They're pretty neat. This intructable will show you how to make a device that sends your voice or any other form of audio over a beam of light. The picture below is the finished product. I found the information on this projecthere. Please note that I used a lot of salvaged parts fo...
There are multiple reasons why your headlight stopped working—and none of them are good. Here's a step-by-step guide on how to replace the part that is broken.
"To obtain an idea of the size of a light-year, take the circumference of the Earth (24,900 miles), lay it out in a straight line, multiply the length of the line by 7.5 (the corresponding distance is one light-second), then place 31.6 million similar lines end to end," NASA's ...

Light painting, a technique practiced since the dawn of photography, is now mostly associated with moving light sources in front of the lens to ‘paint’ shapes. However, there are other—more complex—applications and uses of light painting that offer plenty more variety to get creative. Here...
Thus, they reduce their life significantly. This is a huge drawback asdimmer switchesare an awesome way of cutting energy costs. So, if you want dimmable lighting and like to get it done efficiently, LEDs are dimmable lighting solutions that will work for you. ...
When you cross the beam of light, you block it. The photodetector senses the lack of light and triggers a bell. You can imagine how this same type of sensor could act as a smoke detector. If it ever got smoky enough in the store to block the light beam sufficiently, the bell would...
3. Draw in marker lines for large sections. Find the lines of the car body. “I like to think of it as a block of clay you’re carving a car out of,” says House. Sketch out a front quadrant to designate where the hood and windscreen go. Then mark the front bumper. Drawing the...
