What is it and how it works?

Binary clock is just a regular clock but instead of using decimal numbers it uses binary. In other words instead of numbers from 0 to 9 it uses only 0 and 1 to represent time! Well.. in fact it doesn't use numbers at all. How is it possible? Let's have a look.

The hour presented below is: 12:42:57

12:42:57

How do we know that? It's simple, but requires couple minutes of practice. Every line of diodes represents  respectively: hour, minute, and second. If the diode is on, it means that there is 1 on that position in binary number. If the diode is off, there is a zero. So for example second line can be represented as a: 101010 in binary system, what represents 42 in decimal. So here is how we calculate it (you can practice in the next section):

Hour
Binary representation 0 0 0 1 1 0 0
Multiplayer
64 32 16 8 4 2 1
Product 0 0 0 8 4 0 0
Result 8 + 4 =12

Minute
Binary representation 1 0 1 0 1 0
Multiplayer
32 16 8 4 2 1
Product 32 0 8 0 2 0
Result 32 + 8 + 2 = 42

Second
Binary representation 1 1 1 0 0 1
Multiplayer
32 16 8 4 2 1
Product 32 16 8 0 0 1
Result 32 + 16 + 8 + 1 = 57

Practice section

Read the number from "binary diodes" and type the decimal value in a text box. After that click reset, to get a new, random value of binary number.

How to use it?

You can use it in full screen mode, or embed it on your Home Screen as a Widget.

  1. Full Screen mode, that works both in Portrait and Landscape directions (see screen above)
  2. As a Widget on your Home Screen:
