Coopers Hawk

Coopers Hawk on pole

The hawk who’s been keeping the chipmunks and squirrels under control paused for a moment atop the utility pole out by the garden. He left instantly after I appeared around the edge of the roof, leaving me no time to fight the camera automation into a better exposure, but it’s good to know he’s on patrol.

A few months ago he had a squirrel in a Mexican standoff inside a pine tree, circling the trunk amid all the branches. Eventually the squirrel made a break for it, got about five feet out from the trunk, and wham that was the end of the story: once those claws go in, they don’t come back out.

Notice the noonday sun refracted through his cornea onto his upper cheek (or whatever it is that birds have there). This was with the 1.7X tele-extender on the Sony DSC-H5 zoomed in pretty nearly all the way; if it weren’t for all fringing and blown highlights, it’d be a neat picture.

Dockers Sock Sizing

We picked up two packs of Dockers socks a while ago and after running them through the washer, I found this interesting situation:

Dockers sock size variation

The gray sock in the middle shows that I should buy socks somewhat more often, but the socks on either side came from two packs with identical labels. Well, identical except for one tiny detail (clicky for more dots):

Dockers sock labels – front

I don’t know which sock came from which pack, but I admit to a suspicion. They’re stretchy and both “sizes” fit about the same, so maybe it doesn’t matter.

[Update: It does matter. Those small socks became really snug after a few months.]

Oh, in case you were wondering, the pre-printed package reads “3 Pair $12” under that “3 Pair” sticker, with the price obliterated by hand with a marker. The current price is $14, conveyed by another sticker on the back atop the pre-printed price on the UPC barcode sticker. I don’t know if the store raised the price just in time for the sale, but I admit to a suspicion about that, too.

Harbor Freight Multi-Use Transfer Pump: What’s It Good For, Again?

The front of the label giveth (clicky for more dots):

Harbor Freight Pump

The bottom line says “Ideal for changing oil and siphoning gas”, which is what you’d expect.

However, the back of the label taketh away:

Harbor Freight Pump – Warning

If it manages to empty three small engine tanks and doesn’t immediately dissolve in gasoline, I’ll call it a win.

Sheesh and similar remarks.

Cellular Slug

Perhaps taking a cue from the Cellular Toad, a slug took up residence in one of Mary’s transplant trays:

Unlike the toad, this one didn’t live to tell the tale…

Lenovo Mini Wireless Keyboard: Readable Power Switch

The backside of the Lenovo N5901 Mini Wireless Keyboard (which arrived with the aforementioned Q150) has a black-on-black power switch with ON and OFF legends (yes, I think they’re backwards, too) embossed in the matte black case: under anything less intense than enhanced interrogation lighting, you (well, I) can’t determine the switch position.

Of course, the myriad certifications / ratings / labels required for compliance with all the regulations are perfectly legible:

Working a dab of white correction fluid into the letters makes them blindingly obvious; the smudges around the letters will wear off in short order.

I should probably add a bit of white to the switch background as well.

MGE Ellipse 1200 Battery Arrangement

The SLA batteries in the MGE Ellipse 1200 UPS finally gave out. This picture shows how they’re arranged inside the box:

MGE Ellipse 1200 UPS – battery arrangement

They’re 12 V 5 Ah batteries that are about 12 mm thinner than the garden variety 7 Ah batteries you can get everywhere; they’re not the same size as the generic 5 Ah batteries you might think would work. Of course, there’s not enough room inside the stylin’ case for the larger ones, either. I’m thinking of using fatter batteries anyway and putting a belly band around the gap. Maybe an external battery box with a chunky cable burrowing through a hole in the UPS case?

For what it’s worth, APC absorbed MGE a while ago (so the MGE website redirects to APC), got Borged by Schneider, then spat out MGE’s consumer grade UPS units to Eaton. You won’t find any of that documented anywhere, but here’s the response from APC after I didn’t find this UPS on their list:

I do apologize; when APC was acquired by Schneider Electric, the single phase UPS line that MGE once offered was sold to Eaton. Eaton now provides support for the MGE single-phase products. We do not sell batteries for these models. You will actually need to contact Eaton for further assistance regarding the MGE Ellipse units. You may click on the link below to go to Eaton’s website:

The Eaton website does have a battery replacement for this one, but sporting the dreaded “Contact us for price” notation. Given that I got the UPS cheap-after-rebate, I’m thinking maybe this isn’t worth the effort.

Parking Advice: Avoid Drive-Through Spaces

After driving for five hours I’m never at my best, so I parked with atypical abandon at the motel: on the downhill side of a pull-though parking space. Usually I park off to one side of the lot, directly under a lamp that lights the car and shadows the interior, with the hatch backed against the pole. I claim the stupid excuse.

The next morning we hiked out for breakfast and returned to find emergency vehicles scattered all over the motel’s lot. Even from a distance, we knew this might not have a good outcome for us: that’s our van going nose-to-nose with the EMS Medic’s SUV:

Up close, the situation turned out to be much much much better than I expected:

EMS Medic parking – bumper detail

The siren was just kissing the front bumper of our van. I think the SUV rolled forward an inch when they released the brakes after slapping the tranny into Park and bailing out.

For what it’s worth, those fancy pusher bars on the front must be strictly for looks, because the siren & its control box really do stick out far beyond the bars. At the first serious contact they’ll crush back into the grille and do about a kilobuck worth of damage to the front end.

I think the driver wasn’t fully aware of how much snout that SUV has. It looks to be shiny-new, so perhaps this was the first close quarters parking experience:

I left a polite note on the driver’s side window pointing out that another two inches would mean we’d be filling out paperwork until noon.

They were gone by the time we left. The siren snagged the corner of the license plate and bent it out as they departed, but that’s not the first bend in that particular bit of sheet metal.

If any of you have a friend on the York PA Medic / EMS staff, give ’em a friendly heads-up for me, OK?

Memo to Self: Always park off to the side, dammit!
