A scrap of fake fur cut to fit the outline of the Sony HDR-AS30V helmet camera and stuck in place with a square of double-stick foam centered above (or below, in the normal orientation) the lens:
Snippy remarks about what that looks like will not be tolerated, m’kay?
It reduces wind noise to an occasional rumble from strong gusts and even those don’t crush the AGC. My side of our radio conversations became clearly audible, as did shifters clicking and gravel crunching. There’s still plenty of noise, but now it comes from actual sound sources that don’t overwhelm the amp.
A layer of ordinary adhesive tape still covers the mic pores and the fur’s fabric backing extends over the tape, so the combination must muffle the sound at least a little bit. Given the source material and my hearing, it’s Good Enough; Golden Eared Audiophiles need not apply.
I also cannot detect any difference between the left and right audio channels, so the stereo separation at 15 mm isn’t worth much. I don’t know if the camera swaps the audio channels in video flip mode; that would be a nice touch.
The hairs extending outward beside the lens occasionally blew into view, so a haircut is in order:
Perhaps a clip that snaps over the skeleton frame to hold a neat patch of fur in place without adhesive on the camera body would be even better?
Here’s the solution to creaking SPD pedals due to hardened shoe cleats gritting on hardened pedal latches:
Those are carefully shaped snippets of open-cell foam tucked around the springs under the movable latches, loaded with a few drops of penetrating oil, and ridden for several months. Nary a squeak or grinding sound has emerged: far better than the results after I added a drop of oil whenever either of us heard that sound.
Similar snippets tucked under the forward latch fell out without affecting the results, from which I conclude:
- The front latch doesn’t squeak
- The foam on the other side is Close Enough
- Penetrating oil oozes into a thin film over the whole pedal
The cleats don’t quite touch the ground when we walk, so we’re not leaving oily footprints.
Should I ever install new pedals, I’ll see if a larger foam block can span the gap between the front latch on the top and the movable latch on the bottom.
With the Sony HDR-AS30V in its skeleton frame atop my bike helmet, the audio track for all my rides consists entirely of horrendous wind noise. You can get an idea of the baseline quality from the sound track of a recent Walkway Over The Hudson crossing.
The camera has two mics, although I’m not sure 15 mm of separation really produces meaningful stereo sound:
Note that two of the five pores on each side are closed flat-bottom pits. As with earbud vents , it must be a stylin’ thing.
I added a rounded pad of the same acoustic foam that forms an effective wind noise buffer for the boom mic:
That reduced the overall noise load by buffering direct wind impact, but non-radio conversations remained unintelligible; there’s just too much low-frequency energy.
Surprisingly, closing the mic pores with ordinary adhesive tape didn’t impair the audio in a quiet room:
Out on the road that’s even better than foam over open mic pores; I think it reduces the peak volume enough that the internal compression can regain control. Sticking the foam pad over the tape slightly reduced the noise during high-speed (for me, anyhow) parts of the ride, but didn’t make much difference overall.
The wind noise remains too high for comfort, even if I can now hear cleats clicking into pedals, shifters snapping, and even the horrible background music when I’m stopped next to the Mobil gas station on the corner.
The NYS DOT’s original planning documents said that roundabouts / rotaries weren’t optimal for pedestrians or bicyclists or large trucks, but, because DOT likes rotaries, that’s what they built on Raymond Avenue. However, they didn’t relocate the drainage lines under the road and left some catch boxes in awkward spots.
This Google Street View image from a few years ago shows the College Avenue intersection from northbound Raymond Avenue, with the catch box in the lane:
Raymond is basically the only bicycle route into Arlington from the south and has “shared roadway” signs, but the design flat-out doesn’t work for bikes and the implementation leaves a lot to be desired.
Here’s what it looks like from the bike:
Note the deteriorated asphalt and longitudinal cracks near the white fog line next to the curb. That forces bike traffic another few feet into the deliberately narrowed traffic lane at the entrance to the intersection.
