Maybe you are very familiar with the seeeduino stalker series, or maybe you are totally new to this feature rich Wireless Sensor Network Node. No matter what situation you are in, if you are going to make an outdoor data-logging application, you will find that Seeeduino Stalker is the best board.

The main purpose of creating this series is to create an X-bee carrier board so that users can make outdoor application more conveniently. Ever since the first version be released in 2009, Seeeders have been continuously collecting feedback from users and kept upgrading the board. there are 6 versions ever existed during the past 7 years, this summer we are excited to release the most updated member of the Seeeduino stalker family--Seeeduino Stalker V3.1.

Seeeduino Stalker V3.1 is not just a simple update of V3.0. The main surprise you'll find about the board is impressively low power consumption, in sleep mode, the output current of the whole board will be as low as 100uA,the mian reason for this progress is that in V3.1, when MCU is in sleep mode, all other power supplement, including Bee area port, 3.3v port, VCC can be cut off manually, so that power can really be saved.

Changes from the Stalker V3.0

  • There is a toggle switch added to X-bee area, which allows you to select either the hardware serial port or software serial port base on what you want to connect.

  • We also added 2 toggle switch on RTC circuitry corresponding 2 INT pin of MCU, so that users can easily choose which INT pin to be connected with RTC INT port then activate MCU.

  • 1 toggle switch on Bee socket

  • ŸMicro-SD card socket

  • ŸI2C Pin header (operation voltage is selectable: 5.0V or 3.3V)

  • ŸUser defined LED

An Enigma
I became interested in the life of Deng Xiaoping after reading THE TRAGEDY OF LIBERATION by Frank Dikotter and AVOIDING THE FALL by Michael Pettis. Deng is an enigma. He was a key player in the Chinese leadership from the earliest days. He was one of the core revolutionary leaders and one that was heavily involved in directing military campaigns leading to liberation. Afterward, he was the administrator for Sichuan and southwest China and implemented Maoist programs that led to mass starvation and incalculable human suffering. So, how was it possible for Deng Xiaoping to emerge as supreme leader of China, opening up the country to 4 decades of unprecedented growth? Did he learn from the failures of earlier policies? If so, what led to his change in thinking and when did it happen? Or was he always a pragmatist and a loyal follower? And if his thinking did change, how was he not one of the many leaders who were expelled from the Party and sent to prison or executed? It seems highly unlikely that a country that went through the purges, the witch hunts and the upheavals like the Cultural Revolution could have produced a leader of the stature of Deng Xiaoping capable of implementing the policy reforms that have led to China's 4 decades of unprecedented growth. These are the questions that motivated me to tackle this 800-page biography. Ezra Vogel is one of the world's pre-eminent China scholars. His knowledge of the events, people and places as well as the research of other scholars is second to none. He uses this knowledge combined with written accounts and interviews to piece together a comprehensive history of the life of Deng Xiaoping. The account is not strictly chronological. Vogel takes different periods of Deng's life and divides each period into a set of topics covered in separate chapters. This makes the explanation of the events driving each topic easier to follow but it means that the reader may lose track of contemporaneous events discussed in a previous chapter. Unfortunately, Vogel's review of the life of Deng Xiaoping has not fully answered my questions but it is not for lack of trying. Vogel points out early in the book that Deng Xiaoping did not keep a diary or personal writings or confide his inner-most thoughts on government policy with those around him. His speeches were well-organized and thought-out but without written notes. Consequently, we have no window into his thoughts; we have only his actions and events surrounding him to judge his thinking and how it changed over his life. This lack of a personal written record no doubt was a key factor in his survival of the many leadership purges under Mao Tse-tung. Another factor was his complete loyalty to the Party and to Mao. Although Deng was removed from top leadership positions three times in his career, including a 3-year exile during the Cultural Revolution, he was never expelled out of the Party. We also learn that Deng Xiaoping was, above all, a pragmatist and a patriot. His driving motivation was to do whatever necessary to foster China's economic development and re-emergence as a global leader. He was not an ideologue, although he was a skillful politician, sensitive to those who opposed his ideas and careful to find ways to test out policy reforms in isolated cases before moving toward full implementation. Deng Xiaoping is easily one of the most important leaders of the 20th century. We are indeed fortunate to have Ezra Vogel's scholarly and literary talents applied to an English biography of Deng Xiaoping. There is much we can learn from Vogel's account but even more that is left for interpretation reading between the lines.

Not so much
Format: Hardcover
I can't judge the social science merits of this study. But it's treatment of premodern Chinese history is shoddy and ill informed of the existing literature.

The Future is Now
Format: Hardcover
The author makes a compelling argument that the world is fracturing into two principal trade blocs, the U.S.A bloc and the China bloc. Even cursory review of the daily business news confirms the author's argument is taking shape now. This is an important book for those interested in geopolitics, economics, and even those who are trying to determine where to invest their funds based on changing global dynamics.

Cute book and engaging story
Format: Paperback
My grand daughter reads at a 3rd grade reading level, so doesn't want to read the easy readers but loses interest easily with traditional chapter books. This little book was a perfect fit. She's an axolotl fan so the pictures and the story line kept her engaged. There's even a couple of pages of axolotl facts at the end of the book. Well worth adding to her book shelf!
