I'm no computer programmer nor do i understand basics of electronics... hehe but i just want to share this stuff for all the DIY enthusiasts...
"MAKE's yearly open source hardware guide is now online with over 125
projects in 19 categories. The creators of all of these projects have
decided to publish completely all the source, schematics, firmware,
software, bill of materials, parts list, drawings, and 'board' files to
recreate the hardware. They also allow any use, including commercial. In
other words, you can make a business making and selling any of these
objects. This is similar to open source software like Linux, but
hardware-centric."
Enjoy
