You still fail my challenge: design a wireless doorbell that has a user-configurable chime (eg. MP3 file provided by user), in a way that uses less software or less hardware than mine. You couldn't.
Then I want you to justify why commercial products offering this feature have 10-100 times more code or 10 times more complex hardware just to do what my doorbell does :-)
