Thanks for the research. Amusingly, the lasers arrived TODAY, so cool timing! And thanks for your insights. I haven't done anything with lasers since (long ago) they involved glass tubes and mirrors.

I was (apparently naively) going to power each laser with a pair of AAA batteries, wired directly, which is what it looks like they're doing on the product page. Which ought to fit into sharks.

Then for added fun I was going to wire them up to a 3.3v arduino's digital lines. But it sounds like that'll kill them. Would cycling the power on/off in software reduce the voltage (on average) enough to avoid burning them out?

Perhaps instead I should use a driver, along these lines (http://arduino.cc/en/Tutorial/LEDDriver)?http://arduino.cc/en/Tutorial/... The ws2801 looks great, but it's surface mount, which I haven't tackled yet.
