Assembly:
The first step is to sort the parts into groups of similar types. Doing this now will save
time later.
Print the placement diagram below for easy reference. Experienced builders will need
little more than this diagram.
Part locations are color coded using the resistor color code to indicate the zero multiplier
of the part value to be placed there. Since several values use the same zero multiplier,
pay attention to the most significant digits.
