Build Instructions
Before you start, take a look at the Printed Circuit Board (PCB). The components go in the side with the writing on
and the solder goes on the side with the tracks and silver pads.
Start with the three resistors:
The text on the PCB shows where R1, R2 etc go.
Ensure that you put the resistors in the right place.
Solder the diode into the board where it is labelled D1. It is important that the diode is inserted the
correct way around otherwise it will not work. If you look closely at the diode, you will see that it
has a black band at one end. This should match the outline on the PCB.
Solder the two inductors into the PCB where it is labelled L1 and L2. The inductors look like the
resistor but are slightly larger. It doesn’t matter which way around the inductors go into the PCB.
Solder the two 1nF capacitors into the PCB where it is labelled C1 and C2. The capacitors can be
identified by the text ‘102’ which is written on them. It doesn’t matter which way around they are
put into the PCB.
Solder the two transistors into the PCB where it is labelled Q1 and Q2. The transistors have to be
inserted the correct way around to work. Make sure that the outline of the component matches
the outline on the PCB.

Solder the LED (Light Emitting Diode) into the PCB where it is labelled LED1. The LED has to be
inserted the correct way around to work. Make sure that the outline of the component matches the
outline on the PCB (the LED has one flat edge). Depending on your enclosure design, you may wish
to mount the LED at a specific height above the PCB or on wire leads.
Solder the PCB mount battery holder into the PCB where it is labelled BAT1. The battery holder has
to be inserted the correct way around to work. The markings on the PCB show where the ‘spring’
end of the battery holder goes.
Next connect the solar cell to the PCB. First, look at the back of the solar cell. There are markings
to show which are the ‘+’ terminals and which are the ‘-’ terminals. Now look at the PCB and you
will see that the terminals labelled ‘solar’ also have labels to indicate which is ‘+’ and which is ‘-’.
In the kit there is a bundle of wire. Use two lengths of this to connect each of the terminals on the
PCB to the corresponding terminal on the solar cell. The solar cell has terminals that have already
been tinned with solder and you will find these the easiest to solder to.
The last job is to insert the rechargeable battery (the battery holder indicates which way around the
battery goes). Before you insert the battery please go through the ‘Checking your solar light PCB’
section on the right.
