Couple days ago, the above arrived, forgot to hit "post reply" (I often do. Or is it don't?)
One of the things I love about PedalPCB is the way everything arrives soundly packaged, and with a package slip (some places don't give you one).
With the slip you can quickly confirm your order.
This past labour-day sale I ordered...
1 Grover Drive
1 Cattle Driver
1 Celsius Pre
1 Champ Stamp OD
1 Flock Harmonising Fuzz
1 Permanent Breadcrumb
Excellent, all accounted for and...
Oh my! How delightful...
1 BuggFX Raincoat, to boot!
That last one, I asked for it after I'd already placed my order, and the gracious generous Power-That-Is, the force behind PPCB made it happen.
I hope you talking about a PCB, you can get them at the Chemist!View attachment 32295

Hey I too want a PedalPCB resistor chart with my next order!
Like I'm ever gonna learn how to read those. I don't even know which side the tolerance band is!
As long as they're printing something they might as well print the value and be done with it, methinks but nope...arcane colored bands...

Colour-coding's not so bad, it doesn't take long, just a little effort.
Everything is repetitive anyway. For example:
If you see a yellow band (4) followed by a purple (7) you know it's 47-something. Next step depends on the modifiers...
You know it could be 47 Ohms 4k7 47k 470k 4M7 47M... depending on what the 4th colourband is. The 5th colourband just tells what tolerance it's made to — all of mine are brown for the last stripe, meaning +/-1% tolerance, brown being the colour for 1.
GREEN BLUE? 56-something etc
I still don't know my identifiers (4th stripe) as well as I should (involves math), and sometimes the colours are a little off (is that stripe red or brown?).
If I have a Brown Red Black Brown Brown (1k2) maybe it's a Brown Brown Black Red Brown (11k), so I still measure with a DMM as I build, but knowing the colour-system still speeds up the process, especially while breadboarding and you wind up with a loose handful of different values after trying to set a bias point.
I encourage trying to learn it because I avoided it for so long and then once you make the jump you realise it wasn't so bad and you want to go again. Oh, wait, that was bunji-jumping...

Yes the system makes sense but I also become colorblind and can never tell red from brown, violet from gray etc.
Of course they have to make resistors blue and mustard to mess with us even more.
No, my solution is so much more elegant and efficient:
- quintuple test values with 2 different DMMs and a TC1 (that's 15 checks)
- quadruple check the PCB and the docs
- triple read the values out loud in Italian, English and Polish (that's 9 numbers)
- double check the brown tolerance band is on the right when inserting the resistors in the PCB
- insert the resistor leads through the pads, unevenly every single time

DMM it is then.
Yellow = 1, brown = 2... then what's red again?
Yellow = 1, brown = 2... then what's red again?

Doesn't help us folks with red-green color blindness.......DMM for me!

I don't have an issue distinguishing colours except for certain companies who have managed to source the brownest red known to man or green that manages to look yellow in different lights.

I really wish that brown wasn't used as the tolerance band since it's quite easy to read them backward.

I’ve always thought that the tolerance band should be differentiated from the others in some way

Speaking of resistors.... Any of y'all know of (1/2w film; 1/4w carmon comp sized) black resistors? Ik some carbon comps are black, but those seem hard to track down and especially expensive ($2-3 per, instead of typical canon comp prices). Only others I've found are 10w, so of course way too large. IK, mojo & aesthetics bullcrap, its stupid, blah blah... I just want pretty looking black resistors for board I'll be building with exposed internals. don't want to have to break out the spray paint

Technically the tolerance band is supposed to be spaced further away from all of the others, and it seems like either it, or the first digit is supposed to be wider than the others. I never can remember...
Brown / Red, and Red / Orange can be nearly impossible to differentiate between sometimes.
I need to get some more. I might still have one or two laying around.
I want to have a few made up with the EIA-96 SMD number codes. Color codes are one thing, but you're an animal if you can remember these:
