, purple, and white.
Project 2
NOTE: this circuit (and many others in this book) have an LED
being used without a resistor or other component to limit the
electric current through it. Normally this could damage an LED but
your Snap Circuits® LEDs include internal protection resistors, and
will not be damaged. Be careful if you later use other electrical sets
with unprotected LEDs.The festive tree and egg may also be used
with other Snap Circuits® LEDs from different sets.
Blue Light
Modify the preceding circuit by replacing the color2
LED (D12) with the blue LED (D9), as shown. The
blue LED is brighter, but does not change colors.

Project 3 Red Light
Modify the preceding circuit by replacing
the blue LED (D9) with the blink red
LED (D11), as shown. The blink red
LED flashes about once a second.

Project 4
Modify the preceding circuit to be this
one. Turn on the slide switch (S1) to light
the lamp (L4).
Project 6
-15-
Lamp Light
The lamp (L4) converts electricity into light. It is an
incandescent light bulb, just like other incandescent bulbs
in homes except smaller. In an incandescent bulb
electricity heats up a high-resistance wire until it glows,
producing light. Incandescent light bulbs are very
inefficient, converting less than 5% of the electricity used
into light, with the rest becoming heat.
LEDs are much more efficient than incandescent light
bulbs, and are increasingly being used for home lighting
and flashlights.

Play a Melody
Build this circuit, then turn on the slide
switch (S1) to play a melody with the
melody IC (U32).
Fun Seven
This circuit has four lights, 2 motors,
and music. Lights, sound, & motions!
Build the circuit shown, and place the fiber optic festive
tree in its mounting base and on the blink red LED (D11).

Rotation Light
Build the circuit as shown; it has
two 3D snaps mounted on two 90
degree vertical snap wires (V1),
and then the color2 LED (D12) is
mounted on the 3D snaps.
The 3D snaps enable
you to rotate a light to
any position.
Turn on the circuit and the color2
LED lights. Rotate the LED to any
position.
You can replace the color2 LED
with the blue LED (D9), blink red
LED (D11), or lamp (L4).
Project 8
Rotation
Lights
Use the preceding circuit
but add a second light
(blue LED (D9), blink red
LED (D11), or lamp (L4)) to
the female snaps on the
3D snaps, as shown. The
“+” side of the LEDs should
be oriented to the right.
Project 9
Note: if the LED assembly fit seems
loose, add a 1-snap wire between
one of the 3D snaps and a V1.
Fan
Build the circuit and place the wind fan on the clear motor
(M4). Turn on the slide switch (S1) to spin the fan. Place
your hand near the fan without touching it, and you can feel
air being blown up towards you.
+
Project 10
Suction Fan
Use the preceding circuit but reverse the clear
motor (M4). Now the fan sucks air downward.
Project 11 Mirror Ball

2. Mount the blue & color2 LEDs (D9 & D12) to the 3D snaps, and
attach the large gear and a 1-snap wire, as shown. The teeth on the
gear should face the LEDs, and the “+” side of the LEDs should be
towards the gear.
Turn on the slide switch (S1). The color2 and blue LEDs should light,
and be rotated by the gears.
Note: If the gears do not rotate properly, you may get better
performance if you spread the tops of the mini base grids apart. You
can do this by adding another base grid as a “roof” and securing with 4
stabilizers, as done in project 20.
1. Place base grid supports and orange motor (M9) on base grid A.
Place the small gear on the gear insert and mount on the orange
motor. The teeth on the gear should face up.
3. Mount parts on grids B & C, and install in base grid supports in grid
A. The pegs should be facing inward.
5. Place remaining parts on grid A.
4. Mount the LED assembly from step 2 between the 5-snap wire on
grid B and the 2-snap wire on grid C, as shown. The teeth on the large

Use either of the preceding circuits but replace one
of the lights with the clear motor (M4), and place the
green fan on the motor. Don’t place the motor next
to the melody IC (U32), and be sure that the fan
won’t hit any of the LED attachments.

Assembly:
1. Place base grid supports on base grid A.
2. Install grids B & D into base grid supports on grid A. The pegs can be pointed in either direction.
3. Mount grid C on top of grids B & D using 4 stabilizers.
4. Place the remaining parts on grid A. Place the fiber optic festive tree on the color2 LED (D12) using the mounting base.
Turn on the slide switch (S1) to light the color2 LED and play a tune on the melody if (U32). This circuit looks best in a dark
room. The melody IC may be removed if desired.

