Yea, the 2 week thing is a little concerning. But hey, we're geniuses here right?
Having thought about it more, I am keen on an "echo location" kit. Imagine some electronics which generates an ultra-sonic noise (40kHz? 60kHz?), then receives it (via normal microphone?), and then frequency shifts the sound back into human hearing range, and uses ear-buds to display it to you. If the frequency shift is done correctly, you could even pre-process the sound data to help "amplify" the difference that close object bounces creates in the sound. This leaves the real data processing to the brain, of course - it's still going to just be a bunch of sounds, not a map of what's around you. But I actually think this could be way superior - who knows what kind of patterns your brain could pull out of the sound if you just wore the electronics for a week?
I have no idea how complicated the frequency shift math might be, but I think the electronics for this should be doable using Arduino-class hardware?
Anyway, it's a fairly major project, but I'm adding it to my "eventually" list.
