4. Updated PERT chart

5. Accomplished recently  Continuing research Basic review: about LEDs, power regulators, useful sensors, useful PoE labs  Pursuing PICs instead of Arduinos Cost, learning experience, size  Emailed Keith

6. Keith told us…  Device precision requirements 50-100 V output accuracy Temp. to.5 degrees, current to 1 mA  He will send us LEDs, DC-DC converters (and MXS)  Looking for system to control relative outputs of LED instead of matching to an exact value? (discuss more on Thursday)
