Hey guys, I understand remote control cars and such use their little antennas and shoot radio waves to the car and control it... My question is can I make some kind of device such that I can remove the antenna on the car and instead hook up to the reciever a digital input processor which will interface between a digital signal and change it into what would be the radio waves the car receives? Basically in a normal setup you have: Remote->Radio waves->car antenna->wave processing device But I want to do this: Digital Remote->10010100->digital receiver (on car)->*digital to radio wave converter*-> wave processing device. The asterisked part is the toughy. I think i need some kind of part or a couple of them. hmmm any help?
