Project	What it is
Autonomous waiter robot	A self-balancing robot that serves you drinks: LQR control, LiDAR SLAM, A* and DWA navigation, ArUco recalibration and a YOLO emergency stop, on an RPi 5 and ESP32s.
RISC-V CPU	Built a 5-stage RV32I pipeline with a set-associative data cache, forwarding, stalls and flushes, verified with Verilator testbenches.
FPGA-accelerated OneNote	A collaborative whiteboard with hardware gesture and shape recognition. A fixed-point MLP on the FPGA classifying 2.38× faster than software.
Conductor ICHack26	A low-cost, offline NFC system using a Raspberry Pi and OCR/TTS that turns physical spaces into audio-accessible environments for visually impaired people.
Emergency RF comms CGCU Hackathon	A working emergency RF communication system that sends card-encoded signals and reads them back with LDR sensors.
Multi-threaded chat	A UDP chat server in C with POSIX threads, private messages, admin controls, keepalive pings and a min-heap for kicking idle clients.
On Fluid Flow	A model of how viscosity and pressure affect the flow of a Newtonian fluid.
