Back side of the spoke length calculator. This is a slide rule type tool made of a cardboard sleeve and movable insert. This was distributed through Ron Kitching in the UK. The calculations were based on Howard Sutherland's manual for bicycle mechanics, which spread the data over charts covering several pages.
The "correction factors" presented on the back of this calculator would apply the basic calculations of this tool to any of the more common rims of the late 1970s.
Seeing the now legendary names such as Martano, Nisi, Fiamme and AVA may raise our nostalgia weighted eyebrows, but they were once among the most common marques available.
The "Sprint" rims shown in the 700c listings are for Tubular or Sew-up tires.
I had some fun last night to woodenize my date stamp. Sawed from the wooden beams I dissembled from a cabinet, a wooden cube now replaced the plastic handle from my Cox date stamp, matching the stuffs made of wood on my desk.
I'm still unsatisfied with the new wooden handle, will probably find some way to customize it further. If you ask me what color I like most, I will tell you "wood". Not brown, not dark brown, not burnt umber, just WOOD.
What else I have in wood on my desktop? A calculator with wooden rim, Tivoli Audio radio, antique wooden treasure box to store my travel tools/books, stamps, spools, cutter in wooden box, wine bottle holder, wooden photo frame and mirror, etc. If my dream house can't be in wood, at least my study room will definitely be.
Tonight I'm gonna play with some ideas about a notebook system which has all my favorite elements in note taking and journaling with photos. The polaroid here was taken today with my wife standing in front of a wall holding my Lomo LCA+ with wide angle lens, I should ask her to pose more for stuffs I love, including herself :)

Canada Science and Technology Museum
This artifact, currently on display in our artifact spotlight area, has been linked to our recently acquired Babbage replica. The Italian scholar, Roberto Guatelli, made both of them. Guatelli was a well known maker of historic mathematical reproductions and did several replicas for IBM in the 1960s and 70s. He was especially well known for his Leonardo da Vinci recreations. See The Rotarian, December 1952.
THE ABOVE MODEL IS A REPRODUCTION OF A MECHANICAL CALCULATOR, FIRST DESIGNED BY BLAISE PASCAL IN THE 17TH C. IT WAS COMPLETED IN 1642. THE PRIMARY CONCEPTION WHICH THIS MACHINE INTRODUCED WAS THE MECHANIZATION OF THE CARRY. IT ADDS & SUBSTRACTS DIRECTLY, BUT MULTIPLICATION & DIVISION ARE ACCOMPLISHED BY REPEATED ADDITIONS & SUBTRACTIONS.

linear equation calculator Example ProblemsStep 1  Observe the value of a,b and c from the equation Step 2 :  Apply the formulax = (c - b)/a Solve for x: The equation is 2x + 3 = 5 Step 1 :  Here, a = 2, b = 3, c = 5 Step 2 :  x = (c - b)/a = (5 - 3)/ = 2/ = 1 Answer :  x = 1 Solve for x: The equation is 3x + 6 = 9 Step 1 :  Here, a = 3, b = 6, c = 9 Step 2 :  x = (c - b)/a = (9 - 6)/3 = 3/3 = 1 Answer :  x = 1

Got this cheapass nerdy watch today at K-Mart. I think had this same watch in high school! Except maybe it was about twice as thick. Here's a quick video review of the watch: www.rikomatic.com/blog/2008/07/my-30-second-re.html
