Anyone know of a driver for vista 64?

Thanks

Last week I bought a Holux M-241 and a little confuse to operate it, especially how to tagging GPS Log to the pictures.
Lucky me…to find your blog… now I can operate my Holux M-241 well… Thank you

“my small 13″ notebook with me, just in case the GPS logging device runs out of storage”
-> Now your Java Phone will do ! (BETA J2ME Version of BT747 is now available).

That’s true Jan, I don’t see the need for using waypoints in geotagging photos either when it works so well automatically. However, if you want to geotag and record track logs with points-of-interest simultaneously it makes the world of difference. For example, I will use the same logs to show our itinerary with precisely-located POIs that can be downloaded and exported for use with a TomTom/ Garmin PND.

The deer was near Bridge of Orchy, semi-tame I think because of its proximity to the rest area, but not tied up nor fenced in so not entirely safe ;-)

Do you really think going from a 5 to 10sec interval would have a significant impact on battery life Jan? I’d assumed, perhaps incorrectly, that signal reception was a passive affair. It would be an interesting test to carry out if we could somehow account for variation between batteries…

Bruce, you really got some awesome photos in your gallery. I’m amazed how close you got to that deer AND managed to get a good shot at it. By the time I fumbled my heavy tele lens and converter out of my backpack they were always at least a mile away. You also managed to find a perfect “phone booth in the wilderness” motive :-)

I didn’t use the M-241 to mark waypoints. I just left it running the whole day. Chances for an exact match between a log record and a photo are very high so I didn’t even think about pressing buttons on the logger.

I’m thinking about going to a 10 second interval instead of 5 too if this further extends battery life on the M-241 but I guess it will be about the same because writing to memory doesn’t use a lot of power. But tracking the GPS signal does.

LOL; we just returned from a two week holiday geotagging in the Highlands too :-) I was planning to take the M-241 but was concerned about battery life, since I wanted it to log from the time we went out the door until we got in for the evening i.e. from breakfast until after dinner, covering some 1768 miles. So I took the Mac-friendly BT-335 which logged at 10 sec intervals for two such days, before I recharged it "just in case". We did have a laptop, so I did do daily log downloads. Amazed at how many places (all but one) we stayed in offered WiFi, so GPSPhotoLinker could perform reverse geocoding via a server (Geophoto can do that offline, to its credit). Did you use the M-241 to mark waypoints? Until I read your update and checked out the new version of BT747 I didn't realize it could now distinguish waypoints from track points (see here), a feature sadly lacking with the BT-335/ DG-100 units I've tested. You got some really super photos there; I use Gallery 2 with the Google Maps module to display geodata (see here for my Scotland pics).
