A very simple hardware project to broadcast your voice or other sound input on an FM station of your choosing. Uses the PIC 16F688 as the main microcontroller. A Codeproject article located at http://www.codeproject.com/KB/system/fmbomb.aspx talks about the creation of the project.
The FMBomb can be powered with 3 to 5 volts. A 30 inch piece of wire attached to the transmitter RF pin makes a decent antenna with pretty good range.
Part numbers, if listed, are Sparkfun SKUs.
