Hue Test Fail

May 28th, 2009

These are our results from an online Farnsworth-Munsell 100 hue test that Sylvia found on the Internet. The test involves arranging color swatches into a continuous spectrum of hues. The bars indicate which hues we were unable to arrange correctly and I’m not sure what the height of a bar means.

As you can see, we got very different results depending on the display used for the test. A proper FM100 test kit costs about $700 and has to be completed under controlled (D50) lighting conditions. Nonetheless, it’s fun to play with the pretty colors and create some order from the randomized initial state.

Arthur Ganson

May 9th, 2009

Sylvia and I saw a Ganson exhibit at MIT a few years ago. I just came across his youtube page with some videos of his pieces.

If you can stand the opening crescendo, there is a nice TED talk in which Ganson talks about his work.

How It’s Made is a TV show that I used to watch on the History Channel and a Mystery Hunt puzzle begging to be written. Each episode details the fabrication process of four different things. See if you can figure out how the topics for any given show are connected.

Episode 37

  • Car Radiators
  • Hatchery Chicks
  • Phyllo Dough
  • Cross-country Skis

Episode 66

  • Three Wheeled Vehicles
  • Baseball Bats
  • Artificial Bonsai
  • Trombones

Items requiring more than one segment to describe

  • Buttons
  • Carbon Fibre Cellos
  • Stamps
  • Goalie Masks
  • Optical Lenses
  • Giant Tires
  • Stetson Hats
  • Sugar

You can find lots of segments on YouTube and a complete episode list on Wikipedia.

Stepper motors

February 24th, 2009

I picked up these four Powermax II stepper motors (P21NSXC-LSS-NS-03) on eBay last week. They’re a lot heavier than I thought they would be and huge compared to my previous stepper motor. They have a holding torque of 116 oz-inch, which I learned is the number of ounces you could suspend from a 1 inch rod attached perpendicular to the motor shaft.

Seriously, what am I doing with my life?

February 16th, 2009

For the last 15 months I’ve been a programmer at the Center for History and New Media. It would be hard to find a smarter, more dedicated group of folks building new media projects in academia, however programming just isn’t the career I want. I started working part time this month and by March I’ll be down to around 12 hours a week.

Sylvia has two and half more semesters of law school, at which point we’ll most likely move out of Baltimore to greener pastures. Where, exactly, is an open question, but Berkeley and Boston are on top of the short list at the moment.

My plan for this year is to think about exactly what I want to study and then apply for PhD programs in December. Along the way, I have some goals:

  1. Build a non-trivial robot. I’m working on two very different designs, one is a gantry setup with an arm for manipulating items on a table and the other is a suspended rig that interacts with people from above.
  2. Read more. I spend a lot of time reading news and other articles on the internet, but it’s been a long time since I got all the way through a book. Sylvia and I recently founded a book club (we’re the only members) and started From Molecule to Metaphor: A Neural Theory of Language.
  3. Blog it out more. I would like to write a post a week, which would surpass my previous best of a post every twenty six years.
  4. Publish something. One of my few regrets from my time at Berkeley is not contributing to any peer-reviewed publications. It would be lovely to have at least one peer-reviewed publication on my CV, even if it’s not a full paper. Part of this challenge will be to read broadly across journals and conference proceedings to find out where I can and want to fit in.

This is shaping up to be a real banner year. Check back for updates. I’ll be posting some robot sketches soon.
