May the Force be with You
I found this in the ./images directory of hanez.org today and thought it must be online again... ;)

Time for changes...
I am restructuring this site and the server it is running on at the moment. I moved the site to a new server today. No script languages, database servers etc. anymore! Everything is being generated offline to static HTML since some days!
This website is just a mirror off what I am running on my local system. No backups of the server needed anymore, jehaaa!
The webserver underneath this website is thttpd at the moment but it is just an experiment. I am leaving the era of dynamic webpages so I don't have any need for software like Apache anymore. thttpd is great but I am missing some features. I will give lighttpd a try in the next days.
The RSS and Atom feed has been moved. Update your readers! Maybe they will come back to the old place later but at the moment I don't care.. The problem is, that I could not configure thttpd to read index.rss files like reading index.html automatically in a directory context. It is not a big problem but some more features would be great.
I will publish the state of the hanez.org server here and will then explain how and why the final solution looks like it is... ;)
Arduino TA07-11 5x7 Dot Matrix Display
I built a new Arduino device this weekend. I was ill and had much time chilling at home and hacked this:
It is a TA01-11 LED matrix from Kingbright. It was a little bit tricky to figure out how it works because it was the first matrix I played with but at the end everything worked fine... ;) Thanks to Rafael for this great hacking session!
In this Example I am using a Kingbright TA07-11 Dot Matrix LED Display using an Arduino as controller.
The code is mostly based on the DirectDriveLEDMatrix example on the Arduino playground website.
The next step will be to use a LED driver IC for keeping the usage of Arduino ouputs low.
The five Transistors are for regulating the voltage on the columns of the Display. In this circuit all LED's are getting the same voltage power of 5V.
The code looks very ugly at the moment, but I will clean it up. It is a dirty written prototype... ;)
