Too many…


Things that go “bzzzz, zap, whirr” in the night.


  • Product PRT-11984 | about a month ago

    Just got 2 of these in. I modified one to fit the Yun and it fits well enough except it has some play. I noticed the holes line up properly on the Yun, but no screws are provided. Can you recommend a screw size for the posts?

  • News - Free Day, Lotteries, and … | about a year ago

    IANAL I would think that the fact that a person does not lose their money either way makes this something other than a lottery. A customer makes a purchase, the result is A: the product was free, or B: the product costs the listed price. Either way the customer gets what they expected: the product. They do not lose any money. This itself should move it away from the intent of lottery law. The intent of lottery law is that you clarify that it is not gambling. There is no gambling or lottery here. You still get the product you intended to get by making a purchase. There is no big prize to draw people. It is simply a case where you might not have to pay.

    You did the right thing here. There was a potential issue, you might need legal advice to clarify this point, and it might be an unnecessary risk. Thanks for sharing your view on this topic. It is a really interesting read.

    Holy crap SF! You helped me solve another engineering problem. I needed a small Arduino/Micro powered off of 12VDC prepacked. This fits the bill. Thanks!

    This looks like an awesome product. It is also priced to sell.

    No human. You are not granted audience to speak with our metal god. Do not attempt to sway my sensory perception with your longitudinally aligned energy fields.

  • Product DEV-11235 | about 2 years ago

    This holds the Uno32 very well. I don’t know if it was really needed, but I trimmed off the tabs that are on the support post that is right under the analog pins. I had trouble getting it to set flat. Everything else lined up fine.

    One suggestion would be to add insulated washers to the kit. There is a trace and a resistor very close to the screw closest to the Sparkfun logo when using this with an Uno32. The screw actually overlaps the trace a bit. If you had an insulated washer it would help prevent someone from possibly damaging the trace or removing the coating on the trace. If you are careful it will not matter, however not everyone is knowledgeable of such mechanical issues until after the fact. ;)

    The old version have the injection mold dots on the bottom of the plate. At least that is what is looks like to me. I think the old one would have to be injection molded to get the clip shape. I would also guess the newer one is the same, but just using a different mold.

    I am stoked. I just ordered these before the product announcement not realizing they are a newer version. Cool!

  • Product DEV-11117 | about 2 years ago

    Thank you Sparkfun making this product. I have been using the Atmega8u2 and they are great. But this is even better! This is amazing work as it looks to be slightly smaller than the 8u2 and has more pins! Good work!

  • News - New Product Friday: The M… | about 2 years ago

    Having a brick and mortar presence is a huge gamble. Brick and mortar stores are going away. It is very quickly becoming an online marketplace for non-perishable goods. That is why Walmart is getting into groceries so they can attract people into the stores. They see the writing on the wall.

    I personally believe Sparkfun provides an excellent product base. Making stores will cut into their bottom line and they will have to raise prices.

    If you want Sparkfun stuff in stores then solicit the stores. They will listen if you find the right people. I know Radio Shaft is now carrying Arduino stuff. I took advantage of that the other day as I needed an AVR programmer in a hurry. So I bought one there. I would love to pick up Sparkfun stuff from them.

No public wish lists :(
