Trossen Robotics puts together some cool contests! This Automatic Deadbolt System was the second prize winner in the latest contest. I could just imagine how it could be used, hold on I will unlock the door for you, darn I don’t have a good signal with my cell phone, hold on I will walk over to the door and manually turn the knob to let you in.
Thanks to Dave (fish123456) for creating this cool invention.
"I was inspired to do this project when I saw some of the other uses that an RFID passive reader has been used for. I noticed that many people have created a system whereby they install a reader on the outside of their front door and use an RFID tag to unlock it, and let themselves in. I wanted even more control over my front door, so I added the ability to remotely lock/unlock the door from any computer with internet access, or as is shown in the video, a cell phone. Now I can control access to my house from anywhere. In addition, I found that the RFID key fob I used would charge even on the other side of the door and transmit back to the reader through the door. Now I don’t have to worry about mounting something on the outside of my door, which makes it that less "interesting" for would be thieves or passerbys (and makes it much less aggravating for my land lord! ) Thanks for running these contests, they are a great way to expo projects.
