Emulating The Doppler-Shift For Lora Based Low Earth Orbit Satellite Communication, Ariel Freiman, John Stephen Gharib
Electrical Engineering
This project investigates the adverse effects of the Doppler Shift on a LoRa waveform transmitted from a Low Earth Orbit Satellite or LEOSAT. This work is on behalf of Project OWL, who will use these results to justify further investment into developing a LEOSAT for their communication network. Part of the project is to design a test setup to replicate the Doppler Shift in the lab. The Doppler shift replication setup distorts the transmitted waveform, similar to how the signal gets distorted if sent from a LEOSAT. The test setup will comprise both software and hardware control, wherein software, the …

Williams Honors College, Honors Research Projects
The goal of the project is to build a wireless kick pedal that allows accessibility to drummers that have leg or foot disabilities and add versatility to multi-instrumentalists looking to add percussion while playing another instrument. The proposed pedal is designed in two main parts, a wearable band that tracks the player’s movement, and a hammer mechanism that receives actuation commands from the wearable band to move the hammer and deliver a drumbeat. The band is designed to be worn on several parts of the body, including the ankle, knee, thigh, or even the arm depending on the user’s situation. …
