How To Modify A QuickCam
The black and white Quickcam digital camera uses
the Texas Instruments TC-255 CCD chip. This is the same imaging chip found
in several cameras designed specifically for astrophotography. To use
it, I opened the Quickcam shell and removed the circuit board. **WARNING: opening
the camera shell will void your warranty!

First, the ball housing must be pried open. | |
Once opened, the metal weight/mounting nut can
be discarded and the circuit board removed. |
|
This photo shows the various parts that must be
removed to expose the chip. |

The CCD after the filter and lens assembly have
been removed . The telescope will become the new lens. |

Here's the CCD on the board ready for a new
housing. |
I have found that the plastic lids of 18 oz. peanut
butter jars (shown in blue) are the ideal shape and size for the new housing. For the back of the housing I used the clear top from a can of potato chips. |

The CCD is seen here through a hole that I drilled
in the center of the lid (this one happened to be red). The two screws that held the lens assembly now hold the circuit board to the inside of the lid. The black circle is the inner thread ring removed
|
The painted, finished camera is shown here
with a 1.25" barrel screwed into the T-ring. This allows the camera to slide into the telescope in place of an eyepiece for prime focus work. Other collars can be attached for eyepiece
