Raspberry Pi: camera video stream to host

While playing with the raspberry pi camera I found it hard to know if the camera was working or trying to tweak settings. I was using raspivid -f to preview the video. This was limited with being open for 5 seconds ( can be adjusted using the -t flag and passing it seconds in milliseconds ). The solution was to open a streaming video from the raspberry pi and view it on my host ( mac ).

Davinci XYZ 1.0A 3D printer Repetier Host Firmware and Mac OSX

A while ago I picked up a Davinci XYZ 1.0A 3D printer. I mostly bought this for three reasons:

  1. Ease of use as I was just getting into 3d printing and wanted something that would be a good step to start printing what I wanted. This is done w/ filament cartridges that know what type of material it is and configures the printer accordingly.
  2. 7.8″ cubed print bed, this was the larger printer volume on the market for the price.
  3. Cost

After a few mediocre prints, I found out what some of the complaints were about. First is the EPROM chip in the filament cartridges. This seems like a bonus at first, but after you realize the cost per kg of the filament, you realize the price is obnoxious. You are forced into using their proprietary filament which is limited and expensive. There are ways around this like an EPROM resetter using an arduino.
