All Projects
Embedded systems, firmware, IoT and robotics
FeaturedUniversal IR Gree AC Remote
A small ESP32 board that pretends to be a Gree AC remote — control the AC from a browser on the same Wi-Fi.
FeaturedA7670C 4G Module Smart Phone
A handmade "smart phone" prototype around the A7670C 4G module, with a touchscreen dialer, SMS keyboard and inbox.
FeaturedSIM800 GPRS MQTT Test
A SIM800-based test bench that boots the modem, attaches to GPRS, runs an HTTP request and then attempts MQTT — all logged on a TFT screen.
FeaturedESP32 TFT Game Display
A small 2D game running directly on an ESP32 + TFT — no PC, no streaming, just the microcontroller.
FeaturedLinear Encoder 2D Game Controller
A linear encoder turned into a physical controller for a 2D game — sliding the mechanism actually moves the character.
FeaturedSmart Energy Meter Load Controller
A bench prototype that shows live V, I, P and energy on an LCD, takes keypad input, and switches a real load through a relay.
FeaturedAdjustable Bench Power Supply From an Old PC PSU
A recycled ATX power supply converted into a bench supply with an LM317 adjustable output and fixed 12 V rail.
FeaturedAutomatic Power Factor Corrector and Monitor Device
Microcontroller-driven power factor corrector that measures AC load behaviour and switches capacitor banks to bring PF closer to unity.
FeaturedAUST Mars Rover
University Mars rover platform — I led the circuit-simulation and PCB-design side for the team.
FeaturedFlood Relief and Rescue Bot
A remote-controlled bot designed to move through flooded areas and carry small relief payloads.
FeaturedPure Sinewave Inverter with Solar Charging
SPWM-based pure-sinewave inverter with a solar charging stage — built around the thesis idea of hybrid rural power.
FeaturedCircuit Design and Fabrication
A collection of schematic-capture, PCB-layout and fabricated-board work from across my projects.
FeaturedParalyzed Patient Assist Robot
An assistive-robotics concept for paralyzed patients — simple input methods, useful actions, no scary complexity.
FeaturedIoT-Based Home Security
A small Wi-Fi security node that watches a door or a room and pings me when something happens.
Mini Speaker - Super Easy
A compact battery-powered speaker using a PAM8403 amplifier, small speaker driver, charger board, and simple enclosure.
Music Reactive Light
A simple desktop LED strip effect that changes brightness with the bass signal from a 3.5 mm audio line.
Robotics Hand for Industrial Automation
A multi-DOF robotic hand for basic pick-and-place — built to learn actuator coordination, not to replace your fingers.
Puzzle Solving Robot
A small autonomous robot that reads a puzzle/maze environment and follows a planned route.
AC Dimmer Circuit
A phase-cut AC dimmer that smoothly controls a mains lamp using zero-cross detection and an opto-isolated TRIAC.
Automatic Street Light
A small controller that turns lights on at dusk and off at dawn using a light-dependent resistor.
Fire Fighting Robot
A small autonomous robot that detects flame direction, drives toward it and triggers a water pump.
Smart Door Lock
Electronic door-lock prototype using keypad / RFID authentication and a servo or solenoid actuator.
Line Follower Robot
A PID-style line follower built for competition tracks — the one that won 1st at the SAGC 4th Science Festival.
RC Plane
Hand-built remote-controlled aircraft — brushless motor, ESC, servos, and a lot of foam.
3D Design and Printing
CAD + 3D-printing work for enclosures, mounts and mechanical parts that my electronics projects needed.
DIY Portable Bluetooth Speaker
A handmade portable speaker — Bluetooth module, Class-D amp, Li-ion pack, custom enclosure.
Soccer Playing Robot
Wireless-controlled robot for head-to-head robot-soccer matches — fast drive, simple controls, durable chassis.
