It is neat having a such powerful, small computer.
I have it running off a 32 GB microSD card.
I have an AstroPi Sense-Hat board attached to the Pi 2
The Sense HAT has the following features:
- Gyroscope, accelerometer, and magnetometer sensors
- Temperature and humidity sensors
- Barometric pressure sensor
- 8×8 RGB LED matrix display (that's 64 RGB LEDs)
- Mini joystick

I also have a Raspberry Pi Camera Module attached to my Pi 2.
