An article from theage.com.au warns motorists that thieves who steal a GPS unit from their vehicle can then use the device to find out where the car owner lives and rob their home as well.

This article rang true for me as I recalled about two months ago visiting a large camping store. We were looking at the many GPS units on display and while playing around, I entered my home address to see how quick the unit responded. After playing around for a short while, I went to walk off when my partner enquired as to whether our address would be stored on the unit. After quickly checking, I found our address along with probably 10-15 other addresses from customers who had done the exact same thing.

Needless to say, I deleted our details immediately!

This is a pretty cool video showing a conversion from a petrol run motorcycle to an electric one.

A Honda Rebel motorcycle is converted to a zero emissions electric chopper. Made the Gomi way, with mostly found and scavenged materials, we make a street legal commuter bike perfect for San Francisco.
