Helper Sessions and Assistive Devices group is growing, another new member joined last week and is learning Arduino – from blinking LED to accelerometer! A big feature was added to the air-mouse – a virtual mouse button. The virtual button (gesture) is controlled by horizontal shaking as seen in the video. You can also see the mouse control needs a little fine tuning.
Code is is on github. The Helper sessions are about sharing and learning anything. The Assistive devices are used as one focus for learning.
If you would like to join in and just explore a big range of hardware including the new Xadow, a wearable Arduino, that has eight add on modules and a wearable frame to mount the modules inside, all just shipped directly from the SeeedStudio research lab – hence at least one minor issue to fix. There are also bluetooth devices, 3D printing, eyetracking and heaps of code to write, so come and join in Thursday night from 7:30, no experience required, just Xinchejian membership.
Group members also arrange to meet at other times, so make contact directly or via the mailing list to arrange! Several wiki updates including this new page for heaps more good stuff to work on! More information is here and here.
Make something this summer!
Processing workshop went well on the weekend, for those that missed it, well worth checking out when it comes up again. just a friendly reminder that if you havn’t paid your membership dues, please do so at the space. in August paul will be running a free Arduino workshop for members only make sure you have your own Arduino kit, buy through the space to support XinCheJian. also let us know what you think about the new design on the xinchejian website. A friendly reminder that XinCheJian is a hackerspace and not a co-working space/cheap office space, its fine to work on your projects but not cool to run your business out of the space, people involved in this are kindly being asked to move to a co-working facility, we can make introductions if you need them.
Just a reminder, if you would like to socialize or network please wait until after the presentations or go outside to give the presenters a chance to.. present.

Ladies and gentleman! start your engines, we’re hosting the XinCheJian Autonomous robo-racing at the Shanghai Library on the 3rd floor THIS Sunday
XinCheJian’s Toughest robot challenge is about to begin, Autonomous Robo racing, all based on sensors and time on the race track, from 1pm – 3pm we’ll be racing at shanghai library and competing for the fastest time on the track!
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
There’s a group buy happening right now! and a competition going on!
Dagu electronics has announced a competition: use a doodlebot to make the most awesome drawing to compete for prizes, plenty of prizes to be won! read about it here: http://letsmakerobots.com/node/37126
Lutz a long time member of XinCheJian has contacted them since we’re in china and negotiated a great deal if we do a group buy, our target.. at least 20 pieces and our price.. 198rmb/each
if you want to get a doodle bot and not participate in the competition instead that’s fine! but if you want to get in on the competition, then it’s even more awesome!
here is more information about the competition: http://letsmakerobots.com/node/37175
Sign up to the XinCheJian google group (email firstname.lastname@example.org), Send an email to email@example.com titled “programming competition” with the words “i Pledge to buy X amount of Doodlebots if we succeed in our group buy” then get ready to send 198rmb to a group buy alipay account or drop into XinCheJian and hand over the cash to a staff member! Lets put a deadline of May 22nd on this so we can hack the doodlebot sooner than later. Do not transfer or pay until Lutz gives us the word via email and verify it by checking http://xinchejian.com website.
Once the pledge is made, you’re on the hook for the cash!

Happy new year. Right to the beginning of the new year of the snake here the new video of our city project. This shows the first test with the 3D mapping and projection. The robots are not moving yet since the roads are not completely done.
We’ve started a new project in Xinchejian, the Project City, code name “Metropolis“.
More about the project will be in the wiki soon as we just begun. Today we built the table where the city will be installed.
The project will be a fusion of 3D projection and robot hardware combined with mechanics and interactive components.
This project is open for all members with interest. There will be a huge part in 3D mapping/projection and this content has to be created too. The robotics and mechanical part will include Arduino based hardware for the movements, communication between the central computer and the city and interface for interactive components.
If you think you could help with something then just let us know.
X-Bot is evolving and now already smart enough to follow another X-Bot. What is so special about that you may ask. Well, there is this small quite technical looking robot and there is a program running in X-Bot’s brain (also called Microcontroller or MCU). To follow another robot means that they need to communicate and this works with infrared signals going from the leader to the follower and back. Leo did the programming and the hardware and is willing to share that with you. Just check this website regulary and see when the next workshop is scheduled. Build your own X-Bot in Xinchejian
If you want to support the X-Bot, buy a couple of them or just help to develop it further then please go to http://dreamore.cn/Project/Show/512 and see more details there.
