Hello, I have this old toy RC car and a pager and I am wondering if a small hack, using the two is possible or not. The pager doesnt work but its motor does. I want to make a new "pager" that vibrates when the car's remote is used. The car has a small reciever circuit (27MHz if thats of any use) connected up to its own motor and uses 4x1.5V AA batteries. Its remote(transmitter) uses a 9V battery. I would like to make this as small as possible (matchbox size preferably so it fits easily in a pocket). The reciever circuit is pretty small, its the motor that it is connected too, and the 4 batteries that take up a lot of space. Since I have this pager motor lying around I though it would make an ideal replacement for the car motor...greatly reducing the size. And thats as far as I my limited knowledge of circuits takes me :) Is there a way to determine if I can reduce the number of batteries(and hence the space) for the modified circuit? Will reducing the batteries effect the reciever? Also that pager motor is much much smaller than the car motor. Do I risk burning it up? And lastly the antenna is about 7-8inches. Can I bend it to reduce the size? Sorry for all the dumb questions(hopefully not posting in the wrong forum) but any help would be greatly appreciated. Thanks a lot.
