MANIPULATION 6. Download and manipulate photos


  • Download the photos using the JamCam software.
    Unfortunately JamCam doesn’t timestamp the photos. You also have to use a JamCam to download the flash card (ie. you can’t use a flash card reader).


  • To do the time stamping in the sample movie, I did the following…
  • In my fieldbook I recorded the day & time of the first photo.
  • In Excel I made entries for each photo by filling the cells down by the time increment between photos.
    • Next, I made the excel sheet into a DOS batch file to rename the files sequentially. Ex::
    ren jam001.jpg 06_11_02_1230.jpg
    ren jam002.jpg 06_11_02_1430.jpg...
  • Finally, I made the .jpg images into a .avi movie file using the freeware program Slide Show Movie Maker . File names are printed in the lower left corner. SEE THE SAMPLES SECTION



    • PROCEDURE OUTLINE
    1. Overview
    2. Solder four wires onto the JamCam circuit board and disable the flash
    3. Make a circuit board for relays and MOSFETs
    4. Upload a BASIC program to the microcontroller
    5. Set up the batteries and weatherproof enclosures
    6. Download and manipulate your photos
