Wireless doorbell hacking – Remote PC starting, lighting control, Halloween effects control…

Here’s how to convert a wireless doorbell from HomeDepot to close a relay instead of chiming…This whole thing started from a MAKE forum discussion! “With the addition of one capacitor, one relay, and a small piece of wire we can convert an inexpensive wireless doorbell into a remotely controlled relay useful for a wide range of applications. These include remote PC starting, lighting control, Halloween effects control, or virtually anything that can be controlled by a pair of relay contacts.”Link.

  1. Very cool. I am going to use this to control a fog machine for Halloween. Like you say, the cahllange will be getting a 3v coil. Thanks for the plans.

  2. It’s a nice project, but doesn’t the same store sell wireless christmas light controllers for around the same price as the door chime that’s basically the end result of this project?

  3. Hi all
    My garage door opener has never worked via wireless. I have bought several sending units but they eventually all fail.
    My $16.00 wireless door bell has never failed to work, so, what I am looking for is some simple way to use a wireless door chime to replace the wired push button that activates the garage door.
    [IE a cheap and easy way to bypass the wireless system built into the garage door opener.]

    The wireless door chime I am using is a. Honeywell Portable Wireless Chime & Push
    Model: RCWL100B (Wallmart and Home depot)

    Thanks All!!!
