Solar Panel Pool Pump Controller

The project

An intelligent IoT pool monitoring system designed to optimize pool maintenance through automated temperature sensing and pump control. Built with an ESP32 microcontroller and DS18B20 temperature sensors, this project monitors both pool water and outdoor ambient temperatures to make intelligent decisions about pump operation. The system features a user-friendly I2C LCD display for local status monitoring and real-time telemetry reporting to a Node.js backend via WebSocket and REST API. The backend, built with the modern Elysia framework, provides robust REST and WebSocket endpoints for data collection and remote control. A responsive SolidJS frontend demo showcases real-time data visualization and connection status.

Shower Pump Controller

An automated water evacuation system for my shower built with Arduino. This DIY project solves a practical problem by automatically managing water drainage using a pump controlled by a relay module. The system employs two float sensors positioned at different heights to detect water levels - one triggers the pump activation when water reaches a certain level, while the second acts as a safety mechanism to prevent overflow. LED indicators provide real-time visual feedback on the system's operational state (standby, pumping, or critical level). The code is optimized for Arduino Nano but can be easily adapted to other Arduino boards. This project demonstrates practical application of embedded systems, sensor integration, and relay control in solving real-world home automation challenges.

22LR

A 3D-printable model of a .22 LR cartridge, roughly 6.9 × 6.9 × 24.4 mm. Per the platform's own disclaimer for firearm-related models, it's a dummy prop with no real functionality as ammunition, intended for display or decorative purposes only.

Arduino Relay Current Safety Box

A two-piece 3D-printed enclosure that fully encases an Arduino relay module to electrically insulate it, reducing the risk of accidental contact with live contacts. The base (37.3 × 50.0 × 7.0 mm) and cover (37.3 × 50.0 × 25.8 mm) print separately and snap together around the relay board.
