show and tell time !

[dacflyer]

ok,,, i cannot help but to show this for all to see...
since i love electronics,,,and i am a clock nut..
i found this on E-Bay..
its called the Ailen Clock..see link..<p>http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 07837&rd=1<p>i was looking to see if the big ben clock was still in there...nothing...i am in middle of making my own version...a lot simpler.. made of many 4017's and 217 leds..
anyway... just sharing

Truly unique, dacflyer, but hands on a clock are so much easier to read! Maybe it's from my time-telling training (a very long, long 'time' ago!), but even reading a digital clock requires some math to "know" what time it is, don't you think?
11:19 requires math to know its about 20 past 11. But on an analog clock, the hands position tells me that immediately. AND, how about digital 24 hour clocks? 2151 just doesn't seem like about 10 minutes to 10! My 2c.<p>

JAWAX>> ya i know...and i thank you for the help your giving me too,,,
i just love blinky flashy things !...
OOooooo SPARKLES FLASHHYYYY !!!<p>heres some more neet time pieces to boggle the mind....
binary watch.........i just might have to get this one
http://www.thinkgeek.com/gadgets/watches/6a17/<p>and binary desk clock...i am building my own..but its not micro controled... its conventional off shelf parts..

I remember when the binary clocks came out in the early 80's (or was it the late 70's?). The clock I want is even more interesting. So as long as we are showing neat clocks, how about these:<p>
http://www.amug.org/~jthomas/clockpage.html<p>I especially like the nixie wrist watch. Here is a nixie clock for your web browser. It gives the time of day in several formats and even counts down to the next leap second:<p>http://www.leapsecond.com/java/nixie.htm

awsome ! got me drooling over the watch...i love them KRUSTY brand batterys

You can then print out a sheet of the label and "roll your own" Krusty batteries.

Message to dacflyer:
Did you find any mor info about the Ben Clock?
I am in the process of putting one together and was looking for the schematics.<p>Thanks.

I worry that today's kids will not know what clockwise "means" when I tell them which way to turn something.

OOooooo SPARKLES FLASHHYYYY !!!<p>That was my lol for today. Thanks Dacflyer

I love cool clocks too, those nixie clocks rock, may have to get me one of them if I ever win the lotto. Check out the site below for more excellent clock works:<p>http://www.sonic.net/~chronart/

krazykat >> the big ben schematics wasn't really given..the guy had a artical in N&V it was a 2 part artical ,
last year i think in september / oktober
the clock was microprocessor controlled..
the clock was sold as a parts kit or a built unit
now i cannot find nothing...it was on ebay for a while..no more now...what happends if the thing goes belly up..cannot find the micro no more ??<p>this is why the one i am working on will be made with off the shelf parts.. and be a simpler clock also.. no chimes for each hr.. unless you want to design that into it later , but right now it will be a simple clock.. but simelar to the big ben,,only it will be a bigger face and more leds..<p>heres another cool clock i stumbled onto.. its on e-bay<p>http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... eName=WDVW

Speaking of clocks, especially solid state ones. I have been building them for a while. The first one I built was in the mid 70's, used RTL IC's. The counters where johnson counters and they were easy to decode with 2 input gates. This clock used incandesent lamps as a readout arranged rows of 0 thru 5 and 0 thru 9 for seconds, 0 and 1,0 thru 9 for hours. It was set up as a 24 hour clock. It had 1 thru 7 for the days of the week. It took about 5 amps at 3.6 volts to run it.
The next one was using the MM5314 clock chip by
National Semiconductor. I was able to interface a flourescent display to it. It was built in the mid 80's. It still works to this day, however it gains a little time each month. This problem was traced to the internal circuits of the clockchip when using a drive circuit from the power transformer.
The next one used the NTE equivalent of the MM5316 and used 6" high yellow 7 segement displays. My wife's favorite color was yellow and I had to buy 10 readouts to build her clock with 4 displays. It used a bank of darlington transistors to drive each segment of the displays.
The next one was built about 6 years ago. Uses a crystal timebase to drive the NTE equivalent of the MM5316. The 1 PPS output drives a divide by 3600 circuit to display GMT hours. So the display is seven segment displays that shows hours and minutes in 24 hour time and 2 digits that shows GMT time.
Just thought I would share my clock building experiences.
