How To: Turn your iPhone into a Digital Photo Frame

Just before Christmas it's almost impossible to oversee the digital photo frames in the shops. They work like standard photo frames but allow you show slideshows of your pictures and just one.

But did you know, if you own an Apple iPhone (or iPod Touch) you already have a device which you can turn into a photo frame while you are at home? The iPhone comes with a clear, bright and not to small display which makes it perfect to display your photos. There is only one change you will have to do:

  • Just go to Settings, the General and and change the Auto-Lock setting to Never

That's it. It keeps the background light on all the time and doesn't put the phone to sleep. Now you can go to the Photos application and start a slideshow of your photos and there you have the digital photo frame. Of course you will want to put the iPhone into the dock or at least connect the cable to not use your battery.

The nice thing about using the iPhone as a photo frame is the built in internet connection. Means you are not restricted to your own photos on the phone but you can load and display content from the internet. Here are some ideas:

Of course you aren't restricted to photos at all:

  • Display the latest news by running an RSS reader.

  • Don't miss new mails coming in.

  • See world clocks from WorldClockr or countdowns from CountDownr.

This way your iPhone becomes a much better (but of course more expensive) digital photo frames than most devices you can buy today.

New Project: WorldWatchr

I just started my new WorldWatchr project (

This application makes it easy to monitor web images which are continuously updated (like web camera pictures). Now you can stay in touch with your home, famous places of the world, the current traffic conditions and much more by watching your favorite web cams. It can cycle through all your cameras and updates the images periodically.

The images don't have to be produced by web cams. You can monitor any image which is updated over time like weather radars, traffic maps and so on.

You can link from your web site to WorldWatchr so that your web cam can be easily added. Just use
with your web cam URL and an optional TITLE as parameters (make sure it's properly encoded).

WorldWatchr - iPhone version

WorldWatchr has a special iPhone version:

Please open on your iPhone and take your web cams with you.

Hint: Send your web camera URLs by email to get them easily on the phone.

Why Apple made Safari so fast

Apple claims that Safari is the fastest browser on any platform, and they seem to be right. Since I read that news I have been asking myself:

Why on earth did they put so much engineering effort into such a feature? Does anybody think Firefox, Opera or even IE are too slow? Compared to the network imposed waiting times the rendering doesn't matter. All browsers seem to be fast enough, so putting in more development time to optimize the rendering speed even further doesn't make any sense, right?

This is what I thought until I got the new iPod Touch in my hands. And now I understood. The Safari browser on the iPod (and the iPhone) is fast, by far the fasted browser I ever saw on a handheld device. I feels like a desktop browser and this must be the reason why Apple optimized Safaris rendering speed. Well done.

Firefox on Apple TV - Anybody?

For quite a while now I'm looking a for a decent surf box for my living room. I think all the Media-Center-PCs aren't good enough; they are way to big. The other option would be to use one of the new game consoles. But:

  • the Wii doesn't do HDTV (at least until now)

  • the XBox is too loud

  • the PS3 too expensive and consumes too much energy (180 Watts on standby!)

Now there is the new Apple TV box. Actually the perfect hardware for a surf box. Small, quiet and with HDTV support. Fortunately it's running a stripped down version of OSX so it should be no problem to install and run Firefox on it. OK, I can hear the question already, why not Safari? Wait a minute: an unmodified desktop browser (either Safari or Firefox or any other) will be of almost no use. In order to be a perfect surf box there have to be certain modifications:

  • Usage of the Apple Remote because nobody wants to use a mouse in the living room. Sorry Safari but I can't see the support for that (except Apple is doing it them self). It will be hard enough to come up with a good usage scheme to allow page scrolling, link following, bookmark access and so on with the limited keys of the Apple Remote.

  • Running in full screen kiosk mode and get rid of unnessary toolbars.

  • A basic onscreen keyboard will be necessary to enter a URL and fill in forms (but in the beginning a local customizable start page will do).

  • Integration into the Apple TV menu. That should be easy, because this RSS extension already did it.

So in summary Firefox seems to be the perfect browser to try because it can be customized to almost any extent, can be enhanced by a huge collection of extensions and almost all websites support it.

Is anybody working on that? Please let me know.

I added a new section to World Clockr where you can compare the Paris world clock directly with the Eiffel Tower web cam. Most interesting will be the times around sunset and sunrise, make sure you don't miss it.

If you want to have the same on your web site, just check the syndication page on how to embed a world clock into your web page.

New Project: CountDownr


Today I started my new project: CountDownr.

CountDownr is a little Ajax project which gives everybody his own collection of countdown counters. Each counter is customized to its own time and date when it goes off. There are two types of counters:

  • Counters for a specific date and time. These counters can be repeated daily, weekly, monthly or yearly which advance automatically when the alert goes off. They are perfect for reminders on single events, lunchbreaks, weekends, paying your monthly bills or birthdays and holidays.
    Example: Midnight

  • Counters which read the upcoming events from public Google Calendars. Any public calendar can be the source for a counter. It advances automatically to the next event after each alert.
    Example: Google Developer Calendar
