You'll need a webcam, an old telephoto lens, PVC plumbing materials, and a tripod to steady your telescope. Depending on the telephoto lens, it will affect the magnification of the telescope. Although they might sound expensive, an old telephoto lens can be had for cheap on eBay or in the classifieds—for as low as $US10. If you've got them lying around the house, it's a great way to breathe some life back into outdated gear that's probably collecting dust.

After taking the webcam apart, it will have to be connected to the telephoto lens with the correct piping and endcaps. Next, you'll have to create the housing for the webcam, which will result in a makeshift telescope.

Instructables has the full guide with pictures below to guide you along. Got any cool repurposing projects? Throw 'em our way, and let us know in the comments below.
