Team Vision for Preliminary Detailed Design Phase

During this phase, the team solidified a design for the physical chamber as well as beginning development of the control program in LabVIEW. The chamber was changed slightly, the 4 peltier cells used to heat the water reservoir were moved to a single location and the water reservoir was modified to accommodate this change. Additionally, the bottom plate thickness was decreased from 0.5" to 0.25" and a 0.5" flange for clamping was added around the perimeter. These structural modifications were made in accordance with information gathered from the machine shop.

Development of LabVIEW software has begun. LabVIEW uses front/back panel design: front panel is user interface (UI) and back panel is actual code (block diagram format).
