Desenhar com LEDs
O Hackedgadgets publicou um artigo no qual apresenta-nos LEDs que servem como canetas para desenharmos aquilo que vem na nossa imaginação e fazermos combinações muito interessantes. O artigo mostra uma variedade delas, umas estão mesmo muito porreiras.
LEDs are wonderful items, they don’t need much power, they are cool to the touch and come in many colors. This is the perfect combination for drawing with them. If your camera has a long exposure mode you are in luck. Just like the long exposure pictures we have all seen of city streets showing all the car tail lights streaming through the streets, you can use the same effect to make your own drawings. Light Doodles has put together an good article that shows how to put together an LED wand that they use to make their creations. Many people are using flashlights to get similar results using the same procedure but I am partial to using LEDs for the best effect.
