The AArduino
Although the Arduino is very convenient, I wanted to build my own from parts you can buy from RS or Farnell. Rather than cloning the Arduino, I took the opportunity to make some changes: I removed the USB/Serial interface because I've got a ICSP programmer, but added crude support for dual AA battery support. The AA cells suggest a good name: the AArduino!
