Generally, when I shoot pics with my DSRL I don't have a problem with blur if I am outside where it is bright thanks to a really fast shutter. Inside or when I try to shoot pics in the dark things are different though. I end up with blur almost every time thanks to the fact that my D80 lacks any anti-blur tech inside.
I guess I could buy a lens that has the technology in it, but I rarely need it. If you are like me and don't want to spend the money, it costs to get a lens to reduce blur in your pics and you have a DIY penchant this new hack at Hack A Day might be just what you need. The builder took an Arduino board and connected it with a Bluetooth modem, 3-axis accelerometer, gyroscope, and a camera trigger.
The smaller camera you see on the side isn't a part of the final rig and is there to help tweak the algorithm that removes blur. The final product controls the camera shutter and supposedly does a good job of removing image blur. I think I'd rather just fight the blur or buy a lens that have to use that thing, but it is really cool.
