If you want to make a clock with an Arduino/Boarduino/AVR, there is a way to hook up a precision 32khz watch crystal

  2. When browsing your blog, I got an anti-virus warning about site 61.155.8.157. When checking the source, there is a traffic statistics link to that ip (located in china). A quick googling brought up this page: http://wordpress.org/support/topic/169123 and mentions of an exploit site.
