What is resist.?

resist. helps you identify resistor values instantly using a photo, live camera capture, or manual band selection.

How it started and how it evolved

resist. started as a simple tool to avoid checking resistor charts manually. The early version focused on basic image input and direct resistance output.

As the project grew, it evolved into a full workflow with smarter detection and better usability. It now uses YOLOv8n + ONNX for offline-first local inference, supports 3/4/5/6-band resistor logic, auto-corrects reversed band orientation, and includes an optional Gemini fallback.

Some features -

• AI photo detection with local ONNX models.
• Live camera capture and analyze flow.
• Manual band picker with live resistor preview.
• Correct formula handling for 3/4/5/6-band resistors.
• Offline usage after setup, with optional Gemini override.
