Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP).
The boards can be built by hand or purchased preassembled; the software can be downloaded for free. The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs.
Arduino received an Honorary Mention in the Digital Communities section of the 2006 Ars Electronica Prix. The Arduino team is: Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis. Credits

Youtube in my TV with Wii
Posted: October 31, 2009 Filed under: FreeTime, ideas, multimedia | Tags: Wii, youtube, youtubetv 2 Comments »The last 2-4 years Greek houses have fast Internet connection. The prizes are tolerable and most of us realize that the Web is a service that everybody should experience and have in the everyday life. On the other hand the time someone spends in front of the television is shrinking. One argument for the former statement is the fact that the quality of the media, I can talk for the Greek TV/press only, that is being delivered via the television or the printed press is not anticipating the average viewer/reader. Most of the Greeks can talk and understand English and this important fact in conjunction with the enlargement of the new Web Media and the fast internet connections led us to solutions like youtube, vimeo and various services that provide online media.
alexa.com provides us with a list of the top visited urls as far as it regards the Greek audience. At the first place is Google, at the second Facebook and third comes youtube.com. Youtube comes third, however the 3rd place among millions of pages is a serious thing. Greeks, and most nations – a few days ago youtube.com announced that it receives 1 billion (billion with a B) request per day-, spend a serious portion of their active Internet time watching videos at youtube. This is reasonable: You had a bad day, missed a couple of hours due to traffic jam and you didn’t watch your favorite team winning the critical game? Don’t worry it is already uploaded to youtube or some other video hosting service.
Imagine that you are sitting on your sofa or watching some TV before you sleep at night and number 1 button of your remote TV control is for a hypothetical YouTube channel. Are you pressing the button or not? Most of us will prefer it. For two reasons:
- Local TV media do not invest. They do not have the power to surprise the TV viewer. They afraid to risk. They are establishment. Local media are businesses that are moving too slow. They don’t evolve. Bottom line: We are bored with the same TV shows.
- YouTube has a vast amount of videos. If you want to see a documentary for the Forbidden City because you intend to visit China, YouTube is the right place. You are one click away. Online media services like this, give you the opportunity or even the hope that you can find a response to your “media request” in no time.
No more pshycology. Nugh said. In a few bullets I will present you the way to turn your TV to a YouTube station using your Wii console.
- prerequisites: Wii Console and Wireless Internet Access. You need to make your Wii capable of connection to the Web. This is easy and you can check either your Wii manuals or numerous of web pages for step by step instructions.
- create an account at club.nintendo.com. Do it with your internet browser it is free and easy. With your club nintendo account you can access areas at their web site in order to buy games, access several channels and e-facilities. These goodies can be bought with your credit card. A short comment here: The youtube/tv service was not free about a year ago. Nintendo sold this service for a few bucks (worth spending), however it was not free. Today is free. This is correct decision and I don’t want to comment on that right now.
- From your Wii console go to the Shop Channel. This selection will connect you to Nintendo’s site and from there you will search for the Internet Channel. Confirm that you want to download it, wait a minute and an Opera browser will be installed at your Wii console for free. Nintendo will responde with “OK”.
- From the Wii Main Menu navigate to your new Internet channel and access web sites typing with Wii’s remote control your favorite URLs, at the address bar.
- In order to watch YouTube you need to type the address www.youtube.com/tv
- You can customize your preferences. It is quite easy. You can even login with your youtube account in order to watch your playlists, if any.
Those steps are adequate to bring this service at your sofa. Bottom line: Don’t forget that you just installed an Internet browser at your Wii Console. Of course you can navigate to your favorite sites, read email, update your calendar, read your feeds, send tweets via your twitter.com account.
Computer vision does magic
Posted: October 10, 2009 Filed under: ideas, multimedia | Tags: image resize, photosketch, seam carving, sketch2photo Leave a comment »I will briefly comment on two amazing videos related to computer vision and computer graphics. The work comes from Universities, ie academia, and I am pretty sure that will be included in commercial software in the near future.
Sketch2Photo is a program that takes a freehand sketch as an input and it searches for images on the internet that match the “description of the sketch”. The work is better explained at the Department of Computer Science and Technology, Tsinghua University National University of Singapore.
Look at the following image:
The sketch is the grey picture at the top right. A freehand sketch with the tag “throw frisbee” and a few others “tree”, “dog”, “frisbee” is the input to the Sketch2Photo system. The algorithm search images that match the tags and the position. This is truly amazing. Computer vision makes magic.
From the original paper: We introduce a system for progressively creating images through a simple sketching and compositing interface. A large database of over 1.5 million images is searched for matches to a user’s binary outline sketch; the results of this search can be combined interactively to synthesize the desired image. We introduce image descriptors for the task of estimating the difference between images and binary outline sketches. The compositing part is based on graph cut and Poisson blending. We demonstrate that the resulting system allows generating complex images in an intuitive way. The complete paper can be found at the ACM portal.
Quite impressive, isn’t it?
Impressive indeed. The second work is called seam carving and is related to image resizing. From the original paper:
“Traditional image resizing techniques are oblivious to the content of the image when changing its width or height. In contrast, media (i.e., image and video) retargeting take s content into account. For example, one would like to change the aspect ratio of a video without making human figures look too fat or too skinny, or change the size of an image by automatically removing “unnecessary” portions while keeping the “important” features intact. We propose a simple operator; we term seam carving to support image and video retargeting. A seam is an optimal 1D path of pixels in an image, or a 2D manifold in a video cube, going from top to bottom, or left to right. Optimality is defined by minimizing an energy function that assigns costs to pixels. We show that computing a seam reduces to a dynamic programming problem for images and a graph min-cut search for video. We demonstrate that several image and video operations, such as aspect ratio correction, size change, and object removal, can be recast as a successive operation of the seam carving operator.”
The rest of the work can be found here. Don’t miss the web site of Ariel Shamir a senior lecturer at the Efi Arazi school of Computer Science at the Interdisciplinary Center in Israel. Finally the second video follows:
Project Natal
Posted: September 28, 2009 Filed under: FreeTime, ideas, multimedia Leave a comment »The new immersive gaming system is Project Natal and it is being developed from Microsoft Corp. The ETA is 2010. A camera tracks gamers and matches their real life movements to those of an on-screen character. This tracking system is quite accurate and is based on Infrared technology. This is Microsoft’s response to Nintento’s Wii and the moto here is “You are the controller”. No more remote controllers or nunchucks. In the following video a gamer expreriences the well known “Crysis”.
Milo is a character that can recognize us, talk to us and interact with us. Our motions reflect to Milo’s face. This is an amazing video.
Your days of escaping reality are numbered…

GOM Player review || Sweet water in hell
Posted: April 4, 2009 Filed under: multimedia, Windows Software Leave a comment »Sweet water in hell. This is an amazing piece of software. It means it does what is says. You download an exe thatis not 200 megabytes, that is not pretending that is your browser that does not make pizza but is playbacks movies. Move your browser to http://www.gomlab.com/ click download get the exe. It takes seconds to save as, install etc. Open your movies/subtitles/etc and start watching your file.
There are some features to mention here: finds a codec if it is missing, plays broken avi (without knowing the index, it seems that this is a patent), it has embedded screen capture capabilities, it plays subtitles of various formats and it has all those adjust/change/modify things you can do with a player.
However what I like most is that it will make me uninstall all the crap under my Program Files that is related to movies.
Fantastic job guys.
There is a video encoder if you want to move your birthday_party.avi to youtube.com/birhtday_party.flv, however I cannot say much here. I haven’t try it.
Now let’s watch “L’Armée des Ombres”.
