Camera Day

[Tom Droege <tdroege@veriomail.com>]

The modification suggested by Graham Davies looks promising though I am yet 
to see stars with it.  So I am inventorying all the cameras and trying to 
get them all up to data.  I have 24 printed circuit boards assembled and 
wired.  There are 8 working cameras including 2 at NOFS.  I think I have 20 
Class 3 and one engineering grade chip, and 10 more class 3 chips on order.

Serial #1 sprung a leak when we put it on TOM Thursday.  It used epoxy for 
the water channel seal.  I now have some Blue gunk that seems to work every 
time.  I am getting to the point where I can recognize problems 
quickly.  These days all cameras look pretty much alike.  A good sign.

A week of work should get 20 or so working cameras.  I am just waiting to 
see stars to make a decision to go ahead with the Graham Davies 
change.  This just involves adding 470 ohms in series with the vertical 
clock lines.  An easy change, but it requires taking the camera apart and 
removing the CCD.  I no longer try to solder on the camera board with the 
CCD in place.  ;^(

I looks like there is a good chance that I will be able to get a couple of 
chips Lumogen coated.  Thus the blue lenses will not go to waste.
