Cubestormer: rubik cube solving robot

Here is a robot that can solve rubik cube in less than 12 seconds. This robot is built from lego mindstorm kits. The speed at which it solves the cube is pretty amazing. I think having 4 arms to hold and twist the cube is really smart idea that will help in solving the cube quickly overcoming the mechanical speed limitations.



I have worked with lego mindstorm kit when I was doing my masters. It was great fun. We could replace the default firmware on the controller with a firmware which can be programmed in C/C++ language. I forgot the details, but I think we used the legOS firmware and a cross compiler for esterel. It was a simple project. We did a light seeking robot and a line tracing robot. I will write about it some other time.

Tutorial to unlock 2G iphone running 3.1.2 firmware on windows (link)

Here is the link to the article that was published last week from iclarified.

I had been waiting for this article for a long time. Though apple released 3.1.2 firmware long back the windows users are not blessed with the latest version of redsnow. The mac version of pwnage came almost two months back. Here is the link if you are interested.

I am currently having unlocked 3.0 firmware. There are some connection issues and call related issues. I am not very happy with 3.0 firmware. So, I want to upgrade to 3.1.2 firmware which reportedly fixed these issues.
