Roll Over America – starting day in Portland

The Roll Over America Velomobile tour began at Salmon Street Springs on the waterfront recently and I had a P.90 to test before shipping it off to Lithuania. So I made a trip over the Morrison bridge to check out the cool collection of human powered three-wheeled vehicles. They are beautifully designed engineering marvels and were arrayed facing the waterfront in front of the fountain.

It was a very bright Portland day and a good crowd had gathered to see the travelers off on their cross-country adventure. Since their departure was emminent, I went to work photographing the riders(?) and their vehicles. There was a real exitement in the air about these Velomobiles that had been shipped from Europe specifically for this event.

Since it was uncharacteristically bright for a Portland day, I enjoyed working at a fairly rapid pace with relatively short pinhole exposures. There were a number of variations on what seemed to be the typical Velomobile design so I sought out a few unusual examples for the photograph above. These are cyclists of course, and they were outfitted accordingly.

I thought about how enjoyable it would be to travel with the group and document their exploits. But I had to settle for serving as an illustration of a "typical" Portland inhabitant with my African Grey parrot Zane on my shoulder and a rather unusual camera on a tripod while another Portland resident explained to the Velocyclist below why Portland was such a great city. The young rider was from the North of England (I unfortunately neglected to get his name!).

Semper Vivus – Porsche made the first hybrid?

Porsche hybrid lives again!

It's a cool looking car with those big electric motors on the front wheels . . . "Always Alive" in the translation of its name. Built in 1900 by Ferdinand Porsche, the car utilizes a small petrol engine to generate power the the electric motor driven front wheels. There's a Porsche video here.

I'm a fan from childhood since my father worked for Porsche and raced the on the SCCA circuit. But there is something slightly incongruous about the maker of fast sports cars having this vehicle in the family line. My dream job would be to have been involved in the reproduction process. There is a lot of information about the Semper Vivus and even a driving impression online since the unveiling eariler this year.

Technology in the arts

It was known to all of my friends where I was raised at the outskirts of San Antonio, Texas.

That whine . . . six horizontally opposed cylinders ("boxer" the Germans call it) moving back and forth at exceedingly high rates of acceleration. Intake, compression, ignition, exhaust over and over again all in the service of motivating a sculpture on four wheels to move in a single direction at high velocity.

A friend's older brother drove the American dream machine - a Dodge Super Bee. A classic V-8 sound emanating from a car whose running gear hadn't changed much in 20 or more years. The other kids thought it was pretty cool.

And of course there was the occasional sound of a passing vintage British sports car or the week-day ritual of our neighbor - "Clark Kent" I thought to myself - who came home from work in a Corvette wearing his nice business suit only to emerge from his garage a half-hour later on his Harley Sportster wearing his Banditos vest and tattered blue jeans. In those days the Harley sound was unmistakeable. "Thumpa-da-thumpa-da . . ."

But to a kid accustomed to the game of identifying military aircraft flying overhead by the sound they made there was no sound quite so sweet as that made by a brand new 1967 Porsche 911S  ("driven as it as meant to be" as my father would say) as it screamed past our flag football game returning my father home from work. The circle of friends in the sports car world he inhabited while working for Porsche Cars Southwest helped introduced me to the idea that art and engineering were next of kin.

So it was natural for me to find fascination in the world of automatons. There were countless examples in the odd museums and wacky collections we visited. Whirring gears, creaking mechanisms - crude but mesmerizing attempts to mimic the natural movements of living creatures. That fascination for the connection between technology and art, mechanics and aesthetics - heck, even science and silliness has informed my interests ever since.

So when I first stumbled upon the interesting story of the pile of brass gears, cams and assorted mechanical body parts "dumped on the steps" of the Franklin Institute in 1928 and only recently appreciated for what they were I had to know more. So now the Institute has put together a more detailed account of the adventure on their website.

