Arduino DRO

Well, it didn’t work :) At least I couldn’t get it to work. The issue I had was in repeatability, I’d made a little harness to move the mouse forwards and then return it to the same spot but the values I was receiving weren’t consistent making it useless as a tape measure. When mousing these slight variations wouldn’t be important but it was a deal breaker for this idea. Ah well :)

    Hi.

    I have no idea what this was about but I was wondering about the tape measure comment.

    It would be extremely useful to have a mouse feature that would ping a circle on the monitor.

    I use weather charts a lot, also other maps from various sites. If I could ping a circle of known radius over the screen using the mouse, that would be unimaginably useful.

    Here is an example:

    So, let us all take for example the Low 974 mb some 17 degrees NW of it at the moment: http://meteonet.nl/aktueel/brackall.htm

    It is nicely centred at 60 N 35 W and playing Hickory Dickory with one going ashore at Norway at about 15 NE (969 mb, 66 N 10 W.)

    So long as the Low maintains that distance, things should be nice
    here. But earth-shattering elsewhere.

    Here is another site that some means of gauging distance would be useful: http://weather.unisys.com/images/sat_sfc_map_loop.html

    Imagine just pinging on one of those air pressure centres and being able to say roughly how far they are apart in degrees. Ditto these sites:

    http://www.hurricanezone.net/
    http://satellite.ehabich.info/index.html

    This last one does have rings but not sufficiently large enough to guess distances apart.

    I know that the idea of plotting circles on a cartograph is hardly ideal but it would save me hours messing with a globe and compass.
