The PIN digits you punch into an ATM’s keypad to authenticate your transactions are leaving traces of themselves behind in the form of heat, says a paper recently presented by a team of UC San Diego security researchers. Someone following immediately behind an ATM user can use a digital infrared camera to determine what keys were pushed with about 80 percent accuracy, their study shows. Even a full minute later the camera can pick up the correct digits about half the time.
It's neat that you can see your house from space, thanks to Google and Bing maps, but cluttered images of rooftops and streets don't give you much besides street directions. A Belgian project aims to change that by adding infrared imagery, allowing Antwerp homeowners to check their homes' insulation capabilities.
The thermal map shown above was generated from an aircraft flying low over Antwerp and surrounding areas, on four cold nights in March 2009. The map indicates heat loss from the rooftops, according to the infrared map project.

If you're looking for an easy way to add DC motor control to your next Arduino project, look no further than the Orangutan LV-168 Robot Controller by Pololu. Equipped with two bidirectional, low-voltage, H-bridge motor controls, this ATmega168 board can handle many of the tasks that are typically sought by Arduino DIYers. Plus you won't have to monkey around with lots of complex programming, either.
