This is a pain however I'm currently in the process of designing a universal USB power source (using a precision high efficiency DC-DC converter) to energise my array of USB powered devices. So I will be running most gear off rechargeable AA cells of which I have an abundance. > - AFAIK most loggers or phones will get basic GPS reception meaning > less accuracy than specific GPS receivers (but is it important for > logging purposes? I dunno). My GPS enabled phone achieves TTFF quite fast (as I have the ephemeris file regularly auto DL) and the PDOP values are often as low as 1.6 so the precision is quite good and seems to be more than adequate for geotagging. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
