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.
The suitable type of power adapter can be obtained at very low cost. The
following specification of adapter should be obtained and used with the
kit:
Output 12V DC regulated, minimum output capability of 300 mA
Output plug: 2.1mm pin, centre positive.
There is no maximum power output for the adapter as the clock only
draws what it needs.
A suitable adapter is shown below:
