Remote Controlled NXT car
Sunday, June 22nd, 2008
Juan Antonio sent me a link to this nice project, showing the NXT driving a RC car. In particular, I noticed the use of the Lattebox NXTe controller I posted about a few while ago. Hopefully more details, like the program codes, would be available.

3 joint robotic arm
Saturday, June 21st, 2008
Here’s a nice demonstration of 3 Hitechnic Gyro sensors by Ramin. Three gyros are mounted on the operator’s hand, and their reading (i.e. rotation per second) is integrated (using Runge-Kutta method) to get the absolute angle which is set to the motor’s. Very nice work! Notice there’s sometimes a delay between the operator and the robot, which is expected.
The code for this robot can be downloaded here.

NXTCam v. 2
Wednesday, June 18th, 2008Mindsensors.com announced a new version of their NXT camera sensor. The new version comes with an enclosure, and is supposed to have improved firmware, lens and power management.
I havn’t seen the new sensor in action, but I sure hope the firmware upgrade improved the usefullness of this highly desired sensor.

Monday, June 16th, 2008Michael Gasperi, whom most of you know wrote the excellent book Extreme NXT (among others), is working on a new book from NTS press called ‘LabVIEW for MINDSTORMS’. As the press release states this book would introduce LabVIEW to non-LabVIEW programmers using the NXT platform. The book covers both on-brick and direct command programming, and being the Technical Reviewer of the book - I can promise it is gonna be a GREAT book!

DDC is I2C, do you want to try?
Saturday, June 14th, 2008I learned from Lugnet about this amazing option - an I2C connection allready present in my laptop’s VGA monitor port! It appears that there exists a Display Data Channel (DDC) option in various video cards which in nothing but an I2C bus between the computer and the monitor. The author did not try DDC in Windows platforms, not because it is impossible, but he claims he doesn’t know how…
Anyone want to be first to show DDC communcation between PC and NXT? Here’s a lead:
