Arduino Starter Pack
This looks really cool. It's a microcontroller with everything that you need to get started. You get the controller module, a mini-breadboard for adding hardware to the controller, power supply, batter holder, USB cable, and assorted LED's and other components for fun. You plug the device into a USB port (Windows/Mac/Linux) and use a supplied application to program it in C.
It looks like a very easy way to dig into hardware with the foundation already taken care of. As a big fan of robotics and hobbyist tinkering in general, I'm very tempted to get this! You could easily hook up a few sensors and a serial port LCD display and make some nifty gadgets. There's some good support for it including tutorials, forums, and ideas. Anyone have any experience with it?
