The Atomic Timekeeping Podcast

Following a long delay, I have produced a new episode. This time I'm talking about Apple's iPad. Like most computers, it doesn't keep time very well on its own. However, believe it or not, you can have atomic timekeeping on an iPad! You just have to know what apps to use. And that's what I want to tell you about.(Click on any image for a larger version.)First and foremost, if you have an iPhone, an iPod Touch or an iPad, you must get this free clock app from Emerald Time...Apple's iTunes Store link to view and/or download this free appCheck out their web site for this explanation of their free Emerald Time App.NEXT,If you want to spend a mere 99 cents and get a really pretty Observatory App, also from Emerald Time, well, check this out...Apple's iTunes Store link to view and/or download Emerald ObservatoryAgain, check out their official web site for more information about this app. (Please note that the Emerald Observatory is only available for the iPad.)But wait! There's more. For another mere 99 cents you can enjoy the wonderful World Clock Pro HD. Check out these screen shots...Here is the link to the Apple iTunes App Store listing of this beautiful app.One of the great things about this app is that it will work with the iPhone, iPod Touch and the iPad. So reach deep into your piggy bank and let that 99 cents do something beautiful to your portable device.And then there are some other, free apps to consider. For example, Here's the free version of a sunrise/sunset database. It can automatically detect where you are and then tell you the sunrise and sunset times for that location.And here are the links to some other FREE apps that I mentioned in this episode... The Wink Alarm Clock for iPadThe Dali Clock for iPad, iPhone and iPod TouchText Time for iPad, iPhone and iPod Touch But... enough with the blog text.

I'm back! This time I'll talk a little about the newest offerings I've seen at Wal-Mart but then I'll also tell you about the HD radio receiver I recently installed in my car. This thing can set itself to the "correct" time provided by broadcasters... or can it? Learn more by listening.By the way, did you know that James Cameron has given us a new, out-of-this-world way to keep time?

It's a special, video edition of the Atomic Timekeeping Podcast and, this time, I'm going to show you how to use an "Atomix" clock.Download the episode at the link below:AtomixDemo.m4v...or enjoy the YouTube version...Subscribe to the Podcast in iTunes

You can find "Atomix" radio controlled clock movements from Klockit at this place...http://www.klockit.com/products/dept-77__sku-AAAAH.html...and if you want to see the movement which uses three AA batteries instead of just one, check it out here...http://www.klockit.com/products/dept-77__sku-Atomic_Clock_Movement_Battery_Pack.htmlAnd now, a quick illustration to show how batteries can be arranged in "parallel" or in "series."When batteries are wired in "parallel," as in the example above, the voltage remains the same but each individual battery is drained less than if you only used one.When batteries are wired in "series," as in the example above, the voltage of each battery adds to the entire voltage of the circuit. So three batteries together will produce three times the voltage.Anyhow, download episode 22 of this podcast right here...AtomicPodcast22.mp3(Running Time 27:59)Subscribe to the Podcast in iTunes

Sorry about missing my last couple of deadlines, but here's a new episode...Download this podcast here...AtomicPodcast21.mp3(Running Time 31:33)Subscribe to the Podcast in iTunes

In this episode, I talk about the amazing gadget which was mysteriously preventing my radio controlled clocks from receiving WWVB.

First of all, I spent a little time in this podcast talking about my new, electric lawn mower. It's this Craftsman electric mower. Then I spent the bulk of this podcast episode talking about radio controlled wrist watches. Check out some links to..Casio WatchesArcron WatchesOceanus WatchesJunghans Watches...and more watchesAnd here are three radio controlled wrist watches from my personal collection. First, the Arcron-Zeit Digital Sports Watch......and the next watch is my first Casio Waveceptor Watch.And the next one is my "Tough Solar" Waveceptor watch, which I've actually had since 2006.So, have some fun with radio controlled watches!Download Episode 19 here...AtomicPodcast19.mp3(Running time 46:42)Subscribe to the Podcast in iTunes

A few things this time around: First, if you're interested in radio controlled clock products from Skyscan, Here's a link to their company web site...http://skyscan.info/content/index.phpThat link will also contain links to contact information and product manuals for both current and discontinued products.Meanwhile here's a nice place to look up sunrise and sunset times for your favorite U.S. cities.http://www.sunrisesunset.com/custom_srss_calendar.aspAnd here's a math quiz for you. If I say, "This hamburger costs five times more than a sandwich," how do you express that as a mathematical equation?Let's see... if the sandwich is $1 then let's say that "n=1." Now, "five times more" would be something like this: "n + 5n," right? So then "five times more" is the same as "six times the original number."n+5n=6n. So if the sandwich is $1 then the hamuger is $6. Not five but SIX!Now, if I say that a used computer costs three times less than a new computer, how do you express that as a mathematical equation?. I'm not even going to try.So, download my podcast episode here...AtomicPodcast18.mp3(Running Time 30:29)Subscribe to the Podcast in iTunes

In this episode, I refer to a listener's email regarding public tours of the U.S. Naval Observatory's facility in Washington, DC. If you'd like to request a spot in an upcoming tour, here's a link with more information.http://www.usno.navy.mil/USNO/tours-events/tour-information/tour-information-for-usno-washington-dcAlso, I have a follow-up to the last episode with my post-NAB report on just a couple of things I saw in Las Vegas. Here's some information on NHK's Super Hi-Vision...http://www.nhk.or.jp/digital/en/superhivision/index.html...and there's even a Wikipedia article about this stuff...http://en.wikipedia.org/wiki/Super_Hi-VisionDownload the newest episode of my podcast here...AtomicPodcast17.mp3(Running Time 33:20)Subscribe to the Podcast in iTunes

