My Doorbell

by Trish and Baila

Published on April 23, 2014

We are almost ready to leave on our year long cross-country RV adventure, and Baila created a doorbell for her bunk.  If her shade is down, we can ring her doorbell. If she is available, the sign will light up! My favorite part of her invention, is the /and/ bit which provides feedback while a visitor is pressing the doorbell!
