Arduino & Netduino synced communication and LCD animation

The Arduino and the Netduino are communicating over two digital IO lines. The animation is being synced over these lines. Rafel an I wanted to make the displays run. With success... but what next? Syncing both devices!

Since Rafael is developing on the Netduino platform and I am using the Arduino as platform, we had much fun putting these two devices together and let them talk to each other. This communication is used to keep the animation on both LCD displays in sync. There is a video below but it has a really bad quality. Focus your eyes on the LCD devices when watching it.

More information will follow in the next hours... ;)

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 server here and will then explain how and why the final solution looks like it is... ;)

Arduino TA07-11 5x7 Dot Matrix Display

I build a new Arduino device this weekend. I was ill and had much time chilling at home and hacked this:

Arduino TA07-11 5x7 Dot Matrix Display

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!

You could find more information and the code on my Arduino TA07-11 5x7 Dot Matrix Display page. Have fun!

WTH? My Netduino just arrived

NetduinoI got my new toy some minutes ago. A Netduino!

Netduino is an open source electronics platform using the .NET Micro Framework. The idea is taken from the Arduino platform but the difference is, that the Netduino is being programmed in .NET and it has a much more powerful 32-bit microcontroller onboard. It is an AT91SAM7X512 with the following specs:

  • Atmel 32-bit microcontroller
  • Speed: 48MHz, ARM7
  • Code Storage: 128 KB
  • RAM: 60 KB

Hopefully I could develop with the Mono project for it but at first I will do my work in a Microsoft based environment. Sounds contradictory? Yes, it is... but I want to give it a try... ;)

I am a little bit it ill at the moment but it will be a funny weekend when playing with this nice piece of hardware.

Static... forever!

I converted this site to static HTML today. The site is now being generated offline.

"wget -m" is my base tool for that... ;)

I will add some dynamic functions like comments via a cgi-bin/ directory in the future but currently I don't care about...
