- During the workshop you will be provided will all the necessary materials.
- A guide will be presented showing the major steps of how to complete your SUMO robot.
- And hands-on help during the day
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.

- DFRobot is going to introduce sumobot challenge this evening!
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.
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!
