You hungry for some pi.

Raspi_Colour_RThe other day I was reading up on microcontrollers. Wikipedia calls them, a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. When I ran across this little gem called a raspberry pi. It is a complete computer that runs off a compiled linux kernel. This thing is pretty awesome. Check out the Stats below. If you want your kids to learn how fun and power programming can be, this is your low cost entry into it. For about 80 bucks you can get a great starter kit with lessons on programming for the kids.
