Arduino can be used to develop stand-alone interactive objects or can be connected to software running on a computer (e.g., Macromedia Flash, Processing, Max/MSP, Pure Data, SuperCollider). Currently shipping versions can be purchased pre-assembled; hardware design information is available for those who would like to assemble an Arduino by hand. text/html 2011-08-07T23:14:42-04:00 http://wiki.thinkhole.org/books?rev=1312773282&do=diff 2009 Better: A Surgeon's Notes on Performance (Atul Gawande): A “book of medical stories” on improving performance in medicine, focusing on three areas: Diligence, Doing Right, and Ingenuity.
