  1. If you are looking at spending a couple of hundred quid on a GPS then I'd look at either the new Etrex 30 or the Oregon 450. Also for £250 the Oregon 550 will give you a camera.

     

    The Oregon range has a bigger screen than the Dakota, and IMHO a far better unit.

    Handtech have some good prices :)

     

    Most GPS don't have a 'radar' like on a phone, but an arrow. And talkytoaster maps will work on most Garmin units :)

     

     

  2. Have a hunt of ebay, there are quite a few USB/serial adapters which will convert from a type A USB to the Garmin socket on the etrex. Or if you use your cable then a standard USB-serial adapter will do.

     

    Those based on the Prolific chipset work well with the etrex :)

     

  3. Ebay? I searched for 'solenoids' and found lots of manufacturers listings, and all of them had ones that operate 3 to 9 volts.

     

    I haven't even started looking at 'robotics suppliers'. I can see several uses for such things... granted 5 volts would be a better source. However, I don't intend to keep looking much. I did try a nail magnet on two volts and it has fair pull still. So I'm sure it could be done economically if needed.

    There are plenty of pneumatic solenoid valves which operate on 3v, but nothing which would work a catch, apart from maybe a gas solenoid ...that's on the UK version of ebay

  4. We went up via the Pyg Route, but for going back (to Pen-Y-Pass) the Miners Track was a lot easier as the initial decent was quite rapid so the rest was mostly gentle slopes.

     

    Although if I had a baby I'd take the train as it is rocky/loose etc most of the way.

     

    As has been mentioned check the weather as we started out (in Feb) with freezing fog, with thermals and all the cold weather walking gear...but at the top we were in T-shirts in glorious sun!!

     

  5. Yes, click Map This Location and on the sidebar Save As Pocket Query, although you will still be limited to the 1000 cache limit.

     

    EDIT: This loses the text search...so skip that! :(

     

    GSAK or similar would enable you to do this though.

     

  6. As for 3 volt solenoids, they should be possible and available. We used to make decent electromagnets out of nails, wire and a 2 volt carbon cell. That was when I was a kid way back. Since the advent of modern electronics I don't think there is a problem. Or you might have to use a small relay to engage a bigger battery inside (solar charged?). I got the impression that the idea was for a display of information, not a locking system originally, but it's a fair question to ask about solenoids.

    Actually 3v solenoids are not that easy to find...had a quick look on ebay. :(

  7. Another useful google maps feature is using the shift key to show the coordinates of your cursor on the map.

     

    Although this doesn't work with all browsers...not on Opera anyway. You can right click and 'What's here' to show to co-ordinates.
