    NFC tags, anyone?

    in GPS technology and devices

    Posted · Edited by eusty

    I'd be interested too :)

     

    The issue I have is that the only ruggedised tags I can get are Ultralite, so restricted to 46bytes.To fit the data on a tag with a single identifier you can only have a precision of four decimal places.

     

    geo:38.8977,-77.0366?q=38.8977,-77.0366(1)

     

    This means a resolution of 22ft...which really isn't enough :(

     

     

    EDIT: Going to try some of these as see how they stand up outside.

    OK...I lied!!

     

    I had a couple lying about so I tried it with 8 point precision...and everything worked fine, no idea why it didn't last time :huh:

     

    The geolocation header is 10 bytes, but if you add a comment it increases to 22. So you can use Ulralight for geolocation, although realistically you need NTAG203 to add much of a comment.

     

    Which handy as you can use these which makes fixing easier :)

    You should be able to get geolocation to work with Ultralight (46 byte) tags. You don't need that much precision (8 decimal places should be more than sufficient) so we're looking at under 40 bytes. You probably won't be able to store a name though. If you encode it as a text string, "N xx xx.xxx E xxx xx.xxx" is only 24 bytes, + 7 bytes header = 31 bytes, giving you space for a short text description.

    Mmmm..yes you are correct..Ultralight! I couldn't remember what they were called so just scanned on and it came up as type 2 :unsure:

     

    I tried shortening the precision to reduce the data size, but I can't remember if they didn't encode or you couldn't read them as geolocation tags. The only way I found to work was to use NTAG203 and select 'use current location', but it maybe a shortcoming of the phone/app etc

     

     

    Torch for late afternoon/night caching

    If you want a P7 then here, but if you want a 'proper' torch then get one of these.

     

    I used to think my P7 was a good torch until I got one of these, well worth the money :)

     

    The fenix looks good, but I'm not keen on the idea of having to use specialist batteries when the Lenser uses standard AA batteries.

    The 18650 batteries are pretty standard, basically they stick a few of them together to make most laptop battery packs. Being Li-Ion they last for ages and a quick to recharge :)

     

    Every time I use the torch (like this evening) I smile to myself as it's that good!

     

    Geocaching Map Enhancements

    I had the same problem at first

    You need to click on the "i" icon on the bottom left of the map (turning it blue), then left click on the map, next click on show labels

     

    Hope this helps

    Although this doesn't work using Opera :(Would it would be a better idea to put it on the main option screen?

    However, I'm considering a GPS as they are probably more robust and waterproof.

     

    You bet they are! Waterproof to 1m :)

     

    If you like the OS maps then they are available on the eTrex. The 25k is pretty expensive although there are ways of putting them on the GPS with some hacking. 50k is more reasonable and as been mentioned OSM maps are pretty good.

     

    I'd be temped to look at the Oregon, or better still the Montana, as the screen resolution is better than the eTrex.
