firmware.ino
A collection of hardware and software projects spanning embedded systems, IoT devices, and intelligent applications. From environmental monitoring stations and navigation systems to AI-powered chatbots and web dashboards, each project represents hands-on engineering work across the full technology stack.
Zephyr Station
Aug 2025 - Nov 2025
ESP32 smart-room monitor combining temperature, humidity, pressure, and air-quality sensors with an OLED readout, RTC-timestamped SD-card logs, and threshold alerts.
Blind Stick
Jul 2018 - Aug 2018
Smart mobility aid with obstacle detection and voice alerts.
Jolt Locator
Nov 2025 - Dec 2025
ESP32 GPS-and-compass prototype that displays coordinates and heading on an OLED and guides users toward a configured Jolt store location; the project also includes its first KiCad PCB design.
Servo Light Switch
Jan 2026 - Jan 2026
ESP8266 receives serial commands from an HC-06 Bluetooth link and moves two servos to toggle wall switches, returning each arm to its center position after a command.
RFID Attendance System
Jan 2026 - Feb 2026
Two-board attendance logger: an Arduino Nano reads RFID cards and RTC timestamps, while an ESP32 manages registration and duplicate checks, OLED/LED/buzzer feedback, and CSV records on an SD card.
Electromagnet Controller
Jan 2026 - Feb 2026
Arduino Uno and CNC Shield V3 firmware pulses two stepper motors together to wind an electromagnet coil, with pulse timing controlling the winding speed.
Inductance Meter
Jan 2026 - Jan 2026
ESP8266 meter samples an RL circuit step response, estimates its time constant and total resistance, then calculates coil inductance and displays the readings on an SSD1306 OLED.
Marcus Omega
Jul 2025 - Sep 2025
A philosophical AI companion with 23 conversation modes, a 10-turn context window, and exportable chats kept only in the browser session.
VS Code Portfolio
Jul 2025 - Present (Regular Maintenance)
Portfolio website styled as VS Code editor.
Shape Detection System
Feb 2026 - Feb 2026
Six Python image-analysis exercises using OpenCV: contour-based geometric shape classification plus image analyses for cookies, cones, trees, and smartwatch displays using thresholding, color segmentation, and circle detection.
Android Studio Apps Collection
Year 1 - College Event Project
Year 1 college event project containing two Android Studio apps: EncoderDecoderApp and a Twitter-style social app.
Energy Consumption Pattern Analysis
Year 2 - AI/ML Mini Project
Python research pipeline for shape-first segmentation of synthetic household load profiles: engineers 51 scale-invariant behavior features, applies PCA and stability-informed K-means, and includes validation, explainability, and interactive dashboards.
RoleForge
Sep 2026 - Present
TypeScript career-preparation CLI and skill that analyzes repositories for sourced candidate evidence, matches that evidence to job requirements, and prepares tailored resumes and CVs with validation and human review.
Unicode Clean
Oct 2026 - Present
Dependency-free Python text sanitizer, browser app, and Codex skill for conservative Unicode and whitespace cleanup. It preserves common Markdown code and URL spans, records its changes, and flags meaning-sensitive edits for human review.
