Even if you have steady hands, taking video from very high or low angles can often be a struggle. Luckily, with just about $25 worth of materials, you can make your own camera crane for steady shots at any altitude.
All you need for this project are 2 2x2's, various bolts, some scrap metal, and a stand from an old utility light—the last item may not be something you just have lying around, but any type of tripod stand will likely do, as long as you can connect it to the central pivot point. The project does benefit from welding chops, but if you aren't that experienced you could get by with using screws. You'll probably also need a bucket and some heavy things to put in it to act as a counter-weight, but all that takes is probably a little rifling through some closets or the garage.
Also useful, if you have one, is the addition of the portable DVD player on the operator's end—by plugging it into your camera, you can see what you're shooting much easier. All in all, it's a good weekend's worth of work, but you can't go wrong on the price if it's something you need—hit the link for the full instructions.
