OK, this is scary...

jonsinger is looking for broken Blu-Ray devices. He'll take 'run over by a car' broken!

Why do I find this scary? Maybe it's the thought of 'what is Singer going to do with lots of high-frequency visible light LED lasers?'?

I bet he's actually doing something like following the instructions in that article I linked to. Using something like a resistor to regulate current.

You really must use a constant-current supply to run a laser diode. If you don't, you'll fry it. If you use the proper supply, it should run for thousands of hours.

Actually, from his write-up, he's finding them to be very sensitive in the circuit construction phase - he's lost them both to construction problems/errors.
