built an active anti-roll system for a 1/10 off-road rc car, with the goal of reducing rollover on uneven terrain rather than just making a standard suspension upgrade. i designed the linkage and printed parts, wired an arduino nano with an mpu6050 imu, and wrote the pid in c/c++ to turn orientation data into servo-driven ride-height adjustment. most of the work was in getting the whole loop to behave in the real world: packaging the electronics cleanly on the chassis, powering it from the rc receiver, and tuning the pid response through repeated testing on slopes, rocks, and rough surfaces.

afda was a fixed-wing drone project aimed at early wildfire detection in catalonia. my part was mainly the electronics and physical build: integrating the speedybee flight controller, power system, gps, receiver, and raspberry pi payload, then helping turn that into an airframe that could actually survive and fly. the project was useful because it forced real trade-offs between structure, weight, manufacturability, and onboard electronics instead of treating them as separate problems.

designed and validated a piezoelectric accelerometer for subwoofer testing. i focused mainly on the electronics and software side: signal conditioning via an integrator circuit, arduino-based readout, and calibration/testing support for the final prototype. what made it interesting was that it sat in the middle between theory and hardware, so we had to connect the mechanical model, the analogue circuit behaviour, and the measured shaker-test results instead of solving each part in isolation.
