Digitally Tuned RF Receiver 📻
Built a digitally tuned FM radio receiver from scratch using an ESP32 and a TEA5767 module. Overcame physical hardware challenges, including resolving I2C communication failures, eliminating ESP32 signal noise by using proper decoupling capacitors and stabilizing the LM386 audio amplifier by implementing a Zobel network.
Arduino Dinosaur Bot 🦖
Built a hardware-based bot using an Arduino Uno and a light sensor to physically play the Chrome Dinosaur game. The system uses real-time sensor input to trigger servo actuation based on calibrated thresholds.
📁 Circuit Technology
Operational Amplifier Circuit Analysis
Designed and simulated an operational amplifier circuit utilizing NI Multisim. Calculated nominal output voltage and evaluated circuit stability by testing input voltage offsets to identify failure thresholds. Executed Monte Carlo analysis on resistor values within a 3kOhm range to determine output voltage minimums, maximums, and statistical distribution.
Diode Harmonic Shaper
Implemented piecewise linear approximation using potentiometers and diode branches to progressively clip and reshape a triangular waveform into a near-sinusoidal output for harmonic shaping analysis.
📁 Microcontrollers
Microcontroller I/O Interfacing and Debugging
Programmed an EasyPIC v7 development board to manage I/O operations, specifically controlling LED arrays and interpreting button states. Configured hardware registers (ANSEL, TRIS, and LAT) to define port functionality on PORTB and PORTC. Developed control logic to trigger specific even/odd LED patterns based on corresponding hardware button inputs.
📁 Materials for Power Electrical Engineering
Investigation of Magnetic Losses
Investigated magnetic (watt) losses in soft magnetic materials by measuring hysteresis loops. Set up and operated physical measurement circuits including a variable transformer, multimeters, and a current converter. Utilized an oscilloscope to capture the primary magnetization curve and calculate specific energy dissipation.
