I'm an engineering undergraduate at UC Berkeley. Check out what I've been doing in college!


  • Debugging was done on the oscilloscope to ensure proper amplification of the voltages

Video Demonstration


For my Instrumentation in Biomedicine class, my team and I worked on EOG (electrooculography) technology. Essentially, electrodes attached to someone’s temples send a voltage difference (based on the corneo-retinal dipole) to a circuit designed to filter and amplify the signal. The signal is fed to an ADC (analog-to-digital converter – in this case, the ADC of an Arduino Uno) and used to change the colors of a neopixel jewel.
