Is there any other project that you think would be nice to do? It has to be all analog (for example, a friend of mine did a theremin)
Wireless energy transfer would be a nice one:-D
Thanks FvM. That was the kind of things I need to know.
So I have to stop with this project

I'm trying to re-transmit it, because I think that's what I have to do to reach a larger place. I couldn't find what's different between a booster and a re-transmitter.
Why not build an FM radio? Some fundamentals to be learned there, plus u get to do field tests.

There are a lot of FM radio projects and I really would like to make it, but I would need to know which one works better, which one can be explained better, and what things do I have to be careful with when I build it.
Do you have any experience in this field? Can you help me?
Thanks!
I purchased an FM transmitter kit from an electronics mail-order house. I followed a schematic to solder a couple dozen parts onto a pcb. Power was from a 9V battery.
It worked fine once I picked up the transmission. I spoke into the included electret mic. A nearby FM radio received the signal. I had to tune both items to an unused area of the commercial FM band.
The kit included a simple rf field strength detector. It consisted of simple discrete parts which I soldered together and hooked up to my VOM.
Such kits are instructive to show what's possible.
Then links you supplied are for superregenerative receivers. As the point is to learn, i would recommend building a standard superheterodyne receiver. Most receivers on the market follow it. You can treat it as a system design and buy an LNA, a Mixer, vco, filters etc, or u cld even design your own subcircuits.

Can you please give me the instructions of the kit, the circuit design, etc.?
What kind of equipment do you have available? How about PCB design, do you have any means to fabricate a PCB, or is this going to be veroboard/breadboard. What about budget for purchasing components? Do you have a signal generator that goes up to 100 MHz for debugging, and a spectrum analyzer? Just trying to find out the limitations of the project. Also how much time do you have? Just 2 months?