Mary’s about as far to the right as practicable (that’s a legal term):
I’m angling over from the middle of the lane, because, unless I take the lane, motorists will attempt to pass us in the rotary entrances. The asphalt on the far side of the box has subsided several inches into a tooth-rattling drop, you can see the crevice adjacent to the right side of the box, and I know better than to cross steel grates while turning.
Notice that the Google view shows four bollards marking what DOT charmingly calls the “pedestrian refuge” in the median, but only two appear in my pictures. NYS DOT recently removed half the bollards from each refuge and relocated the remainder, apparently to reduce the number of street furniture targets. Early on, they were losing one bollard per intersection per year, but that’s slowed down now that they’ve stopped replacing smashed hardware.
It was never clear to me why putting nonreflective black bollards a foot or two from the traffic lane made any sense, but that’s how it was done. Most of the relocated bollards stand close to the center of the median, so maybe it didn’t make any sense.
Anyhow, bikes can’t stay too far to the right after the box, because the asphalt has crumbled away in furrows around Yet Another Crappy Patch:
That’s pretty much the state of the traffic engineering art around here. A while back, the NYS DOT engineer in charge of the project assured me it’s all built in compliance with the relevant standards.
It’s worth noting that Mary’s on the Dutchess County Bicycle and Pedestrian Advisory Committee, so we volunteered to count cyclists and pedestrians on Raymond a few months ago. When I say that we’re essentially the only cyclists riding Raymond Avenue, we have the numbers to back it up. Everybody else rides on the sidewalks, despite that being of questionable legality and dubious for pedestrian safety, because, well, you’d be crazy to ride in the shared roadway.
The Sony HDR-AS30V helmet camera can record about 5.5 h of 1920×1080 60 fps video on a 64 GB Micro-SD card, but a single NP-BX1 battery provides a 1.5 h run time, tops. Having had a good experience with the previous Wasabi batteries, I picked up three more and ran all six through the battery tester:
The red curve is the Sony OEM battery, the two lower curves are the Wasabi batteries from January, and the upper three come from the new Wasabi batteries. All in all, they look good to me.
These curves aren’t directly comparable to the older ones, as I’ve bumped the discharge to 500 mA to better match the actual camera load. These worked out to about two hours apiece, so the camera must draw around 600 or 700 mA.
The Wasabi batteries deliver a higher voltage than the Sony OEM battery over nearly all of the discharge curve. The older ones delivered almost exactly the same run time, which leads me to believe the camera cuts off at 2.8 V, too, with a boost power supply extracting all the energy under the curve.
I suppose a 1.5 h run time makes sense for downhill skiiing, but it’s painfully short for bike trips.
After years of neglect, an NYS DOT crew started a really nice repair job on the inside edge of the curve just north of our house. They milled out the deteriorated road surface, cleaned out the debris, and laid in a patch flush with the road surface. That’s quite unlike their usual shovel-some-cold-patch / hand-tamp / drive-over-it process, made familiar everywhere else around here.
Unfortunately, for unknown reasons, they didn’t fill in the last two feet of the milled-out trench, leaving a tooth-shattering pair of perpendicular edges exactly where you’d least expect them:
Ran out of asphalt? Lunch break? Called off to another emergency? We’ll never know.
I sent a note, with that picture, to the NYS DOT Bicycle & Pedestrian Coordinator, asking what happened; perhaps they planned another layer atop the whole curve to seal the rest of the cracked pavement?
The next day a crew filled in the hole, which I find far more than coincidental.
Although it’s better than it was, there’s now a joint that will deteriorate more rapidly than the uniform asphalt layer they should have created.
We’ll take what we get…
- Christie’s has licensed their brand to local realtors
- Such licensees / franchises / whatever are locally owned and operated
- Realtors make money only when they sell a property
- Sometimes, you must sell a property’s upside potential
- Ya gotta market what ya got
Even keeping all that in mind, I think this property devalues the Christie’s brand:
IIRC, it was a roadhouse eatery, back in the day, has been many things since then, and hasn’t been much in recent years.
