This project shows how to build an Arduino based GPS system capable of displaying the current location, heading, speed, average speed and maximum speed, the distance traveled, the bearing, distance and ETA for a way-point, and the date and time. This unit can also be used for Geocaching. It is using SparkFun GPS Shield and Nuelectronics LCD Keypad Shield together in a useful way. [via]

Photoduino is an open-source driver for cameras based on the Arduino platform. Its main purpose is to serve as technical support for taking photographs of various techniques such as: Timelapse, High Speed Photography, Photography of insects and animals, or storms, HDR, among others.
The circuit containing the electronic control is capable of auto focus and the shutter of a camera and shot up two flashes manuals. It also has a sound sensor, an impact sensor, a laser barrier infrared barrier that can be used to take pictures when you register an event.

This project shows how to use an Arduino to read the signal from a set of digital calipers and send the reading over USB. In other words it adds USB functionality to digital calipers. A great reference on reading digital callipers can be found here . This project explores the details of another protocol found to be in use on some callipers. Check project details on the link below.
