Fall 2009 Mid-Semester Contributions

I have been working with the Non-Linear Chemical Doser team to design a new non-linear alum doser. The first thing I did was to create a spreadsheet to help with lever length and angle calculations, this helped us determine the necessary lengths for both sides of the lever arm. I also began learning MathCAD using the MathCAD tutorial from the AguaClara wiki. More recently however, I have devoted the vast majority of my time working on the prototype design that is to be presented at the EP3 conference in the spring. The work I have done is primarily on AutoCAD. Monica and I have been through many designs and drawings on AutoCAD, and each design appears to have it's own issues. Working on this prototype has also helped with the rest of the design process since problems that we had not previously foreseen were brought to life during the drawing of our actual doser system. Most of my work can be seen on the Prototype Doser Frame Page. We are currently at the stage where we can begin ordering parts and beginning the actual construction of our device.
