1.3 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 (25W fixed temperature recommended) 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).

- 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 500mA

Output plug: 2.1mm pin, centre positive.

A suitable adapter is shown below:

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 the picture below. It can easily be

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

The 15pF and 33pF capacitors will be marked 15 and 33

respectively. The 100nF capacitors will be marked 104.

Q1 (IRFD220) is in a very similar package to Q2 – Q4 (EL817). You

can tell the difference, in addition to the part marking by looking at

the pins. Q1 has two pins that are actually joined at the resin body.

Q2 – Q4 have 4 separate pins.

Inductors L1 and L2 may be one of three types:

4. ASSEMBLY OF THE PCB

4.1 1mm Sockets For Nixie Tubes

There are 66 individual sockets that need to be placed. Note that

there are 2 holes per tube with NO SOCKET.

Be sure to insert the sockets from the front side of the PCB. This is

the side with substantially more white component markings on it.

Insert and solder all the sockets for each tube at a time, before

moving to the next tube location. Be sure to insert the sockets

FROM the tube side of the PCB – the side with the tube markings.

After inserting the sockets, the best way to hold all the sockets in

place whilst soldering them is to insert a tube.
