The mission of the Symposium of University Research and Creative Expression (SOURCE) is to provide a university-wide forum for Central Washington University (CWU) students, encouraging equity, diversity, and inclusivity, representing all disciplines and experience levels, to present their mentored research, scholarship, and creative works in a juried environment that meets professional conference standards and expectations.
The 2022 SOURCE program is hybrid. Pre-recorded virtual talks are colored green and can be watched anytime. Live/in-person sessions with Zoom access can be found in the daily schedule. Thank you for joining us!

This project provides an energy efficient way to power a motor. The motor is controlled by the microcontroller and powered by batteries which is being charged by the solar panel. As solar power is fed into a battery charge controller, the battery charge controller will charge the battery until it is full. In a process called power pathing, if the power from the solar panel is larger than the power from battery, then the motor will receive its power directly from the solar panel. Otherwise, the motor will be powered by the battery. On the topic of batteries, battery protection must be in place to make sure that over-charge or over-discharge does not occur. Placing a couple of battery protection IC’s (integrated circuits) will ensure that neither of these things will happen. A thermistor will be implemented in this system to provide accurate temperature measurements of the ambient air. This temperature measurement will be used to control the speed of the motor by sending the data into a microcontroller. The microcontroller will drive the motor to run faster the hotter the air around the thermistor is. The output of this instrumentation system will be monitored by a microcontroller and displayed on the microcontrollers LCD screen.
