|This UFO is actually a demonstration of a "Three Vee" Kinematic Clamp.|
The three spherical UFO legs, combined with the three slots in the base provide
exactly six contacts points, and no degrees of freedom. This yields a repeatable
joint to within 2-3 micro inches, great for re-assembly.
|"The Stick" is a cell-phone concept initiated by Dan Chapman. |
Using the jig shown below, I took his original 2-D concept sketch,
and produced a 3-D surface model in Alias StudioTools.
|This is a course I took Spring semester of 2001. |
These files represent the geometry I created while taking the class.
All files were produced in SolidWorks 2000, except the dragon,
which was modeled in Alias StudioTools.
|The goal of this project was to create an injection mold to produce |
a large number of topological legos we call "triconnectors." This concept was
developed by Prof. Carlo Sequin. My contribution was the design of the snap features,
part sizing and shaping, mold design, and manufacture of the mold and subsequent parts.
These graphics show the project progress from concept, to prototype, to CAD model,
to mold, to finished parts.
|I decided to make some custom guitar picks for the lab and myself. |
The "BMI" picks are souvenirs for visitors to the lab.
The "DanO" picks are so I'll never have to buy picks again.
The triangle symbol is one I've used since I was a kid,
and is somewhat similar to the ying-yang symbol.
I based the design on my previous favorite pick: the Jim Dunlop Nylon 1mm.
The mold halves are reversible, so any combination of graphics is possible.
Aluminum was used to make the molds, and the picks are molded form Delrin.
I'm happy to report that they play very nicely.