"Draughtsman-Writer" by Henri Maillardet

"Draughtsman-Writer" by Henri Maillardet

The Draughtsman-Writer belongs to the golden age of automatons when technology was at stage where the talented individual could master an extraordinary level of facility with it's disparate bits and pieces. DR's given talent is writing and drawing. And perhaps the most intriguing part was the discovery that it can identify it own maker. The text it writes in an arc at the bottom of the work below reads "Ecrit par L'Automate de Maillardet" or "Written by the Automaton of Maillardet."

There are videos (1) and (2) on the website that show the amazing facility of this creation. In one of the videos the Draughtsman-Writer creates the rendering of a sailing ship below.

Winding Watches

My design for a multiple watch winder

Many objects made by human hands throughout history speak to the need to accomplish something extraordinary. Often such objects simply arise from a single-minded dedication and a fair bit of skill. In other instances, such an unusual object could only result from the meeting of maker and benefactor.

no 106 Breguet

One intriguing example of the latter is the Breguet watch no 106 designed for Marie Antoinette. It is a tour-de-force of 18th century horological technology commissioned in 1783 (with no time frame and an unlimited budget) as a gift by an anonymous admirer. It wasn't completed until 1827 - after Marie had been sent to the guillotine and Breguet had passed away. I'll refrain from commenting on the political, economic and societal circumstances surrounding the creation of this watch but its recent history serves as a bookend for a story that's a sure candidate for a compelling film plot. The master thief Na’aman Diller, a perfect heist, an unsolved case and a one-of-a-kind watch made for a queen.

With its rock crystal faces - it was clearly intended to fully display both the effort that went into its making and the wonder of its 23 "complications". But more germane to this story is the fact that Marie Antoinette was the first customer for Breguet's self-winding watch design called the perpétuelle.

The self-winding mechanism of a mechanical watch is dependent upon the movement of the watch wearer to spin an out-of-balance flywheel configured as a pendulum whose back and forth movement is utilized to keep the watch wound. This in turn is predicated upon the owner actually wearing the watch . . .
And, in the case of a watch such the No 106 Breguet, this is vitally important since the halting of the watch mechanism means not just manually winding the watch but resetting (without a keyboard) each of its various complications as well.

So picture yourself a collector of contemporary and vintage mechanical watches. (Check out the Breguet site for an example of the current state of affairs). You own a collection of watches - many with multiple complications and maybe even a few with the legendary tourbillon mechanism. To insure they are all ready to wear without tedious adjustment of the mechanism they must be kept wound. Sure, you could spend your mornings going through the collection manually winding each watch in turn (or maybe strap them all to your arms, don a full black cape and go for a nice long stroll.) But as it happens, the easiest way to keep them all ticking is to arrange a means of simply rotating them on the mechanical axis for a given number of turns per day and all is well.

Maybe something like this . . . Strap the watches onto the rotating and spinning arms and set the whole thing in motion.

The common solution is more like this:

Oribita Avanti 12 watch winder

A nice cabinet with individual winder mechanisms for each watch. Simple, efficient and to-the-point.

But take another look at the Breguet no 106 above. The watch is a miniature mechanical circus act in a glass case. There were much simpler watches even in Marie Antoinette's day (she reputedly carried a simple Breguet watch to the guillotine.) Such a watch served the time keeping function quite satisfactorily. It's clear from a review of the current offerings that the typical watch winder of the present day is a philosopical sibling of the simpler Breguet.

So I wonder why such mechanical poetry as is displayed in the no 106 might not also find its way into a watch winder. Clearly most perpetuelle owners would be inclined to have their watch collection handled by a winder like the Orbita Avanti. But surely someone would enjoy having the watch-tending chore managed by a more engaging mechanical contrivance such as the design that begins this posting.

As it turns out, I was commissioned to pursue this very idea.

More next time . . .

Timely motion

winder

Sometimes the oddest things come along.
Fascination with the dance of elaborate mechanism designed to subvert modern technology inspired this design.
Perched at the edge of the notion "Automaton", this contrivance, to be made from brass aided by precision stainless steel bearings, will be suspended within an elaborate case designed to preserve its function and protect its precious cargo. A poetic means to an arcane task.
More than that I cannot say . . .
