So, I just won a "20 mW" green DPSS laser module on ebay for $2.85. There is only one problem: I don't have a use for it. And me, have zero inspiration, thought I would ask you what to do with it. Sure, I could build it into a pen, but that's boring. I need wild ideas!

Salvage a diode and a dichro from a blu-ray sled and make a low power yellow laser :)

Yeah update us on the output, check if it can burn things when focused, that way well know if its one of those rediculously underlisted ones

That's a pretty good price for a module that will probably be overspec!
Most of them are a set focus though. Unless you break the epoxy free!

Well, the rated max current is <280mA, so that would be a 200mW diode, and so it would be with 20% efficiency a 40mW output. Fairly decent for 3 bucks!
