Hi all, thanks to all your brilliant help, iv'e managed to make a remote pc Opperated Vibrator (pager) if someone says my name on irc the pager turns on and vibrates until i get to the pc to turn it off.. (Not brilliant I know) but its a start for my first ever project.

At present, im connecting the circuitry via leads, now Today my AM-RT4 (transmitter) and my AM-HRR3 (reciver) arrived (Data sheets included at end) I am wonder how and IF it would be possible to use these to turn the device into a shortrange wireless device that will in turn, turn a relay on to power the pager ? i was doing great.. rattling along until i looked at the datasheets for these.. :( radio signals and such are confusing :(

Any advice and help appreatiated :)

Below is what ive done.. (works on breadboard)

hope this helps.. Trying to put the device in between the relay and motor, to eliminate the wires.

Unfortunately the datasheets not visible for me, but Your circuit can work only with NPN transistor, and - i think - no need relais for a small motor.
