2. TOOLS AND EQUIPMENT REQUIRED
2.1
Tools required to assemble the PCB.
The following tools will be required to assemble the PCB:
-
Soldering iron with a small tip (1-2 mm)
-
Wire cutters (TIP: A small pair of nail clippers works very well for this
function)
-
Wire strippers (TIP: A small pair of scissors is quite suitable)
-
Multimeter for voltage tests and for identifying the resistors.
-
Small flat screwdriver for adjusting the high voltage supply
2.2
Materials you will need.
Solder. Lead - tin solder is preferred. Lead free solder, as now required to be
used in commercial products in Europe, has a much higher melting point and can
be very hard to work with.
Desoldering wick (braid) can be useful if you accidentally create solder bridges
between adjacent solder joints.
2.3
Other items you will need.
The clock kit does not include a power adapter. This is because the kit is sold to
many countries around the world, each with very different household mains
outlet socket types. If you are using a DCF or MSF receiver avoid switching
power type supplies, as they can cause interference problems.
The type of power adapter can be obtained at very low cost. The following type
of adapter should be obtained and used with the kit:
Output 12V DC
Minimum power output capability of 500 mA
Output plug: 2.1mm pin, centre positive. A 90 degree plug is preferred if you will
use our Plexiglass case.
A suitable adapter is shown below:
