1. Thermo-Cooler Controller Kiefer, Mary, Molly, Sam

2. Update Each part (PWM & PID) was tested; code was interfaced this morning ▫Motor set-up works so that pulse width controls the speed of the motor (a pot controls the pulse width) We tested and retrieved data for the TEC inside and outside of vacuum with constant DC power ▫We’re in the process of converting the data to temperature

3. Current Assignments We are meeting after this group meeting to re- organize and delegate the next tasks These tasks will at least include the following: Solidify and build our conditioning circuit Find the PID constants Research frequency control Interface the PIC code with the rest of the system
