Most cellphones are provided with a very basic wall-wart charger, and you usually have to pay extra for a proper charging dock. The bundled charger is often unsightly in use, being just a transformer with a cord strung out to an end table or someplace where the cellphone rests. If you have a cat who likes to chew through cords, as I do, this can be more than just inelegant — it can be totally impractical. It’s also a good project if you just hate, for aesthetic reasons, loose power cords strung out across the furniture.
A similar product is for sale at ThinkGeek, and that’s where I got the idea. The nice thing about my version is that it requires no tools to mount or demount, being suspended by the plug on the charger itself. So you can quickly move it around to whatever outlet you want or take it with you when you travel. Plus it costs all of nothing to build.
