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

2. Update We ran into problems with our conditioning circuit yesterday ▫The input impedance of the oscilloscope was dominating ▫The small resistor was burning up ▫Solution: Seek help from Brian Storey Pushes back our vacuum test a couple days ▫Solution: Put random noise into model and start solving for PID constants Had problems getting four-wire configuration to work ▫Solution: Built the thermistor circuit so that we have A way to measure temperature

3. Current Assignments Wait for responses from Vanderlei/Dominik and Brian Storey Verifying the PIC code Testing the PWM on PIC Created a testing setup with motor and “flag” Building the conditioning circuit Weigh other options Experiment with other ideas Continue working on the RTD circuit (less important than it was before yesterday)
