ARNING: SHOCK HAZARD -

ever connect Snap Circuits

to the electrical outlets in your

home in any way!

ARNING: Always check your wiring before

turning on a circuit. Never leave a circuit

unattended while the batteries are installed.

Never connect additional batteries or any other

ower sources to your circuits.

Assembling the Liquid Energy Source:

The clock (T2) contains a small crystal. When a crystal

is struck by an electronic pulse, it vibrates. A

microelectronic circuit makes the pulse and measures

the vibration rate. The vibration rate is used as a time

standard, from which minutes, hours, and the date are

calculated.

The red and black

wires are wires

used to connect

components. They

are used to transport

electricity and do not affect circuit

performance. 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.

About Your Parts:

The liquid energy source (liquid holder and

electrodes): Cola-flavored soda is lightly acidic. The

acid is similar to the material used in some types of

batteries but not as strong. The acid in the cola reacts

with the copper and zinc electrodes to make electricity,

just like a battery. As some of the acid in the soda is

used up, the electricity produced drops.

Each of the compartments in the liquid energy source

produces about 0.7V, though the current is very low.

When the four compartments are connected in a series,

their voltages add together to make about 2.8V total.

Each compartment is like a cell of a battery.

The red LED (D1) 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) electricity flows if the voltage exceeds a turn-on

threshold (about 1.5V); brightness then increases.

Once turned on, LEDs produce light much more

efficiently than incandescent light bulbs. LED’s block

electricity in the “reverse” direction.

Connect the 3 electrode parts together with screws and

nuts as shown. Tighten by hand, a screwdriver is not

needed.

The 470mF capacitor (C5) can store electrical pressure

(voltage) for periods of time. Capacitors are used for

filtering and delay circuits.
