Selected Projects
Representative hardware and embedded work.
APOLLO — Digital Signal Processor
Embedded DSP / PCBUSB-powered STM32F401 signal-processing board with KiCad hardware and STM32CubeIDE firmware. The analog processing loop samples an input, applies a first-order low-pass filter, drives an external I2C DAC, and streams CSV telemetry over USB CDC.
Includes USB-C hardware, analog conditioning, SPI SRAM sample storage, microSD hardware, Gerber exports, and STM32 HAL firmware sources.
View on GitHub →ESP_RFLINK — Wireless Dev Bridge
RF / ConnectivityUSB-C developer bridge for ESP32-S3 and nRF24L01+ work. It exposes one shared JSON command protocol over USB serial, HTTP, WebSocket, and BLE for RF packet control and live events.
Includes PlatformIO firmware, Python SDK and CLI, desktop workbench, embedded browser dashboard, KiCad hardware source, and manufacturing outputs.
View on GitHub →PCIE_FRA — Frequency Response Analyzer
FPGA / InstrumentationStandalone frequency response analyzer for the Alinx AX7015B Zynq-7015 board. The design generates a DDS stimulus in PL, captures an 8-bit ADC response, and performs synchronous I/Q accumulation in a custom AXI4-Lite FRA core.
Includes a bare-metal UART CLI for calibration and sweeps, with Vivado/Vitis project structure and RTL validation flow.
