The tolerance issue in 3D printing

These broken parts are gonna delay my work ...

 Totally new printed encoder parts were received on 9th of May 2011, and one of them(picture below) was broken into two pieces while being mounted on the same day

Supervisor Meeting

Today I had a very quick supervisor meeting with my supervisor. Results :

• I got the spare part for encoders, so now I can start to test my positioning code
• I got some tips about I2C technology(Several cards connected together with the same wire)
• I will have wired(RxTx, I2C, Dig2Dig, etc) & wireless(Xbee, ...) networking of Arduino cards discussed in my thesis
• I got tips that there are more products/technologies than Xbee 
• I get to write more about "Van der Waals" technology & discuss related to the conditions in offshore.

Finally OpenCV 2.1 & MS VC++ 2008 worked together ...

This is OpenCV helloWord program which is an easy code that just opens one picture. Too sleepy to continue today ... OpenCV 2.2 is too much unstable and I couldn't get to make it work with MS VC++ 2010. Downgrade worked :-)

Good night
