Add a watch crystal to a Boarduino


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

mtbf0 shows you how!
pictured above is his LCD clockduino!

Trialex followed up with a really-big-7-segment clock (in the same thread)

    (It really was 4:16 when I took the photo, even though my camera disagrees.)

  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.

  3. wordpress has been upgraded! hopefully that will fix the problems

  4. I’m the only one in this world. Can please someone join me in this life? Or maybe death…
