Update
The NXT Shield is for sale in our shop: http://shop.tkjelectronics.dk/product_info.php?products_id=29. A easy to use library is also provided: https://github.com/TKJElectronics/NXTShield.
Three examples that demonstrates reading the encoders, turning the motors and using the ultrasonic sensor is found in the library as well: https://github.com/TKJElectronics/NXTShield/tree/master/examples.

More pictures of the NXT Shield can be found at the following blog post: http://blog.tkjelectronics.dk/2012/04/nxt-shield-library/.

Instead of using the shield with an Arduino, one of our customers decided to hook it up to an STM32 processor to control his robot. He described his development and findings on his blog: https://www.embedded.com/design/programming-languages-and-tools/4458801/2/Making-robots-with-Ada—Part-2—Driving-the-motors
Please note however that his code is written in the Ada language and not C/C++!

I finally made a new version of my NXT Shield. The big news is that it now supports the Lego Ultrasonic Sensor and it has NXT Compatible Sockets from mindsensors.

About a month ago Texas Instruments started their so called TI Deals – “A cool new way to get discounted tools and kits from Texas Instruments”
The service is an advertising stunt by Texas Instruments which lowers the price of some of their development tools in a specific period.

The first product to be lowered in price were their EZ430-Chronos watch. A watch with their CC430 MCU inside with wireless connectivity.

The regular price for the watch was $49.00, though as it being the first product in their new “TI Deals”, the product were sold for $24.50 – 50% off! Including free shipping.
An extremely cheap price for a good looking watch (maybe a bit big) with developer possibilities. So I decided to get myself one – and luckily for me I ordered one in time, as they went out of stock pretty fast!
