  • What's the pitch of the pads? It would be great if the photos shows some examples of soldered components. If the pads are 50 x 100 mil, can you fit a SOIC (50 mil pitch) on it?

  • It looks to me like the only real difference between this and the old color sensor (ADJD-S371) is that the old one had a built in LED. With this one, you'll have to illuminate the object with your own light source.

  • Awesome stuff. I'm guessing that copper is used for the molds because it heats up and cools down quickly. Also, copper is more expensive than aluminum not the other way around, I believe.

  • You guys forgot to put the voltage in the description. Fortunately, it shows in the photo (3V).

  • I don't have the display to try it, but I would assume so. The SPI bus pins should allow you to reprogram it using an ISP programmer. The pins you need are the 6 on the right (when looking at the bottom of the board). Note that the silkscreen reads "SI" and "SO" for the MOSI and MISO pins.

  • That seems strange that your project isn't working with a floating ground. What kind of sensors are you using?
    If you really need a true ground, just connect a ground pin on your Arduino to ground directly. You don't need the power supply to do it for you.

  • The product description says "Center-positive 5.5x2.1mm barrel connector."

  • What do you mean the equation in the datasheet doesn't work? The equation is the "extended" Steinhart-Hart, so it has an extra squared term, but it's essentially the same.

  • Cool!

  • Why doesn't SparkFun sell a heat sink to go with this?

No public wish lists :(
