A tripod is ideal for shooting some kinds of images. If you need to position and reposition your camera at different heights and angles, an articulated stand -- or an arm with flexible joints -- is worth having. This project shows you how to build one from a desk lamp.
This project comes from DIYHacksandHowTos, who also made the video above. You'll need a desk lamp with a multi-hinged arm to make this work. The tricky part is building a replacement mount for your camera that will keep it stable, support its weight, and still fit nicely onto the lamp where you'll have removed the lamp head and power cord.
In this example, the mount has an extra hinge for flexibility at the camera, so you can position the arm and the camera at different angles if you want. It's a bit like this custom 3D-printed camera jig, but with less specific parts. You can remove the camera freely, and screw in any other camera with a standard mount on the bottom.
