Samsung Gravity T459 to be launched by T-Mobile on November 17th

It’s not exactly a T-Mobile G1, but T-Mobile’s side-sliding QWERTY-keyboard equipped Samsung Gravity T459 seems interesting enough, and will be launched on November 17th.

Unlike the T-Mobile G1, it will not be running on an Android-based platform, though it sure looks like it could do a redesign too. It’s not really one of Samsung’s best dressed phones, if you know what I mean.

Its features include EDGE data, a QWERTY-keyboard, a built-in 1.3 megapixel camera, microSD card slot, stereo Bluetooth and USB connectivity. It’s also myFaves capable, and supports syncing with a PC.

As mentioned earlier, it will see its official launching on November 17th, in Lime with Gray and Aqua with White variants. No word yet on its official price, though.

diy balancing robot rocks, rolls, then falls

This guy made a sweet little DIY balancing robot that balances without the help of fancy gyroscopes. It’s kind of like a poor man’s version of the Segway-esque A.M.P.bot, the main difference being that this one falls down a lot.

The robot uses a “simple switch as a sensor and stands on only two wheels with inverted pendulum mechanism. When the robot is going to fall the motor starts and moves the robot to the direction it is going to fall, so the motor torque about the center of gravity that is higher than the motor makes the robot balanced.” Check out this video to see it in action.

The maker helpfully put up a tutorial in case you’re inspired to make one of your own! Although I’m not sure why you’d do that, other than to mess with your cat or something.
