The Radio Shack Snap Kits TM has 303 projects. They are
simple to build and understand.
Snap Kits TM 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, lamp blocks,
battery blocks, different length wire blocks, etc. These blocks
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 form a circuit.
For Example:
This is the switch block which is green and has the marking
on it as shown in the drawings. Please note that the drawing
doesn’t reflect the real switch block exactly (it is missing the ON
and OFF markings), but gives you the general idea of which
part is being used in the circuit.
This is a wire block which is blue and comes in different wire
lengths.
They have the number , , , , , or on them
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.
To build each circuit, you have a power source block
number that needs two (2) “AA” batteries (not included
with Snap Kits
TM ).
A large clear plastic base grid is included with this kit to help
keep the circuit block together. You will see evenly spaced
posts that the different blocks snap into. You do not need this
base to build your circuits, but it does help in keeping your
circuit together neatly. 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.
The 6V bulb comes packaged separate from its socket.
Install the bulb in the lamp socket whenever that part is
used.
Place the fan on the motor whenever that part is used,
unless the project you are building says not to use it.
Note: While building the projects, be careful not to
accidentally make a direct connection across the battery
holder (a “short circuit”), as this will damage and/or quickly
drain the batteries.
