Measuring Angles

Worked on my latest “science project.” I’m trying to move an arm smoothly to any angle using a pneumatic piston. This brings together LEGO Mindstorms and Pneumatics, as well as 3rd-party digital sensors to measure air pressure and angles. This is proving surprisingly challenging.

Moody Mississippi

It warmed up sufficiently to comfortably walk outside. The reflection in the icy Mississippi reminded me of a moody Turner painting.

Loose Goals

The chill continues: walked for about an hour through corridors and stairways in the two towers of our building. My daily workout goal is “move” but I’ve yet to figure out how to explain that to the software.

New Year’s Day Tradition

Our New Year’s Day tradition is a long walk and a bar lunch. With subzero weather all day we achieved one out of two. Maxwell’s is our local, a chilly two-block walk.

New Year’s Paella

Our annual tradition: celebrated the new year in Madrid at 5:00 p.m. Central then made paella.

Public Service Building

Included the Minneapolis Skyway in my walk to escape cold and ice. Finally got to see inside the new Minneapolis Public Service Building. I’ve previously admired the exterior, so it was good to walk through the beautifully designed interior, including this skyway section.
