Last November, I went to an art gallery and came across a pretty design clock that would have found its place in my living room.

After seeing its price, I felt of passing out! When I came back to myself, I decided to build it myself (in better).

I wish to present you a small project that has occupied me lately: The reproduction of a design clock.


This clock is a square about 39cm, which can be placed on furniture or hung on a wall.

The facade consists of cleverly arranged letters that will give the time.

The principle is simple. The clock is composed of a matrix of characters that will illuminate to write the time it is. For example "it is eight to ten minutes" or "it is midnight and a half".

The time is thus given in 5-minute increments. Four luminous points at each corner of the clock will successively light up to give the hour to the minute in that slice.

So, if 3 corners are lit when the text displays "it is two hours ten", it will be understood "it is 2 hours 10 + 3 minutes".

Anyway, who cares to have the hour by the minute...

This clock is judicious because it has a brightness sensor that will adapt brightness according to the ambient light. This will allow you not to be bother by the light in the middle of the night :)

Moreover, the facade (here in rusty steel) is magnetized to the frame. It is easy to replace it with a facade with another style or a language...

Step 1: Principle

In the Spirit, there is nothing technically very complicated. A lot of LEDs are driven by a microcontroller with a time counting system and powered by 220VAC. All in a nice wooden and iron box :)

So this product should not cost the price asked by the reseller of the original model and my little geek side sees the opportunity to add many cool features like:

  • A WiFi connection for time synchronization and configuration from a web interface.
  • A matrix of RGB leds to change the color of each letter.
  • Full of fun display modes I could develop over time.

I had several objectives for this project:

  • Build a stylish and useful connected (IoT) object.
  • Bury myself in technique to avoid losing my touch.
  • Keep myself busy during the long winter evenings.

During this post, I will explain each stage of the project in order to keep track of it and to allow you to build (and to improve) the clock.

<p>This is beautiful. This will definately be on my &quot;todo&quot;list.</p><p>I need to learn more about electronics and about how to translate it in another language and still keep it working.</p><p>Thanks a lot!</p>
c'est g&eacute;nial !
<p>Bon travail!</p>
