One of my filthy RICH clients requested a new gadget in his INfiniti FX35 car to impress his friends. He wanted an ALIEN head that pops up from the dashboard whenever he exceeds speed 140 KM/per hour. Making the Alien head that blinks with red LED eyes and speak a few words (like " Fatal speeding, slow down or else !") is all easy to make. But how can I interface this unit with the speedometer, vcan anyone help please ??
