Hi there.
I'm new to this forum and id like a little help with my electronics proyect.
ive seen a thread about an frecuency detector but that thread is long time inactive, so id like some help making a new thread.
my proyects is basicaly a device that detects certain kinds of frequencies and shows it in a map like a submarine radar... the thngs i read about where envelope detectors, LM567 and band pass filters. now i have good electronics knowledge but the things i didnt understand about them is how to make the reciever?... my idea was to make a kind of antenna that emits in a straight line, mounting it on a motor to make it spin so it can detect several kinds of devices.
the devices i want to detect are: celular phones (depending on what bands they are), wireless mouses, routers, etc. but my problem is that i dont know how to make the reciever circuit recieve (excuse the redundance).
i want to start out simple making a filter or circuit that recieves a certain frecuency and turns on a LED depending on how close it is, so when its closer itl be bright and when it gets further away ill dim slowly. Then slowly making several circuits to several frecuencys so it can detects the devices. Now the problem persists in how to make the antenna or the reciever circuit.
To complete the idea i want those circuits connected to an arduino so it can identify the diferent voltage inputs to graphic it in an map using a program gnuplot or matplotlib.
so that is basically the idea of my proyect any help or advice would be greatly appreciated ... thanks in advance.
