Install six “AA” batteries (not included) into the bottom of the Rover body and one 9V battery (not included) into the remote control unit. Install the antenna into the remote control unit by screwing it in.

The Deluxe Snap Rover®Kit 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, LED blocks, different length wire bloc ks , etc. These bloc ks are in different colors and have numbers on them so that you can easily identify them. The circuit you will build is shown in color and numbers, identifying the blocks that you will use and snap together to for m a circuit.

For Example:

This is the switch block which is green and has the marking on it.

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.

A large clear plastic base grid is included with this kit to keep the circuit blocks together, it fits on top of the Rover body. You will see evenly spaced posts that the diff erent b loc ks snap onto, these keep your circuit together. The base has rows labeled A-G and columns labeled 1-10.

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.

Jumper wires are used to connect your circuits to the batteries and motors in the Rover body. Snap them on as shown in the projects. The colors are interchangeable, so it doesn’t matter which color you use (however the red and black wires are longer than the rest).

Note: While building the projects, be careful not to accidentally make a direct electrical connection across the + and – snaps for the batteries (a “short circuit”), as this may damage and/or quickly drain the batteries.

How To Use It

Warning to Snap Circuits®owners: Do not use parts from other Snap Circuits

sets with this kit unless directed to do so. The Snap

Rover

uses higher voltage which could damage those parts. Page 44 and our website www.snapcircuits.net has approved circuits that you can use.

(Part designs are subject to change without notice). The

base grid is a platform for mounting parts and wires. It

functions like the printed circuit boards found in most electronic products, or like how the walls are used for mounting the electrical wiring in your home.

The blue

snap wires are just wires used to connect other

components, 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 red, black, white, orange, yellow, green, gray, and purple

jumper wires make flexible connections for times when using the

snap wires would be difficult. They also are used to make connections off the base grid. The different colored wires all work the same way, and are interchangeable. Wires transport electricity just like pipes are used to transport water.

The

batteries (in the Rover body) produce an electrical voltage

using a chemical reaction. This “voltage” can be thought of as electrical pressure, pushing electrical “current” through a circuit just like a pump pushes water through pipes. This voltage is m uch lower and much safer than that used in your house wiring. Using more batteries increases the “pressure” and so more electricity flows.

The

slide switch (S1) connects (ON) or disconnects (OFF) the

wires in a circuit. When ON it has no effect on circuit performance. It turns on electricity just like a faucet turns on water from a pipe.

The

press switch (S2) connects (pressed) or disconnects (not

pressed) the wires in a circuit, just like the slide switch does. Resistors, such as the

100Ω (R1), 1KΩ (R2), 10KΩ (R4), and

100KΩ (R5) resistors

, “resist” the flow of electricity and are used to control or limit the electricity in a circuit. Note that “K” means 1000, so R4 is really 10,000Ω. Increasing circuit resistance reduces the flow of electricity.

The

LED (D4) is a light emitting diode, and may be thought of as a

special one-way light bulb. In the “forward” direction (indicated by the “arrow” in the symbol) electr icity flows if the voltage exceeds a turn-on threshold (about 3V); brightness then increases. A high current will burn out the LED, so the current must be limited by other components in the circuit. LEDs block electricity in the “reverse” direction.

The

1μF (C7) and 100μF (C4N) capacitors are components that

can store electrical pressure (voltage) for periods of time, higher values have more storage. Because of this storage ability they block unchanging voltage signals and pass fast changing voltages. Capacitors are used for filtering and delay circuits.

