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. When putting this into the board, be sure to get it the right way
around. The band on the diode must match up with the band on the PCB. The diode is marked
D1.
Solder the PCB Mount Right Angled On / Off Switch into SW1 on the PCB. The row of three pins
that exit the back of the switch must be soldered but it doesn’t matter if you can’t solder the
other two pins.
There are three ceramic disc capacitors. The 100nF capacitor should be soldered into C2 on the
PCB. This capacitor has the text 104 printed on it. Then the two 220nF capacitors should be
soldered into C3 and C5 on the PCB.
Solder the LED into the PCB where it is labelled LED1. When putting it into the board,
make sure
that the ¯at edge on the LED matches the outline on the PCB.