Project 21
Gears can be used to make things spin faster or slower.
When one gear has more teeth than another, it will spin
slower. Using gears to reduce rotation speed also increases
the turning force, allowing it to overcome more friction. Using
gears also changes the direction of rotation.
Inside the orange motor (M9) is a motor spinning very fast,
but with little force (too little to spin both orange gears).
Several small internal gears connect the internal motor to
the metal shaft that you see; these reduce the rotation
speed, give the shaft enough force to spin the orange gears,
and also make it easier to control.
-23-
Gears
Build the circuit as shown. The large gear
is placed on the gear insert and mounted
on the orange motor (M9), and the small
gear is placed on a 3D snap which is
mounted on a stack of snap wires (a 5-snap
on level 1, 3-snaps on levels 2 and 3, a 2snap on level 4, and a 1-snap on level 5).
The teeth should be pointed up on both
gears. Turn on the slide switch (S1) to spin
the gears.
Project 22
Inverse Gear Ratio
Use the preceding circuit but swap the locations of
the large and small gears. Now the 3D snap spins
more slowly.

Project 23
Reed Switch
Build the circuit, and hold the magnet next to the reed
switch (S9) to turn on the color2 LED (D12). Move the
magnet around to turn the switch and LED on and off.
If you listen closely you may hear the reed switch
turning on or off. You can replace the color2 LED with
the lamp (L4) or the other LEDs (D9 or D11).
Project 26
The reed switch (S9) is an electrical
switch that can be controlled by a
magnet. It has two metal contacts
close together. The magnetic field
from the magnet makes the contacts
come together, completing a circuit
just like a switch does. If you look at
the reed switch contacts with a
magnifying glass then you may be
able to see them move slightly when
the magnet turns the reed switch on
and off.
An Optical Illusion
Project 24
Magnet Controlled
Sound
Use the preceding circuit but replace the color2 LED
(D12) with the melody IC (U32, “+” on left). Use the
magnet to activate the reed switch and play a tune.
Project 25
Magnet Controlled
Motor
Use the preceding circuit but replace the melody IC (U32)
with the clear motor (M4) with green fan, or the orange
motor (M9, use a 1-snap wire to support its 3rd snap) with
the mirror ball. Use the magnet to activate the reed switch
and spin the motor.
Build the circuit, and place one of the illusion
cards in the illusion card holder, and place it
on the clear motor (M4). Turn on the slide
switch (S1), then push the press switch
(S2). The motor should be spinning the
illusion card, making the pictures on each
side appear to blend together.
The motor speed will vary a little depending
on the color of the color2 LED (D12) light.
Push the press switch again if you want to
speed up the motor.
If the illusion card comes out at high speed
then insert a small piece of paper into the
cardholder with the illusion card to make it
fit more snugly. see on page 6.
Project 27
More Optical
Illusions
Use the preceding circuit but try
the other 3 illusion cards. Also
try replacing the color2 LED
(D12) with the blink red LED
(D11) for different effects. If you
have a color LED (D8) from
another Snap Circuits® set,
then you can use it in place of
the LED in this circuit. D8
changes the motor speed in
bursts, giving some different
effects.

Project 28
Funky Blinking Lights
Build the circuit and turn on the slide switch
(S1). The LEDs (D11 & D12) are blinking.
Notice that when the blink red LED (D11) is on,
the brightness of the color2 LED (D12) is lower,
because the voltage from the batteries is
divided between the two LEDs. When the blink
red LED is off, the color2 LED gets the full
battery voltage, and gets brighter.
Project 31
Use the preceding circuit
but replace the color2 LED
(D12) with the melody IC
(U32, “+” on left).
Variable Speed Fan
Build the circuit, place the wind fan on the motor
(M4), and turn on the slide switch (S1). The fan
speed varies a little depending on the color of the
color2 LED (D12). If the fan does not start spinning
then give it a push.
-25-
Project 29
Funky Sounds
The clear motor (M4) and color2 LED (D12) are connected
in series, so the voltage from the batteries is divided
between them. The electricity used by the color2 LED
varies a little depending on the color of light it is producing.
When the color2 LED uses more electricity, there is less
electricity for the motor, and the motor slows down.
Project 30
Low Funky
Sounds
Use the preceding circuit
but replace the blink red
LED (D11) with the color2
LED (D12). The sound will
vary depending on the
color of the color2 LED,
but will not be very loud
and sometimes there may
be no sound at all.
Project 32
New Speed Fan
Use the preceding circuit but replace
the color2 LED (D12) with the blue
(D9) or the blink red LED (D11).
The clear motor (M4) does not spin at full
speed because the LED is connected in
series with it. With the blink red LED, the
motor speeds up a little when the LED is
off, but it is hard to see the difference.

