Silver Case

Google Maps now has a mode for bicycling directions. It doesn’t work in Singapore yet, so I tried it on the Murrysville-to-Corsica route. Click on the map to be taken to the full directions.

Overall, the directions (both by car and by bike) are odd, or at least not what we’d customarily do (follow state 66, basically).

The bike version really diverges once I reach West Kittaning. Rather than going northeast, up through Goheenville and Distant, it keeps running north, along the river. Maybe it prefers along the river because the grade is not going to be as severe? That little detour along the river, for instance, adds 15km to the trip. It also avoids Olean Trail for some reason. Maybe it tries to avoid gravelly roads too?

The estimated time is also bizarre — 8 hours to ride 115km. It thinks I average 14km/h? ahhaahh not quite. Unless I really underestimate the altitude climb required for this ride, I don’t see why it would be so slow. On rides half as long I can pretty easily manage 27km/h solo.

Anyway, maybe I’ll try some version of the alternative Google bicycling directions when i am in the USA this summer. Certainly stretches of 66 are not that nice for cycling (no shoulder, two-lane highway). Maybe the riverside run would be nice.

Luke, Ling, Woei, and I did a short bike run for breakfast today. I was riding my Favorit fixed-gear bicycle. On the way back heard a repeating noise. Unusual. Single-speed track-gears make almost no noise, because there are no freewheels or derailleurs. When I looked down I could see a wobble in the rear tire, so I figured a spoke broke.

When I inspected closer, I saw that the spoke was fine, that in fact the cheap aluminum spoke nipple had snapped its head off. At least that will be easier to fix, but no wonder quality wheelbuilders refuse to use aluminum nipples on wheels. That wheel has literally seen less (far?) than 100km on it.

The wheel issue reminded me that I needed to have a follow-up appointment with my road wheel I rebuilt back in January. It is running true but I was more interested in the spoke tensions and how they’ve held up since I first built the wheel.

The results look pretty good. Not perfect, but liveable.

When I did the math

January Measurements:

Drive Side tension (mm of deflection) averaged 1.85 with a std dev of 0.08mm (or 4.17%)

Non-Drive Side tension averaged 1.22 with std dev of 0.08 (6.76%)

March 2010 Measurements

Drive Side: 1.82mm average with std dev 0.09 (4.80%)

Non-Drive 1.13mm average with std dev 0.10 (8.60%)

So the wheels loosened up a bit and slackened a bit, but still quite ok. The worst drive-side spoke deviated by 10%. On the non-drive side, I had three spoke unacceptable (-14%, -20%, +11%).

This should be quite fast and easy to tune up, and then I’ll check again in a couple months. I guess I’ve probably ridden a little over 700km on this wheel so far?

Interesting, I was talking to Brian Roddy, president of Rolf Wheels at the NAHBS. I told him that my friend had been using a Rolf wheel forever and claimed it was the strongest wheel he’d ever used. Brian told me that how they built the wheels is (1) build the wheel (2) press the rim from each side with 400lb force (3) re-tension (4) press again with 400lbs (5) do a final retensioning. That means the spokes are really well seated in. Pretty cool, and it makes results. I guess I make some sort of jig to press wheels like that myself — just need a big lever and a proper die to press against it.

This morning I picked the first (and so far only) tomato that matured from the big pile of seeds we harvested in Italy last autumn. If I wasn’t leaving for the North American Handmade Bike Show tomorrow morning, I probably would have left it longer on the vine to ripen, but alas…

First I was like

But then I was like

A couple months ago I “won” an eBay auction for a first-edition printing set of Edward Gorey’s “Helpless Doorknob: A Shuffled Story.” It’s a set of cards meant to be shuffled into a story.

Enjoy tonight’s (entirely random) story.

What is it about Tokyo’s Hotel Okura?

It’s got a worse location than the Peninsula. Rooms almost spartan compared to the Ritz-Carlton. Far more dated than the Grand Hyatt.

But I still love it. I think because it’s so spare and pure. It’s a top 1965 Tokyo Hotel preserved and maintained immaculately. When I’m sitting in the lobby it feels like Frank Sinatra’s entourage could pull up to the front door at any minute. The interior design of the hotel is totally consistent and totally classy. I spend almost no time in the hotel room, so I don’t do much beside appreciate the bed. And I certainly appreciate the hotel costing may one-half what I’d spent at any of the other three. (though maybe this will change — Ginza was a ghost-town for several of the bars and restaurants we visited there — the economy does not feel strong.)

My productivity has been shit for five days. What little activation energy I have to get anything done burns off when I turn on NetNewswire and start reading any of the hundred different newsfeeds I subscribe too. Yep, plenty of interesting stuff on there, and lots of new ideas for things to work on, but it’s like drinking from a firehose. I should shut the damn thing off and concentrate on lapping some puddles. Ugh.

I’m sitting here with my $10 Ikea lapdesk using my computer in the bedroom while Ling watches some horrible reality tv show with Bruce Jenner playing the part of Ozzy Osbourne and some other woman who looks like Sharon Osbourne. The kids look better the fat Osbourne kids at least.

I was surprised by his massive house. Lots of Wheaties residuals I guess. Then I made a remark that a Bruce Jenner reality show is scraping the barrel bottom.

Ling says, “this isn’t about Bruce Jenner, it’s about the Kardashians”   

“Huh? Then why is Bruce Jenner in their living room?”

“Because he’s the step-dad,” she explained.

Ooops, my bad!

