Here's a simple yet elegant WALL CLOCK made just out of cardboard and a couple of L.E.D.s!  And what more!...it doubles as a NIGHT LIGHT !!!

To see the time at night is no longer a problem!!!!....

MY MOTIVATION came from the following instructables :-
http://www.instructables.com/id/LED-CLOCK-cum-NIGHT-LAMP/
http://www.instructables.com/id/Paper-mache-clock-face/
http://www.instructables.com/id/Glass-Clock-with-LED-backlight/

Step 1: Materials & Tools List

MATERIALS NEEDED:
1) Cardboard  (a lots of it!).

2) Black Sheet (of size lager than the diameter + twice the width of the clock you plan to make!)  (I took 36cm in diameter! ).

3) A Plain Sheet (A4 size).

4) Clock Mechanism with Clock Hands (I salvaged it from an old clock!).

5) L.E.D.s - 15 of them. (mine were 8mm straw hat LEDs with wide viewing angle.)

6) RED & GREEN Marker pens.

7) Fast drying glue / superglue (I used quickfix)

8) Wire.

9) Electrical Grade Tape.

10) Fevicol (or any adhesive for the paper-mache).

11) A power supply for the LEDs (I used an old mobile charging adaptor).

12) resistor(s) (according to your power supply and LEDs you are using----I've put a link to the resistance calculator!).

13) A two way switch (optional).

TOOLS NEEDED:
1) Soldering Iron with Solder (optional).

2) A pair of Scissors (optional).

3) A Cutter Knife.

4) A Compass with Pencil for marking purposes


waw........! nice explanation ........... ........thanks for ..............it......................... I am very happy that you did not ignore my question.............................! ............................................................................but ....I thought you would ignore my question....................because you are more intelligent and more qualified then me..............! but I was wrong....................................! you are not only a good teacher but also a good human...........................................................................................thanks ...........sir..................................................
Oh!..I'm not habitual of digesting that much sugar in a single go!!. :P <br> <br>but thanks!!!. :D
haha most epic reply seen on instructables :D
you should post any new project .............! I shall wait your new project..............................! ................I hope you will do it soon................
yup!...It's coming soon!. :D
it's looking very nice..................! but I want to know that why does A simple pn-juction diode not emit of light as LED, because LED is also a pn-juction diode as a simple diode................................... ?
Because when an electron crosses the PN junction and falls into a hole, it emits a photon. The frequency depends on the energy, which is determined by the forward bias voltage. That is why a red LED requires more voltage than an IR LED, and less than a green LED.<br> <br> So a regular diode with a forward drop of about 0.7V is emitting infrared (IR) light. However, most of the photons are reabsorbed in the semiconductor body or stopped by an opaque case. An LED is a special diode doped for a higher voltage and constructed to let as many of the photons out as possible, set in a reflector and usually with a lens cast into the plastic case.<br> <br> ....No, I didn't typed it all!!!..... :P<br> just googled it!!... :P<br> <br> Hopes that answers your question!!!.... If not, well, then post it <a href="http://www.instructables.com/tag/type-question/" rel="nofollow">here</a>.... you'll surely get some amazing answers!!!.... :D
Very cool! How well can you see the hands of the clock at night?
<strong>Thanks a lot SelkeyMoonbeam!!!.... &nbsp;:D</strong><br> <br> Well, the hands are <strong>completely visible</strong> at night with no problems.....though, the visibility would have<strong> increased had&nbsp;I&nbsp;chrome plated the hands and/or used four outer LEDs instead of three</strong>.....though&nbsp;I&nbsp;didn't have a chrome spray paint bottle at hand and using four LEDs would have increased the night light's intensity to an uncomfortable level (as per bed's position)......so , this one just works good for me.... :D
