1. All questions welcome
2. We all share and help each other
3. Make & hack stuff – anything!

      …. one theme will be assistive devices as this covers a huge range of technology!

Anyone is free to suggest other themes! All languages are welcome. Proposed guidelines

• Display “Helper sessions” welcome sign – so people know were to come (don’t be shy !)
• Setup at one table/area – with chairs and clean workspace.
• Noisy discussions should move to another area, so main group can continue.
• Share and document – let other people know if you had a good time, or learnt something (or not)
  • Ask for wiki account and how to use the wiki!
• You need to be a member

These sessions are intended to extend the always great help available at anytime at Xinchejian 🙂

Aim is to fit in between formal workshop Xinchejian learning and to give some relief to Xinchejian regular members as they often spend most of their time helping others. THANKS for all the interest and support after Wednesday nights talk! When:- Trial Thursday from 7:30 starting from 11th July. If any interest we can try other times, including weekends. Where:- At Xinchejian Cost:- Free, but members only (100RMB per month, cheaper for longer periods) Links – Early draft pages have been started on the wiki:- Helper Sessions    Assistive Devices These will be added to in coming days and weeks. Note “Helper sessions” is a draft name – fits in with Maker, hacker, and also fits in with assistive technology. Any better suggestions?]]>

Hack-a-weekend PM2.5 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. The 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! Finally 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]]>
