If you could have used a screen capture tool, and maybe uploaded in a better resolution it would have been possible to find all the red-red-brown or red-red-black-black through holes.

But what about the SMD resistors. Are we going to assume all the black 1206s and 0805s are resistors?

I occasionally teach electronics, that's probably one of a very few jobs where remembering some of the color codes are still relevant.

TIL the stripes on resistors aren't just colorful fun. I found this tool, but I need to read a more to understand it: https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code

it's really just that the first two tell you numbers, the third multiplies it, and the fourth tells you how much leeway either side of that number you have.

They are manufactured in such a way that a set of resistors can cover everything from 1x to 10x in the range of electrical power you are working with.

[–] Hugin@lemmy.world 2 points 6 days ago (1 children)

The range is set up so that [standard value] + 10% just meets [ next standard value] -10%. They make a batch targeting 1k and test them to sort by tolerance. If they are off by more than 10% they just become 1.2k 10% or 820 10%.

It's the mathematical term for the range in a log scale. 1-10, 10-100, 100-1000, ...

Photo is so blurry I can barely distinguish the colours of the bands on the resistors. And I can't remember what they mean anyway.

[–] Treczoks@lemmy.world 11 points 6 days ago

I did not even care to learn the color codes, as I cannot distinguish them anyway. I always use a multimeter before using a resistor.

Color code for 220 is red,red,brown,blue. The picture sucks, but it doesn't look like any of them match that color code.

[–] Hugin@lemmy.world 13 points 6 days ago (1 children)

Red red brown is 220 next color is tolerance. Blue would be .25%.

Ah, shit, what's that initialism/mnemonic again?

I am so glad that once we're out of school, no one in their right mind would ever not have a guide nearby with all the information you could ever want for your job.

Black brown red orange yellow green blue violet gray white. Bad booze rots our young guts but vodka goes well. Or a more objectional version Bad boys rape our young girls but violet gives willingly.

It's just black-brown-ROY G BV-grey-white

Same with the "select all images with bicycles", theres usually at least 2 or 3 in there that are so blurry you can't tell if it's a motorbike or a bicycle
