Push on back end of webcam and the inside part will slide completely
out of the metal tube:
Remove four screws as shown:
Remove top piece from lower piece and lift circuit board/lens
assembly from lower piece:
Desolder these two leads and remove assembly from circuit board:
NOTE: The photo below is the back
side of the lens assembly. If you want to reuse the webcam lens
but convert it for daytime infrared imaging, this is the original
infrared cut filter that you would need to remove. Then follow
the above steps in reverse as a guide to reassembly.
Place circuit board/imaging chip inside lower half of black plastic
piece. Insert microphone ribbon cable into its connector and push
rubber microphone into body above the circuit board:
Screw two 1.25" eyepiece barrel extenders together and slide
onto the USB cable:
Step 23. Place
USB cable strain relief plug into position and install split ring
clip to hold it in place:
Step 24. Place
upper black plastic piece onto lower piece and install four screws.
Reinstall the small metal grounding clip as shown on left edge
of photo below. Note how ribbon cable is bent and pushed fully
inside the housing:
Step 24. Slide
webcam into the eyepiece barrel extenders. In this photo it is
shown half way in; be sure to push it in all the way. The webcam
is a perfect fit for the eyepiece extenders I used and fits inside
them very snuggly.
Step 24. Glue
grey plastic ring onto the end of the webcam with hot glue. I
used a small piece of air-conditioner filter material (foam) to
seal the hole around the cable:
Step 25. Screw
1.25" nosepiece/T ring adapter onto the eyepiece extender:
Step 26. I
used a 1.25" eyepiece barrel locking ring to secure:
Step 27. Connect
the webcam to computer and test. There will be a bright blue light
from an LED near the imaging chip that needs to be disabled. I
used ultra flat black paint and a toothpick to put small droplets
of paint on the LED while it was on, until there was no light
being emitted from it. Because we kept the webcam's microphone
connected, it continues to operate after the modification.
