  • Red background with white contrast lettering
  • Adhesive-backed
  • Highly portable
  • Lightweight
  • Reliable
  • Negligible error rate
  • Extremely low power consumption

    Will you be releasing a breakout board for this?

    • Yes, but it's proven VERY difficult to reflow. We don't have a full datasheet for the sticker, but it seems that it doesn't tolerate our usual reflow map. We will have to use a much lower temperature solder paste. These might be slugs even as none of them respond to code.

        If they turn out to be useless will you be selling them at reduced price? Worst comes to worst they wouldn't make bad stickers...

        • N.Poole / about 13 years ago / 3

          who, big negative rates on that, I guess people are serious about their stickers here...
          ...I used to think I was so good at sarcasm...

  • SomeGuy123 / about 14 years ago / 4

    I just noticed that the resistor in the picture on this sticker has 4 leads?

    • Madbodger / about 13 years ago / 2

      It's so you can use Kelvin connections to accurately measure the resistor to check your work! :)

    • Yeah, who made that mistake? I want to know so I can buy one, write all over it poking fun at the fact that it has 4 leads!!1!ONE!1!! and stick it on his window.

      lol, maybe it's some kinda weird SIL resistor...
      Anyway, I'm buildin' my order for next week and this is definitely goin' on the "pile," I've got a cigar box full of stray resistors I collected working at "The Shack" and it'd be nice to slap this on the inside lid.
      ...I'm eyein' one of those sweet lab coats for my next order too... hmmm...

  • Since you already have the design made up for the back of your resistor kit. Why don't you make the back of the resistor kit a sticker? Or make a sticker that looks like the back of the resistor kit. I would buy one of these if the colors matched their word representations. Make it look just like this... ... then I will buy five of em!

    To be honest, my iPod Touch has 3 programs that does the color code for me, but I keep forgetting to keep it charged. This will be handy on the back side of the iPod... Or maybe a notebook...
    I think I need to buy a handful so if I forget where I stick them, I can put a new one up.

    I like the sparkfun red idea. But you need to see the curious inventor business card.

  • ahdavidson / about 14 years ago / 2

    Of course, I see that.
    But my point is that if you have to stop to read the name of the color, rather than just see the color, it will take that much longer and be that much less useful.
    I would much rather pay a little more for something lots more useful.
    In fact, for a buck, I can print out something in color on sticky labels and use that.
    Gee, maybe I wil!

    • N.Poole / about 13 years ago / 2

      And... And what if the resistor has 5 or 6 bands!? How am I supposed to find out the tolerance... or the temperature coefficient!?!?
      ...That is unless this was just supposed to be a fun and cool sticker to add to my collection of geeky workbench trinkets and not a hardened reference material like those found in your average engineering textbook...
      ...couldn't be, though.

      • If you are buying resistors with that high tolerance and temperature ratings, I don't think this chart is for you. Also, it's $1, and no one is forcing you to buy it.

    • For sure! There are many charts and calculators out there. This is one of my favorites:
      This sticker is just a quick reference.

  • ahdavidson / about 14 years ago / 2

    A resistor identification tool that isn't in color?

  • Fezder / about 10 years ago / 1

    ''Extremely low power consumption'' haha, laughed a lot. But, after all, we live in ''green'' earth nowadays...

  • Member #42616 / about 13 years ago / 1

    You do realize that a viewer could just print out a picture of the product and wouldn't need to buy one??? just add scotch tape!

    • Blacklab1 / about 13 years ago / 1

      I still think it would have been cool if they put it on a refrigerator magnet. Then I could put it next to my Bill of Rights Magnet.

  • mbrown9412 / about 13 years ago / 1

    Do we have a datasheet for this?

  • CJG / about 13 years ago / 1

    Ahh .. another item that should be thrown in with resistor orders .. Like over $10 in resistors or something.
    I think I could use an extra one of these once in a while , if only to replace a torn or faded one.

  • ahdavidson / about 14 years ago / 1

    But seriously, SFE, the sticker is a cool idea.
    But how is possibly useful at all, with something that is inherently a color recognition task, to have NO ability to recognize resistors by their color schemes?

    • the colors are written out.

      • MattTheGeek / about 13 years ago / 2

        The human brain works faster comparing colors than reading and then comparing words to a color.
        I like it in Sparkfun Red, However i would love to see a color version.

        • Klone38 / about 13 years ago / 2

          You are correct but for what purpose? it's not like you need that extra speed when putting together a project or a kit. so really there is no difference between colored and labled except for personal preference or a vision disabilty.
          I'm color blind and it really bugs me when i see a resistor chart in only color, so i think this is a very good idea because everyone can read and use it
