Build a wireless signal transmitter from scratch?
I would like to build a small wireless transmitter that could be able to send audio signals (like a walkie-talkie) and whose antenna could be a small parabolic dish. If it can also be used to activate switches (this one is for my science project), better. It must be home-made and cheap, ok??
BTW, i alredy googled this question, but what i only saw was things that envolved very complicated electronics. By the way, is any way that this device can sen video signals paralel to the audio signals? like, for example, connecting my cam through a video entrance and then a screen on the receiver would show the image? thx
The simplest you can build is an AM radio transmitter.
Lots of designs in the Internet
Here is one

You can also build a very simple AM radio receiver, which you can use to activate whatever you want.
