Different digital clocks
(with 24-hour-display)

Digital clocks can be designed in a variety of ways. They generally consist of four digits: two for the hours and two for the minutes. Digital clocks with a second display have two additional digits for the seconds.

Depending on the clock's orientation, the blocks for hours, minutes, and seconds are arranged differently. On horizontal clocks, the blocks are placed side by side, and a separator, usually a colon, is displayed between the blocks for hours, minutes, and seconds.

In vertical clocks, the blocks are usually arranged one below the other, and there is no separator needet. The numbers are traditionally displayed using a seven-segment display or, in more modern devices, using normal characters for the numbers.

⋮⋮   Braille clock   ⋮⋮

In Braille clocks, the numbers are represented by Braille characters. Not all clocks with dots are true Braille clocks. And blind people can also use other clocks as watches for the blind.

On the page Braille watches you will also find information about watches for the blind.

⋮⋮⋮   Fakoo clock   ⋮⋮⋮

Fakoo clocks use a matrix of 3 by 3 dots for each digit and represent the digits as defined Fakoo characters.

From the page Fakoo clocks you will find information and illustrations of the various watch variants.

⊠   Quadoo clock   ⊠

In Quadoo watches, the numerals are formed by Quadoo characters. These characters can be represented using a matrix of at least 5 by 5 dots or by lines.

On the page Quadoo you can find more information about the Quadoo alphabet.

⊟   Siekoo clock   ⊟

A special type of seven-segment clock is the Siekoo clock, in which the separators and possibly the abbreviated day of the week are displayed in characters of the Siekoo alphabet.

This allows the display to be created exclusively using seven-segment elements, without the need for additional elements such as dots or 14-segment elements. Nevertheless, all characters and numbers remain unmistakable!

⦁⚊   Morse clock   ⚊⦁

The special feature of my Morse code clock is that the digits are represented by five dots or dashes arranged one above the other. This is the only way to display the digits acceptably next to each other, as otherwise the Morse numbers would be too long.

On the page Morse you can find more information about the Morse alphabet.

▢ Four-Segment clock ▢

by Alexander Fakoó

Even with only 4 segments, the time can be displayed in such a way that the numbers have a certain recognition value.

The current time according to the four-dot system, which has nothing to do with Braille.

The time is calculated as follows (hours above, minutes below):

A popular way to represent time is binary code. The luminous dots have different values that must be added together. The values correspond to the power of 2 (2⁰=1, 2¹=2, 2²=4, 2³=8, 2⁴=16 and so on), usually starting with the lowest values at the bottom.

Addition is the secret of binary or dual clocks
