Projects
A few projects and case studies.
Sound Control for Birds
A production‑ready, single html web app to control an ESP32 over MQTT via WebSockets (ws/wss). It publishes exact JSON commands (POWER, WINDOW, START/STOP, PLAY1/PLAY2, DELAY, VOLUME, STATUS) and streams live status/telemetry with a dark, responsive UI. Includes Mosquitto/EMQX presets, auth, MQTT 3.1.1/5, a timestamped console with mute/compact/auto‑scroll, and localStorage persistence—no build tools required.
EQUINES
Phase I delivered the Flutter + Firebase dashboard and ESP32 sensor nodes for feed, water, activity, and ID via BLE beacons. Phase II (in progress) adds vital‑signs: Stage 1 Heart Rate, Stage 2 Body Temperature, Stage 3 Respiration Rate, and Stage 4 streaming/alerts for these metrics.

About
I’m Bharat Raj Dhaka, an Embedded & VLSI enthusiast and STEM educator. I build fast, reliable systems where hardware meets software.
At Govt. Engineering College Bikaner, I actively work with two labs: the Innovation Centre & Product Design Lab and the VLSI & AI Lab.
Innovation Centre & Product Design Lab
- Rapid prototyping with CAD, 3D printing/laser cutting, and in‑house PCB design/fabrication (KiCad, CNC) for idea‑to‑prototype cycles.
- End‑to‑end product sprints: design thinking, MCU/sensor integration, firmware, testing, and iteration.
VLSI & AI Lab
- Digital design in Verilog/VHDL, simulation/verification (ModelSim/Quartus/Vivado), basic FPGA bring‑up, and testbenches.
- Intro to ASIC flow (RTL → synthesis → timing checks) and fundamentals of STA; robust design under constraints.
