Not Your Average Door Bell
Solar botics
November 25, 2011
Wireless doorbells have a tendency to... suck. I speak from personal experience on such matters. When they fail to get my attention while at home, apathy generally wins out and inevitably forces me to head down to the FedEx/UPS depot to pick up my missed package. David Watson, a man of action, took matters into his own hands.
David built a custom door bell that strikes children's resonator bells using a custom designed Arduino clone and our GM10 geared pager motors, inspired by the Solar Xylophone featured in Make Magazine. Utilitizing the home's existing wiring for a doorbell hidden behind the installed wireless solution, David ended up with something far more elegant that we think is just fantastic:
Keep up the good work David!
