ELM – AVR based radio spectrum monitor

Chan writes –

This is an experimental work to monitor a spectrum pattern in radio band, and is a continuous project from Audio Spectrum Monitor. To analyze the spectrum of an input signal, I chose an Atmel AVR microcontroller that used in the Audio Spectrum Monitor to process FFT. When think it easy, it can be thought that sample an input RF signal directly and analyze it will do.

  1. Good to see your work here, Elm-Chan!

    Blinking LEDs are always great but it’s nice to see more advanced electronics projects covered here in Make blog. This (albeit old) one and the 4-bit processor in one day — I wish every day was this rich :)
