I could probably get something cheaper on ebay.
I'm doing something similar with olimex components (and an arduino-like board instead of the raspberry). 12.95 EUR https://www.olimex.com/Products/Duino/AVR/OLIMEXINO-32U4/ 39.95 EUR https://www.olimex.com/Products/Modules/GPS/MOD-GPS/ 3.95 EUR https://www.olimex.com/Products/Modules/Interface/MOD-SDMMC/ 5.95 EUR https://www.olimex.com/Products/Power/BATTERY-LIPO1400mAh/ That's 62.8 EUR, which is in the range of the turn-on-and-forget GPS loggers (like the iBlue I had that is currently dying) I could find on amazon. Additional parts (just a bit of protoboard, headers and a switch) will come from my parts stash and fit in the 10-15% overhead that I allowed in the budget for the fun part of the project. :) The main advantage on an android phone [1]_ to me, is the fact that it can almost be operated while driving (hit the switch while stopped in traffic just before you decided to try a crazy alternative route, and it starts logging :) ) .. [1] which last time I've checked started closer to 100 EUR than 50EUR in our supermarkets :( Another advantage is the modularity: while I'm non using it for logging I can reuse the most expensive part (the GPS, of course) for additional prototypes / one-time projects. I also hope that by changing parts I will be able to use it for longer than my old logger lasted. -- Elena ``of Valhalla'' _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
