On "coming back" to MRL. . .

I made a couple posts earlier today and managed to get GroG's attention, and a hearty "welcome back."  He also asked if I had a specific goal or reason for my Processing request.  I'm going to try to answer that here.

Question about "Processing"

So uh, about a year ago I took an introductory programming course in the Processing programming language.  I'd experimented a bit with Processing in the past with Simple Open NI, and found it a bit easier to pick up than Python--probably because of how quick and easy it is to get interesting results with just a few lines of code.  One of my class projects was a Ping/Arduino/RasPi radar scanner and display. One of my classmates experimented with face detection in OpenCV.

One of the things I learned about Processing was that its core is Java.

I Can Haz a 3D Printer! (If I can figure out how it workz.)

So, almost two years ago, I put down $400 for an "under development" 3d printer that was supposed to ship in 2 months or so.  Almost two years later I finally have it.  For my money, ultimately I got the printer, and 6kg of 1.75mm ABS plastic.  It seemed like a good idea at the time and I think it still is.

GroG fixes Odroid OCV without even trying

I haven't been very active on the MRL website for a while now, but I haven't really left.  Lately I've been playing around with an Odroid X2 which is a very capable ARM dev board.

Murrman, a user on the Odroid forums has created an Ubuntu based image for the Odroid X2 that includes ROS, OpenCV, and OpenNI including drivers for the Xtion Pro Live sensor.

The battle to retake OpenCV (Or MyRobotLab finds my face)

The thing that I really REALLY like about MyRobotLab, is that GroG has taken really difficult things like speech recognition and vision processing and made it "monkey pushes the button" easy.

Further adventures in Xtion

Pioneers are the guys with the arrows in their backs.  GroG can probably tell you all about that.

Here's a portion of a screencap I made while trying to sort out some driver/hardware issues.

Basically, it's a matrix of versions of the same software arranged by where they were procured from.  But first, a little explanation might be in order.