My only comment? Bruce Jenner is Frank Black

I rode my Brompton to the machine shop today. Michel, Sulaiman, and I were doing a non-invasive teardown analysis of it. The final conclusion is something like

It is an elegant design that has clearly been refined over many years. Almost every detail and part on the bike appears to be a bespoke design from Brompton’s factory in the UK. So while it works very nicely today, if anything ever were to break on the bike during a long ride, bar one or two M3 cap bolts , there is almost no chance of finding a spare unless you find yourself outside a Brompton Service Center.

It is a nice little minimalist bike. The 5pm ride home from the workshop was a bit rude from sun and hills, but a few stand-ups on the grades had me home in reasonable time.

I stumbled on an interesting story in the Economist today, The lowdown on teardowns: Ripping apart smart-phones reveals their true cost

GADGET-LOVERS the world over are already salivating at the thought of getting their hands on Apple’s much-hyped tablet computer, which is expected to be revealed on January 27th. Most of them just like the idea of playing with a new high-tech toy. But a few have darker designs. They cannot wait to rip the device apart, analyse its design, identify its parts and calculate how much it costs to make.

These “teardowns”, as they are called, are common practice in the electronics industry, and are usually performed in-house. Now, however, more of this activity is being outsourced to specialised firms such as iSuppli and UBM TechInsights. Their findings provide a glimpse into the inner workings not just of individual devices but also the fast-growing consumer-electronics business itself.

I guess this makes perfect sense, in fact, I bought an expensive messenger bag in Tokyo from Fredrick Packer in order to see how they did their fine embroidery. So it makes sense that this is widely practiced in the manufacturing world.

These firms apparently go into excruciating detail in figuring out not only how the product was built.

My dad sent me a bunch of home videos he made.

I’m trying to figure out if my parents are trying to send me a secret message. Like maybe they’re being held hostage or something.

Why?

Because as far as I can see, unless someone went temporarily insane, I cannot explain why the basement is covered in some hideous bright purple paint, even including extension cords! So I was thinking maybe it was a secret distress signal or something. Is “purple” the international color for “Pan! Pan! Pan!” ?

Pan! Pan! Pan!

Just uploaded the power telemetry from my afternoon bike ride. It was the exact same ride I did last sunday. I felt more tired today. That I had a hangover and was riding in 4pm sun didn’t help. Anyway, 68kilometers in 2:30. My device says I did 1396 kilohoules (kJ) of work today and 1365 kJ last week. That number doesn’t mean much too me — what is the significance of having burnt and extra 31kJ today.

It’s either 0.83 x metabolic energy of one gram of fat or 1.8 x the metabolic energy of one gram of sugar or protein.

That is, today’s ride burnt an extra half-packet of sugar. Fantastic.

On my long bike rides, I need to eat, otherwise I deteriorate after about three hours’ riding. I can carry stuff in my back pockets, but it tends to be out-of-sight and kept out-of-mind (I don’t enjoy eating in the saddle). So last night I designed a prototype mussett bag that hangs across my top tube. Its dimensions keep it out of the way of my cables, my knees, and water bottles. It’s big enough to hold some food and sundries.   

I made it out of my favorite canvas duck fabric that I used to make my first messenger bag (which turns out to be a really nice bag that i still sometimes use). I love this durable, low-tech fabric. It’s just tough cotton, so you can make it foul, it politely dries itself out, and you can always wash it later. I embroidered a pig on the side, for color, but I was not thinking clearly and ended up putting it on upside down. I haven’t sewn on eyes or nose. I did add two large snaps to lock down the bag so that it doesn’t slide anywhere.

I didn’t finish it by this morning’s ride because last night I went into a fugue. I convinced myself something was seriously mal-adjusted with my sewing machine. I believed the bobbin spinning part was out of adjustment, thus colliding with the needle. As I was fading to sleep last night it dawned on me I probably had the needle installed 180d incorrectly. This side has a notch that lets the bobbin finger spin by very closely and snag the top thread.

Sure enough, that was the answer.

Then I went into another brain-cramp where I spent twenty minutes fussing with the presser foot and feed dog to make them pull the fabric better before I realized that the problem was simply a dial adjustment had been left at 0 forward advance after I’d working on the embroidery. duh.

Anyway, the bag is ready for my next ride.

Bag installed; simple.

I have been staying on a numbers broadcast IRC chat group and asked what this was. Fast, easy answer, a Russian “one letter beacon,” in my case originating in Vladivostok.

Just had a 14 mhz QSO with v73rs Rob in the Kwajalein Atoll of the Marsall Islands. Had to check Google Maps to figure out where that was. Sort of halfway between here and Hawaii. Lucky I heard him before everyone else, because my signal was quite weak (44) and now everyone else is piling in 59.

v73rs from Kwajalein Atoll

Rob said he was an engineer. Curious, I googled the atoll, and found it’s part of the Ronald Reagan Ballistic Missile Defense Test Site, so whatever he’s working on must be interesting.

My propagation software (DX Toolbox OSX) indicates this contact probably took four hops.

I’m not quite sure what was going on here.  yb3vk/n, an Indonesian callsign, was saying

CQ CQ IN A CW NET DE YB3VK/N CS PSE K

I presume /n indicated “net”, but what does “CS Please” mean in this context? I am presuming it’s not an LOLcat joke.

Think it’s finished, after more than a few hours of tinkering. Lateral deflection is around 0.2mm. Axial deflection, 0.3-0.4mm. The dishing is correct to a mm or two. I got all the spokes tensioned to within +/-10% of the mean. At 107kgf, I’ve got the tension on the drive side rear wheel towards the high side of the Mavic specs (according the Barnett Bicycle Guide), but I think my first wheel failure was from under-tension, so I’d rather err on this side.

Now I have no excuse not to ride a lot this weekend.

Earlier this week I posted about the danger of hypothermia.

Now I’ve found something else: surviving on fetid water.
