It works for me! Now drawing is another story.

See even more of our drawings on Flickr.

My next Instructable will outline our techniques for actually doing the art. In the mean time see the Write or Draw with Light Instructable.

wow u have to move like super fast to draw those in the air tolatly amazing
 They do it by setting the camera to stay open and sensing light for a really long peroid of time. So it captures all the movments of the light pen in one image. CReating the drawing. So they can move as slow as they like. :)

i dont get how the photograph sees the whole picture? does the person there see only what is happening that moment or does the camera capture the finished product despite being invisible to the human eye. if so how does it capture it?

It is strange, but unlike the human eye, any light that enters the camera permanently changes the film or, in the digital camera, is permanently recorded by the optical image sensor and is displayed as a picture. Light entering our eye is retained on the retina (or maybe in the brain) for less then 1/25 of a second. This video might help: http://lightdoodles.com/pages/drawing1.htm

? I dont get it how do you make those pictures? by moving fast the LED light?
unklstuart (author)  m4r7in5 years ago
It is not easy to show as you are working in a low or no light environment. I try to illustrate it with video in this tutorial http://lightdoodles.com/pages/drawing1.htm

Awesome intructable! for the power supply, couldn't you use one of those 3V button cell batteries? i have tried them and all my LEDs have worked, and it eliminates the need for a resistor. i can post a picture of this battery if you'd like.
unklstuart (author)  aeronut015 years ago
Thanks. When you consider the internal resistance of the battery and the tolerance of the LEDs, the 3v cell works. But since these blue LEDs prefer a forward voltage of 4v, I thought I would be nice and give it to them.

using the led pen can draw a pic on a wall or..? if anyone know where to buy pls let me know thx... joan1986@live.com.my :P
unklstuart (author)  sw33t5 years ago
Most of our pictures are drawn directly toward the camera, but you can point the lights at a wall and draw there. The results will be different and may appear more like spray paint. Try using a laser pointer when drawing on a wall. The concentrated beam will give a more defined image. Any light source can work. LED lights on key chains are available in most stores and work well for this. thanks
