7. POTENTIAL IMPROVEMENTS


MICROCONTROLLER

  • The –52i has an onboard rs-422 port, and most importantly has onboard normally-open relays.
    This would do away with the circuit board containing MOSFETs and relays. The onboard –422 port means time saved in soldering your own with a –52 (or not using the st-25 I/O board)



    • CAMERA ENCLOSURE

  • In 2002 I used a RadioShack project enclosure to shield the camera from rain. It wasn’t ideal because:
  • It was black (strong greenhouse effect heated the camera)

  • The front piece was sealed to the body with four screws. These had to be removed each time the camera was downloaded.

  • No gasket. Silicone sealant was used after each download to waterproof the enclosure.

  • Next year I will use this gasketed lexan enclosure.

    • I’ll paint the entire enclosure silver except for small openings for the viewfinder and lens.


    ENCLOSURE FOR THE MICROCONTROLLER AND BATTERY

  • In 2002 I used a small Coleman-type cooler. Unfortunately it leaked even when the lid was thoroughly duct taped.



    • Suggestions for additional improvements are appreciated!


    PROCEDURE OUTLINE
    1. Overview
    2. Solder four wires onto the JamCam circuit board and disable the flash
