“Light Scythe” Lets You Do Huge Light Paintings
Some of you may know “light painting“ it’s a photographic technique which uses long exposures and a light source, to “paint” the photo with light. The project was inspired by the Wifi Netword Visualization, The Mechatronics Guy later brought in the concept of writing and painting pictures with the beams of light with a pc (wirelessly via Xbee).
The hardware is pretty simple. There’s a 2m programmable LED strip inside an acrylic tube, which is controlled from a small receiver and battery pack. A laptop PC with a wireless Xbee link sends the image data to the scythe at a specified time.
