Lights, Camera…

You know what comes next…

I’ve got lots of cameras from a prior lifetime when I wrote a webcam application. I’d like to be able to snap pix of the Makerbot doing it’s job, so I don’t have to babysit it.

The camera is a 3Com Home Connect USB camera. Pretty generic. I’m using the app “motion” on my Ubuntu 10.10 machine (which is the machine which is running the Makerbot, Freecad, ReplicatorG, etc.) Use “sudo gstreamer-properties” to find out about your video device.
