This library Includes support for the majority of packet types, including: TX/RX, AT Command, Remote AT, I/O Samples and Modem Status. Note: This software requires API mode, by setting AP=2. If you are using Series 2 XBee, you'll need to install API Firmware with X-CTU (Series 2 are manufactured with with AT firmware), then set AP=2. This software will not work correctly with AP=1 Refer to XBeeConfiguration and WhyApiMode for more info.
How to Create a 3D Gallery of Images and Videos Russel Tarr at Classtools.net has come up with another neat tool for students. The Classtools 3D Gallery Generator enables students to create a virtual 3D gallery of images and videos. Each gallery can have up to ten images and or videos.

Kerem Erkan QR Generator This page is an online two dimensional code generator which is written in PHP. It can generate QR Code, Data Matrix, Aztec Code and Micro QR Code for the time being. Because QR Code is much more popular than the other code formats, it is separately named in the page title. If you need more information on two dimensional bar code systems, I strongly suggest that you take a look at Roger Smolski‘s comprehensive blog on QR Code and two dimensional bar codes. Using the form on this page, you can create two dimensional code images that trigger various actions on the scanner device. XBee® Wireless RF Modules XBee modules are available in a wide variety of RF frequencies used around the world. Using a single XBee design, developers can support frequencies including: 2.4 GHz902 - 928 MHz865 - 868 MHz
101 Web 2.0 Teaching Tools Online tools and resources have made it easier for teachers to instruct students, and for students to collaborate with those teachers and with other students and parents.

Uncanny valley In an experiment involving the human lookalike robot Repliee Q2 (pictured above), the uncovered robotic structure underneath Repliee, and the actual human who was the model for Repliee, the human lookalike triggered the highest level of mirror neuron activity. Etymology The concept was identified by the robotics professor Masahiro Mori as Bukimi no Tani Genshō (不気味の谷現象) in 1970. The term "uncanny valley" first appeared in the 1978 book Robots: Fact, Fiction, and Prediction, written by Jasia Reichardt. The hypothesis has been linked to Ernst Jentsch's concept of the "uncanny" identified in a 1906 essay "On the Psychology of the Uncanny". Jentsch's conception was elaborated by Sigmund Freud in a 1919 essay entitled "The Uncanny" ("Das Unheimliche"). Hypothesis This area of repulsive response aroused by a robot with appearance and motion between a "barely human" and "fully human" entity is called the uncanny valley. Theoretical basis
