TomTom One GPS is running Linux

While doing some research on my TomTom One 3rd Edition and GeoCaching I discovered
the my little device is running Linux and appears to be very hackable. (Not that I
have anything that I really need to change on it)

Geocaching with multiple GPS

When we go geocaching we have a couple of different GPS options depending upon which
vehicle we take.

TomTom One 3rd Edition

Mio Moov 200

Garmin 12 (no mapping)

Once we are out of the car we use an old Garmin 12. It is probably 10+ years old.
It is as basic a GPS as you can get with no mapping and no USB interface.

I am working on getting geocache locations loaded into all of the platforms so that
when we are out and about running around we can see all of the local caches and then
stop for a quick hunt if we have a little bit of time.



Here is an interesting solution for getting the locations imported as POI (Points
of Interest) into the TomTom. This will be a hack that I going to try as it looks
pretty simple.

Another option is using http://www.gpsvisualizer.com/gpsbabel/ to
import and export the files over the web. It looks like it supports all of the formats
that I will need.

A couple of the better software packages:

GPS Babek http://www.gpsbabel.org/

Nice Geo calculator:

Geocaching 2009-01-11

Ben has been talking about wanting to go out hunting for a Geocache. I finally got
around to doing a bit of research to figure out the details of the sport. I was familiar
with the overview but needed some details to get us going.

Today we decided to go out and hunt for two local caches in the middle of the deep
freeze that we like to call winter.

The first was for: Kings
Town on the Crow by yoteman (GCZJ19)

After trying to find a place to park the car (LOTS of snow) and then hiking over to
the coordinates we fumbled around in the snow for about 10 minutes looking for the
cache. Ben found it on his own even though it was completely covered with snow.

The second hunt of the afternoon was for:

Sir
Francis by Lloyd family (GC130VD)

After about 10 minutes of walking around and looking right at the spot we figured
it out. It was covered by enough snow that we used a small emergency shovel to dig
it out.

Nice link in the in lid!






I think that we swim here in the summer... hmm.

Here are a list of some of the Geocaches near our home:

Overall a pretty fun afternoon hiking around in the 10 degree weather. Ben was pretty
excited about this hobby after todays adventure. I have to think that is is more fun
in the other thee seasons.



We plan to try to look for some more caches next weekend.
