Bouldering Peuil with vero, lolo and thomas

thinking of our friends in Toronto and hoping things are getting better

anodizing

I anodized the Al housing for the new light this week.  For some reason I found it difficult to find any concrete numbers on the various parameters involved, so here is what I learned:

try to use constant current instead of constant voltage (i.e. do not connect to a car battery).  When I monitored the current starting at the generally recommended 12V, it was in the 6 amp range for my part and rapidly trailed off.  Since the process that is occurring is the creation of an Al2O3 layer which is etched by the sulfuric acid (which creates pores into which dye can diffuse), the balance between acid strength and current is critical.  My part had ~ 160 dm^2 and I was shooting for 2 amps in ~10% Sulfuric acid.  Therefore, a massive peak current of 6A which trails to nothing probably does not deposi a very even layer of anodization.  The other thing I discovered is that it is best to use a new Al electrode every time, and make sure it is connected very well to your part.  I had two test runs where the current dropped to 0, and I assumed it was because the oxide layer was so thick that there was no more conductance.  I now think that it was simply the reused Al wire getting oxidized to the point where it could not contact the part any longer.  I cleaned the wire in NaOH every time, but that is probably not enough.

Notable things seen on the AM commute: an Electricte de France Unimog, probably off to do some repairs in the mountains, a recumbent bike with a fluorescent windsock, a traffic light on a freeway offramp about to cause a major pileup.

Limestone bouldering!




deluxe baby accommodations:


and bouldering potential for the height challenged:





It's a beautiful time of year to be up there. The whole forest is covered in a thick carpet of brown alder (?) leaves, and you can see the giant cliffs that flank the Vercors in the background.

Meuliere

We made a second attempt to hike up the 'facile' loop trail that takes you past the ancient millwheel quarries above le Mont Saint Martin (last time darkness and baby crankiness overtook us). It's amazing to see the remains of ancient facilities where they hand shaped millwheels and then moved the 1 ton wheels down the mountain... in the 14th century!

There are amazing looking cliffs to the NE, none of which appear to be equipped


beautiful light as we got back to the car



and a sleepy Zoe

ice cream in winter

Grenoble has two (maybe more?) amazing ice cream makers: the place near the Jardin de Ville and Gonzalez. I have previously posted about some of the weird flavors that Gonzalez makes such as tomato, mustard and basil. Anyway, the boulangerie across the street just happens to sell tubs of Gonzalez ice cream. So far, I've tried the caramel with beurre salé and fleur de orangier (orange blossum). Both have been excellent and I am saving up my euro centimes for a ice cream cake!

mom gone :( !

lunch in town

followed by visiting the Grenoble museum, which is excellent. I should really try to take ZZN there more often. And by more often, I mean 'ever'. Somehow I only seem to visit museums these days when the parents visit!

tour de sens, Chambery

My mom and I went to the Tour de Sens (on the way to les Sept Laux), where we had a fantastic meal:

Some kind of carrot foamy thing on a layer of caviar. Like a fruit on the bottom yogurt, but with caviar, and no yogurt.... I couldnt really understand what was being said.

Trompette de mort mushroom (love that name) mousse with butternut squash soup

puff pastry with chorizo and shrimp

some kind of delicious fish (mullet?), cooked perfectly

MEAT and the best french fries ever. I have no idea how they cooked them, but they were perfect. I suspect duck fat was used. The pasta were perfectly cooked too, of course.


Tiramisu on a pear crumble


yogurt lemon emulsion with candied citrus at the bottom.


We could barely move after the lunch

but pressed on to visit Chambery. I had never been to the old town, and it is wonderful!



Then back home via the Chartreuse (D1006) and St. Laurent du Pont. All of this was on Franck's recommendation. Thanks, Franck!

a short hike through the Chartreuse:

wonderful fondue

Franck and Silvia generously invited the whole family (including the Screaming One). Dinner was a fabulous fondue and amazing handmade chocolate cake. I need to figure out how to get chloe to make those cakes. Perhaps a recipe subtly planted in her wallet, or a web page left open?

biking

For grenoble riders, I found PDF maps of the bike lanes AND a very handy test of bike locks

Internet + free international calls -- FINALLY! (almost 10x faster than the normal DSL package in the bay area, too)!

yikes!

Almost crashed this morning on the bike: lots of wet leaves+slight downgrade = getting sideways on the bike!

le Mont Saint Martin

When I first started college, I joined the cycling team. I had never road biked before, but had done a lot of mountain biking and didn't think it would be that different. I turned out to be pretty far off the mark on that one. My style of mountain biking was anything but sustained. I would go all out for a few minutes then find a suitable descent and repeat for a few hours. The result was zero endurance, and a pretty serious spanking when I first started the endurance hungry sport of road racing. To be honest, I never was much good at it, and didn't even manage to finish many races because I was constantly getting dropped. I also seemed to crash frequently because of my lack of skill with toe clips. For all the failure and road rash though, I loved the daily team rides through the fall colors of New England, and the speed and teamwork of a mini peleton (when I wasn't crashing into rear wheels).

I started cycling in earnest again this spring after a long lapse, and am loving it: hills, flatland, rollers -- I love it all, even on low output days when it feels like my wheels are flat and melting into the asphalt. Yesterday I took the small road up to le Mont Saint Martin directly out of le Fontanil because I had heard so much about it. The word that I heard the most in association with the climb was 'steep', and it did not disappoint. There are *really* steep sections, and for all of my newfound love of biking, I found myself cursing my lack of power. Even in the cold air, sweat was pouring down my face and stinging my eyes, my heart rate was pegged and my legs were feeling like Jello. "Just how F@#$ing steep IS this?", I thought to myself. After twelve or so switchbacks, I actually asked a couple walking their dog whether it was far to the top. The man cocked his head in a look of pity and seemed to be forming a 'Oui' with his mouth, but then thought better of it, shook his head, said "Non.", and followed it with an "Allez!". Despite the pain, it was a beautiful ride -- full fall colors, chestnuts on the ground and blue water streaked limestone cliffs. The descent was a tad fast for my taste though.

sweet!

Here are beam shots of my cheapo light (Cree Xlamp CRE R(?) bin, 350 mA micropuck) vs a $50 cateye EL520.




Mine is the second. Exposure parameters are the same: 1 second, f2.8, ISO 80

Monastery

A trip to the monastery with the fam. Stephanie and Chloe and Alex had to go ahead because Zoe started obsessing over sticks and pebbles.
