My Girlfriend bought a bunch of crap at an auction (3 trips with my Suburban so full I could only use the driver side mirror.) In one of the many boxes was a case of old keychain laser pointers, most of the batteries were ruined and the housings are pretty nasty but the guts (laser diode and switch) still work on all but the very worst.
Now, what do I do with them?
There are probably tons of cool projects I could do with one or two but I have like 50. I really think I'll get burnt out doing a bunch of little projects, so I wanna do something big with as many as I can.
Please give me suggestions of what I can do with these. They are just the regular 4.5v laser pointer key chains that come with different tips. I know they aren't powerful enough to burn stuff or anything like that and I do know how to solder and use a multimeter and other basic skills required to work with electronics.
Reasonable Ideas are fine I'm not expecting detailed instructions, just general ideas like, Movie-Museum-security style laser grid around stuff in the house, I'd need a fog machine too, or an array pointed at my front door from the trees in front of the house that move randomly like movie swat team snipers.
