I need help with a remote circuit.
So here's my story: I want to impress my rc car club teacher person guy by building my own rc car from scratch, but I already have an idea about how to control it and stuff. I just need to make a rc circuit. Basically I need a radio transmitter that can be made with minimal parts, no i.c.'s, and it has to transmit at least 50 feet. And I need a reciever to pick up the radio signals and this also has to be minimal components, no i.c.'s, and it has to pick up the radio signals of the controller. I was expecting the signal to be in the khz section because it's easier to make that. So someone please give me a link or schematic for this. And also, the parts have to be what radioshack supplies. HELP!!!!!!!!!!!!!
