# binary to decimal

Hi

trying to convert a binary set of " numbers" to decimal.

The binary is to be read verticaly - when converted the numbers will
represent a "digital" time i.e. hh/mm/ss

this is the binary:

0 1 0
0 1 0 1
0 0 0 0 1
1 0 0 0 0

Can someone give me the digital numbers? - tried looking for a conversation
calculator but all i can find it a "method" showing how to do it. but it
talks about intergers, powers of 2, running and weight. When i left school
we were using an "abacus", chalk and slate.

Help will be much appreciated

cheers

Try not to make the same post 3 times within minutes. Impatience is not
a virtue.

There's an echo in here.

I got my buddy a clock a couple Christmases ago that has that arrangement
of blue LEDs and displays time with

1 = lit
0 = dark

It's a trip! And it's fun.

But the initial configuration the OP posted is [slightly] wrong, which
in 'math' we call wrong.

It is missing the 5th vertical column [for the seconds more than 15].
It should be

0 0 0
0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0

<use monospace font for columns>

so that the last 2 vertical columns on the R are seconds, the middle 2
minutes and the first two on the L hours.

Then, the bottom row would be 1, the 2nd 2, the 3rd 4, and the top 8.
The minutes and seconds need to be able to go to 00-59 and the hours
need to go 00-23

But the thinkgeek clock as depicted didn't use the most efficient binary
configuration, in terms of the number of lights, because they wanted a
column of lights for every decimal clock 'digit' or numeral space.

If they had stacked up the light columns vertically 6 high to 32 in the
hours and minutes and 5 high to 16 in the hours, they could've gotten
away with 3 less lights.

0 0
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0

<use monospace font for columns>

The thinkgeek configuration requires 20 lights, this one just needs 17.
In this config, the 3 columns are hours, minutes, seconds.

Or stated another way, you only need 6 places for binary digits to make
59, and only 5 places to make 23.

He/I meant

If they had stacked up the light columns vertically 6 high to 32 in the
/seconds/ and minutes and 5 high to 16 in the hours, they could've
gotten away with 3 less lights.

I think that's what
http://www.thinkgeek.com/homeoffice/lights/59e0/
means by *true-binary* display. The top led in each of the short columns
would not get lit.

The normal (Powers of Two) mode is what I would call binary-coded-
decimal, each column showing the binary equivalent of a decimal digit.
In a non-geek clock, each BCD digit would be normally be converted into a
7 segment LCD display looking vaguely like

- - - - - -
| | | | | | | | | | | |
- - : - - : - -
| | | | | | | | | | | |
- - - - - -

or 42 lights, even LESS efficient, but much more readable.

One could also do it in ASCII with 28 LED's, or Decimal with 28 LED's -
that's the number of LED's in a 7-segment display you would need.

http://www.wharton.co.uk/digital_clocks/401_020.htm

There is also a way to show the time/date/text with just 7 LED's, using
a swinging arm and strobing the LED's based on position so that they
appear to be a banner.

http://www.thinkgeek.com/homeoffice/lights/59ac/

Most Binary clocks, for a long time, have always done the
-8 -8
-4 44
22 22
11:11
medthod, some included seconds, but not many.
