Webcam motion detection coolness

A few weeks ago I had to create an innovative way to scroll in a page. I have seen tons of scrollbars in Flash and I found it hard to create something completely new. At one point I wondered if I could wire the scrollbar to a webcam using Actionscript… So I started experimenting around…

When I first started I quickly ran into a problem: How the hell do I know if anything is moving? So I actually got stuck right in the beginning.
I went on a Google trip which led me to Koen’s post about motion detection. Koen was checking all the pixels (using nested loops) to calculate color values. I figured this generated way too much overhead. There had to be a better/simpeler way.

In his post Koen mentioned an article, written by Guy Watson, concerning an other way to get motion detection going. To make things simple: Guy just takes 2 pictures - one of the previous frame, one of the current - puts them on top of eachother, and applies the difference blend mode to the upper one: Tadaaa! There we go! The ‘unchanged’ pixels are blacked out. The remaining pixels are the difference in the picture… which reflects movement. Read the rest of this entry »

Wordpress Theme SuperMini reloaded

A long time ago Smashing Magazine listed 100 of the best Wordpress themes. That list totally kicked ass to be honest. At one point I decided to restyle my poetry site. I took a look at their list and when I found the SuperMini theme, my choice was immediately made.

After I downloaded the theme I realized a lot of features were missing: No searchbox, no searchresults page, no archives, no global archives, no blogroll support, no pages support, no 404 pages and a few design flaws…

I actually went on, and built those things myself. Later on I wanted to contact the orginal author (Patrick Behrend) of the theme to send him my updates but by the time I got to send my mail, his site was down and he completely dissappeared from the web. I never received an aswer regarding the theme updates I sent him.

By now the original download isn’t even online anymore, and Smashing Magazine disabled the link to the SuperMini theme (as it is a 404). So I recently decided to finish the theme, and translate it back to English and re-publish it. I thought the initial theme was awesome, and I figured it would be cool if other people would be able to actually use the completed theme. Read the rest of this entry »

Playr 2.0 is here!

It almost took me an eternity, but at last it’s there: Playr 2.0 is ready.
Playr is a Flash Actionscript 3 class built to take the heavy lifting off your hands when building any kind of music player appliction in Flash, Flex or AIR. I put a lot of work and time in this project, and I think the result is amazing: Playr is hands down the easiest way to do so!

I’m very happy to finally release this. A lot of people helped me test it and gave me feedback.
That helped me a lot, and changed a lot of features. Special thanks to all of you!

I’ve put up a dedicated site for Playr where all of the information, code examples, downloads are gathered.
Head over there to read more about it!

Playr 2.0 is coming!

I just wanted to update you guys on how the update for the next version of Playr is progressing.

In the past week, I’ve been pretty busy adding the finishing  touches to the features and fixing the last few bugs that popped up. Most of the last-minute changes are a result of using the class in one of my own projects.

It’s then when I realized I’m missing some key features like adding the music directory, and some properties of the PlayrEvents. I also added some ear candy like fadeIn() and fadeOut() methods.

On a more functional note: I’ve abstracted the playlist to an independent class. So now you’re provided with lots and lots of ways to customize and manage your playlists.

The shuffle mode is now smart. In English that means the playlist remembers what songs have played and which ones haven’t.

Finally I’m happy to tell you guys won’t ever have to write an XML playlist file yourself. I’ve got a PHP4 and PHP5 version of PlayrDiscovr which reads a directory and returns the corresponding XML listing the tracks and their properties.
On top of that, I’ve got some help from other people (I still need to contact you guys) who are willing to help me out with building PlayrDiscover in ASP, Ruby and Python.

Even though I’m listing all of the new features, the Playr class is still the easiest way of implementing any kind of sound-feature in any Flash/Flex/AIR application. But the simplicity shouldn’t be a limitation, which it isn’t: you’re still able to build full-feature media-playing applications.

One of the little challenges I still have to tackle is the Tween problem. I’ve implemented fadeIn() and fadeOut() methods. Those methods actually tween the volume property of the Playr instance. The problem with that is when using the Playr class in a Flex project, you get a cool error message telling you it can’t import fl.transitions (which is the class package for the Tween class and the easing package).
I still haven’t figured out how to work around this problem. If any of you have any suggestion on this problem, feel free to tell me about it.

I plan on releasing Playr 2.0 in the coming week (or 2) depending on PlayrDiscovr impementations, final changes, demo’s and site development (yes, I’m building a dedicated site for Playr ) Feel free to suggest other implementations you’d like

AJAXed websites done right

Mijn beste maat, Nick, heeft zonet een van zijn coolste Javascript projecten online gepost. Het gaat om zijn Javascript class die het toelaat om een standaard (werkende) HTML site on-the-fly om te bouwen naar een full-option AJAX site.

Het idee was ooit ontstaan bij gesprekken over Flash-sites, AJAX-sites, Google-vriendelijke sites, en de snelst mogelijke en goedkoopste oplossing om deze RIA-oplossingen zo dicht mogelijk bij elkaar te brengen. Nick had de smaak te pakken en is er enkele maanden geleden in zijn vrije tijd aan begonnen. Gelukkig is hij koppig genoeg, zodat hij een paar weken geleden met een brede smile op zijn gezicht liet zijn hoe het ermee stond… Ik keek ernaar… Ik was onder de indruk… Read the rest of this entry »