The

Deluxe Receiver (RX2) is a complex module containing a

radio receiver circuit, a specialized radio decoder integ r ated circuit, and other supporting components. It includes resistors, capacitors, inductors, and transistors that are always needed together. This was done to simplify the connections you need to make, otherwise this circuitry would not fit on the base grid. A description for this module is given here for those interested, see Project #1 for a connection example:

About Your Snap Circuits®Parts (continued)

The Sound & Recording IC (U9) module contains an integrated recording circuit, a dual timer integrated circuit for making audio tones, microphone, speaker, filtering circuitry, and other supporting components. It includes resistors (adjustable and fix ed), capacitors, transistors and diodes that are needed to make the recordings and play all the sounds. Recording time is up to 12 seconds. A description for this module is given here for those interested, see Project #1 for a connection example and for instructions on how to use it:

The

motors (in the Rover body) convert elecricity into mechanical

motion. 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 is a coil of wire with many loops wrapped around metal plates. If a large electric current flows through the loops, it will turn ordinary metal into a magnet. The motor shell also has a magnet on it. When electricity flows through the coil, it magnetizes the metal plates and they repel from the magnet on the motor shell - spinning the shaft. A small gear is on the end of the shaft and spins with it.

The

Disc Launcher (DL) contains two motors. One motor starts

first and spins a cylinder at high speed. Another motor starts a few seconds later and slowly moves a disc into launch position using gears and a hook. When the disc enters launch position the cylinder grabs it and propels it out of the launcher. The motors are controlled by an integrated circuit along with resistors, capacitors, and transistors. The same circuit also controls the lights in the “eyes”. A description for this module is given here for those interested, see Project #1 for a connection example:

Remote Control Transmitter:

When the levers in the Remote Control Unit are pushed, electrical contacts are made connecting the 9V battery power to the transmitter, indicating which commands the user wants sent to the Rover. Forwards/Backwards commands for each set of wheels and two extra functions are controlled by different levers or buttons. Each of these use a different set of electrical contacts which encode a sequence of electrical pulses; the pulse sequence depends on which command(s) are being sent. The spacing between the sequences represents which channel setting (A-B-C) the remote control is on. This allows three units to use the same operating frequency in the same room at the same time without interfering with each other. An electrical circuit that is tuned to a frequency of 27 MHz creates a signal that is sent to the antenna when the pulses are active. The antenna converts this electrical energy into radio energy, creating a stream of radio energy bursts, which travel through the air and are picked up by, and understood by, the radio receiver in the car . The frequency of 27 MHz was selected for y our Rov er with the approval of the FCC (the US government) to minimize radio interference between this product and all other electrical products.

Radio Receiver:

The Rover antenna collects radio energy and converts it back into electrical energy. If the Rover is turned on, then the radio receiver in the Rover is continuously monitoring the radio energy from its antenna. The receiver is basically a filter which is tuned to amplify any energy around 27 MHz and block energy the antenna picks up outside this region. If the Remote Control Transmitter is sending commands, then its radio signal

will be picked up by the receiver and converted back into the original pulse sequence. Decoding circuitr y then determines which commands were sent by examining the pulses in the sequence. Signals are then sent to motors that drive the wheels to execute the commands, or the other R/C Receiver outputs to control other functions. Commands sent to other receivers using a different channel setting (A-B-C) are ignored.

Characteristics of Radio Reception:

Many factors affect the ability of the Rover to receive commands from its Remote Control Transmitter. A weak batter y in the Transmitter will result in a weaker transmitted signal; if the battery is very weak then the Transmitter may not function at all. The Transmitter’s ability to convert electrical energy to radio energy is best when its antenna is fully extended and degrades as the antenna length is reduced. The same thing also applies to the Rover antenna’s ability to convert the radio signal back into electrical energy for the receiver. The Transmitter’s antenna transmits energy in all directions so as the range between it and the Rover is increased, less energy is received at the Rover. When operated with strong batteries and in an open area, the range will be at least 25 ft. Obstacles such as walls, furniture, and trees will degrade the radio signal’s ability to travel through air and reduce the operating range, but will never block it completely. In some cases more radio energy may travel from the Transmitter to the Rover by going around obstacles than by going through them. In the Rover, weak batteries will reduce power to the motor and degrade the receiver’s ability to filter, amplify, and decode commands from the Transmitter.

