Electrical engineering student at McMaster University.
I build things with circuits, and I learn by building.
Hi! I'm Viha, an Electrical Engineering student at McMaster University with a passion for technology, innovation, and problem-solving.
Through my co-op experiences at Flowserve and Hammond Power Solutions, I've gained hands-on experience in electrical design, control systems, instrumentation, and engineering simulation. I'm passionate about applying my technical knowledge to real-world challenges and exploring new areas of engineering.
Outside the classroom, you'll find me on a hiking trail or behind a sketchbook :)
A 12-transistor CMOS XOR designed, simulated, and built from discrete PMOS/NMOS. Sized transistor ratios for ideal switching and measured rise/fall time and propagation delay on the scope, with correct logic despite real-world sizing constraints.
view report →Two MOSFET-based switch circuits characterized for ON/OFF resistance, leakage current, and bidirectionality. Measured results matched theory with small deviations in a hands-on study of real-device trade-offs.
view report →A 2N3904 common-collector (emitter-follower) stage designed as a buffer: high input impedance, low output impedance, ~0.9 gain between a 100 Ω source and load. Midband gain, linearity, and low harmonic distortion verified in simulation and on the bench.
view report →A DC supply delivering 10 mA at 3 V ±0.1 V from a 120 V (rms) 1 kHz input, using a center-tapped full-wave rectifier and filter capacitor. Simulated and measured regulation held within tolerance despite diode drops and capacitor tolerances.
view report →A 360° indoor scanning system: a VL53L1X time-of-flight sensor on a stepper motor collects distance data every 11.25°, the microcontroller streams angle–distance pairs over UART, and a Python app renders live 2D/3D point clouds with Open3D.
view code →A line-following robot that detects recyclable materials by sensor and deposits containers into the right bins. Arm motion, hopper interaction, and sorting logic were validated in a Quanser simulation before building the 3D-printed, laser-cut physical prototype.
view code →Two-player Snake in C++ built on custom data structures: dynamic arrays and a linked-list queue drive movement, food spawning, growth, and collision detection, with clean separation of game logic, rendering, and input handling.
view code →Bandgap reference + temperature sensor + ADC mapping −20–100 °C to an 8-bit code, HOT flag at 85 °C, under 1 mW on 1.8 V, in the SKY130 process.
