You might be able to turn it into a burning laser, at the cost of the laser's lifetime. It might get powerful enough to burn things, but it wouldn't last very long.
umm, that sounds like a waste of time then, what would be the easiest and cheapest way to make one? do you know what i would need to make one? i already have a minimag
You could modify it into an IR burner, but it would be harder than it looks.
DON'T do the minimag mod. You will get a laser that lasts 5 seconds if you try that mod.
