Monochrome LCD
This is my 20 x 4 monochrome LCD. I have connected it via a parellel interface as I need more features than the 3-wire interface can do (special characters, Blink function etc). But here is a tutorial on both methods->

You can use the parallel interface to connect multiple LCDs. All the pins(5) can be shared except you would use a separate enable wire for each additional LCD and separate contrast pot. This is discussed on the arduino forum (with pictures!).
Other connection methods are Serial or I2C (Arduino Library).
I also have a I2C LCD from DFRobot- which I used for one of the Arduino bots. I love my I2C LCD, so simple and only uses 2 analog pins + these can be shared with other I2C devices.
ADXL335
Testing out my new 3-axis accelerometer by Sparkfun (ADXL335) . Almost too easy to wire to the arduino. Functional first time. Now just to interpret the data…
Locosys LS20031 GPS module
Acquired a Locosys LS20031 GPS module. This will eventually be put together with the accelerometer, Piezo, thermistor and any other sensors i have lying around for my Black box project- will post project soon.

TinyGPS library: TinyGPS10.zip from http://arduiniana.org/libraries/tinygps/
Piezo element
The piezo can detect knocks or vibrations. Also can be used as buzzer.
