What can you do with a crappy laser? Like the ones you get at gas stations for $4. Anything? Lol. Maybe, stronger to melt stuff, or even a change of colour? :P.

Cuz aren't the good ones like $130 :P?



Thanks,
Onn.

You can play with your cat (or some dogs) with it.

You can shine it on the ceiling and say, "Ooooooooo."

You can pretend it is a powerful death ray and shoot your friends or little brother

You cannot potmod it to be a burning beast. Those cost like, a lot of money ;)

Peace,

P.S. If you can figure out how to easily change a lasers wavelength (color) there is a Nobel Prize waiting for you.
 
If you mean the 1mw reds then very little.
You won't be able to change the colour but you might be able to get a bit more power by modding the driver circuit but that will get a little more brightness but certainly not enough to melt anything. Although if they are very cheap then they probably have a really simple setup with no veriable resistors or any other easy adjustment so modding would require changing components.
If you want to give it a go then you can crack one open and post pictures of the driver, just don't expect any major changes.

Sadly there is a reason why the $130 ones cost that much ;)

Can't wait for someone to make an adjustable frequency multiplier crystal, would be sweet! :D
 
If you have reptiles, they love it.

I was using a cheap red laser to indicate the food to my picky geckos so that they would chase the light and eat their dinner. It worked pretty well, until the crappy laser broke after a couple minutes of use.
 
you can pretend it's a powerful IR burner, and that not really bright red dot is lots and lots of IR!
I had one of those 1mW red's sitting on my desk and my little sister picked it up and asked me if it burns and I told her it's a powerful burning laser that cuts metal, but most of the light is invisible.
 
LOL mikeeey, I once convinced my friends that my DX200 was a military grade laser for which I could spend years in a federal prison for.
 
nothing false about that statement ,you most certainly could go to state or federal depending on what you pointed it at :(
 
Well, I was mostly trying to emphasise the point that it was military grade, IE extremely banished from citizens.

Sadly though, you are right.

.......but that you would be willing to sell it to them for $200. bucks ;)

Well actually, if you pointed it at someone you deserve to be in a fed prison

Yea I dunno, I point my lasers at people plenty of time. I don't think I deserve prison for that. :-/
 
I have a hunch, that Onn is now Off. ;D

Switch, I think John meant in public, not in private. But it's only a crime if you get caught. :P
 
if your burning flash paper ok if your popping balloons ok even if your frying bugs ok --but you go pointing that puppy at a chp airplane you had better purchase some soap on the rope for your prison stay :'(
