I heard about Hackerspaces.org at AltExpo at the New Hampshire Free State Project's Porcupine Festival. I started looking through the list of worldwide Hackerspaces projects at http://hackerspaces.org/wiki/Projects and found this one, which seemed worth sharing here. It's from http://hackerspaces.org/wiki/GPS_cruise_control,_speeds_up_~ and it says partly as follows.
GPS cruise control, speeds up automatically
Why To avoid unnecessary speeding tickets
Who Jim Pruett
