Do me this MP3 ordered doorbell after I got an idea while looking the series "Stargate". I have known all the Stargate fans saying "Unscheduled off-world activation" cut out of a series and worked with an audio editor a bit. Then connect the doorbell just to the PC. After a few seconds (can take up to one minute) is detected the bell as a mass storage. Grab the sound as MP3 on the doorbell and you're good to go.
If now one with us Zuhaue on the door bell I hear from Walter "Unscheduled off-world activation!" Just awesome!
For battery life I can currently say anything yet, because the ringing until a week is in operation. For those interested, here where I've cut out the sentence the point. Season 6 Episode 21 at 9 minutes and 41 seconds. If you are interested I would but my MP3 File Available simply post a new comment.
