Image-based resistor detection

Features & Capabilities

Resistor Scanner is a handy Chrome extension designed to simplify the process of identifying resistor values through image recognition. Instead of manually decoding resistor color codes, users can point their phone camera at a resistor to instantly get its resistance value. The tool offers automatic detection that locates the resistor and analyzes its color rings without requiring precise alignment (horizontal placement needed in the free version).

Key features include live detection for real-time resistance reading, manual correction by tapping and holding to adjust misread rings, a manual mode to select ring colors directly, and the ability to detect multiple resistors at once. Additional controls such as brightness and zoom sliders, touch to focus, and the option to load images from the gallery provide flexibility and accuracy. This extension is ideal for electronics enthusiasts, students, and professionals who need a quick and reliable resistor value reader.

User Reviews

The app has a promising idea and can aid colorblind users with resistor value identification, aided by zoom/exposure controls and batch readings. However, reliability is a major drawback: frequent crashes, inconsistent results, and camera/lighting sensitivity (glare, white balance) lead to misread colors. Calibration and stability improvements are needed for practical use across devices and environments.

Pros

Helpful identification of resistor values, especially useful for colorblind users.
Zoom and exposure controls help readability and accuracy when lighting is good.
Can read multiple resistors at once and show values for all.
Strong concept and generally useful/relatively accurate in favorable conditions.

Cons

Frequent crashes and instability; sometimes won't run at all.
Highly lighting-dependent; glare, flash glare, and white balance issues degrade results.
Colors detected incorrectly (e.g., brown read as black) and no calibration.
Results vary across devices/backgrounds; inconsistent across scenarios.
Background and lighting requirements make it unreliable in typical conditions.

Recent reviews

This is an amazing idea but sadly it does not display correct values, gave it a few tries on a black non-reflective background, but in it's current form it's really unreliable. 2 stars for the idea and work the author put in. I'd LOVE to see it work as intended. Keep up the good work :)

good app

Overall it seems to work but takes very specific lighting. using an S22+ the flash creates glare that confuses it. a sheet of black EVA foam, construction paper or felt reduces the glare and improves the contrast. link to upgrade and remove ads would not work. Just got it so I don't yet know about long term. 100ohm vs 220ohm detection worked mostly if the light was good and the zoom was larger. The more focused zoom the better so far. that makes sense as it has more pixels to work with
