DIY Nightvision Headset
A very interesting project from KipKay (you might have heard of him through Metacafe): recycle a broken or obsolete camcorder and make a night vision camera out of its viewfinder. You’ll also need a few other components for this build but all the parts are reasonably inexpensive, considering the result. Best of all, you can output the video to record on a camcorder.
