PCB & Hardware
Small circuits and control boards from the bench — quick, practical builds rather than full write-ups.
FM Transmitter
Captures audio with a microphone and transmits it wirelessly over FM. Built for the Communication System Fundamentals course project.
MOSFET Switch
Used to control a high-power pump wired to a weight-scale system — lets a small control signal safely switch a heavy load.
Arduino Nano Servo / Robot Arm Driver
Drives a robotic arm using a variable resistor, making it easy to test manual positioning and servo response.
ESP32 12V Control Board
Controls an old RGB LED strip after its original controller was lost — Wi-Fi lets me set colors and effects directly.
Weight Scale (Auto Water Dispenser)
A load-sensing water dispenser that pours precise volumes on demand. Full write-up, test data, video, and code live in the Smart Water Dispenser project.
