A dual-axis (Yaw & Pitch) photovoltaic tracking system equipped with high-side INA219 I2C current/voltage telemetry, DHT22 climate sensors, and closed-loop battery charging.
Dual-axis solar tracking mechanical frame
This system dynamically tracks the sun's trajectory across two degrees of freedom using a cross-axis quadrant of 4 LDR photoresistors and MG996R high-torque metal-gear servos. Integrated INA219 high-side instrumentation logs open-circuit voltage, load current, and instantaneous power, while a DHT22 logs ambient temperature and humidity.
Preventing micro-controller brownouts under heavy inductive servo loads required dedicated high-current rails and common signal reference grounding.
Demonstrated measurable photovoltaic power harvest gains over static panels while providing real-time telemetry logging.

IoT & Embedded SystemsA modular ESP32-powered home automation controller supporting multi-channel relay switching, MQTT telemetry, local web dashboard, and physical wall switch overrides.
Why we built this
Modern home automation proprietary hubs are expensive; we engineered a low-cost, open-hardware controller with fallback physical wall switches.

Bionic RoboticsA 5-finger bio-inspired articulated robotic hand driven by tendon cable lines and micro servos for dexterous grasping and tactile sensor experimentation.
Why we built this
Commercial prosthetic research hands cost thousands of dollars; we created a fully 3D-printable bionic hand so students can explore prosthetic control and bio-mechanics.
