I dislike the blue color, but it's been a long while since I don't carry one of my good meters together with alligator clips when I am sorting this type of stuff. My eyesight is going fast as well...

Regarding sorting, I use coin envelopes that allow me to scribble any type of info and fit very well in quite a number of cardboard boxes.  :-+

4. When you are done or have desoldered one throw it in the bin and forget it existed.
5. If you drop one, throw it in the bin and get another one out.
These points are becoming more common with me.  Even when using breadboards, the resistors don't usually find their way back to the fold.

Sounds like a plan ... and one that fits the way things are going with me.  :-+

the benefit of blue resistors or non brown resistors is that natural over heating deformation is brown and char is black, these colors stand out on blue, so a quick visual inspection may detect problems

however, there are better colors for this possibly, White resistors?

if you notice, fuses are often light green (through hole littlefuse), not sure if this is done for this reason to identify burn. The problem with white might be false positives from flux and dust contamination, they will show everything.

I assume you like the really old brown ones (true cylinder shape), not the tan ones, those will stand out better



low level/hunch/probability based analysis usually leads me to believe the tan resistors are 5% carbon film, but this is not always the case.

That poll at the top of the thread is clearly lacking an "I don't care" option.

Don't remember the last time I've seen or used a giant barrel resistor. Just put many 0805 resistors in parallel/series if you need higher power rating.

Don't be absurd.  Carbon composition resistors aren't something anyone really likes these days.

They did have one thing, though, that the blue bodied beasties do not possess .... readable bands.

Is it the first band, or the last?

This, too. The blue ones usually have five bands, arranged symmetrically. It's usually hard to see which end to start decoding.

The brown ones are a lot more obvious.

This picture could be used for EE torture.
I go with light blue Xicon 271 and can't stand the dark blue Yageo MFR-25 brutal hard to read- orange/brown/red look almost the same to me.

The bastard is 33k2 (second from right) but I just realized the problem is LED lighting has very little red spectrum in it. The colours look much better under halogen lighting- although  dark blue body still sucks.

Err bin, bin, hmm bin, bin, bin, bin, bin, bin and bin.

At least it's not like that bloody awful Pearson textbook I saw once where the print was so bad you couldn't tell the difference between brown, red and orange. I was asked to review it for a friend before he gave it to his son and suggested he burned the fucking thing.

What I find much worse are dark green metal film resistors. The darker colours are almost completely unreadable

What are these odd things with leads, anyway? Have we travelled back in time to the 1980s?

Stuff all this modern rubbish, carbon film, metal film, metal oxide, whatever. Lets go back to good old 2" long solid carbon resistors with body, tip and spot colour coding, those were the days!!
DC coupling is the devils work!!

color code is so 1950's.

Those of us getting a bit long in the tooth also don't appreciate the fact that metal film resistor bands are so thin! That certainly doesn't help, in combination with the color contrast issues mentioned above.
But I like quality, precision, and dependability, so I try not to grumble too much. Metal film units have served me well over the years.
Yepper, keep El Senor Ohmmeter handy...  \$\Omega\$\$\Omega\$\$\Omega\$?

BTW, in reply to an earlier post, why would anyone want to identify a roasted resistor, anyway?  :-//

Blind date with a resistor? Hope she's 10k lol
0402 only really used in mobile stuff - cell phones, tablets, laptop etc. where electrons of no particular value travel. I'll bet none of your test gear has 0402's.

0402? Phone? Well, at least we've made it up to 2005 now..

Where's the power? 0402 good for 63mW. I can't work with little pepper flakes, too small for my eyes and the slightest bump sends them flying.
It's weird one consumer product drives the entire electronics industry towards the smallest parts, to the extinction of engineers being able to prototype something. In that sense, blue resistors are awesome.
