You are probably aware of the problem: how to ensure a minimum of security when you back out of a private property in a car, without visibility. Most of the time, people simply back out really slowly and hope that no one bumps into them. But you are still at the mercy of a distracted driver. Hence the idea of a light barrier triggering a light signal to warn oncoming traffic of the danger.
This week, we show you how to build a bar lamp based on RGB LEDs. It's easy and you will end up with something almost as pretty as those you may find in your favorite appliance store. Moreover, each LEDs can be controlled individually, which is not a common feature among design lamps.
