I got a RaspberryPi for Christmas this year, additionally I have 2 Arduino Uno's that I play around with. No real projects planned just yet for the RPi, but I have been playing around with it. Got a sensor pack on the way and I can use some of the add-ons for the Arduino with it. I got the new RPi v2 (1Gb ram and a quad core processor, 4 USB ports, HDMI and network), running the Raspbian distro it runs really nice, a bit jumpy sometimes when the CPU is taxed but it's been very stable. Plugged in a wireless network USB dongle and the WiFi worked instantly (the RPi board also has a ethernet port). From my winblows box I can remote desktop to the RPi so I can run it "headless" (no monitor, keyboard or mouse hooked up) Running/writing programs in Python, interfacing with the GPIO (General Purpose Input/Output) pins has been fun. Got the kids hooked on it when i showed them a RPi version of Minecraft that I can create mods on. I think one of my bigger plans might be creating a weather station with LCD readout and connecting one or both of the arduio's to the Pi unit.
