[SOLVED] heath/zenith wireless doorbell chime connection

[davidbenjamindix]

i purchased a heath/zenith wireless doorbell chime kit (model # SL-6147-WH) that runs off of (2) 1.5 volt batteres, which produces 3V through the doorbell. i then detached the speaker, and am trying to use the doorbell to power a 3V DC motor. (range 1.5-3V). the volts running through the wires where the speaker was soldered is about 3.1V. the motor works because i've tested it with 1.5V and 3V. also, when i depress the push button for the doorbell and the motor is connected, i can hear the vibrations of the 'chime' through the motor. the problem is that the motor is not turning when i depress the button. i wondered if maybe the signal being driven to the motor is sound signal only? are there resistors that need to be taken out? or maybe a transistor? im just starting to learn about electricity, so i definitely need help.

You can buy ready made RF transmitter and receiver modules from digikey and other sources.

If the door-bell was a traditional 'bell & striker' or a stand-alone, DC-powered 'sounder', your plan might work. As it is, I reckon the speaker is fed with AC, which will not turn the motor continuously...

You *could* try feeding the AC to a small bridge rectifier and its DC to the tiny motor. You'd lose 1.4 Volts to the diodes, but the motor may spin...

IMHO, it would only need 1 Amp & 50 volts rating-- The latter because of the Back-EMF 'spikes' off the motor...
