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 & R3 go.
Ensure that you put the resistors in the right place.

The power switch should be soldered into SW1 on the PCB. Make sure the slider on the switch is
hanging over the edge of the PCB, NOT facing into the middle.
The LED should be soldered into LED1 on the PCB. Make sure the shorter leg goes into the hole
closest to the flat edge on the PCB markings. The flat edge on the plastic dome should also line up
with this marking.
There is one ceramic disc capacitor which should be soldered in to C2 on the PCB. The capacitor should
be marked ‘104’. It does not matter which way around it goes
The other two capacitors are electrolytic capacitors, they are both marked 1uF. Place these two
capacitors in to the board where it is labelled C1 and C3. Make sure the device is the correct way
around. The capacitors have a ‘-’ sign marked on them which should match the same sign on the
PCB.
