A DIY digital scale built around a custom steel-beam load cell with strain gauges in a Wheatstone bridge, instrumentation amplification, and a higher-resolution external ADC for stable mass readings over a 0–1000 g range.

A hands-on control-systems project: ESP32-based drone controller with gyroscope feedback, custom motor drive circuits, and a Wi-Fi control interface. Achieved lift but faced stability limits tied to thrust-to-weight constraints, leading to a planned migration to brushless motors and higher-power architecture.

A deployable outdoor IoT controller that plugs between an AC outlet and pond heater(s), enabling manual or automatic temperature control for up to four devices with web configuration and telemetry.

A compact sensor node concept with custom PCB and 3D-printed enclosure, showcased as a Home Assistant multisensor with live data presentation and device visualization.
