Hey guys, OP here: I guess this discussion has grown beyond my original question, and I'm glad for all the great information. Here's the plans for that homemade "laser show", in case anyone's interested. A nice PDF. Some pictures. I'll post some pics if there's an appropriate place for that...

Thx Benm that's sorta what I was looking for!

Thanks guys. That axizis unit looks great!

Well basically that's what I'm wondering. Specular reflections: How bad would it really be (I'm not planning on being any less safe here, just wondering) if oops the beam hit the cieling fan brass and reflected into my eyes for a split second, any permanent damage?

So a 50mW would be relatively safe? How long could that o-Like 50mW Green run, as far as heat goes? Would it need a heat sink to run continuously?

So I'm buying my first laser to make a fun light display synced to music. ( Just mount a mirror on a small speaker and aim the laser at the ceiling ) I'm wondering which of these is safer / brighter, a: 20mW Green DPSS laser module or a 140-150mW 650nm Laser diode module? Both from Sunclan...
