Using an ultrasonic range finder modules from SparkFun and Arduino microcontroller as the controller, Josh over at blog.joshuamcginnis.com has created an awesome DIY sonar distance Twitter buzzer that will tweet the distance he’s sitting/standing from his laptop.

Now, this might look very useless but it can come in handy for security applications or other DIY projects that need status updates via Twitter.

Here’s the screenshot of @hereandaway, which will tell you how far Josh is sitting from the computer:

Great job Josh, let us know on any new updates with your cool sonar project, perhaps you can make a wireless version and stick it on your dog…

arduino & sonar returns your distance away from the computer and it is displayed on the screen. the farther away you are from the computer the larger the text and the greener the screen. the closer you are, the smaller the text and the redder the screen. get within 5 inches and a buzzer alarms. distance is twittered.
