Analysis of Activities based
on a Single-Shoe Equipped with Force Sensors

I created a pressure sensing smart-shoe out of velostat material and an embedded system. I then collected data of movements from different physical activities before using this data to train a decision tree model for real time activity detection. [View Repository]

Consumer Facing Smart Shoe Controlled by Embedded System

For my undergraduate senior design project I created a smart shoe with integrated sensors and actuators (accelerometer,weight sensors, ultrasonic sensor, vibration motor.) as well as inductive charging capabilities.
My role on the team was the design architech. I designed the hardware system and sensor layout, whcih involved designing the circuits and positioning of the components. As well as the software system layout, which involved organizing the system drivers and scripts. [View Repository]

Two Player reaction game programmed
onto FPGA in VHDL with VGA output

Using VHDL and the Basys-3 Artix 7 FPGA I created a game where two players race to hit the switch corresponding to a random light lit up on the board. The current winner is displayed out through VGA signal as either red or blue. [View Repository]

Python Based Point of Sale System

Used Python to write an application that serves as a text based POS system that organizes data and creates an order log for the user.[GUI in progress] [View Repository]
