Hi!
I'm doing some DIY projects strictly for home use with lasers. I'm planning to make a good spirograph laser "show" and perhaps a galvo scanner at some point in the future, and perhaps a line scanner.
Since I'm basically a noob on lasers, apart from having a few of your typical dollar store pointers, I don't know much about how powerful lasers I need for a good effect. I was planning to start with a typical 5 mW 650 nm red laser such as this one: Ebay Mitsubishi laser
And later upgraded with green:
Green
Would this be safe to use without safety goggles? I'm aware that lasers on ebay could be over-specced and could potentially be a hazard. I don't want it to pose any danger at all for people not wearing goggles, and there won't be any way to stare directly into the laser, will be projected on white ceiling and walls.
Would also like an option for blue laser, but seems to be harder to find low powered 5mW blue laser modules, so I may assume blue is not as safe to use?
Tried to search around, but didn't really find much which applied to my application, but I did find that <3mW was max safe for general pointers.
