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:

|
|
|
|
|
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.

|
|
|
|
|
|
Game of life analyzer. Run game of life for many generations while
|
|
|
|
|
saving/encoding previous states of the game array to look for repeated
|
|
|
|
|
and other patterns. VGA game output would be fun too. Some fun life/CA

1/27/10 - Patched together some Pong code (game not the professor) on
|
|
|
|
|
the Spartan 3E dev board to learn VGA interface. Pong code lacks
|
|
|
|
|
sounds - might as well give that a try. 8/25/10 - Run ISE simulator
|
|
|
|
|
under Win 7 - set webservices to startup automatically
