Hey guys,

Sorry for the lack of new on the NIR probe, have spent two nights in a row
on the phone to Denmark getting all my paperwork in order to file my
immigration case on time (Monday), so I haven't gotten anything done yet
except draw a sketch of my idea (added it to the last  blog post, too) and
buy ~$2.00 worth of acrylic to play with. Hope you'll bear with me for
another day, am out to buy fish-friendly silicone first thing tomorrow =)

Conc. the scale, Mike, I'd love to have it for Biobridge in general, as it's
got way better resolution than the ones we have already, but I don't think
we need the temp. probe - believe we've got enough thermometers as it is.

Do you want to add the links, Rolf, or should I? Am planning to rework the
project wiki pretty heavily tomorrow anyway (it's not quite as "clean" as
I'd like, and certainly not up-to-date), so I could do that at the same

Anyhow - more tomorrow - pleasant weekend, all =)
