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 to trim the excess component leads after soldering.
(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.
- For the RGB LED tube lighting, a small hot air gun will be needed to
shrink the heat shrink tubing over the LEDs to form the light guides. A
small hair dryer may work for this.
2.2 Materials you will need.
Solder – lead / tin solder is highly recommended. USE LEAD/ TIN
SOLDER!.
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.
The following type of adapter should be obtained and used with the kit:
Output 12V DC regulated, minimum power output capability of 500 mA
Output plug: 2.1mm pin, centre positive.
A suitable adapter is shown below:
