The saying is that bad things happen in threes. I certainly hope so,
because I've had three to last a while. Maybe they'll make you feel
better about whatever's bugging you.

In mid-March we had a strong local windstorm that actually snapped off
the piling that secures my boathouse and my neighour's on one side. As a
result, his house crushed mine against the one on the other side to the
extent of $7 BU's of damage. The three pieces of good news were that the
boat was completely unscathed, the damage was so well repaired that the
house is truly better than it was, and I had insurance that covered the
costs. Not too bad in the end.

Last week-end, while driving home from a pleasant few hours on the boat,
the head on my sports car cracked, oil and coolant mixed, and a lot of
damage was done to bearings. The replacement engine arrived today and
will be installed early next week. Cost will be 4-5 BU's. The power
train warranty ran out a few months ago. Darn. Or something like that.

The third bad thing is just continuing aggravation but with a promising
outcome. You might recall that I've been experimenting with an
iPAQ-based navigation system. Next time I'll buy a package rather than
components.

The first GPS I bought for it was the Navman. Designed specifically for
the iPAQ, it's very elegant, but performance wasn't nearly what I
expected so I returned it. (Arild has a similar setup on test, and is
much happier with his, so it might be that I just got a marginal unit.)

Since all I need is basic position data, I then bought en eTREX which
performs very well using my laptop, but doesn't have a connection to the
iPAQ. No problem. (Ha ha!) Found a company in Massachusetts that sells
the 22 pin iPAQ connectors and bought some. Also bought a bare-end cable
for the Garmin from another supplier. The connectors arrived within a
few days, and it was immediately obvious that the pins are so tightly
packed I wouldn't even attempt the soldering job - heck, I could hardly
differentiate them. I decided to take everything into the electronics
shop and have them do it

Meantime, I asked Compaq for the pinout info, and that proved to be a
real trial involving phone calls and e-mails. A good guy in Support
finally pointed me to the Compaq Developers website where I eventually
located and downloaded several data sheets showing the construction of
the connector and the necessary pinout info.

But not quite.

Arrived at the electronics shop to realize I'd left the data sheets at
home. Went home to get them and returned to the shop. The tech noted
that none of the info indicates which pin is number one. Went home, and
got that from the connector supplier. Also got the Garmin wiring from
the Garmin website. Back to the shop, but they were too busy to do it
while I waited. Went back this morning, and they did the job, but it
didn't work. The tech thinks that a couple of cross-over connections are
also required, but he didn't want to risk damaging the iPAQ without more
info.

Returned home and on the web, found a DB9 serial cable specifically
stated to be used to connect a GPS or other serial devices to the iPAQ
3800. Compaq doesn't offer one yet. When it arrives next week, I'll
solder a mating connector to the Garmin cable and see if that works.
Will let you know.

Have a great week-end. I intend to.

Cheers, Garrett
