If your phone supports wireless charging, but you don't want to clutter your nightstand with an ugly charging pad, you can build it straight into the furniture.
The video above does a great job of walking you through the process, but basically you'll use a chisel or router to create a cavity on the underside of the top of the nightstand, then slide the charger into place. The video uses an IKEA Hemnes nightstand and a Nokia Qi charger, but the basic steps should be similar no matter what you're working with. This particular arrangement does allow the charger to rest on the side wall of the nightstand, but if you aren't so lucky, a thin piece of scrap wood or metal will keep it from falling.
This is similar to a previously-mentioned project that added a PowerMat charger to a bookshelf, but this one doesn't require you to disassemble the charging base or permanently attach it to any furniture.