How It Works (continued)

Rover Drive Mechanism:

The small gear on the Motor drives a larger gear, which drives a larger gear, which drives two larger gears (one on each side), which drive larger gears. The last, largest gears are fixed on shafts that are attached to the front and back wheels, making them move. Note that interlocking gears spin in opposite directions. Also notice that in the sets of interlocking gears between the Motor and the gears on the wheel shafts, the number of “teeth” is increased each time (40-8, 448, 64-44, and 64-20), for 128:1 gear ratio overall. This means the Motor must rotate 128 times to rotate the wheels once. The reason for this is that if the Motor were to drive the wheels directly then the Rover would be so fast that it would be impossible to control. Using the gears to reduce the speed also makes the wheels move with much greater force, preventing the Rover from getting stuck in rough terrain and allowing it to carry heavy loads uphill.

Build the circuit for Project #1.

Set the channel switches on the remote control unit and Deluxe Receiver module (RX2) to the same setting (A, B, or C).

Place the Rover on a flat, open area, turn the ON/OFF switch on the remote control unit and the slide switch (S1) to ON, and extend the antenna on the Remote Control.

Push both levers forward to make Snap Rover

go forward. Push both levers backward to go backward. Push the left lever backward and the right lever forward to turn left. Push the left lever forward and the right lever backward to turn right.

The buttons on the remote control unit are used to control the disc launcher, sounds, or other special functions as described in the projects. The functions of the sound & recording IC (U9) are described in Project #1.

Never operate Snap Rover

in the street.

Never drive your Rover in rain, snow, mud, sand, dir t, or on a wet floor, as damage may result.

After building the circuits given in this booklet, you ma y wish to e xperiment 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 resistor, motor, integrated circuit, etc.), and wiring paths between them and back.

You must be careful not to create “short circuits” (very lowresistance paths across the batteries, see examples below) as this will damage components

and/or quickly drain your batteries. Only connect the

ICs using configurations given in the projects, incorrectly doing so may damage them. Elenco®Electronics 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 resistor, motor , or the disc launcher, RX2, and U9 modules (which must be connected properly).

ALWAYS use the LED and 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 par ts.

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. ALWAYS connect the disc launcher, RX2, and U9 modules using

configurations given in the projects or as per the connection descriptions for the parts.

NEVER connect to an electrical outlet in your home in any way. NEVER leave a circuit unattended when it is turned on.

For all of the projects given in this book, the parts may be arranged in different wa ys 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.

WARNING: SHOCK HAZARD - Never connect Snap Circuits®to

the electrical outlets in your home in any way!

Examples of SHORT CIRCUITS - NEVER DO THESE!!!

You are encouraged to tell us about new circuits you create. If they are unique, we will post them with your name and state on our website at www.snapcircuits.net/kidkreations.htm. Send your suggestions to Elenco

Electronics.

DO’s and DON’Ts of Building Circuits

Placing a jumper wire directly across the battery snaps is a SHORT CIRCUIT.

When the switch (S1) is turned on, this large circuit has a SHORT CIRCUIT path (as shown by the arrows). The short circuit prevents any other portions of the circuit from ever working.

Advanced Troubleshooting (Adult supervision recommended)

Elenco®Electronics is not responsible for parts damaged due to incorrect wiring.

If you suspect you have damaged par ts, you can follow this procedure to systematically determine which ones need replacing:

1. Rover body and jumper wires: Flip the Rover body upside down and make sure the wheel mechanisms are clean. Install batteries in the Rover body and connect jumper wires to the Rover rear as shown; two wheels should move. Replace the orange and gray jumper wires with each of the other colors to see if any of the jumpers are damaged. If the wheels don’t move for any combination of wires, then the Rover body is damaged. Remo ve the gray wire; four LEDs on the side should light.

Now move the jumper wires to test the other two wheels, if they don’t move then the Rover body is damaged. Remo ve the gray wire; four LEDs on the side should light.

Slide switches (S1) and press switch (S2): Build Project #51 (Helpless

Rover) and test each slide switch by making it tur n the wheels on/off. Replace the slide switch with the press switch; it works the same way.

Snap wires: Build Project #6 but replace the switch with each of the snap

wires (including the 1-snaps), test them one at a time.

