Gavin of Sydney, Australia created an awesome 2-meter long programmable staff that makes painting giant words and images as easy as waving/walking the staff around during a long-exposure photograph. The staff, which he call the LightScythe (we would have called it the “Lightsaber”), was inspired by the Wi-Fi light painting project we shared here earlier this year.
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. [#]
Here’s one of the most creative examples of light painting and long-exposure photography we’ve seen — a few techie guys built a special 12-foot-long rod with 80 LED lights that light up depending on how strong a particular Wi-Fi signal is. By walking the stick around and capturing the lights in real time, they were able to photograph “light charts” showing how a particular Wi-Fi signal strength fluctuates in a particular area.
I had some stuff lying around as well as saw some parts as I was out and thought this would be fun to make. I have around $20 invested in parts. On eBay I saw ring lights for anywhere around $40 on up, so this will save you money and it was fun to make.
If cameras can have external flashes, why can’t mobile phones? The iFlash is a flash module that allows owners of older iPhones to illuminate dark scenes with a blast of LED light. iPhone 4 owners can also use it to gain some additional light.
