The USB Doorbell replaces your current chime and allows you to play your favorite sound effects, music, audio clips, movie quotes etc.

We are used to be able to have a custom ringtone on our cellphones, so why not have a custom ringtone on our doorbells.
Via USB you can upload any up-to-thirty second WAV or MP3 soundclip on the USB Doorbell.
It has three different volume settings and a mounting loop for attaching the USB Doorbell to a small screw or hook. Your new cool doorbell is powered by three AA batteries (they are not included).

Everyone's favorite gadget shop Think Geek sells the USB Doorbell for $99.99.
Think Geek also has a video showing the USB Doorbell in action.

Important installation information:
The USB Doorbell is NOT a wireless doorbell. It is designed to be used in homes with pre-wired LOW VOLTAGE doorbell systems (which is the standard doorbell system). The USB Doorbell does not include a step down transformer, and is only designed to be used within a low voltage circuit (4-24 V). If you are unsure where your step down transformer is in relation to your current chime unit(s), do some research first! Occasionally they are attached to the chime itself, hence replacing your current chime may also remove the transformer. There are plenty of DIY websites out there that can help you figure out the details!