remove this 1-snap wire.
Assembly (adult supervision recommended):
1. Place base grid supports on base grid A.
2. Mount parts on grids B & C, and install in base grid supports in
grid A. The pegs should be facing inward.
3. Place remaining parts on grid A.
4. Mount the blue & color2 LEDs (D9 & D12) to the 3D snaps,
connect 1-snap wires on both sides, and attach to the parts on grids
B & C, as shown. The “+” side of the LEDs should be towards grid C.
Turn on the slide switch (S1). The color2 and blue LEDs light; rotate
them to any position. The circuit looks best in a dimly lit room.

Super Spinning Magnet
Assembly:
1. Place base grid supports on base grid A.
2. Mount parts on grid B (except the blue jumper wire),
and install in base grid supports in grid A. The pegs should
be facing inward.
3. Place remaining parts on grid A, including the blue
jumper wire. Note that the color LED (D12) and lamp (L4)
are mounted on the 3D snaps, which are then mounted on
the 90 degree vertical snap wires (V1).
4. Place the gear insert on the shaft of the orange motor
(M9) and place the magnet on it, centered so it balances.
Turn on the slide switch (S1). The color2 LED (D12) and
lamp (L4) light; rotate their position as
desired. The orange motor spins the magnet, and the blue
LED (D9) lights when the reed switch (S9) is triggered by
the magnet.
If desired, swap the locations of the LEDs and lamp, or
replace one with the blink red LED (D11).
Note: if the LED assembly fit seems loose, add a 1-snap
wire between one of the 3D snaps and a V1.

Assembly (adult supervision recommended):
Note: If the LED
assembly fit seems tight,
remove this 1-snap wire.
1. Place base grid support on base grid A.
2. Place parts on grid B, and install into base grid
support on grid A. The pegs should be facing inward.
Also attach the 2-snap wire to the 90 degree vertical
snap wire (V1) that hangs off the top of grid B.
3. Mount the blue & color2 and LEDs (D9 & D12) to the
3D snaps, and attach the large gear and two 1-snap
wires on opposite sides, as shown. The teeth on the
gear should face the LEDs, and the “+” side of the LEDs
should be away from the gear.
4. Place the remaining parts on grid A. Place the small
gear in the gear insert and mount on the orange motor
(M9); the teeth on the gear should face up.
5. Mount the LED assembly from step 3 between the 2snap wire that hangs upside down and the 3-snap wire
on level 4 on grid A, as shown. The teeth on the large
and small gears should align.
Turn on the slide switch (S1). The color2 and blue LEDs
should light, and be rotated by the gears. The blink red
LED (D11) is blinking (and providing mechanical
stability).

Project 37
Faster Spinning Vertical Lights
Use the preceding circuit, but carefully swap the gears, so that
the larger gear is on the motor and the small gear is on the 3D
snap. The LEDs spin faster now, but the circuit may fall apart
too easily.
The circuit is more
stable when the gears
spin slowly.

of the compass is a magnetic
north pole.
A magnetic north pole will
attract the south pole of another
magnet, and repel a north pole.

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
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.
Project 116
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.
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,

Having to turn on several switches just to turn on a lamp seems simple but is very
important. The press switch could represent an on/off switch on an electric saw,
one of the slide switches could be a safety switch on the saw, and the reed switch
could be a fuse box in your basement. Safety is very important in electrical wiring.
if switch S9, switch S1 OR switch S2 is on then the lamp will
be on. Engineers refer to this switching combination as an
OR sub-circuit (short for “this OR that”). The same type
of circuit is used throughout your home, such as having
several sensors controlling a security light.

both LEDs light. The LEDs are not bright
so dim the room lights.

