Consumer electronics designers seem to favor low- or no-contrast markings, with this USB reader falling on the vanishing end of the spectrum:
I poke the MicroSD card from the AS30V helmet camera into the smaller slot on the top surface, but, contrary to what’s revealed by the camera’s flash, the slot is a black-on-black target.
Well, I finally fixed that:
Although white tape surely would have sufficed, the roll of fluorescent red came to hand and that’s what it’ll be. The CompactFlash and Memory Stick slots on the front don’t see much traffic and have better access.
I slapped tape on case, trimmed the slots with a razor knife, and declared victory.
Back in the day, John Forester’s Effective Cycling defined how vehicular bicycling should be done; our now-fragile comb-bound 1980 Third Printing of the 1978 Third Edition still has a place of honor on our bookshelves. I recently discovered his analysis of how traffic signal timing should work online, which says I’ve drawn the wrong conclusions from my observations of the absurdly short green / yellow / red cycle on Burnett Blvd at Rt 55, just in front of NYS DOT’s Region 8 headquarters.
The phasing sequence that is required by current traffic law is as follows:
1. Green, which may be very short when only one vehicle is waiting
2. Yellow, of only sufficient duration to allow a stop from maximum legal speed before entering the intersection
3. Red (a 4-way red), for sufficient additional time for traffic to clear the intersection before the conflicting green appears.
With that in mind, here’s how his analysis stacks up against one of our recent trips through the intersection. The four-digit number in the picture titles gives the time in frames at 60 frame/sec.
We’re stopped one car length behind a long trailer of paving equipment sporting an Iowa license plate. The driver has stopped with the trailer straddling the lane divider line, so we cannot determine which way he will turn. Because we no longer trust turn signals, despite the trailer’s blinking left signal, we will not pull up beside it in the right lane.
Frame 0127, T = 0 s, Δt = 0 s: The signal has just turned green:
Frame 0264, T = 2.28 s, Δt = 2.28 s: The trailer has started moving and Mary is rolling behind it, with her foot just coming off the ground:
Frame 0721, T = 9.9 s, Δt = 7.6 s: The signal turns yellow, after DOT’s additional five seconds of green; previously, we had five seconds and would have been able to stop. We’re accelerating as hard as we can, but Mary has barely passed the stop line:
Of course, entering an intersection on a stale yellow is undoubtedly unwise. It is not so unwise for someone traveling fast, because that person may well clear the intersection before the conflicting traffic starts. It is much more unwise for someone traveling slowly, but it is done and it is lawful.
We’ve traveled about three car lengths in the seven seconds since the trailer started moving. Our bikes will sometimes trigger the signal if we’ve stopped in exactly the right spot over the unmarked sensor loops, but we have never observed our bikes retriggering the signal to lengthen the green or yellow phases as we ride through the intersection.
NYS DOT apparently expects us to stop abruptly when the signal goes yellow, wherever we may be with respect to the stop line and regardless of how fast we may be moving. In fact, given what you’re about to see, we’re expected stop on green to ensure we can start from the stop line during the next green signal.
Frame 0983, T = 14.2 s, Δt = 4.4 s: The signal turns red. The trailer is visible on the left, beyond the median signage, but we haven’t reached the middle of the intersection. I’m lined up with the rightmost lane of westbound Rt 55 and Mary is about in the center lane. The white car on our right is stopped, the black car is slowing to a stop:
Frame 1101, T = 16.2 s, Δt = 2.0 s: The opposing signal goes green for Rt 55 traffic, while we’ve barely reached the middle of the intersection:
Frame 1205, T = 18.0 s, Δt = 1.8 s: I’m lined up with the median, Mary’s in the center lane of eastbound Rt 55, putting us squarely in front of drivers who may be unable to see us through the stopped cars. The drivers to our left are, fortunately, waiting, unlike a previous crossing:
Frame 1440, T = 21.9 s, Δt = 5.7 s: After 22 seconds, we’ve cleared the intersection and are proceeding eastbound on Rt 55:
Forester observes the all-red phase must be lengthened to allow cyclists to clear the intersection. Right now, two seconds isn’t enough. Ten seconds would suffice for a pair of reasonably fit, albeit aging, cyclists.
