Limited AM radio. Use passive front end Nyquist filter, digital down-converter and low-pass filter to receive the lower part of the AM broadcast band. Got the idea from Oct '09 Circuit Cellar article 'Multi-rate Techniques and CIC Filter'. Success would be anything that worked better than the chunk of geranium and safety pin radio from grade school. | Limited AM radio.

Three ideas so far:
Multiple 8-bit game console sound chip emulator. Generate the sounds of the '80s: C64, NES, Atari, etc. I need to research some of the chips but it looks like there is plenty of info out there. Manuals/schematics:
- Mikes Arcade
- Important Space Invader information
- TI 76489 Audio Chip
- PicoBlaze D/A converter design example
- fpga-synth.net - FPGAs to build/design synthesizers and audio processing engines
