  • GPS Position Jitter: Into the Drink!

    We spent the night aboard BB62 in Camden NJ, with our bikes lashed to a post on the dock. Follow the light-color brick track from the upper-left GPS point across the dock to the black dot marking a memorial stone: we tied up just to the left of that spot.

    NJ2BB-15 is the APRS digipeater aboard BB62 with an antenna high in the superstructure. While I didn’t have any trouble with RF reception, packet collisions pose a problem in a dense urban environment. For what it’s worth, essentially everything in the superstructure is an antenna; the NJ2BB ham shack is a wonder to behold.

    The point-to-point jitter is about 20 meters (18.52, says the GPS info dump), so you’re looking at the un-augmented GPS accuracy of a long-term stationary object. I’m sure there’s a slight registration mismatch between the satellite imagery coordinates and the GPS coordinates, enough to put the upper-left point across the dock.

    If you get the chance, take the tour. The guides are retired Navy, some served aboard BB62, and they take their storytelling duties very seriously. The bunk space, even with air conditioning, is claustrophobic at best; a tip of the bike helmet to you folks who live in these machines!

    [Update: Our daughter discovered three itchy bites in a line across her tummy the morning after spending a night in the bunks. That means BB62 has bedbugs, which you do not want to bring home in your luggage. As a result, I cannot recommend an overnight on BB62, alas. We wish she’d mentioned that before we got home…]

    [Further update: when I reported this to the folks at BB62, they had an exterminator check out the berthing spaces and conclude they have no bedbugs on board. That’s encouraging, but I still heartily recommend that you follow the same decontamination procedures that you should use after all trips.]

    It turned out one rider in our group was an active-duty Rear Admiral who, evidently, could (or should) have supervised the signal gun firing after Colors and Taps. She was traveling incognito, though, and didn’t stand on ceremony.

  • A Night Visitor

    One of those midnight “I heard such a clatter” events: somebody or something was kicking a can all over the driveway.

    Turned out that a raccoon found the stack of carefully rinsed salmon cans in the recycling bin and was puzzling over how to get them apart. Evidently he figured there was something really delicious hidden in there somewhere!

    I had time to fiddle with the camera before he gave up and wandered away on his rounds…

    These are in near-IR “Nightshot” mode with my ancient DSC-F717 and the 1.7X teleconverter. They’re automagic crops from larger frames, walloped en masse with ImageMagick:

    
    for f in *jpg ; do mogrify -crop 1200x900+700+450 -resize 750x563 $f ; done
    
    

    The gritty texture plays hell with JPEG compression, but that’s what the camera delivers. An incandescent spotlight on the driveway contributes the deep shadow, but an ordinary camera (my DSC-H5) produced completely black images, even with the high-power flash setting.

    Memo to self: start keeping the recycling bin inside the garage. But will that just piss off the bears that are moving (back) into the county?

  • Red Squirrel

    I cleaned the compost out of the gutters yesterday and this critter came by to help with whatever missed the wheelbarrow.

    Squirrels and chipmunks show how far you can get with a snappy color scheme and a good PR agent. These things are rodents, pure and simple, but those large eyespots trip your protect-the-baby response every time.

    They’re not particularly well-behaved, either: the chipmunks and gray squirrels have had running battles with them this spring. We think the area’s chipmunks had a population explosion and are shoving into traditional red-squirrel territory. Could get ugly out there.

    Where are the hawks when you need ’em?

  • Chipmunk on High Alert

    The chipmunks are busy cleaning up all the maple seeds from the driveway, but, being chipmunks, they like to stay near a safe spot.

    The absolute best spot to watch for danger seems to be the 4-inch PVC pipe I attached to the garage downspouts: you can see out, but when a threat appears you can run up the downspout!

    [Update: the Cooper’s Hawk just swooped on a red squirrel, missed, and landed on the patio railing as the rodent vanished up the pipe.]

  • Too Many Deer: Another One Bites The Dust

    One Less Deer
    One Less Deer

    Sat down for some tech reading in the Comfy Chair one morning and spotted a lump near the road, at the foot of the deer crossing warning sign.

    While I don’t know if this deer was one of that group, it’s a fair bet.

    There was no freshly smashed glass or broken plastic in the area, which indicates a relatively low-speed collision, the kind where the deer’s legs snap against the bumper and the body rolls over the hood, crushing sheet metal and deforming plastic frippery along the way.

    Many cars display that kind of damage around here. They look as though somebody walloped them with a huge sandbag, which is pretty much the case.

    The animal huggers seem strangely silent about such events. If they had the courage of their convictions, they’d subsidize drivers (and gardeners) affected by the deer overpopulating the area. But, no, they never offer to do that.

    I did find this in the driveway across the street…

  • City Raccoon

    I met this fellow on my way out of a recent MHV LUG meeting; he was up a tree between the library parking lot and the adjacent (and rather busy) gas station / convenience store, minding his own business while performing body maintenance.

    That’s pretty much in the midst of the City of Poughkeepsie, but raccoons have figured out that the livin’ is easy around people. I’m sure he’s also figured out dumpster diving, although he’s likely not looking for discarded electronics…

    Love those eyes!

  • Warming Up on the Flight Line

    Flies on parking meter
    Flies on parking meter

    We stopped in Alfred NY to try out some trikes at The Bicycle Man, went to The Terra Cotta (not that one) for lunch, and parked on a side street. Every parking meter along the street (free on Saturday, fortunately) had an array of house flies parked along the upper edge.

    Perhaps this is the best place for flies to warm up before a flight? Was there a recent hatching?

    They swarmed off the meters as we passed, then settled back in the same way.

    Weird…
