Anker MicroSD Card Adapter Speeds
Posted by Ed in Electronics Workbench, Photography & Images, Recumbent Bicycling on 2019-04-14
According to its description, the Anker USB 3.0 card reader can handle both a MicroSD and a standard SD card at once:
Simultaneously read and write on two cards to save yourself the effort of constant unplugging and re-plugging.
Which looks like this:
After you get used to inserting the SD card downside-up, it fits perfectly. The Kapton tape on the MicroSD card eases extraction from the still finger-dent-less M20 camera mount on the back of my Tour Easy ‘bent.
Plugged into a USB 3.0 port, my file extractor script chugs along at 25.9 MB/s, taking about 18 minutes to transfer 28 GB of video data.
Splurging another eleven bucks for a second reader produces this setup:
After plugging both readers into adjacent USB 3.0 ports, the script transfers files at 46.6 MB/s and copies 28 GB in 10 minutes.
So, yes, the reader can handle two cards at once, but at half the speed.
Not life-changing, but it shows why I like measurements so much …
Sharing the Road on Raymond Avenue
Posted by Ed in Recumbent Bicycling on 2019-04-07
This time, I neglected to give my “We’re taking the lane!” signal, whereupon the driver behind us assumed we would all fit into the roundabout / traffic circle at Vassar’s Main Gate:
Raymond Avenue’s original “standards compliant” design has undergone some revision during the last few years:
The brace of black bollards centered on the median at the “pedestrian refuge” now replace the original quartet of illuminated, albeit non-reflective black, bollards, after errant drivers successively destroyed them.
There’s apparently no standard governing the placement or depth of drain grates along the right edge of the lane, nor the amount of gravel and trash allowed to accumulate to the right of the fog line:
Mary is just barely clearing the grate, I’m moving leftward to ensure I’m the first one to get hit. Fortunately, common sense broke out:
We got through the traffic circle without further contention and continued on our way.
Getting squeezed into a traffic circle happens often enough to show whatever NYS DOT uses as a “design standard” doesn’t include pedestrian or bicyclist safety as measurable quantities.
As we all know, anything you don’t measure doesn’t happen.
Broken Spoke
Posted by Ed in Machine Shop, Recumbent Bicycling on 2019-04-06
On the drive side, of course:
I’d noticed some brake drag on our last few rides, but forgot to check until I saw the rim wobble while extracting images from the rear camera.
It’s a lot easier to fix in the Basement Shop than on the road. After nigh onto a decade since replacing the last broken spoke, perhaps this is a harbinger of doom to come.
Memo to Self: spoke tension is now 20-ish on the drive side, 15-ish on the left.
Monthly Science: Weight
Posted by Ed in Home Ec, Recumbent Bicycling, Science on 2019-04-01
We’d been eating a “healthy” high-carb / low-fat diet, which produced the more-or-less expected 1 lb/yr weight gain over the course of three decades. Given that we eat about 106 Cal/yr, being off by a mere 0.3% seemed fixable, but we were always hungry while trying to cut out calories.
In April 2016, we decided our tummies had come between us, so we switched to a mostly ketogenic diet (clicky for more dots):
Having a Master Gardener in the family complicates dietary choices along the ketogenic axis, but Mary raised more green-and-leafy veggies, less squash-and-corn, and we keto-ized our meals reasonably well. Moderation in all things works fine for us, so losing 25 pounds at about 1 lb/week wasn’t particularly stressful.
Continuing through 2017, you can see how regular bike riding season affects winter bloat:
Our cycling vacation in July 2018 produced a blip, but the rest of the riding season worked as expected:
It’s straightforward to crash-diet two dozen pounds, but maintaining a more-or-less stable weight for the next two years suggests we’ve gotten the annual calorie count about right. FWIW, my bloodwork numbers sit in the Just Fine range, apart from the somewhat elevated cholesterol level typical of a keto-ized diet.
Starting in late 2018, however, a stressful situation of a non-bloggable nature (at least for a blog such as this) produced an unusually high number of road trips, motel stays, and generally poor dietary choices:
The situation now being over, our lives / exercise / diet will return to what passes for normal around here and my goal is to lose another 10% of my current body weight, ending at 150 pounds, by the end of the year. In round numbers, that requires losing half a pound = 1700 Cal/week, 250 Cal/day. Not power-noshing an ounce or two of nuts a day should do the trick.
If it makes you feel more science-y, you can use the NIH Body Weight Planner, but it produces about the same answer: knock off 300 Cal to lose weight, 250 Cal to maintain it, at essentially the same exercise level as before.
We’ve been recording our weights as dots on graph paper every Saturday evening for the last four decades, so I know for a fact I averaged 148 pounds when I wore a younger man’s clothes. I’ll re-post the 2019 chart, adding four dots every month, during the rest of the year.
This way, you can help keep me on track … [grin]
A Bounteous Tobacco Harvest
Posted by Ed in Oddities, Recumbent Bicycling on 2019-03-30
Spotted on a utility ride to a local shop:
We decided an employee of the adjacent “nail spa” has been making the best of a bad situation.
If it was easy to quit, there’d surely still be a few smokers …
Dutchess Rail Trail: Access Gate Control
Posted by Ed in Oddities, Recumbent Bicycling on 2019-03-29
Five different agencies can drive through the Dutchess Rail Trail’s Overocker Rd trailhead vehicle gate:
Well, four of them can, because whoever snapped the barely visible small lock around the long-shackle lock (horizontal, to the right) is SOL:
Perhaps they’re from the DC W&WWA?
The last time we rode past the Diddel Rd trailhead, there were zero locks on the (unchained) vehicle gate; evidently somebody forgot to relock the gate on the way out.
Turtles!
Posted by Ed in Photography & Images, Recumbent Bicycling on 2019-03-17
Spotted in Lake Walton on an out-and-back ride to the Hopewell Junction Depot end of the rail trail:
Mary counted & guesstimated fifty turtles in the backwater.
They’re the snuggliest turtles I’ve ever seen:
Taken with the Pixel XL at maximum zoom, hence the gritty overpixelization.
