I'm thinking about buying a blue 1W Spartan Laser, and It worries me with safety precautions. I wouldn't want my brother getting a hold of it and pointing it at someone's skin, or worse, their eye. I put all my lasers in my gun safe, but I keep that locked and the ammunition stored separately so even if my brother got into that, he wouldn't have ammo for the guns. But, to the point, what would a 1W Blue laser do to skin and eyes?
You could use 3/4 drywall screws.The hole they make can be filled with tooth paste.You could mount them to the wall.
There are cheaper detectors with double stick tape that comes with it. I would try DS tape. As to the paint, it depends on the quality, age, finish.. of the paint.
Even he, to whom most things that most people would think were pretty smart were pretty dumb, thought it was pretty smart. Douglas Adams, The Salmon of Doubt, p. 205There are things that act, such as your mind; and things that are acted upon, such as these words. Your mind acts upon these words. We live in a dimension of faith. (Not all science is a joke.) On one level there is Matter and Movement. Faith is not-perfect-knowledge. Faith presupposes a dimension of freedom. Faith is movement or action. You act. Truth is the foundation of your very existence. Truth is knowledge of things as they are. Faith is movement. Faith is action. You have knowledge, but it's not complete: you don't know the future. (You can't even remember much of the past for that matter.) Unless you have all-knowledge, then it's Changeless. Yet having all-knowledge doesn't change what faith is. It's the same yesterday, today, and forever. Movement in the dimension of the Changeless is what it is. Freedom in the Changeless is what it is. All contradictions in the Changeless are what they are. These are words. They may refer to something if you have the faith to bring to pass the meaning, even the true meaning thereof. Amen. The people who didn't have the faith or action to read these words don't have the knowledge of their existence. You're doing what you're doing because you did what you did.
