[Alex Busman]’s first foray in iOS programming looks like a pretty useful tool. He came up with Ohm Sense, an iPhone app that will take a picture of a resistor and calculate the value based on the ...

The values or ratings of electronic components are indicated by the electronic color code that was developed in the early 1920s. It is not only seen in resistors, but also in capacitors, inductors, ...

Some people look at a venerable resource like resistor color code charts and see something tried and true, but to [Andrew Jeddeloh], there’s room for improvement. A search for a more intuitive way is ...

Today is the 2 nd of February in the year 2022, and red is the color used to encode two. Unfortunately, today’s five-band scheme uses a different color for the five band that indicates the tolerance ...

Here's the plan: I want to use one bi-color resistor for Power and HDD activity on my briefcase box. I want it to be, say, green when just the power is on, and flicker red when there's HDD activity.

I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more careful than I…). Then one day, he asked me ...
