Binary Analog Clock
November 29, 2006 on 5:12 pm | In Tech |The last place I moved into had a clock hanging on the wall, didn’t ever pay much attention to it since it was in an unnoticeable place in the kitchen. When I moved out I took it with me and had plans to make it into something more interesting since it was as plain as clocks come.
I put this background on it that turns it into a binary clock. Black is low, white is high. Read it by seeing if the blocks the hands intersect are high or low (the minute hand isn’t quite long enough and the hour hand is a bit too long). It’s read from the outside to inside. The inner 4 rings correspond to the hours and the 6 rings past those are for minutes. This clock is a bit different since it counts from 0 to 11 instead of 1 to 12.
In this picture (it’s not upright) the hour hand is over black, white, white, black. Which corresponds to 0110 in binary equals 6 hours. The minute hand is over black, white, black, white, white, white. Equivalent to 111010 binary = 32 + 16 + 8 + 2 decimal = 58. So the time is 6:58.

That’s fantastically geeky. Luckily, for mathematically-challenged folks like me, it can also be read like a “normal” clock.

This officially makes you the king of geekdom. :p

I’m a bit curious.
For the hour hand you appear to be saying black = 1 and white = 0. But for the minute hand you seem to say black = 0 and white = 1. I’m not sure I see the reason for this reversal since the digits for the mintues and hours don’t overlap.
Also although I might have made a couple errors if you consider the first 4 rings to be the hours than depending if you start from the inside or the outside you get (counting counter clockwise)
4,5,6,7,1,9,10,11,10,13,14,15
or
2,8,6,12,8,9,5,13,3,11,7,15
However, if you take white = 1 and black = 0 and have the inside digit as the highest than you get the
0,1,2,3,4,5,6,7,8,9,10,11
you were talking about. In this case the clock is both right side up and moving clockwise,
As well the time is now 0110 = 6 (1001 would be 9). I haven’t looked at the minute hands though but a quick glance suggests they are white = 1 and black = 0 though and the clock needs to be rotated about 3 mins clockwise to be fully upright.

Hrm, though if it is 6 and clockwise than the hour hand has way too far to move to reach 7 before the minute hand reaches 00.

What?

Ok there seems to be some confusion…
White is high! Like I said in the writeup.
for those not in the know:
high is to low as
1 is to 0 and
on is to off and
5V is to 0V and
white is to black
eh? get it?
In the picture, the whole clock needs to be rotated about 3 mins clockwise to be upright as Aaron stated. Also for the picture the hands weren’t calibrated yet (they are now), ie when the minute hand and hour hand are overlapping they weren’t centered over 12.
