Projects

I worked under Professor Edward Lee, to create a small portable 21kHz ultrasonic frequency generator. I created it using a microcontroller, a ceramic piezo amplifier, and a ceramic piezo speaker. I worked with Matt Weber, Dung Pham, Hoang Nguyen, and Sid Feygin as well as Kaifei Chen's Bearloc to successfully pick up the hardware emitter signals. More information, including code, can be found on my github here.

I created a series of PCBs to interface the x-OSC with other microcontrollers, grove connectors, and to make a standalone mini piano, using capacitive sensors, buitl into the PCB. Another facet of this project was to use the LPKF PCB mill that is located in UC Berkeley's Invention Lab.
