Follow our journey as Molly, Gwyn, Sam, and Eric work on a low voltage power supply project. Yesterday, we fixed a temperature sensor circuit, soldered a surface mount current sensor, discussed I2C DAC code, and explored Eagle to Express PCB conversion. Today, the plan is to complete testing, finalize parts list, conduct thermal analysis, solder a DAC, work on coding tasks, and design PCBs.

Low Voltage Power Supply Molly, Gwyn, Sam, and Eric
What We Did Yesterday • Fixed temperature sensor circuit- it works! • Successfully soldered a surface mount current sensor and tested it on a breadboard • Gwyn talked to Brad about I2C DAC code • Eagle to Express PCB conversion research
For Today • Finish testing converters and sensors, start solidifying list of new (final) parts to buy • Decide what thermal analysis should be- we can use the temperature sensor to monitor a converter in a vacuum for the duration of flight • Try to solder a DAC using the new boards • Keep working on coding tasks • Convert Eagle schematic to a format that works with ExpressPCB and start designing PCB
