Motor Imagery BCI Classification
64-channel EEG at 250 Hz for left/right hand motor imagery decoding. Three classifiers benchmarked: 1D CNN with channel attention (83.8%), EEGNet (83.4%), CSP+SVM (81.2%). 5-fold stratified CV on BCI Competition 2005 Dataset I.
Respeck Activity Recognition
Chest-worn wearable sensor (12 Hz 3-axis accelerometer). Two-stage hierarchical classifier: Stage-1 coarse (LOCOMOTION/MISC/RUNNING/STATIC), Stage-2 fine within each group (12+ classes). Handcrafted time/frequency features, RF · XGBoost · SVM ensemble. Clinical activity monitoring.
Autonomous Car Vision System
Raspberry Pi 4 + PiCamera2. Three sign-detection backends: template matching (30+ FPS), custom CNN (~15 FPS), YOLOv5-nano (~8 FPS). Lane following via binary threshold + centroid steering. UDP JPEG monitoring stream. ASCII serial motor protocol.
Autonomous Differential-Drive Robot
Built at age ~15 from scratch. Stepper-motor differential drive with empirically calibrated dead-reckoning odometry (CM_PER_PULSE = 0.150325, Rl = 4.79 cm, Rr = 4.78 cm). 8 sensors, 10ร10 occupancy grid, Dijkstra planning, boustrophedon coverage, MPU-9250 IMU, nRF24L01 telemetry.
