Long ride

Welshie님이 English로 2008년 5월 6일에 게시함.

After a 64km bike ride at the weekend, trying to find somewhere new near my home to map, the sum total of my efforts is about 2km of fresh tracks, and a few new points of interest. I think that next time, I shall have to plan my route to try to take in some more white space on the openstreetmap maps, and try to aim for streets that are mapped (due to the aerial imagery), but not named yet.

It was also the first long ride out with a Nokia N95 doing the logging. The phone is good enough, but the battery life isn't enough for a 3.5 hour session of tracklogs, continuous music playing, and lots of geotagged photos. I have got a Freeloader solar charger, which managed to keep enough juice flowing when the phone battery was running low. It would be interesting to note how much longer the Nokia battery lasts when not playing MP3s. I'll have a few more long runs before the London to Brighton ride.

Looking at the tracklogs from the Nokia (the phone was just in my pocket), I can easily see when I reached to get it out of my pocket, because the fix wobbles around lots. According to the documentation with the phone, it gets it's best fix with the phone slider open; so maybe I need to work out some sort of handlebar mount. Getting nice clean tracklogs is less important where the areas are already mostly mapped, and you're just taking geotagged photos; so it's probably not that important for the London to Brighton run, the main route of which got mapped last year.

I had the same problem with battery life on my Nokia N810. I bought one of these: http://www.addonsworld.co.uk/product.php/36108/0 - only 6 pounds and works with AA NiMH rechargeables. It is the same connection on the N95 I believe.

I suspect if you're keeping the device in your pocket, your body is shielding the signal to some extent.
