The project illustrates how a very old and vintage radio was made to connect with a TDA7330B RDS demodulator along with an ATtiny2313 microcontroller making it an RDS decoder.
The project uses a purely electronic device to create a hardware keylogger with a wireless modification to avoid a physical access to the keylogger while retrieving the captured data.
The project aims to create an interesting double-sideband (DSB) radiotelephone transmitter that is powered by the operator’s voice due to the instantaneous energy produced.
The possibility of producing FM crystal radio is shown in this project which can produce a sound with high fidelity that is as good as or better than more expensive AM radios when connected as a receiver.
