Any other Arduino users/hobbyists? I am a programmer and I've been doing quite a bit of electrical tinkering with Arduino.
Just curious if anyone else has played with this or finds it interesting. Tons of awesome open-sourced projects out there.

The Arduino is pretty cool, especially because of all the pre-done libraries. I find it is not powerful enough for many of the projects I want to do.

What kind of projects are you trying to do?
