Bad news, good news, good news, bad news....
Played with the logger a bit on the way to work this morning. Battery
terminal popped loose again. I fixed it good this time...Took a piece
of solid 24(ish) gauge wire, bent a loop around the terminal and
created an "extension" lead so I could get through the via and get a
good solder joint. This worked great.
Found an awesome enclosure for it in our parts room:
http://www.pactecenclosures.com/product-detail.php?productid=103&seriesid=57&classid=27
Printed the PCB picture and used it as a template to mark and cut the
display opening and drill for the buttons. Because of the thickness
of the plastic, I had to cut the opening for the whole display not
just the visible area (got a bit carried away with the Exacto). Even
then the buttons are just below the surface and tough to press so I
hit the button openings with a very large drill bit to create a bit of
counter-sink. Finally, I put a small notch in one corner to allow a
lanyard string to pass in and wrap around the screw post. Works
great!
The packing peanut holds the board up against the back of the
enclosure snug. Not exactly production-quality but it is what I had
around.

The second "bad news"...I hit the button to take a snapshot then to
view the snapshot. The logger showed "EEPROM sig OK" and hung there.
It would auto power down, and would power back up but still show the
message. It recovered operation when I pulled the battery but got into
the same state when I tried again. I did a System Menu | Erase All
Data and now everything seems to be working. Maybe something got
corrupted because a write was interrupted when the battery was making
intermittent contact.

Personally I love it, but I can see how someone else might find it hard on the eyes. Maybe you could work on a software mod to use a larger font as an option? You'd have to abbreviate some text, and reduce the number of lines per screen, but it should be doable.
