DIY Welding Positioner Controller using ESP32-P4 and Touchscreen UI
Posted: Wed Apr 01, 2026 2:01 am
Hi everyone,
I would like to share my DIY welding positioner controller project.
It is based on an ESP32-P4 with a touchscreen interface and a custom LVGL UI designed for TIG welding workflows. The goal is to build a reliable and user-friendly controller for welding rotators and positioners.
Main features:
- Touchscreen control interface
- Smooth rotation control
- Adjustable speed
- Designed for DIY welding positioners
- Modern LVGL-based UI
- Open-source firmware
The project is still under development, and I am continuously improving both the hardware and software.

Feedback, ideas, and suggestions are very welcome.
