How to Use Circuit Maker Skill Builder 125

Circuit Maker Skill Builder 125 uses building

blocks with snaps to build the different

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 switch block which 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 two (2) 1.5V

“AA” batteries (not included).

A large clear plastic base grid is 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 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.

Usually when the motor is used, the glow

fan will be placed on it. On top of the motor

shaft is a black plastic piece (the motor top)

with three little tabs. Lay the fan on the black

piece so the slots in its bottom “fall into place”

around the three tabs in the motor top. If not

placed properly, the fan will fall off when the

motor starts to spin.

Note: While building the projects, be

careful not to accidentally make a direct

connection across the battery holder (a

“short circuit”), as this may damage and/or

quickly drain the batteries.
