Resistor Colour-code Calculator

There's this:
http://myfreewares.weebly.com/resistor-colour-code-solver.html
Seems versatile: colours to value, value to colours and P(ower)-V-I-R.
There's a portable zip on the page - no setting up needed.

I use this web-based one. No program to download:
http://samengstrom.com/nxl/3660/4_band_resistor_color_code_page.en.html
Although most of the resistors that I have are not the value stated,
because they have been removed from aircraft and replaced.

Left to right. (Yes I know, I know).

Quoting "young girls" and "virginity" is not racist :)

I certainly knew them well before age 11 (and before I would have
known what a virgin or a racist was, so it's unlikely any mnemonics
would have helped me), but I do remember "body, tip, spot"!
TBH, one of the things that initially attracted me to electronics at
such a young age was the pretty colours on resistors, and being
curious about why. My father had done lots of electronics before I
was born, and I retrieved his boxes of it from the loft, and started
from there.

Ther capacitors were even nicer - don't see them these says. Looked a bit

Oy! I don't look like a capacitor, although I am becoming a little

Capacitors were all quite boring when I started. Just blue or orange film
around the metal.
But I did love hoarding resistors. I used to nip into Tandy on the way home
from school - buy a pack of resistors, and use my Battery Club card! :-)

Pigs for the end breaking off the swiss-roll though, if you pulled on
the lead when soldering.
What was the name for these? Polyethylene foil and a cement dip AFAIR,
but they had a name too?

Are we talking abiut the same thing? These were rectangular, flattish,
with rounded edges (typically about a cm per side, 2-3mm thick, wires
from two of the bottom corners, horizontal stripes. Polyester ISTR.
Frank Erskine
say:
They were modern things. Proper condensers (mica) were maybe 1" x 3/4"
x 1/16" and dipped in brown wax, or encased in brown bakelite
(engraved with the value) with large flat tags sticking out of the
ends.
Or Hunts/TCC paper ones in an aluminium tube with rubber seals in the
ends.
Then of course there were wet electrolytics that had to be kept
upright...

Mylar - I think those were mylar film. Or possibly ceramics. Mullard
made em IIRC.
http://store.triodestore.com/mullardfishcaps.html
I remember at that time..yes. its coming back. You could get stripey
humbugs that were coil wound plastic, then mylar film, which was better,
and polycarbonate, which was way best of all, because instead of a coil
(flattened) they interleaved the plates.. Very low self inductance AND
they ground the ends down to precision values.
Bob Eager
Yep, seen (and mostly used) all of those too. But not as pretty...

Really ? Never new that. That could explain one or two things ...
Presumably one only ever encountered them hard mounted on (pre-war)
wireless set chassis.

Oh, so that's what the "virginity" was all about. I learned 6-7-8-9 as

We were taught it a little bit different. I'm sure it was 'rape' instead of
'root', and the last four words were 'but virgins go without'.
I don't remember it being 'bad' either. But can't think what it was.

Bad Boys Rape Our Young Girls, But Virgins Go Without.
Throwing sensitivity to the wind, the other version substituted 'Black'
for 'Bad'. I've no doubt there's a perfectly acceptable but dead boring
version out there.

(halfway between black and red) grey for eight and white for nine.
I never had any problems, or need for mnemonics.
After a while the coses were second nature for preferred values in the
E20 range anyway.
Had to think a bit for high precision sometimes.