This system fails to provide the required safety in the case of bicycles for three opposite reasons.
1. Bicycles are small and are harder to see. In particular, the most visually impressive part of the bicycle and rider is low down where it is easily shielded from view by the hoods of motor vehicles. Sometimes the only part of the cyclist that can be seen by drivers waiting at the stop line with other vehicles on their left is the head of the cyclist.
2. The cyclist crossing a typical intersection is close to the fronts of the line of cars waiting at the stop line on the cyclist’s right. This is not good judgement on the part of the cyclist, but so much emphasis has been put on staying far right that this position is typical.
3. The cyclist who is traveling slowly, or, more importantly, is starting from a minimum-duration green, is barely into a wide intersection when the conflicting green appears.
The result is a car-bike collision as one of the vehicles in the lanes nearest the curb starts up, or speeds up, and hits the cyclist who suddenly appears in front of it.
I’ve had a DOT engineer tell me, sneeringly, that they don’t design facilities for “professional cyclists”, which commuting to work evidently made me; he was not, however, a “professional driver” even though he used a car for a similar purpose. It’s obvious DOT doesn’t design facilities for “ordinary” cyclists, either, and the evidence suggests they don’t design facilities for cyclists, period, full stop.
The Anker 13 A·h USB power pack on the rack provides juice for a week’s worth of rides, letting the M20’s internal battery keep its clock & settings alive between rides. I recently forgot to turn on the USB pack and discovered the camera shut down just after I cleared the end of the driveway.
As you should expect, the battery had swollen so much its pull tab … pulled off … when I tried to extract it:
So, we begin.
Pry off the trim ring around the lens by jamming a small screwdriver in any of the three slots:
Then pry off the entire front panel:
Thereby exposing the battery’s rectangular protrusion and three contacts next to the optical block:
Avoid shorting the brass terminals with, say, a small screwdriver, while shoving the battery out of the camera until you can grab it with your fingers and haul it out the rest of the way:
Yeah, that puppy looks all swoll up:
Remove the all-enclosing label to reveal the bag inside:
Pull the bag out to reveal the protection PCB:
Snip the wires and salvage the case against future need.
I bought the camera with three batteries, all three of which are now similarly swollen. I also got two official SJAM batteries with an official SJAM charger; both of those batteries seem to be in fine shape. I expect the codes on the five bags would reveal two different lots, but I’m not going to sacrifice a nominally good battery to find out.
All three swollen battery bags show the same BEP 782633PL lot code and 1704 date code. I bought everything in January 2018, so those batteries had been sitting on the shelf for the better part of a year. Maybe that’s why they offered a “deal” for two spare batteries along with the camera?
Installing one of the unswollen batteries, reconfiguring the camera’s settings & clock, and giving it a charge from the Anker USB pack put it back in operation.
Our southbound bicycling routes take us through the intersection where Vassar Rd becomes NY Rt 9D at NY Rt 9. This is a large intersection:
It’s worth noting that Rt 9D and Vassar Rd are also NYS Bicycle Rt 9., so bicycle traffic is expected, if not precisely welcomed.
We’re traveling south on Vassar Rd, stopped in the right-hand lane (in the upper right of the picture). Eventually, the signal turns green:
The traffic to our left starts moving, we start pedaling, and ten seconds later the signal turns yellow:
The traffic hasn’t cleared the intersection, either, but they’re moving faster than we are. The first distance marker on the map shows we’ve traveled 85 feet at an average 5.8 mph from a standing start.
After another five seconds, we’ve traveled 80 more feet (at 11 mph!), almost the far side of the intersection. Which is a good thing, because the signals on Rt 9 have already turned green and vehicles are accelerating toward us.
I cleaned the wound, filled it with silicone rubber, topped it with some duct tape, and it’s still holding air after a 13 mile ride. I think the gash cut through the rubber tread and SmartGuard layer, but didn’t affect the cords in the tire carcass, so keeping further road debris out of the gash should let the tire wear out more-or-less normally.
Putting duct tape on the tread will certainly help …
