    Does anyone know of some kind of WiFi controllable switch that will reverse polarity of a peerp source?

    I have an ac/DC converter running to a DC motor, but need it to run in both directions, controllable from a smart phone.

    Let Google be your friend and search for "cellphone controlled relays" or some similar search string. Lots of products available, some more expensive than others, some with more than one channel of control. Product you select will depend on type of cellphone (CDMA or GSM) and/or whether you want to use a Bluetooth or WiFi interface.
