Have teenagers who lock themselves away playing their online games with headphones on? Tired of them not hearing you yell for them or not answering their text messages or calls? Yeah… US TOO! That is what the motivation for my latest gizmo is driven by (Plus it was just fun to build). Park this little gem right in front of their screen. While it’s quiet, it is just sitting there minding its own business. But…when you send it a message, it gets a little OBNOXIOUS and beeps and blinks LED’S along with your message on the LCD… DEFINITELY getting your precious teen’s attention.
