Fear of Repression Spurs Scholars and Activists to Build Alternate Internets - Technology By Jeffrey R. Young Washington The Most Common XBee Mistakes When it’s late at night and you just can’t get your ZigBee network working, more than likely a simple solution is waiting in the wings. Here are some tips for resolving issues typically encountered when working with XBee ZB (Series 2) radios and Arduino systems. Common XBee Mistakes
IOIO for Android Replacement: DEV-11343. IOIO-OTG is here! Now you can use the IOIO with your Android device or PC! This page is for reference only. Description: The IOIO (pronounced "yo-yo") is a board specially designed to work with your Android 1.5 and later device. The board provides robust connectivity to an Android device via a USB or Bluetooth connection and is fully controllable from within an Android application using a simple and intuitive Java API - no embedded programming or external programmer will ever be needed!
emonTx A low power wireless energy monitoring node. It's designed to sense data from multiple CT current sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. It can be powered by 2 x AA batteries or 5V USB. Parallella: A Supercomputer For Everyone by Adapteva Kickstarter Collections Projects We Love Columbia Law School Magazine Professor Eben Moglen makes speeches. He gives talks every few weeks, across the globe, to critics and the like-minded, in large groups and small. Moglen, who serves as director of the Software Freedom Law Center, does many other things, too—he organizes legal and financial support for programmers; he creates community groups to advance the rights of free software projects—but if you ask people in tech-legal circles what stands out most about Moglen, it is the speeches everyone cites. And if you ask them to name one speech in particular, they will point to the talk he gave to the Internet Society in February of 2010. There, Moglen introduced the world to an idea he had been mulling over for some time. He calls it the Freedom Box.
Dissolved Oxygen Sensor Looking for a way to detect dissolved oxygen levels? If you raise fish, this and a ph sensor are two important things to monitor (and of course, temperature), and an Arduino is the ideal platform to build upon. The Sensorex DO1200 ($139) outputs a <1mv - 54 mv signal indicating DO levels. Use Guilherme Martins : PAPERduino’s design This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D This is the the first version of the layout design, next we will try more designs, and another materials. You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards.
Twine : Listen to your world, talk to the Internet by Supermechanical The Kickstarter is over, but if you missed out on backing us, not to worry. You can still join the thousands of other awesome Twine owners by pre-ordering on Supermechanical. It's the next best thing to being an original backer! Follow us on Facebook or Twitter. Mesh networks and the beginning of borg Last night I got to attend a talk given by Robin Chase, Founder and Former CEO of Zipcar. Her talk was titled “Sustainable Transportation and Accessibility Research & Transformation”, where she discussed how to decrease the impact of transportation on the environment and also using new transportation paradigms (such as shared car ownership) as a vehicle for bringing out mesh networks. Mesh networks are simple: everything is a sensor and can connect to other sensors. She referred to it as “Ad Hoc Wireless networking”, but I think that confuses the issue, because then people start thinking it just means WiFi everywhere. What it really means is that all of these sensors and network devices can talk to one another, gather, share, and use information.
OpenMicros - List of cloud providers Having 'things' on the Internet Of Things isn't much use if there's nowhere on the internet for the things to talk. Luckily, there are several providers that cater for this need. They all have their own way of doing things, and the range from free 'upload your readings here' for they hobbyist, up to fully managed machine to machine (M2M) solutions for even the largest of businesses. What provider is right for you depends on your needs, expectations and wallet.
