A friend in XinCheJian hackerspace Shanghai asked me today what I have been up to. I was thinking not too much, as I have watched quite a few movies (Sleep Dealer is pretty good, Avatar was way better than I expected) and re/read several books & magazines, but then I started to list some of the things I have been doing…….

  • PartTester – built 2nd board with 1% R – did not work, and now 1st one not working – same issue, eventually worked out LCD had partially died on trip home from China.
    • Looking into ways to do improved or auto-calibration
    • As part of above, part of X-bot work discovered that Gerbers used for PCB production have an electrical issue where 328 processor digital ground is not connected. This is only in the Gerbers – the schematic is correct!
    • Red circle in photo highlights difference between “good” gerber (blue) and my gerber with missing ground connection.
    Gerber issue ground not connected to Atmega328 ground!

    • X-Bot – learning SMD soldering (old, unrefrigerated solder paste = :( , new = :) )
      • Made a pogo pin ISP connector to easily test if processor was working
    • Playing with el-cheapo Taobao STK500 programmer (good in HV mode, but can’t get it working in ISP mode)
    • Fighting several nasty computer issues
      • XP system freezes for 1/2 to 3-5 minutes yet CPU is at 1% and no other symptoms or errors!
      • XP ongoing anti-virus software instability issues
      • battling security update issues on XP and Lububtu
      • Lubuntu intermittent keyboard & mouse issues – only some keys/buttons work!
      • Lubuntu SMB file copy issues
      • Lubuntu “system problems”
      • Lubuntu restoring backups – path too long
      • Unsuccessfully trying to install Windows 7 to SSD and user directories to different disk
      • Unsuccessfully trying fix injet printer ($$ cartridges, cleaned, factory resets, extra cleaning…..)
      • …..
    • Replacing swimming pool pump (now pool is leaking – think it is drain system)
    • Car window electric winder replacement
    • Fixed front door lock
    • Home Theatre – fixed bad solder joint that stopped right channel working
    • Toshiba SD-K310P DVD player won’t play disks – seems like region free hack has stopped working
    • Dish washer – bottom arm won’t spin .. ongoing effort to fix
    • Backyard jungle:-
      • Getting rid of dangerous European wasp nest
      • Digging ditch for irrigation system repair
      • Hacking away at six months growth (two trailer loads so far), have not even started on the 80+ meters of hedges yet!
      • Watching Cockatoos, King Parrots and Roselas
      • Saw a falling star
      • Cleaning up flood in garage last night due to major storm – we were lucky – could hear clean up with chainsaws nearby.

Xinchejian SwarmRobotsThe fantastic capability of the XinCheJian SwarmRobots has been recognised with 2nd placing in the AFRON $10 robot competition Traditional (Roaming) category. The announcement made at World Maker Faire today (via Wired) awarded first place to Harvard’s research group and third place by to MIT University. XinCheJian’s high placing against such prestigious competition highlights just how good XinCheJian’s SwarmRobots are!

The SwarmRobots are still under rapid development with work progressing on coding object detection and inter-robot communications using the already developed InfraRed shield. Work is also underway on wireless charging and a Atmel 32u4 version. It has been a lot of fun to be part of this team as can be seen in these videos!

Three Xinchejian SwarmRobots

Had fun at Shanghai Barcamp Fall helping to show off Xinchejian’s SwarmRobots. It was great seeing how all the children (young and old) explored the robots ability and asked heaps of questions!

Also helped with a presentation about Xinchejian’s SwarmRobots and the AFRON $10 robot competition and I gave one presentation on one of my favourite topics “Instantly turn your project into a kit” available in Libre Office odt and as a power point. It has a LOT of pictures and includes three video picture shows, so it is around 10MB!

Xinchejian Swarm Robots and the new motor driver PCB, IR shield and the Afron competition entry.

Helped run the Xinchejian Advanced Arduino course and getting PartKeepr  setup for Xinchejian.

Plus of course Lophilo- see post before this one!

Enjoying lots of extremely good presentations at Xinchejian – here is a link to this weeks sound and video processing, Nixies and LED cube and Haxl8r!

And there are several other major projects actively being worked on, but none are yet into any state to talk about!