In this episode, I'll talk a little about the upcoming National Association of Broadcasters (NAB) Show in Las Vegas. And, by the time I make the next episode, I will have gone to this convention and I can give you a post-convention report.Meanwhile, I'll show you a picture of something I saw last year at this event.So, download my newest episode right here...AtomicPodcast16.mp3(Running Time 36:06)Subscribe to the Podcast in iTunes

This time, it's a special video podcast. And I wanted to tell you about a style of clock which I've enjoyed for the past 30 years... the Ball Clock!Download my video podcast episode here...PodcastEpisode15...or watch the YouTube version right here on this browser.Just a little note... I was going to ramble on for a couple more minutes in my narration of this video. But then I realized that there's a 10-minute limit for YouTube videos and I wanted to make this a YouTube-friendly production. So I cut out a few superfluous details. For example, when I was a teenager I actually conditioned myself to sleep through the night with one of these noisy ball clocks running all night long in my bedroom. I wonder if I could do that again now. Hmmm.Subscribe to the Podcast in iTunes

This time, I'll talk about how difficult it is to set your own, personal, real atomic clock to "the correct time." Taking "lag time" into account, this could be a real problem. For most of us, a "radio controlled" clock is good enough but for some people, nothing is sufficient short of owning a real atomic clock. Some of these people call themselves "Time Nuts," and here are some links that will lead you to them...http://www.leapsecond.com/A link to the Time-Nuts mailing list sign-up pageSomeone's idea of a "real" atomic clock wristwatchHow to turn a family campout into a practical demonstration of Einstein's general theory of relativity.Meanwhile, feel free to download my newest podcast episode right here...AtomicPodcast14.mp3(Running time 29:17)Subscribe to the Podcast in iTunes

Believe it or not, it's almost time to go back to Daylight Saving Time here in the United States. (I'm getting tired of Daylight Saving Time.) Apart from my annual whining about the month of February in general (which just isn't my favorite month), I do have a few useful things to share in this podcast episode. And, for those of you who are interested, please watch three, one-hour shows about the scientific concepts of "time" on "The Science Channel" on the evening of Sunday, March 1, 2009. Check your local listings for Earth Time, Cosmic Time and a program called What Time Is It?.Also in this podcast episode, I wonder why an AM/FM "Clock Radio" alarm clock with atomic timekeeping is either rare, expensive or unreliable. But here are a few links you can try...http://www.ccrane.com/radios/am-fm-radios/sangean-rcr-3-digital-atomic-clock-radio.aspxhttp://wize.com/clock-radios/t45312-atomichttp://www.radiocontrolledclock.com/stsmmuclwiam.htmlhttp://www.radiocontrolledclock.com/saatra.htmlDownload my podcast episode here...AtomicPodcast13.mp3(Running Time 34:37)Subscribe to the Podcast in iTunes

Warning! This episode contains audio test tones. I'll explain why I'm playing the test tones but, in the meantime, make sure you're not listening to this episode at high volume settings. If it's too loud, those test tones might be a little bit too surprising to your ears.So, yes, I'm talking about audio in this episode and how it relates to "Time Frequency." Time Frequency is one of the four major things that are measured by those top-level scientists at the National Institute of Standards and Technology. (It'll make more sense if you just listen to the episode.)Also in this episode, I share a very nice email from Alan in the UK. Here's a link to his blog.http://www.masterclock.co.uk/So, that's all for now. Enjoy the podcast!Download Episode 12 here...AtomicPodcast12.mp3(Running Time 27:25)Subscribe to the Podcast in iTunes

On a personal level, it has been a very busy couple of weeks. So I'm posting just a brief podcast this time around. It's a quick follow-up to the last episode. Now that we've all experienced a Leap Second together, I'll add just a few more thoughts about it. Also, I'll play the audio of what happened on WWV when the Leap Second was added at the end of 2008.Download the episode here...AtomicPodcast10.mp3(Running time 11:29)Subscribe to the Podcast in iTunes

It's time to talk about the Leap Second. Yes, there's a Leap Second in just a few hours from now (as I post this podcast). What's a Leap Second? Why do we have them?

Welcome to episode 5, my special episode about Daylight Saving Time. Download the episode here...AtomicPodcast05.mp3Running time: 36:34, File Size: 16.8 mb, Monophonic.Just a few notes:Remember that the most proper way to refer to Daylight Saving Time is just that. It is not "Daylight Savings Time" nor "Daylight Saving's Time," although many folks probably refer to it by those variations.For more about Daylight Saving Time, try these links...The National Institute of Standards and Technology page about Daylight Saving Time. Short and to the point.The Wikipedia article about Daylight Saving Time. Not as short nor to the point, but if you want a lot of information, try it out.Another spin on Daylight Saving Time from a California government-run web site.A Help page from Microsoft to assist Windows users to make sure their systems are ready to make the proper changes for Daylight Saving Time.This is an activist-type web page proposing a permanent end to Daylight Saving Time. Furthermore, they have a very interesting idea about changing the Time Zone layout of the Continental United States. I'm not saying that this is the best thing to do. I just think it's interesting and I'd never heard of this idea before seeing this web site.Remember these official show notes at http://atomicelmer.blogspot.com and you can expect at least two more episodes of the Atomic Timekeeping Podcast in November.
