No spyware. It only asks for access to the camera. I run CM 11 anyway

Re: Resistor Scanner For Android

Does the body color matter (metal film, carbon composite, etc.) ? Can it figure out a resistor versus an inductor?

Does it figure out tolerances correctly? How about three significant digit resistors?

Does it figure out burned up resistors? This may be the most useful app if it can do it. The others is just more spyware/adware...

"Can it figure out a resistor versus an inductor?" unless you tell it what you are testing, same for the color band for the caps.
Inductor color bands.

"Does it figure out burned up resistors?" No way.
The lights quality will also come into play since some time it is hard to the true color of the bands.
Just learn the color codes.

Well, it was hoping that it could detect the body color and automatically tell if it was a resistor or inductor since they look so similar And hoping that it'd have some intelligence to detect burned resistors, who knows what can be done with image recognition...

What do you expect for the generation that can't add or subtract without a calculator. They need a spell and speak to scan cans and tell them it's full of peas...

Well, even a well experienced person has troubled with burned colors. If the AI in the script can estimate the color shift based on discoloration of the body of the resistor and how it can translate to the individual bands... it could be more accurate than a human reading it.

Also the fact that since metal film resistors are blue, inductors can be green or tan (and potentially shaped slightly different), it could make a decent guess at which ones are inductors. It technically could also have a good guess if a resistor is a flame proof or not.

Don't know, I'd never use such program except perhaps for burned resistors. The color shift is hard to tell without some color processing which is better left for a computer. I've seen enough resistors and even with a lookup table that has long since been memorized, takes longer than just recalling the resistor value rote ...

Rote does not work for inductors for me yet, sadly. Have to still use memorized LUT and figure out the multiplier. Have not processed enough inductors...

My phone was struggling to focus on the resistor, it might be better with newer phones with better hardware.

I'm a dichromat (red and green) and so are 5% of males. I have a hard time telling red and brown snooker balls apart, but traffic lights are no problem. Blue and purple are also difficult to distinguish, probably due to the red content. I invariably need to measure resistance values or ask a colour-sighted person to identify them for me. However, these "sighted" people often have a hard time, too.

If I wasn't such a rusted on Luddite, I might one day trade up from my silly phone and take advantage of this tool.
