I have a question for all ou electrical engineers out there. I have this toy shaped like a cow where you press a button and it sings "Old McDonald". If you press the button again it turns off. The song plays twice and then finishes. If you hold down the button it will still only play twice through.

I live in a dorm and the point is to put this in somebodys room and just fuck with them.

On the switch, there are just 2 wires and it has a little button on it. I want to create a remote control type deal so when i press the remote control it turns on and off. How do I build one that will do this? Your help is greatly appreciated.

It could be done with a rc car reciver with a relay wired in place of a servo, and you just use the rc remote, but that may be too costly for a joke.

im looking less than $20. if anybody has any input i would greatly appreciate it.

i remember when i was a kid (wait, i still am ) at toys'r'us they sold really shitty rc cars for like 9 bucks that went forward and did a left turn/reverse i'm sure that will do... you may get some odd looks wolking though toys'r'us tho :-P

hmm...do you think rat shack might have something im looking for that is easy to make?

Probably, but I don't think you'll be getting your stuff for under $20 there.

What about that Wireless on off switch someone made for the tutorials in the lik-sang competition...

Thats quite good. u could easily do it cheap aswell

is this the one you were talking about: http://www.xbox-scene.com/articles/rf-power.php

can i disconnect the speaker from the receiver and have it still work or would i need to put in a resistor or something?

what about a wireless doorbell, that should be pretty easy to hook up.
