[islandlabs] Tonights Meeting

I saw that today's planetarium outing was cancelled.
I assume that means that the StonyBrook meeting is back on (and hopefully Jonathan confirms that) but I can't make it today, so have fun everyone.
Here's something to think about though:
Joe's intervalometer design would be a good entry.
FYI: the worlds most useless device is also 555 based.
Any other ideas?
If we want to get super-aggressive:
It'd be super-cool to build a primitive (4-bit?) CPU from scratch.
The 555 would be the sytem clock. We'd need it to drive a counter. (the program counter)
Then there would have to be a memory bus...
Is this possible for us? I don't know. Very very cool though.
Interview with the inventor of the 555.
