  • Looks like “ground” is not broken out. Wouldn’t any real hacking (like adding a filter or such) require ground? I know I can add a cable, but if I want to keep it in the enclosure a broken out ground pin would have been really useful…

  • Not sure on this one - the 20Mhz might be a problem. Arduino setup is usually either 8Mhz or 16Mhz - so the timing routines need to be changed (milliseconds and microseconds and such). Probably just selecting a different prescaler…

  • Both, the ATMega328 and the ATMega168, are rated up to 20Mhz - so just connect a 20Mhz crystal and you are good to go.

  • I completely missed that… Thanks!

  • Shouldn’t it say somewhere, that this replaces PGM-11460…

  • I don’t understand why it would be very hard to run a 5 meter addressable strip (5 * 60 = 300 LEDs) with an Uno. What are your concerns? Is it power consumption? In worst case (all on) you would need 18A so the 500mA that an Uno can provide is not enough, but any 5V/20A external power supply will fix this. Is it RAM? You need 900 bytes - no problem for an Uno.

  • Is this the SparkFun wish list? I want a CC3000 breakout board…

  • Thanks for the new LED - I put it in an it worked right away. Great customer service!

  • SparkFun: I think you put the wrong RGB diode in the kit. There should have been a common cathode, but you used a common anode. I cannot get the LED to work, but if I connect 5v the the shield ground and gnd (with a resistor) to pin 3, 5, or 6 it works! Suggestions?

  • There was another good article on Slashdot this week “KWin Maintainer: Fanboys and Trolls Are the Cancer Killing Free Software”. Might apply to Open Hardware too…
