  • Perhaps you should look at alternatives to the clamshell packaging. Packaging items in clear reusable plastic containers would be cool, and could mean a little bit less trash in the environment.

    • Retail packaging is not for you, it’s for the dealers that hang them on pegs at their store. Sparkfun is a distributor.

      • I realize that, but it would be interesting if instead of using clamshell, they used some kind of reusable packaging for their retail products like low quality part boxes. Just an idea. It will probably never happen.

  • Is that battery just floating around inside?
    If so it could easily short…

    • Yeah, but it touches only plastic, all the other stuff is in bags.

      • Sadly not, the battery and resistors are free floating behind a plastic tray holding the LEDs, so like the one I just got, you get a nice dead battery.

        • Bummer, they shouldn’t be packed like that. I’ll revise the packing procedure so that doesn’t happen anymore.
          If you want, contact cservice@sparkfun.com and we can get you a new battery, just tell em I sent ya.

          • I’ve check it and it is free-floating, but the resistors are bagged and there’s nothing else for it to touch, aside from the rest of the enclosure. We’re going to revise it to be bagged and check if our supply had dead batteries.
            Thanks for bringing it to our attention.

            • Sadly, I bought two of these today from my local Micro Center and the batteries were both dead.

              • We’ve just recently started bagging the batteries individually and using a new supplier for them. If you get one of the old kits, contact cservice@sparkfun.com and they can help you out.

      Of course the battery is just floating around, you expect the same people who design your breakout boards and maintain this website to have that kind of common sense? I mean, as tempting as it is to give it its very own Earth-killing plastic clamshell, if you did that then the Toddlers couldn’t get to them to swallow them, and that is, after all, the real reason it’s included.
      (this is sarcastic comedy: I think plastic’s fine, of course the battery isn’t just tossed in and I don’t want to hurt your toddler… the battery-swallowing is a legitimate concern, just don’t give your little kid a plastic box full of LEDs to play wth)

  • The info sheet doesn’t have Amperage numbers. I’m not sure how to build bigger circuits and get the correct resistors without it.

    For example, I found an equation to use that goes like this… For a 20mA LED, then the required resistor value would be R = (Vbat - Vled)/20ma.

    Obviously I don’t want to overstress my LED and turn it into trash.

    • It doesn’t look like there’s any specifically low current LEDs in this assortment, so when in doubt about the rest, 20mA is usually a safe assumption for maximum current for a single site LED. Try staying a bit below that, e.g. 18mA if you want to run them for longer periods.

  • how do we tell the difference between all the clear leds?

    • using a multimeter on the diode setting is a great way to identify an LED. it will dimly illuminate the LED when polarity is correct.

    • The RGBs should be easy to pick out, and with the others, start with the minimum 2v and power them all up. You should be able to narrow them down quickly from there.

  • Is the RGB LED a common anode or common cathode?

  • willl this stuff just plug op to the battery or does it need seperate items to run

  • Are these 5mm LEDs? The link to the Info Sheet is dead.

  • good and blinky fun

  • 30 LED’s but only 25 resistors?

    • There’s actually only 26 LED’s but I understand you including the 4 extra pins on the RGB LED’s and you do make a good point.

  • Parents of infants and toddlers around should be careful that their little ones don’t ingest coin cell batteries (I didn’t know this until I was a parent myself). Check out http://www.poison.org/battery/guideline.asp for more info. Perhaps Sparkfun should reconsider the possible unnecessary inclusion of the battery with this package. Most people have a battery or power source already available.

    • Plastic packaging, LEDs, and resistors are also vary harmful to ingest. I don’t think Sparkfun would omit those items as well for safety reasons.

    • Perhaps you should just keep dangerous objects away from your children and if you are so concerned about it don’t buy this product.

    • About half the stuff on this site could injure a toddler.

    • I think they were going for something that included everything you need to get started. (For someone that is new to electronics and might not have a battery.)
