R/V Rob’s Introduction to Greenland Upon our arrival I was relieved to find Rob securely tucked away in his crate in a container at the heliport in Uummannaq. With a few days of mooring preparation work ahead of us, there was not only time to set him up, but also to run a few preliminary […]

When R/V Rob arrived with its bare-bones option control system things were simple. A HiTec Aurora 9 radio controller talked to a HiTec Optima 9 which controlled, via RC PWM signals, a SSPS-105 rudder servo and two RoboTeq AX1500 motor controllers. That was it, all the ‘processing’ such as reversing one of the motors, since […]

Why an A-frame? To facilitate deploying and recovering the CTD from R/V Rob some sort of crane or slide needed to be fitted to the vessel. It was debated, and finally viewed as a fall-back option, to leave the CTD in the water and tow it from location-to-location. However, the drag from towing an object […]

I am working as a Design Engineer on a project at Oregon State University to design, build, and operate a remotely-operated boat (R.O.B.) to be launched from a research vessel in Greenland. This enterprise is one part of a larger observational study to understand the physical coastal processes that are impacting the Rink Isbrae and […]

“Buoys Rock!” is an interactive map reading exhibit. It asks the visitor to interpret a ocean weather map off the Pacific Northwest coast and select the appropriate buoys (buttons) that are experiencing certain weather phenomenon.

Frontier military outposts required lines of communication to other outposts, supply depots, command centers, and field operations. The telegraph was a revolutionary form of communication in the 1870-80’s for the U.S. Army across the American frontier. Starting in 1875-76, the U.S. Army built the first 25 telegraph stations in Texas. In 1882, the U.S. Army’s […]

Bella is special; she’s not at all like the labs that I grew up with, or many of the other dogs that either of us are used to having in our lives. For one, she doesn’t play fetch. At all. She can’t even be bothered to chase after the ball and then not bring it […]

Over the past couple of months I have been working on creating an exhibit for the Hatfield Marine Science Center Visitor Center in Newport Oregon. The three panels below are part of a larger exhibit aimed at increasing public awareness about harnessing wave energy to create electricity off Oregon’s coast. This is still a work […]

The Reason Sometimes projects align. I am involved in frozen produce (Moonshine Park Fish Company), track the local weather while sailing, and have an interest in monitoring energy usage in the home. All three center around logging data, data, and more data. For all of these projects it is time to figure out a way […]

Over the past year we have endeavored to reduce the amount of paper we use and store. This push for a paperless existence began during the preparation for last summer’s ill-fated sailing trip as a way to have all the records we could possible need/want on-board the boat without requiring a barge for the filing […]
