Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Currently researching components required and conducting analysis of circuit required to control commercial Peltier coolers
Accomplishments from Previous Week
Defined several progress milestones to achieve before attempting to control Dr. Chen's TED as the final product
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish controller code (Justin)
Buy commercial Peltier coolers (Kam)
Further research on inductors and purchase if suitable inductor qualities have been determined (Jeffrey)
Further research on battery options (Tom)
Document procedure for testing which will take place in week 3 (Justin)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Focus on building circuit for one TED and controlling one TED (3/30/20, via zoom)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Suggested we take a look at more efficient battery types and consider what battery voltage we are looking for (4/1/20, via zoom)
Advised that we start figuring out the filter for the circuit to counteract prevent inefficiencies due to the PWM output (4/1/20, via zoom)
Advised we worked on goals in parallel instead of everyone focusing on one goal at a time (4/1/20, via zoom)
Recommended for the team to work with commercial coolers first to test control algorithm
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
None
Risks and Areas of Concern
Although RTDs provide much higher temperature measurement accuracy, they are also very expensive if the final product design will incorporate multiple RTDs in one device
Resources or Information Required but not Available
Flexible TED (not urgent)
Oscilloscope (for later signal analysis)
3D printer (to make battery case)
Schedule
Upcoming milestone: build a circuit and write a control algorithm for an off the shelf Peltier cooler as a working prototype
Budget (list amount spent and amount remaining)
Spent: $156
Remaining: $1844
Progress on Report and Webpage
Template for report draft created; upcoming sections due at the end of Week 2 started
