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!
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?
A resistor identification tool that isn’t in color?

Another minor thing to note, and ask about.
There is no through-hole on the board right under the SparkFun logo, nor are there any in the last row where “sparkfun.com” is screened on the top. This means you can not use an 8-pin header in either of the last two rows, which would be handy for an off-board connector.
It seems you could put the holes there and move the logo to the reverse side to make it more useful.
One last thing about instructions:
Another warning about soldering the LEDs in the correct orientation is probably even more important than the one about the resistors. Resistors are symmetrical, so it doesn’t matter which way you insert them, but LEDs are not!
People not familiar with the schematic symbology won’t know about which side of the LED illustration on the board represents the cathode and which is the anode, and whether the short or long lead is anode or cathode.
This really should be noted in instructions!
3. Instructions: I know your product page clearly says that you don’t ship assembly instructions, but I think a simple note with some basic pointers in it would be useful. Here are some examples:
- Figure out which is the red LED and solder it on the board in the spot marked POWER. Figure out which is the green LED and solder it in the STAT spot.
- Check the resistors carefully! One is 10K ohm and the other two are 330 ohm. The slots on the board are marked correspondingly. Be sure to match the resistors with the right slot when you solder them on the board.
I wouldn’t underestimate the value of very simple instructions or tutorials. They go a long way towards helping people get going with the technology. (I can read a schematic, but I bet not all early users of these tools can.) ladyada, for example, has done an excellent job of making useful instructions.
I DO like your taste in musical inspiration!
I don’t know about the annular ring size since I just got this kit and haven’t soldered it yet. And I haven’t used it yet, so can’t render an opinion about the power buses.
But here are a few other comments on the kit:
1. LEDs: I don’t know that the bright ones are really necessary, nor do they need to be 5mm. The smaller 3mm basic ones, like in the SFE store, would be just fine, I think.
Furthermore, I know it’s very minor, but with the clear LEDs, you have to actually plug them in first to figure out which one is green and which is red.
2. Parts list: I think there is an error in the parts list for the connectors on the web page.
Doesn’t the shield require 9 of the 8-pin female headers and 1 of the 6-pin female headers? The description says 11 and 1. (My kit was missing the 6-pin, by the way.)
Shouldn’t there also be two 2-pin headers included as well, for the two ground and two +5V pins along the edge of the board (at the ends of the digital pins)? The main photo of the shield on the site shows them in place, but they aren’t in the parts list (nor were they in my kit).
No public wish lists :(
