Hack-a-weekend PM2.5 351-027_giraffe_push_up This weekend Valentin wanted to do a little hack-a-weekend as a surprise, he had ordered parts throughout the week and unveiled the weekend plan on wednesday to a few people, what he wanted to do was represent the PM2.5 data we’ve all heard about in some fun way. His initial idea involved those push button dolls that collapse when you press them from the bottom. So with all the different PM2.5 sensors he could find the challenge began saturday. first was how do these things work! not exactly rocket science but they do mean looking up the datasheets to get the schematics and a little trial and error. then it was deciding what form it should take, perhaps a representation of a tree would be ideal! so with 3d printed parts the tree was assembled with rubber bands, unfortunately both the bands and 3d printed parts just were not working very well. IMG_20130526_180103The 3d printed parts were scrapped in favor of Ping Pong balls just because we had (100’s) left over from a little prank on Lucio’s locker, and string! IMG_20130526_235609Finally the little thing was built, hooked into the pachube/cosm/xively (or what ever you want to call yourself today) and data is starting to flow, we also had built a 2nd one so we can contrast the information and see which one is accurate to whats being captured (outside) just 800m from us at the US embassy in Shanghai. so without further a-du meet the tree! well its version 1 of the tree sitting on top of burty, so we can spend some time understanding it’s readings before making a permanent one with the choosen sensor. if you’re looking for the data, you can find it here, we’re not stating any facts and not guaranteeing the data either as we have nothing to calibrate against: https://xively.com/feeds/135383882 the code can be found on https://github.com/xinchejian/pm2.5-arduino The pm25-tree is the data from the tree using a seeedstudio dust sensor – which doesn’t seem to be there accurate, where as the pm25 is test data from a sharp sensor which so far is accurate but blowing smoke across it did not change it where as the seeedstudio one did change, only time will tell. stay tuned for more from Valentin]]>

Night of IoT with Rob van Kranenburg on June 5

May 13th, 2013 § 4 comments § permalink


There will be Internet of Things China 2013 Conference & Exhibitionin Shanghai from June 4 to 5. More information about the conference here.

Rob van Kranenburg founded Council, a think tank for the Internet of Things, to bring this latter perspective into the heart of the debates. He is Chair of the Working Group Societal of the IOT Forum, member of the Expert Group on IOT for the European Commission, and Stakeholder Coordinator for IoT-A. Mr. van Kranenburg will travel to Shanghai for IOT 2013 China.

Rob is good friends of both XinCheJian and Xindanwei and we are happy to have him coming to XinCheJian for a night of Internet of Things on June 5th. The event will start at 7pm in XinCheJian (1035 Changle Lu, 2F) featuring these speakers:

  • Rob van Kranenburg: Internet of Things
  • Dr. J. (Sjaak) Wolfert: SmartAgriFood
  • David Li: Makers and IoT

The Internet of Things (IoT); imagine a world where everything can be both analogue and digitally approached – reformulates our relationship with objects – things- as well as the objects themselves. Currently we can discern two main blocks of thought on IoT. The first is a reactive framework of ideas and thought that sees IoT as a layer of digital connectivity on top of existing infrastructure and things. This position sees IoT as a manageable set of convergent developments on infrastructure, services, applications and governance tools. It is assumed that, as in the transition from mainframe to Internet some business will fail and new ones will emerge, this will happen within the current governance, currency end business models. The second is a proactive framework of ideas and thought that sees IoT as a severely disruptive convergence that is unmanageable with current tools, as it will change the notion of what data and what noise is from the supply chain on to ‘apps’.
