setting up Raspberry PI

[Roni Segoly]

I have worked on RPI setup on recent days

I have two setups now both work automatically and autonomically (cellular modem)

1. RPI with Webcam

• It takes a picture of light source (sky?) every X minutes
  
• The file is parsed as JPEG on local memory. 
  
• Levels of RGB of all pixels are read 
  
• The final output is average of RGB
  
• Data is stored at data.sparkfun, and can be exported, later I will add data from sensors( https://data.sparkfun.com/yozmargb)
• Data is plotted automatically at plot.ly (currently plotting last 24h https://plot.ly/~rsegoly/712/rgb-colors-201507021600/)

2. RPI with spectral workbench spectrometer (almost done)

• It takes picture of light source every X minutes
• The file is saved as JPEG and parsed
• I have the values of the actual spectrum portion in the file, as it does not change, and it is being cropped accordingly.
• The cropped image is parsed, all RGB values are summed in columns, so I have one line with sum of RGB values for each entry
• The image is plotted automatically at plot.ly, after being calibatred with values I set before, as it does not change (https://plot.ly/~rsegoly/752/rgb-colors-fro-cropped201507021342/)
• If there will be a way, I will upload the cropped images to spectral as well.

In both cases I used JPEG, I know it has disadvantages as data is compressed 

What was important cor me is the process to be easy (for children) and automatically

Wow, that's very cool!

IT's great seeing the progress you've done!
