Some of these USB sensors look brilliant.

I had been curious as to whether such a kit existed, something that would allow you to hook up several peripherals and build a science/analysis/detection system... I can imagine a wide variety of options. Related, I was looking at the buglabs stuff [http://www.buglabs.net/] because there some of the talk surrounding the pluggable modules was rather interesting; but I'd rather built it myself.

Power might be a problem, but it looks very hackable, I'll defiantly be poking around that site with the intention to buy. Very cool.
