I have included file sizes in the image links.  Please take a moment to check these sizes before you begin downloading images for viewing.  Several of the JPS files are very large and will be painful to download over a modem link.

The images are presented in cross-eye and anaglyph format.  If you prefer a different format or size, please give the Stereoscope applet a try.


Viewable with any browser
I strive for browser independence.  Please let me know if you experience problems with these pages.  

 


Java Stereo Viewer
Many of these pages use a Java Stereoscope applet by
Andreas Petersik. It made a Java convert out of me and I highly recommend it.

Examination

Once we have the core free, it is easy to see that this is going to be quite a bit easier than working on the A5.  Everything comes completely free of the cases.  There are fewer components and even air visible between them!

The A100 camera core

LookingConnecting wires to discharge the flash capacitor straight down on the face, we can see all sorts of interesting things.  First that black 55 gallon drum in between the battery slots.  It is a capacitor stores energy for the flash.  First order of business is to discharge that puppy.  Carefully connect a couple of alligator or micro clips to its leads and connect their other ends to a couple of cheap screwdrivers.  Then, touch the two screw drivers together.  The resulting flash and arc will convince you why this was a good thing to do and why you should have used cheap screwdrivers rather than your $20 Snap-On.  In the photo to the left, you can see that I have moved the negative battery cable to allow easier access to the capacitor leads.  

With that out of the way, you can start looking around and you'll notice great big solder pads and wires connecting the batteries to the power supply board in the lower right corner.  Those solder pads will be important later, but consider the size of those power leads.  Those leads have to be large enough to carry the1.4 amps  used  during the auto focus and sensor preparation cycle.  Yes, folks, 1.4 amps.  No wonder the batteries don't last long.

A100 Core from the bottom (47398 bytes)

On the bottom, you can see 

  • the ZIF socket from which you extracted the power switch ribbon cable
  • the tripod mount
  • (most importantly) three good sized air gaps

The two gaps near the CF socket are significant in that they traverse the entire height of the case.  The gap to the right of the battery compartment is significant in that it is a large hole near the power supply cables.

 

A100 core from the top (46820 bytes)

On the top you can see

  •  the shutter button
  • the ZIF socket and screw that will allow you t remove the entire shutter button sub-board for ease of soldering
  • the other end of the CF socket gap
