When I’m not out adventuring, I am engineering projects for Square One. I help design and test positioning systems for cryo vac or “space” conditions.

Our project is building a ‘robot’ that can move a sample from point “a” to point “b” not only at room temperature, but also in extreme cryo conditions, -333 degrees without oxygen. The complicated part is that materials change with temperature. Material properties such as brittleness and size change; each material of the robot changes size at  different rates. Figuring out the tolerances so the system can run smoothly at both room and ‘space’ temperatures is the hard part. Only a thousandths of an inch is the difference between a working system and one that fails with the bushings clamping onto rails.


We went to Tennessee to test our positioning system in one of the Space Institute’s chambers. It was great to see our work actually performing in the intended environment!

Bolt Bin!

Mostly, I design robotics components at work, but sometimes you need to roll up your sleeves and fix the thing that is bothering you. For me that was the lack of organization in our bolts and hardware. Therefore, I built a rolling bolt bin and organized the contents. If anyone messes it up now, they will have to settle with me!

Graduation Reflections

I cannot thank everyone enough for helping me graduate college last spring. Dartmouth taught me a lot and gave me the chance to make more great friends than I ever imagined. I am very grateful!



My parents threw a party for me, and it was great to introduce my grandma to my friends and mentors.

Mike Wooten, Head of Student Life and an Awesome Cook
My parents’ friends Wendy and Donnie
Mike and Kathy from the Outing Club. They have Helped me build trails and keep everything moving in the right direction!
Dudley, one of my mentors in the woodshop and a great friend
Bob Dean, My first engineering employer
DVC, my advisor at school, who has helped me get out of more than one tight spot
Peter Speigel, without whom I would not have turned half the bowls that I have
Len and Blossom, forever my best buddies
Hannah and Abby, all we need is Tim and Andrew and we have the original freshman troublemakers

Investiture was a great time to bond with my fellow 15’s, and my parents even agreed to my final college deal – I would behave all week if they let me skip the full campus graduation. Instead of sitting in the boiling heat and waiting to walk across a narrow stage, I went canoeing with my family on a beautiful day in New Hampshire.

I think we made the right choice.

Diwheel Race 2015


It is a Dartmouth engineering tradition. The advanced machine engineering class spends the last 3 weeks of their spring term building diwheels. You may ask what is a diwheel is. As you can see below, a diwheel is a silly looking human powered vehicle. Your pedal power moves small wheels that through friction move big hoop wheels around you. In case you were also wondering, when I say build, I actually mean design, build (weld, machine), and troubleshoot everything except the hoops.


Once the 50 or so students in groups of 4 focus entirely on building this contraption and nothing else (sleep, what sleep), they have a chance to demonstrate their team’s design’s abilities. This year this included turning radius, speed, tracking, and stability.


Turning was a complicated affair, and when mechanisms failed, some teams got creative. Did I mention there were team uniforms?
