Electrical Accessories for Dolls House/Model Railway

SORRY! THE ITEMS ON THIS PAGE ARE NO LONGER AVAILABLE


Sorry! Lots of pictures on this page. Please be patient. You really need to SEE this stuff.

Flickering Fire

£9.95

A tiny printed circuit board 12 x 20mm (smaller than a postage stamp) that flashes two lamps rapidly to simulate a coal fire or oil-burning lamp.
Choice of lamp colour and flicker speed for various applications, suggested as follows:

The lighting effect is very dependent on your choice of translucent film and the distance of the bulbs from the film. You can use plain white paper, coloured toffee wrappers, tisue paper, greaseproof paper or our own V-CG3300 heat-resistant plastic film (safer). The effect can further be enhanced by using crumpled aluminium cooking foil as a reflector or by using glass or plastic beads in front of the bulbs to act as light diffusers. Have fun experimenting!

Runs off 12 volt regulated dc supply (see H02-7343) or battery (see below).
IMPORTANT
- Many power supplies marked "12 volt" actually give up to 20 volts!
If you use one of these, please connect another miniature 12 volt bulb in series with the red wire to protect the unit.

Doorbell chime

DOORBELL CHIME HK00245 £21.50
A small printed circuit board that produces a doorbell chime electronically into a tiny earpiece. This acts as a loudspeaker to produce a sound that is suitable for a 12th scale Dolls' House. (You can drive a loudspeaker if you want to wake up the neighbours!) Chimes are adjustable so you can have one, two or three chimes after each push.
Runs off 12 volt dc supply. Kit requires soldering skills but my 16 year-old son managed it without problems! (If you want him to build it for you it will cost an extra £10 !!) Illustrated half full size.

BURGLAR ALARM!

BA0001 £29.95

Dolls' House modern Burglar Alarm system comprising one alarm box with blue flashing light and one Siren Box. Both boxes require a single 12v regulated d.c. power supply. The alarm box can be painted (red or yellow for example) and appropriate wording can be added by hand painting or by letter transfers. It measures 37 x 25mm plus 8mm fixing lugs (which can be cut off if not required).

Door sensors and wiring will be made available soon.

Magnetic switch

Shown slightly larger than true size is a magnetic switch 15x3x4mm and a tiny bar magnet 13x3x2mm. The switch turns ON if the magnet is less than 5mm away from it. Suitable for use with above alarm system or for controlling items such as lights without the need for a mechanical switch. Example: The magnet can be glued into the edge of a door or window and the magnetic switch can be mounted on or in the adjacent wall. Used in conjunction with BA0001, the alarm will sound if the door is opened.

Magnetic switch F732-011 price £2.95
Bar magnet F423-117 price £1.25

Versatile Switch Box for Dolls House or Model Railway (d.c. low voltage)

Until now, to operate your dolls' house lights you had two choices: heave the house forward, reach round the back and operate slide switches in a "pot luck" fashion or buy and fit an elegant (but expensive) remote control system with battery-powered handset.

Now there is an alternative: SatCure supply a simple, low cost kit from which you can build a switching box to control your lights. The kit includes a plastic box, six miniature toggle switches, six Light Emitting diodes, resistors and an umbilical cord to connect it to the lighting circuit.

The end result is a small box measuring just 76 x 57 x 25mm (3" x 2.25" x 1") with six switches and LEDs that light when a switch is "on". The umbilical cord is an unobtrusive white cable 5mm thick and 1 metre long. The combination can easily be hidden away when not in use or screwed firmly to a surface.

Tools needed

You will need a soldering iron, fine-tip pliers, wire cutters, a drill and a size #1 "Pozidriv" screwdriver. An 8mm spanner makes it easy to tighten the nuts on the toggle switches, but you can use pliers if necessary.
Suitable drill bits and solder are supplied.

£19.95 (or £29.95 ready built)

Not suitable for 230 volt mains


Wire

IMPORTANT! The following wire and strip must NOT be used for 230 volt mains power connections.


Silk Flex !
Dolls' house electrical cord has never accurately been represented in 1/12 scale - until now!

Remember those pre- 1950s mains cords on table lamps, standard lamps, the first electric irons, "wireless" radios and even telephones? They all used rubber-insulated twin flex that was cotton-covered and often a light brown colour.

That classic twin flex was 6mm in width, which translates to just 0.5 millimetres in 1/12 scale. But what do we use? White plastic-covered "hook-up" wire at least 2 millimetres in width if we are lucky! Such stuff may be appropriate for a child's dolls' house but is hardly representative of what we want to achieve in a real miniature.

Help is at hand.
A new flex is available which is truly representative of the style and scale.

Silk Flex uses two conductors, each made of no less than 24 copper strands thinner than a human hair and bound together with a covering of fine silk imported from Japan. The colour is a pinkish-brown but, if this is unsuitable for a specific application, the silk can be dyed.

Silk Flex is available exclusively from SatCure. It must be stressed that Silk Flex is specifically intended for the perfectionist as it is really too delicate for everyday play by children. However, it is perfectly capable of handling electric current of 1 Amp at 12 volts; more than adequate for several bulbs. It is available with a suitable two-pin plug fitted to one or both ends. Sub-miniature matching sockets are also available in either two-pin or three-pin style.

LTZ001 Black two-pin plug with light brown Silk Flex approx. 200mm long to suit pre 1960s electrical appliances, lamps etc. Plug pins are on 2.5mm centres (= 1.2 inches to scale).

Fits into socket F177-128 or F103-963.

Silk flex is silk-covered and extremely thin for accurate scale representation.
It contains 24 flexible copper wires, each no thicker than a human hair!

Silk Flex twisted twin 200mm with one plug £2.95
Silk Flex
twisted twin 200mm* with plug each end £3.95
*Shorter length can be supplied on request.

Silk Flex (single conductor not twin) sold by the metre at £2.00

Enamelled Copper Wire

26 standard wire guage - that's thin! This wire is insulated with enamel so you can safely twist two strands together to make twin. Suitable for carrying up to 1 Amp. Thin enough to hide in a knife groove behind wallpaper. Thin enough to pass through the smallest hole you can drill.

Available only on 50 gramme bobbins for £1.25

Electric "Skirting board" material in strips 8mm wide x 1.6mm thick.
Each strip is clad on one side with two separate copper conductors which allows you to fit electric plug sockets.
You can cut this, sand it, paint it, fit sockets, solder wires to the end and glue it to the walls!
Price to be announced but expect less than £5.00 per 300mm strip.
