'Millennium Clock (Repost)'
1998\11\14@142936 by Ed Edmondson

I am still seeking information, code, schematic, parts list, etc., for
building a Millennium Clock.  And as previously noted it should be Y2K and Y3K
compliant, VBG.  I have been looking at all the PIC and Atmel AVR sites and
can't seem to find anyone who has tried to build one.  There are a lot of
Millennium gimmick clocks for sale but it has always been so much fun to build
it yourself.

Which PIC  would you use?  I have the following devices in hand to choose
from; 16F84, 16C63, 16C622 or 16C64.

I was thinking you could use a smart 2 X 20 or 4 X 20 LCD module with the
Hitachi controller built in?  Just wire up the data lines and you have the
display.

The timebase could be a NJR 6355 RTC chip and/or the 60 Hz line.  This way it
would run off batteries if the AC power is lost.

You could use a wall wart for the primary supply and batteries for standby
power.  Add some switches and / or buttons to set the clock with and maybe a
small piezo indicator (Beep on January 1, 2000).

The display (depending on which you use) could display the current time
(hh.mm.ss.xx) on line 1, the day (XXX), month (XXX), date (XX) and year (XXXX)
on line 2.  Line 3 could display the remaining days (xxxx), hours (xx),
minutes (xx), seconds (xx) and if you wish tenths of seconds. Line 4 could be
a message(s) of  some type.

Any comments on this DIY clock, except that it maybe finished in the year 3000
:-) since I am new at microcontrollers.  I have enough information to be
dangerous??

Ed,

I have been looking at this myself for sometime.  I plan to convert the
code for the PIC, and when I do, I will let you in on what I have.  Mind
you though, it may be a while as other duties take priority.

                                                       Regards,

                                                           Jim

Sorry, can't help with schematics, but maybe you should include an ISD
digital sound recorder chip with "Auld Lang Syne" on it which would play on
every new year <50% GRIN>

Correct me if not, but I believe, that the second millenium will end on
December 31, 2000. The third millenium will start the next day January 1,
2001. Good news, you have one more year for this project.

In a former treatise, Josef Hanzal spake thusly:

Depends on how you define "millenium". If you're the sort that argues,
"Since there was no year zero...", you'll  be a year late to the Big Party that
the rest of us (who KNOW that the millenium starts when the millenium digit
changes) will be at.

For my purposes, I shall merely map the year 1 B.C. onto Zero A.D and claim
tha there really WAS a year zero, if ya wanna be pedantic about it. :-)

I have just asked my wife and a visiting local 12 year old boy,
and both say that the new millennium starts Jan 1, 2001

Wolfgang you maybe attending a rather small celerbration !

On the contrary, I suspect that December 31st 1999 will see some of the
biggest ever new years celebrations.  Irrespective of whether the millenium
starts on 2000 or 2001, the significance for most people is the fact that
the thousands digit rolled over, an event that not many people will see
again......  Just like watching the odometer on my car roll over to zero ;o)
