Hi it's me again! 0_o
Do any of you have a hard time reading the color bands on resistors?
Well I am! When looking at the resistor itself:
1) I cannot see yellow bands against the beige resistor body at ALL.
This is less of a problem, as if i see no band, i can usually assume
it's yellow. White bands are very very faint.
2) Red and Orange. If one is right next to the other, sometimes i can
tell them apart, sometimes not. If there is only one or the other on a
resistor, i never can tell which it is.
3) Black, brown and violet. If black or violet is next to brown, i can
tell it's brown. If black or violet are next to each other, they both
look black. Brown by itself sometimes looks black, or occasionally
looks like red, depending on what is next to it.
What's funny, is that i'm not colorblind at all- anywhere else i don't
have this problem. In fact, i just recently saw an eye doctor and they
did the usual battery of "what number do you see in the dots" tests.
No problem. I was also fitted with glasses that correct my
astigmatism- everything is in focus now. I fiddled with electronics
somewhat about 10 years ago, and don't remember this issue.
I have one of those lil "resistor color code cheaters" from radio
shack's days of yore- turn the wheel and dial up the right colors, and
it'll show you the numbers. I don't have as much of a problem seeing
those colors, with the exception of black and violet (i distinguish
those by the numbers they bring up!).
All in all, when in doubt the DVOM comes out. I usually try to read
them first, and then measure them to see if i'm right. Sometimes i am,
sometimes i'm not.
I was suspecting my lighting- I haven't opened it up to look, but my
overhead light is probably a 100W incandescent. I took some resistors
of known values into the closet to view them under the flourescent
light. I expected the problem to be worse, but it's slightly better.
Not enough to help, but slightly better. I haven't tried sunlight yet-
it's been raining, snowing or cloudy for the last few weeks.
I might try a GE Reveal(tm) bulb:

Claimed to filter out "dulling yellows" and improve color clarity.
Dunno if it will help or hurt.
Anyone else have this issue, found a solution, or am i just not trying
hard enough?
Thanks for letting be dribble...