Back EMF
Build the circuit as shown.
Push the press switch
(S2) for a few seconds;
the fan spins but the red
LED (D11) doesn’t light.
When you release the
switch, the red LED
flashes. Wait until the fan
stops before pushing S2
again. The red LED is not
bright so dim the room
lights to see it better.
When the switch is pressed, electricity flows from
the battery (+), through the clear motor (M4) and
press switch, then back to the negative side (-) of
the battery, but does not flow through the LED
since it is backwards.
Electric current produces a magnetic field in the
motor and when the press switch is released, the
magnetic field collapses and generates an EMF
in the electromagnet coil windings. The voltage
produced by a motor when it is spinning is called
its Back Electro-Motive-Force (Back EMF).
The voltage can only power the LED for a second.
Project 133 Lamp & Fan Independent
Build the circuit as shown.
Depending on which of the
switches (S1 & S2) are on, you
can turn on either the lamp (L4),
the clear motor (M4), or both
together. The color2 LED (D12) is
connected across the battery, so
it’s always on.

LEDs in Series
Build the circuit and close (turn on) the slide switch (S1). The LEDs (D9 &
D11) light.
Current flows from the batteries through the LEDs and back to the battery
through the switch. The closed (on) switch completes the circuit. In
electronics this is called a closed circuit. When the switch is open (off), the
current can no longer flow back to the battery, so the LEDs turn off. In
electronics this is called an open circuit. Engineers refer to switches being
open or closed because the switch symbol resembles an architect’s
symbol for a door.
Project 136
Project 135 LEDs in Parallel
When you close (turn on) the slide switch (S1), both LEDs (D9 & D11) turn
on. Current flows from the batteries through the switch back to the battery
through the LEDs. Remove the red LED (D11) and notice that the blue LED
(D9) does not change in brightness. In a parallel circuit each part has its
own path to the battery so removing one LED does not affect the other one.
The voltage is the same across the LEDs, but not the current.
Cross Over
Place the parts on the base grid, then assemble the parts on the three 90 degree
vertical snap wires (V1). The LEDs are in parallel so when you turn the switch
on, all should light.

Current Law
In this circuit, the clear motor (M4) is in series with a parallel circuit. The
parallel circuit has three current paths, S1 & D9, S2 & D11 and S9-D12.
The amount of current flow through the paths are not equal, indicated by
how fast the fan spins.
Turn on the slide switch (S1); the blue LED (D9) lights as the fan spins.
Turn the switch off.
Push the press switch (S2); the blink red LED (D11) starts blinking as the

Kirchoff's First Law:
The sum of currents flowing into a junction is equal to
the sum of currents flowing out of that junction.
Project 146
In this circuit the current from the batteries all flows
through the motor, then divides among the LEDs
whose switches are on, then recombines and flows

Compass
Project 152
1
Refrigerator
Door
All materials have tiny particles with electric
charges, but these are so well balanced that
you do not notice them unless an outside
voltage disturbs them. The same tiny particles
also have magnetic charges, which are
usually so well balanced that you do not notice
them unless a magnetic field disturbs them.
Magnets are materials that concentrate their
magnetic charges at opposite ends. One side
attracts while the other repels, but the overall
material is neutral. Most magnets are made
of iron. The name “magnet” comes from
2
1. Hold your compass away from everything, notice
that the red arrow always points north. Spin it
around, the red arrow will adjust and resume
pointing north.
The earth’s core is made of iron, which has a
magnetic field. The compass points north because
it is attracted to this magnetic field. This allows
compasses to be used for navigation.
3
magnetite, an iron ore that magnetism was
first seen in.
The earth we live on is a giant magnet, due to
its iron core. A compass needle always points
north because it is attracted to the earth’s
magnetic field. The opposite ends of a magnet
are often labeled north and south,
representing the north and south poles of the
earth. A compass actually points to the earth’s
magnetic north pole (which is in the Arctic
Ocean just north of Canada), not the
geographic north pole.
2. Now place the compass next to a large iron object,
such as a refrigerator or car. If the object is heavy
enough, the red arrow will point toward it.
Large iron objects also exert a small magnetic
field, which may attract a nearby compass. The
magnetic field is much weaker than the earth’s, but
much closer to the compass.
3. Now place your magnet near the compass. The
red arrow will immediately point toward the dark
“S” side of the magnet, ignoring a nearby
refrigerator.
Magnets have been induced to have a
concentrated magnetic field at either end. This
magnetic field is much stronger than ordinary iron
objects that may be nearby.
4. Pull out various parts in your kit and from around
your home. Decide which of these you think the
magnet will pick up, then try it and see if you were
right.
The physical properties of iron make it easy to
induce a magnetic attraction in. This doesn’t work
for other metals or other materials.
