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 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 , , , ,

or 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 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.

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 A-

G 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.

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 thru-

snaps. 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.

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.

The 45 degree vertical snap wire (V2) is similar

to V1 but mounts at a 45 degree angle

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.

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 stabilizer is used to connect base grids on

their corners or edges. With eight slots, the

stabilizer allows the base grids to be mounted

in increments of 45 degrees. To attach the

stabilizer to the base grid, simply align 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).

The clear motor (M4) will often have the wind

fan mounted on it; simply push the fan onto the

shaft. To remove it, push up on it with a

screwdriver or your thumbs, being careful not

to break it.

This set contains three LED attachments, which

can be mounted on the LED modules (D9, D11,

and D12) to enhance their light effects. The egg

attachment is mounted directly on the LEDs,

but

the fiber optic festive tree must be mounted

using the mounting base, as shown. This is

described in the projects.

In some

projects the mirror ball is placed on the orange

Parts

(Part designs are subject to change without notice).

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.

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 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

other switches do.

The blue snap

wires are wires

used to connect

c o m p o n e n t s .

They are used

to transport

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.

Wires transport electricity just like pipes are

used to transport water. The colorful plastic

coating protects them and prevents electricity

from getting in or out.

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.

Parts

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.

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.

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.

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 built-

in 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 sub-

atomic charged particles (called electrons) through a material due to electrical

pressure across the material, such as from a battery.

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).

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.

There are two ways of arranging parts in a circuit, in series or

in parallel. Here are examples:

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.

WARNING: SHOCK HAZARD - Never connect Snap Circuits

®

to the electrical outlets in your home in any way!

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.

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 mini-

circuit 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.

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.

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.

+

Project 2 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.

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 3 Red Light

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.

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.T he festive tree and egg may also be used

with other Snap Circuits® LEDs from different sets.

Project 4 Lamp Light

Modify the preceding circuit to be this

one. Turn on the slide switch (S1) to light

the lamp (L4).

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.

Project 5

Play a Melody

Build this circuit, then turn on the slide

switch (S1) to play a melody with the

melody IC (U32).

Project 6

Build the circuit shown, and place the fiber optic festive

tree in its mounting base and on the blink red LED (D11).

Turn on the slide switch (S1) and enjoy the show.

This circuit has four lights, 2 motors,

and music. Lights, sound, & motions!

Project 7 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.

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).

Note: if the LED assembly fit seems

loose, add a 1-snap wire between

one of the 3D snaps and a V1.

+

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 8

Rotation

Lights

The 3D snaps enable

you to rotate a light to

any position.

Project 9 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

Build the circuit and place the mirror ball on the

orange motor (M9). Turn on the slide switch (S1) to

spin the mirror ball.

Assembly (adult supervision recommended):

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.

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.

3. Mount parts on grids B & C, and install in base grid supports in grid

A. The pegs should be facing inward.

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

and small gears should align.

5. Place remaining parts on grid A.

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.
