Open source Project / Hardware

Sure, but don't you find this less confusing:

"Arduino" refers to so many things:

  • open software
  • open hardware designs
  • many many tutorials and documents of unknown copyright,
  • a community
  • a way of learning and doing electronics.

Whereas the anmes of the boards are crystal-clear:
Diecimila = Arduino team produced board
Barebones = Paul Badger's board
Arduino Runtime= NKC electronics' board
Carduino= your board

People know the difference.

The "confusion" claim, i.e. that people will mix up who makes what product, doesn't pan out. Trademarking Arduino would be more about protecting the franchise that extends beyond the boards: community, hardware design control, etc. I'm saying that maybe that should be totally open, name and all. We can still have high-quality Diecimila boards. It's not like anyone is goign to run out and make copies so that they can shave that extra $4 off the profit margin.... it's not worth their while.

Anyway it has the same ring as Suse Linux, RedHat Linux, etc, so we need to be at least able to freely use the Arduino name under license, that much is clear.
