About

Resistor Brain

This app uses your device's camera and a neural network to identify resistors and decode their resistance values from color bands. It offers a unique perspective on electronic components and includes an "Inside Brain" feature to visualize the neural network's processing.

Highlights
  • Resistor detection via camera
  • Color stripe decoding
  • Neural network processing
  • 3- and 4-stripe resistor recognition
  • "Inside Brain" visualization

Join the Resistance - "Resistor Brain" changes the way you look at resistors! #1 Lifestyle app in the alternate universe ruled by electrical engineers! But seriously, the application just detects resistors and decodes their resistance from color stripes using camera and a specially trained neural network. In case the detection is not always accurate you also get some special effects to convince you it is a cool app after all. Have fun :-) Detection accuracy depends on the lighting conditions and the background environment. Flashlight is better than low light but diffused light is usually better than flashlight. Currently the application is trained to recognize 3- and 4-stripe resistors. "Inside Brain" does not do anything productive but is included as a curiosity. Here you can see how the input information changes while traveling through various processing stages in the neural network.

Resistor collar codes calc is a powerful tool for decoding and calculating resistor values using 3-, 4-, 5-, and 6-band color codes. Instantly get the resistance, tolerance, and temperature coefficient (TCR) based on the selected bands. The app also includes a code-to-value calculator, letting you enter a resistance value and see the matching color code. It verifies input against standard E-series values (E6 to E192) and suggests the closest standard resistor where needed. You can also calculate total resistance for series and parallel connections, as well as perform resistive voltage divider calculations — making this app ideal for circuit design and quick calculations. Key Features: • Supports 3-, 4-, 5-, and 6-band color codes • Calculates resistance, tolerance, and TCR • Enter values to find matching color bands • E-series validation and nearest standard suggestion • Series and parallel resistor calculator • Resistive voltage divider calculator The application supports multiple languages, including: English, French, German, Indonesian, Italian, Polish, Portuguese, Russian, Spanish, Turkish, and Ukrainian. Perfect for students, hobbyists, and electronics professionals alike.

Verdict

The call

The clearest difference is in-app purchases: Resistor color codes calc at none against Resistor Brain's 3. Resistor color codes calc also leads on review sentiment (100% vs 67%). Resistor Brain's advantage is ads (none vs shown) and update cadence (daily vs every 2 months). On price and device support there is nothing between them.
