Mesmerise your kids by turning their bedroom dimmer switch into an interactive story.

Here’s how it works:

With the lights on, a cardboard dial displays a picturesque daytime scene. As the lights are dimmed, the sun in the picture begins to set, until the picture reveals a night sky with moon and stars!

Step by step guide

If you’d like to make your own ‘dimmer dial’ follow the instructions below. First, let’s take a look at the approach as a whole…

It’s simple, really… just a circular dial and a cover all made from cardboard.

Prepare materials

Cut two discs from corrugated cardboard, one 94mm and the other 98mm in diameter (1). In the centre of the smaller disc (Disc 2) cut out a hole, it must be small enough to fit tightly over the dimmer switch knob.

Take the other disc (Disc 1) and use a craft knife to cut out a large ‘pie shaped’ hole, use the measurements shown (2).

Cut two strips 320mm x 27mm from thick card (210gsm) and join them end on end using glue - this is the side strip (3).

Make the cover

Apply glue along the edge of Disc 1 and attach the side strip (4).

Print the Disc 1 artwork onto card, if you can’t print onto card print onto paper and mount the paper onto card (5). Trim around the artwork and glue it onto the front of Disc 1 (6).

Print out Disc 2 artwork onto paper or card (7). Cut it out (including the hole) and then glue or spray mount it onto Disc 2 (8).

Cut out two ‘tabs’ from the thick card, fold them in half and glue them to the top and bottom of the cover (9).

Assemble it

Turn the light on and push Disc 2 onto the dimmer knob, sun at the top (10). Place the cover on top, attaching it to the wall with tape or poster putty (11).

Operate it

That’s it, just dim the lights (12) and watch the moon appear (13).


  • Rotary dimmer switch!
  • Thick and thin card
  • Paper glue
  • Craft knife and scissors
  • Pencil, ruler and eraser
  • Colouring pens or paints

What will I learn?

1) Moving objects can be hi-jacked in order to harness the movement in other more unexpected ways.

2) Storytelling, even something as simple as Day and Night, can make a project far mor compelling.

3) Even obscure objects, such as a rotary dimmer switch, can be used in very creative ways.

Give it your own twist

Not everyone will have a dimmer switch, so try picking something else to transform. Remember, the weirder it is the more imaginative you will have to be - so don’t just choose a cardboard box!
