Tools & Electronics

Building tools, designing circuits, sharing solutions

I'm Ethan, a senior electrical engineering student who builds tools to solve problems and creates electronics projects worth sharing. Currently the tools are pretty limited, but more will be added soon as I find I need certain things.

About

As a senior electrical engineering student working at an aerospace company, I constantly run into repetitive tasks and missing circuit functionality. I build software tools to automate workflows and design hardware for specific applications.

Everything starts as a solution to my own needs, then gets refined and shared. This site hosts the tools I've built and showcases the electronics projects I've designed.

Hardware Projects

I design and build electronics when I need functionality that doesn't exist or costs too much commercially. Each project includes technical details, design files, and lessons learned.

ESP32 Home Assistant Distance Sensor

In Progress

Wireless distance sensor for Home Assistant using ESP32 and TOF sensor. Features built-in battery, WiFi connectivity, and real-time distance reporting for automation and monitoring applications.

ESP32-C3 VL53L0X TOF LiPo Battery Home Assistant

Power Electronics

DC-DC converters, battery management systems, USB-C power delivery controllers, and efficient power solutions

Interface Boards

Sensor breakouts, protocol converters, development tools, and custom interface solutions

IoT Devices

Connected sensors, home automation controllers, wireless modules, and smart device integrations

My Approach

I build tools when I find myself doing the same task repeatedly. For hardware, I design circuits when I need functionality that doesn't exist or costs too much commercially.

Both software and hardware are built primarily for my own needs, then refined for broader use. This means they address real use cases but may not cover every edge case.
