Hi There! ♡~♪

What I learned from modelling and controlling a rotary inverted pendulum using transfer functions, root-locus PID design, nonlinear Simulink simulation, and a cascaded PID-PD controller.

What I learned while building an eight-channel embedded data acquisition system: component selection, sensor integration, firmware scheduling, UART protocols, and hardware-software integration.

What I learned while implementing an 8-point multiplierless Approximate DFT on FPGA, from MATLAB and HDL Coder verification to pipelining, fixed-point refinement, FPGA-in-the-loop testing, and standalone Nexys 4 deployment.

Lessons from designing a wireless Remote Controlled Microscope controller with STM32, FreeRTOS, nRF24L01+, finite-state machines, queues, semaphores, Hamming-coded packets, and local diagnostic outputs.

Lessons from implementing Sokoban on an ATmega324A with a 16x8 LED matrix, push buttons, UART terminal control, joystick input, a seven-segment display, and piezo-buzzer feedback.

Lessons from designing a networked chess service in C with asynchronous clients, one server thread per connection, shared game state, human matchmaking, and a single Stockfish process connected through pipes.

Engineering lessons from building tpmania, a real-time STM32 rhythm game with a 16x4 LED matrix, arcade buttons, microSD assets, audio playback, and a cross-platform configuration GUI.