4. White LED (D4) and 100Ω, 1KΩ, 10KΩ, and 100KΩ resistors (R1, R2, R4,

R5):

Build this mini-circuit and turn on the switch, the LED should be bright or it is damaged. Replace the 3-snap with each of the resistors (one at a time), the LED should be bright with R1, slightly dimmer with R2, much dimmer with R4, and very dim with R5; if not then the resistor is defective.

Disc Launcher (DL) module: Build Project #42 (Disc Launcher). The launcher

should start up and launch discs as described. If the launcher is jammed, turning off the circuit and removing all discs can usually fix it.

Sound & Recording IC (U9) and the 1μF and 100μF capapacitors (C7, C4N):

Build Project #62 (Lunar Messenger); the parts should work as

described in it.

Remote control unit and Deluxe Receiver (RX2): Build Project #36 (Remote

Control Right Lite) and test that the wheels and white LED (D4) can be controlled by the remote control unit as described. Be sure you have built the circuit correctly and have good batteries in both the Rover body and remote control. Ha ve the A-B-C switches on the remote control and deluxe receiver set to the same channel, have turned on the remote control turned on and its antenna extended, and make sure it is not being interf ered with by other remote control transmitters.

Snap Circuits®: The Snap Circuits®Kit

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 that you can easily identify them.

Preparation: Install six (6) “AA” batteries into the bottom of the Rover body and one 9V battery into the remote control unit (batteries not included). Install the antenna into the remote control unit by screwing it in. Place the base grid on the Rover body; you may lock it into position by turning the hexagonal alignment posts (shown here), if desired.

Assembly: Build the circuit shown by placing all the parts with a black 1 next to them on the clear plastic base grid first. Then, assemble parts marked with a 2, and finally the parts marked with a 3. Be sure to place the D4 (black), RX2 (red), and U9 (orange) parts with their (+) side oriented as shown. Connect the black colored jumper wire as shown and connect the

other colored jumper wires to the rear of the body as shown (the colors are interchangeable). Set the channel switches on the remote control unit and Deluxe Receiver module (RX2) to the same setting (A, B, or C).

Recording & Sounds: Turn on the slide switch (S1). The recorded message (if any) will play, followed by space sounds. Turn either of the knobs on the sound & recording IC (U9) to adjust the tone and beat of the sounds. Push and hold the press switch (S2) and speak into the microphone on U9 to record a message of up to 12 seconds. The red light on U9 will be on while you are recording.

Remote Control: Turn on the remote control unit, extend the antenna, and use the levers to drive the Ro v er around. Press the left button on the remote control to play the recorded message (if any).

Launching Discs: Place some of the foam discs into the disc launcher (DL). Press the right button on the remote control to prepare the launcher; the eyes flash. The launcher takes a few seconds to get ready, then press the right button again to fire or hold it down to fire continuously. The launcher shuts off after a few seconds. If the launcher jams, just remove the discs to fix it. The white LED (D4) lights up when the launcher is active, so you can launch discs in the dark.

Modify the Project #1 circuit by adding a second slide switch (S1) over the U9 sound and recording IC, using two 1-snaps as shown. The circuit works the same as before except turning on the new S1 switch shuts off the space sounds.

Now your Rover can sneak up on someone, play your recording, and launch the discs!

As an option, change the sound into just a simple tone by removing the 2snap wire on the upper-right of U9 (on level 3).

Modify the Project #2 circuit by adding a the 100μF capacitor (C4N) over the 10K resistor (R4), using a 1-snap as shown. The circuit works the same as before except that the space sounds sound a little diff erent. Turn knobs on U9 to change the sound.

Next replace the 10K resistor (R4) with either the 1K resistor (R2) or the 100K resistor (R5), and turn the knobs on U9 to see how the range of sounds has been changed.

Now replace the 100μF capacitor (C4N) with the 1μF capacitor (C7), and turn the knobs on U9 to see how the range of sounds has been changed. Try different combinations of resistor and capacitor values.

Changing the resistor and capacitor values adjusts an electronic delay, which changes the sound effects in an electrical signal controlling a speaker (SP).
