Rather like the excellent D70Box project (see elsewhere on this blog) the Arduino Shackbox project was also published in Practical Wireless.
This really useful device can be made for around £15 and provide a handy GPS controlled clock, locator information, Lat and Long, Worked All Britain Square and much more.
