Here is a 2.4GHz spectrum analyzer Miguel built into a Nokia 3410 case.
His design is based on the CYWM6935 2.4 GHz radio module. It’s controlled by the ATMega8 microcontroller. This project scans the 2.4 GHz range and displays the bands currently used on an LCD.
The really cool thing about this project is that the whole thing fits inside the original mobile phone case, and makes use of the original phone’s LCD and battery. Check out the pic of a fully assembled prototype below.
Spectrum analyzer is on the left, the original phone is on the right. Miguel was kind enough to provide the schematics and source code for his project.
