PROJECTS
DIGITAL RECEIPT SYSTEM VIA NFC (in progress)
-
Transfers a receipt from a POS terminal to your phone via NFC.
-
Reduces the need for paper receipts at checkout.
-
Implementation uses Raspberry Pi Pico using FreeRTOS and OM5577 (PN7120) NFC controller module (with custom designed interface board)
SERVER-BASED STATE LOGIC ELEVATOR CONTROLLER
Designed and implemented a multi-story elevator controller accessed and controlled via web interface.
User commands are securely sent to server (Raspberry Pi) running MySQL, back-end uses state logic to determine elevator destination.
Real-time elevator monitoring information displayed on UI.
WIFI CONTROLLED ROBOT
Designed and fabricated a micro-controller based embedded system (ARM Cortex-M4 on custom PCB).
Robot is capable of a being controlled via wireless controller and/or automated robotic system.
Implemented fully customizable PID controls.
System includes RS232, CAN bus, SPI and I2C interfacing, TCP/IP socket programming, ADC and DAC, and the operation of motors (stepper, DC, servo), and an LCD display.
EMBEDDED CONTROLLER BOARD
The board's intended purpose is to be used as the heart of the WiFi Controlled Robot project.
It exposes the peripherals of the STM32F303 board, allowing full utilization of hardware peripherals.
CODED MESSAGING SYSTEM
Allows two computers within the same building to communicate without LAN or internet access!
Uses PSK modulation circuitry to communicate via household wiring instead.
AUDIO AMPLIFIER (15W)
Designed an AC-DC converter to power the amplifier from typical 120VAC.
Assembled audio amplifier board and optimized components for best performance.
Crafted the mechanical chassis with external switches and ports.
ROAD TRAFFIC VIBRATION SENSOR
System is capable of detecting ground vibration caused by passing traffic and generate a graphical representation of results.
ANALOG MULTIMETER
Designed analog multimeter which is capable of measuring voltage, current, resistance, and magnetic field intensity.
ROLLING LED DISPLAY
Designed hardware and software for rolling LED that displays text in a left-to-right fashion (like a marquee).
Uses Axman board as main micro-controller.
