First -- come comments on the photos on the web site.

Assuming that you have done any processing on the images, I
suspect that your monitor brightness and contrast are not set properly.
The images, as I downloaded them, are too dark by far to make it
possible to interpret what is in them. I downloaded some of them and
processed them locally to get a better view of things. (Below you will
find a description of what I have done to them so you can experiment
with the same things and see what kind of difference it makes.

You want to get a grayscale image and adjust the brightness and
contrast until you can (barely) distinguish the darkest block from the
next darkest, and the lightest from the next lightest.

Then you are in a position to start editing the images --
though if you can control the gamma of your driver to the display, you
may want to tune that too to match your monitor. The gamma which is
correct for a CRT is not correct for a LCD monitor.

Anyway -- once that is done, and assuming that you are using
"The GIMP", when you bring up each image, first click "tools" in the top
of the window, then select "Color Tools" in the sub-menu, and below that
select "curves"

This will bring up a histogram of the intensity of each image.
For your images, what I had to do to make them easier to see is to first
click on the top-right corner end of the diagonal line, and draw it
along the top line until it was over the next vertical line in.

Then I moved the mouse pointer to the middle of the diagonal
line, clicked and drew it up a bit towards the upper-left-hand corner.
(View what is happening to the image as you do this, and release when
you are happy with it.

then, click "Ok" to accept the changes and banish the "Curves"
window.

Then "^S" to save it over the existing image (this assumes that
you have saved original copies else -- otherwise use "^-shift-S" to save
it under another name.

I saved and edited images "28-September-7766.jpg" through
"28-September-7766.jpg" before I got tired of waiting for the downloads.
(You saved the images as 3872x2592 images, which took forever to
download.) And some (especially the screen images) could have
benefited from cropping as well.

It is nice to have the full resolution available to answer
questions, but I would suggest that you make half-sized thumbnails to
view on the web -- and links to allow downloading the full-resolution
image should I (or someone else) want the higher detail.

[ ... ]

Clearly a work in progress, but it is closer to finish now than it is
to start and it works.


Now -- some suggestions for *keeping* it running:

1) Put a hinged clear plastic window in the opening in the pod to keep
conductive chips out of the control switches.

2) *Especially* -- put a door on the electronics enclosure.

Your machine makes nice conductive chips. If these get into the
electronics housing, they can fry things. (This *might* be what happened
to your servo amp (drive).)

Good Luck,
DoN.
