Good time isn't quite a done deal yet. =A0
There are some relatively minor
changes to gpsd and a bit more hardware testing between here and there.
I'd say two weeks, assuming we don't run into any boojums. =A0And I= won't
sign off that the job is *really* finished until we can document hard bound= s
on the jitter using something like the test rig Patrick Maupin is trying to build.

Tell me when a good time to pull is. I w= ould certainly like to try current against
the wndr, as what andrew had = tested was gpsd 2.X.
=A0

By the way, I've had a third GPS vendor - a U.S. outfit called Parallax=
Systems - get back to me with interest in the Plain Jane timing-GPS mod
(connect 1PPS to DCD in a stock design using SiRF+PL2303 or functional
equivalents). Had a long, friendly phone conversation with one of
their design guys.


Did ublox ever get back to you? Sexy sadie is cal= ling...



Actually, it still kind of blows my mind that I've been able to
social-engineer all this with a handful of emails.

an= d a couple blog posts!
=A0
=A0Woulda been the
stuff of cyberpunk novels before the century turned...

The whole maker movement is a barrel of fun! While I didn't
car= e for much of Stevenson's "Diamond age", the core concept
of a reprap and related is becoming more real by the day.

Hmm... self replicating gps and networking gear... hmmm...
