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...


I have released the source code of my project "PC/SC for PHP" today.

It is an extension for PHP using pcsc-lite for smart card communication based on the PC/SC standard.

It is just an attempt to realize the idea of native and server side smart card communication within a PHP project. It could for example be useful if your web application needs access to crypto for signing, encryption etc. using a smart card as a SAM (Secure Application Module) or as a HSM (Hardware Security Module).

Have fun and please send me some comments...!
