I found the Make Getting Started with Netduino kits on clearance at Radio Shack for $20, so I decided to pick one up (rescuing more clearance items). Figured it would be a good way for me to get my feet wet in the Arduino and microcontroller world.
The board it self is pretty small, maybe a little smaller than 10x10cm.
The kit contains everything you need for the basics like making LEDs blink, a little speaker, a little bread board for prototyping and even a servo motor.
There's even a MakerShield included for building your own Arduino shield.
I'll have to deal with C# and .NET, but I don't think it should be too difficult. I'm looking forward to learning and playing with it.
