PythonCv in "pi"

running "wheezy" on pi - tightvncserver runs on pi - vncviewer on fedora (f17)

running a sample py script contours.py for opencv samples

someone posted a question in Raspberry pi fb group - about installing and usin the python interface of opencv in pi - i have installed and tested opencv in pi from both pre-built package and compiled from src c0de - never tried python interface of cv - now managed to install pythoncv on pi and tested a sample code - these are the steps 



1. Install opencv 
$ sudo apt-get install dev-opencv

2. Install python dependencies
$ sudo apt-get install python-numpy 
$ sudo apt-get install libpython2.6 python-dev python2.6-dev 

3. Install python-opencv
$ sudo apt-get install python-opencv

4. Go to samples/python/ folder of Opencv src code 
(and run a python script)
$ python contours.py

Some "wget" magic

files mirrored from aishack.in

wget running in shell

watched the movie "The Social Network" a few days ago - noticed the phrase "wget magic" - wanted to try it - it sure is useful - i have been following the site [aishack.in] for Vision part of my project - now i can mirror the site (i am doing it) - (ie) take a copy of the entire site data - so i dont have to go online to view the post every time - reading the man page of wget - planning 2 use it along with htmldoc or something like dat - EOF

The Mess i make

arduino - motor-driver shield - dc motors - multimeter - usb cable - batteries - chasis - breadboard - wheels

currently workin on a project - adding vision to a stupid bot - experimenting with OpenCv libraries - the bot is supposed to pickup some dummy objects - so it needs a grabber (duh) - the servos i have are useless - planning to implement it with dc motors (and some smart programming) - arduino - need a motor driver shield for running the motors - planning on buyin a shield with a feature to directly plugin bluetooth module - need a dc motor with higher torque than others for lifting the grabbing up and down - EOF
