This project is a nixie tube reverse geocache box which unlocks to reveal its contents only when it’s in a certain place on the globe. It uses an Arduino, a GPS sensor, and three nixie tubes, which indicate the box’s distance from that special spot. When the button is pressed in that spot, a servo motor unlatches the lid. [via]

I have used the transparent UART mode of the Bus Pirate to directly access the serial data and send it to other third party softwares to show my location on google maps.

This project shows how to build a GPS based clock. This clock is able to display accurate time received from a cheap GPS module. The clock is based on PIC18F1320 and uses MAX6951 LED display drivers.

This project shows how to build an Open source hardware GPS based on GeoShield and Arduino and if you combine it and a TouchShield Slide, you have a completely portable DIY GPS. Check details of this project on the link below.

This project uses the features of Arduino to make a motorbike computer. It uses an Arduino Duemilanove, Adafruit GPS logger shield kit, USGlobalSat GPS Module, Standard LCD 20×4, Breadboard Power Supply, Polycarbonate Electronics Enclosure to build it. The unit shows GPS coordinates, direction, temperature etc. Check details on the link below.

This project is a box that is linked to a certain coordinate on earth. The challenge is to find this coordinate, in order to access the contents of the box. The GeoCache Box is based on a PIC18F2520 microcontroller that is interfaced to GPS receiver and it has a LCD and a lock. [via] Markus at jave.de writes:
Other than with ordinary GeoCaches you do not need to find the box at the target coordinate: You will already have it when the puzzle starts. But the box is closed and it will only open when you are near the target coordinate. In order to find the coordinate, the box has a button: When you press the button, the internal GPS receiver will detect the current location and the distance to the target will be displayed. Of course the number of trials is limited. If you press the button too often, the box will be sealed forever.

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]

Parallel Track is a web application for displaying the position of one of more vehicles on a map coded in PHP. It was originally designed to work with Telit’s Python supporting modules http://www.telit.com/en/products.php but can be updated by anyone that knows PHP to work with custom tracking projects. Check more info on the link below.

DIY is cheaper and often better, as Justin Lee and Oliver Yeh found out when they decided to send a camera into space. The two students from MIT put together a low-budget rig to fly a camera high enough to photograph the curvature of the Earth. Instead of rockets, boosters and expensive control systems, they filled a weather balloon with helium and hung a styrofoam beer cooler underneath to carry a cheap Canon A470 compact camera. Instant hand warmers kept things from freezing up and made sure the batteries stayed warm enough to work. [via]
