Violet is still a whore.

Well, she does go willingly so I guess she's okay with that.

I supposed, but she should treat herself better. Hard to tell what those bad boys are carrying these days.

Is this still taught? Been years since I had it all memorized, but I figured younger generations would be using their phones or apps to figure it out nowadays.

Also even though I was taught this, we had no use for it as we would simply replace entire boards rather than troubleshoot too deeply unless there was a reoccurring error.

It's all SMD nowadays, even the DIY boards.

Still useful for when dealing with systems with industrial wire harnesses. Not all, but lots of them use the color code. Really nice to know which wire you are looking at on a 50 wire harness, thanks to the color code.

And the resistors are also good for breadboarding. But they've been pretty well deprecated.

Ho boy the hours I’ve spent wrapping cables and connectors in e-tape to The Code, ha. Brn-Wht 1-9. “Secondary” with white stripe, tertiary with green/ yellow “zucchini” tape, quadrinary color with all three. Christ I hated redundant systems with 60+ BNC cabling

Clever system! I like it very much but I'm curious, why not just put the Ohms right on the resistor? i.e. if it's 2200, just put 2200.

Because then it would be usable by 100% of the population. This way you can make it useless for 10% of them or so.

Back in the olden days it was easier to paint on the lines.

They do print on the numbers for some modern surface mount resistors. They use a 3 number system because there isn't much room. The first 2 numbers are..... well.... the first 2 numbers of the resistor's value. The 3rd number is the amount of zeros you need to put after those numbers.

So a resistor that is 2200 ohms, would have "222" written on it. Twenty-two with 2 zeroes.

The style of resistor that this color code was intended for can be oriented in any direction when put onto a circuit board. If the writing were only on one part of the component, the resistor could be soldered in place where the resistance value is not visible which would prevent easy identification of the value. Surface mount resistors do have a numeric code on them, but being small rectangles, they need to be oriented with the code facing away from the board. These surface mount resistors are often machine placed so the pick and place machine makes sure they are oriented correctly. Extremely small surface mount resistors do not have room for any code so they are not labeled or colored. It's a bit of a mess really.
