Recently bought the AVR Raven 2.4 GHz Evaluation Kit by Atmel. A development Kit for 802.15.4, Zigbee and 6LoWPAN networks. I contains one USB dongle which is basically meant to hook up your computer to one of the mentioned networked and two AVR Raven boards. They are battery powered have a 2.4 transceiver, display, small joystick, temperature sensor JTAG and ISP for the start. Of course there are also some IOs to connect external sensors. I found this hardware having a look at the IPv6 enabled contiki OS. I think I will spend some time with this hardware exploring sensor network technology 🙂 By the way, I think this development kit is pretty cheap. You can get all the stuff for less than 120 EUR!

During the upcoming weekend (17.07. – 19.07.2009) the Chaos BBQ Weekend will take place in Dortmund, Germany, old Europe (N51°31’39.4″ E7°27’53.8″). There will be some Workshops and Lectures and of course there will be a lot of meat (vegi food as well).
In case you need a place for sleeping, don’t worry there will be room for everyone!

See you next weekend!

Hi there, it is getting time for the annual Chaos Communication Congress in Berlin, Germany, Old Europe. This time there are many speeches about mobile device security and GSM networks, check out the “Fahrplan”.
I hope to meet some old friends and find some interesting new people. And by the way: Happy Christmas!

A few month ago a paper was released which described how to break the Crypto1 algorithm of the Mifare Classic cards. Now the implementation has been released. The files with the source code have all in all only 611 LOC. Not so much…

I unplugged my modem last week before I went to Dortmund for some days and plugged it back in last Sunday when I came back. Since then my DSL broadband access is pretty slow. Like 1 Mbit/s downstream, should be around 16 Mbit/s. Therefore I messed a little bit around with my configuration and found out that my DSL Modem – Siemens C2-010-I, is actually Viking II Plus and not a modem but a moden/router/bridge. My provider configured the Viking as a bridge, therefore it looked like a usual DSL modem.
