Handheld 2.4 GHz Spectrum Analyzer via HaD – Miguel writes:

After visiting some web pages about 2.4 GHz ISM band spectrum analyzers based on the CYWM6935 module, I tried to build my own analyzer, but with some improvements. The references I found on the net used the parallel port or a serial link to a host computer. I want the analyzer to be portable, and easy to transport, so I will use a microcontroller and a graphical LCD. I had also some old Nokia phones, so maybe I can use phone plastic box and build in LCD to make my own portable analyzer, but… Does it can be done? Let’s see…

Awesome.

  1. Brilliant!

  2. I love it! I’d thought before that it would be really nice to have a wavebubble in an old phone like this, but it would be a big task to get it all crammed in there.
