Video: Tom’s friend Robert’s Kinetic Sculpture

This is a kinetic sculpture build by Tom’s very talented friend Robert Swarner. Robert came into Tom’s shop in Santa Cruz in the early 90′s wanting to learn about sewing so he could build his own climbing equipment. They’ve been friends ever since. For a brief period of time Robert sewed for Tom, but they found drinking margaritas together was more fun. For fun, Robert has been an artist, a machinist, a sky diver and a big-wall climber in Yosemite, and for a living flies helicopters.

If you can prove to Robert you understand what this thing does, we’ll send you a Friend of Tom pouch. Submit your summary in 45 words or less to: darcy@tombihn.com

“This is a mobile. The rotating part is on a nut that spins down that screw
under gravity. The computer watches its position on the screw and when it
gets to the bottom, it turns on the motor, spinning the screw to return the
nut back to the top, ad infinitum.

I wanted to know if I could propel the nut that way using only its momentum
to push against. Usually if you’re moving a nut by turning a screw, you
restrain the nut against rotation. Here I’m just turning against momentum.
I also wanted to see the sinusoid motion of a rotor reacting to wind, and
the reaction of a Delta 3 hinge in a system that is slow enough to watch.

The system is unstable without the rotor bit, and the aerodynamic drag that
goes with it. When I ran it without the rotor attached, the nut accelerated
down the screw, the motor came on, and further accelerated the rotation of
the nut, and something bad would have happened if I hadn’t turned it off.
Because of aerodynamic drag, the nut decelerates to its terminal speed while
it’s descending. Even though it accelerates while the motor is turning, it
reaches a stability in its RPM during the descent. This made me really
happy we don’t live in a vacuum. Aside from being short of breath, it would
be terrifying to move things around without drag.

The hinge that I mentioned is common in tail rotor designs. The problem
with rotor systems moving on edge like a Frisbee is that the airfoil sees a
headwind half of the time, and a tailwind the other half. This is why a
Frisbee always rolls to the retreating side.

The Delta 3 hinge allows the blade to flap as this is happening, only in
this case the flapping axis is 45 degrees from the axis of the rotor. If
the airfoil flaps away from the centered position, the blade is forced to
pitch back toward that centerline, and it is self-stabilizing. You can see
the rotor reacting to gusts of wind, and sailing up and down. The hinge
helps to stabilize it back into a flat orbit.

The airfoil is a cut section of an Agusta helicopter main rotor blade.
Everything but the lead screw, the nut, and the blade section was
manufactured by me.”

Orders over $20: Complimentary Fourth of July Small Organizer Pouch

Orders over $20: Complimentary Fourth of July Small Organizer Pouch

We came up with a limited edition Organizer Pouch to celebrate the Fourth of July: the Fourth of July Small Organizer Pouch. It’s made out of our new Navy U.S. 1050d ballistic nylon and features contrasting red trim and white stitching on the zipper. And we added a “Made in USA” label just to remind everyone where all TOM BIHN bags are made. Place an over $20 order now through Tuesday, July 5th at 12:30pm Pacific Time, put “Fourth of July” in the comments box during checkout, and we’ll include a complimentary Fourth of July Small Organizer Pouch in your order. This applies to pre-orders or backorders too: we’ll include the Fourth of July Pouch in your order whenever your order ships.

Ballistic nylon was originally developed to be used 20 or more layers thick to make bullet-proof jackets. One layer thick, it makes great travel bags; however, it is not bullet-proof or even fireworks-proof. The good news is that it is pretty quiet and won’t scare kids or cats or dogs.

(Remember that the colors red, white and blue are also the national colors of Chile, Costa Rica, Croatia, Cuba, the Czech Republic, France, Iceland, Liberia, Malta, the Netherlands, Norway, Panama, Paraguay, the Philippines, Russia, Serbia, Slovakia, Thailand, Taiwan, and the United Kingdom. So even if you don’t live in the U.S., you might still like this pouch.)

The Travelite® FAQ on our new Cardinal 1050d ballistic nylon

“The cardinal red color was introduced today on Bihn’s blog. While Bihn fans may already be familiar with his previous crimson ballistic nylon, his blog entry includes a photo comparing the two reds side by side, and it’s obvious that the new cardinal red is a much deeper hue. If you’re looking for a travel bag that’s not your ordinary neutral tone, but you shy away from the really bright colors, you’ll want to take a look at the cardinal. It’s a big pop of color, but it’s deep and rich. If you’re looking for a bag with standout color, the cardinal red is an instant classic.”

Design Features Explained: Aeronaut Grab Handles

The grab handles at either end of the Aeronaut were designed to be in the right place at the right time. Specifically, they provide an inviting and obvious place to grab and give the Aeronaut a yank to extract it from an overhead compartment of a plane or other tight spot. They’re reinforced, so if you need to pull hard, go ahead, and because they’re padded, the whole process will be as comfortable for your hands as possible.

The Setup: What does Mark Jardine use to get stuff done?

The Setup: What does Mark Jardine use to get stuff done?

The Setup is a collection of nerdy interviews, asking people from all walks of life about the software and hardware they use. Mark Jardine, known for his work at Tapbots, responds: “When I’m on the go, I choose between my second generation iPad or my 11” Macbook Air depending on the type of work I plan to get done. It’s a good thing they both fit into my tiny Tom Bihn Ristretto bag (though not at the same time). I also never forget my Shure SE530 earbuds to drown out the outside world.”
