Switching over to a ceramic heater requires a revamp of the design
Accomplishments from Previous Week
Switched to the ceramic heater (Watlow Ultramic heater) from peltier junction to simplify design in regards to conduction, cooling, power, and controls
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish most of the ordering parts including the ceramic heater that approved by the sponsor and instructor (Chung)
Determine sufficient amount of power source for the entire device with ceramic heater design (Seonghan)
Learn how to make a GUI for the thermal cycler when plugged into a computer (Leu)
Design a mounting solution for new design (Roh)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
1/28/14 Sponsor meeting
Verified that dwell times for each cycle are 15 seconds at both the peak and valley, but can possibly be reduced
Sponsor OK'ed design change with increased costs.
Lower temperature has tolerance of +/- 5C
Received new ID for ordering parts

Update and complement on the report draft
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
None
Risks and Areas of Concern
Ceramic heater has potential to melt components if the controls catastrophically fail
Resources or Information Required but not Available
Schedule
Build prototype when parts arrive
Budget (list amount spent and amount remaining)
Progress on Report and Webpage
