How To Read The Powers of 2™" BCD Binary Clock

To read the time on The Powers of 2™" BCD Binary Clock as displayed in the accompanying photograph, evaluate each column in sequence:

1. The first column on the left ("tens of hours"): has only the bottom light is lit (value 1), so the value of this column is 1.

2.The second column from the left ("hours"): no lights are lit, so the value of this column is 0.

3.The third column from the left ("tens of minutes"): only the third light from the bottom is lit (value 4), so the value of this column is 4.

4.The fourth column from the left ("minutes"): only the fourth light from the bottom is lit (value 8), so the value of this column is 8.

5.The fifth column from the left ("tens of seconds"): the bottom light is lit (value 1), as is the light above it (value 2), so the value of this column is "1" + "2" = 3.

6.Finally, the right most column ("seconds"): the bottom light is off, but the light above it (value 2) is on, as is the light above that one (value=4), so the value of this column is "2" + "4" = 6.

So the time displayed is: 10 hours, 48 minutes and 36 seconds.
