3. CS-EE 481 3Founder’s Day University of Portland School of Engineering Introduction -Project is interdisciplinary -Troy- EE/Jon- ME/Arturo- CS -Planning since the start of last summer -Mitch Dec and Dana Troy -Dr. Lu, Dr. Doughty and Dr. O’Halloran -Professor Nuxoll

4. CS-EE 481 4Founder’s Day University of Portland School of Engineering Background -Solar collector -Very efficient way to heat water -Radiant heating system -Run hot water through piping under a floor -Microcontroller (embedded system) -Small computer with limited memory - The aim of our project was to develop and integrate the above into a proof of concept residential heating system.
