1.4 SAFETY

DANGER: The clock pcb includes a switched-mode voltage booster

circuit. This generates nominally 170 Volts DC. Assembly may only be

undertaken by individuals who are suitably qualified and experienced in

electronics assembly and are familiar with safe procedures for working

with high voltages. If in doubt refer to a suitably qualified engineer

before proceeding.

The voltages generated by this circuit can give a potentially

LETHAL ELECTRIC SHOCK.

DISCLAIMER: This product is supplied as a kit of parts intended only for

suitably qualified electronic engineers who are suitably qualified and

experienced in electronics assembly and are familiar with safe

procedures for working with high voltages. The supplier his agents or

associates accept no liability for any damage injury or death arising from

the use of this kit of parts.

This is not a finished product and the person assembling the kit is

responsible for ensuring that the finished product complies with any

applicable local regulations governing electrical equipment eg. UL CE

VDE.

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.

- A small hot air gun will be needed to shrink the heat shrink tubing

over the neon lamp wires.

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 1A

Output plug: 2.1mm pin, centre positive.

A suitable adapter is shown below:

3.3 Parts list / Packing Sheet - Additional parts

• PCB

• 6 X 15mm M3 hex spacers with screws

• HV Module with male header and glue dot

• 2 X Glass neon covers

• 30cm Clear heat shrink insulation for neons

• 6 X Socket holders and 66 sockets

The resistors used in the kit are 1% tolerance metal film. They are

marked with 4 coloured bands to identify the value. However it is

sometimes unclear in which direction the bands should be read.

Therefore we recommend that the resistors be identified with a

multimeter.

Please note the fuse will look like one of the pictures below. It can

easily be confused for a capacitor. It is a self-resetting fuse.

3.4 Special Note:

Please note that several components can be possibly mounted on

either side of the PCB and white component print for the part is on

both sides of the PCB. This is to offer maxiumum flexibility of the

kit: For our clear cases most components will be soldered on the

top (tube) side of the PCB so they are visible on the finished clock.

However for the Viso case and for customers making their own

case it is possible to mount some of the taller components on the

bottom of the PCB so that the PCB can fit inside a case with the

tubes protruding. Please follow carefully the instructions. Unless

specified otherwise please solder all components on the top of the

PCB.

4. ASSEMBLY OF THE PCB

DUE TO PRODUCT DEVELOPMENT AND IMPROVEMENTS,

YOUR PCB MAY NOT LOOK EXACTLY LIKE THE ONE

PICTURED.

4.1 Assembly of the tube sockets

Remove the protective film from both sides of the six laser-cut

tube socket holders and identify the side that is engraved

‘SOCKETS THIS SIDE’.

For each socket holder you need to push in 11 socket receptacles.

Push them in from the ‘SOCKETS THIS SIDE’ side. Push them with

the 2 open jaws going in first. Look at the photo below.

Push all the sockets firmly into place until they stop. You will end

up with 6 socket assemblies. Put them to one side. Do not solder

them to the PCB yet.

4.2 Resistor Networks RN1 – RN6

Solder the 6 resistor networks on the bottom side of the PCB as

shown below. These parts are not polarized so the orientation

does not matter.
