How to build a burning laser without any soldering, and best of all, in an Altoids tin! This is probably the easiest burning laser one can make, and it doesn’t cost much either.
Parts list: 200mW rated laser module:
Switch and Battery Pack: RadioShack, various electronics stores
Altoids Tin: Be creative
Some rules regarding these lasers: You cannot EVER use this laser indoors without goggles. Looking at the dot up close WILL give you PERMANENT retinal burns. You cannot show this laser to friends if they do not have goggles, no exceptions. Do not point this laser near any other people out side and never annoy people with lasers. If you cannot handle these rules you probably aren’t smart enough to build a laser like this anyway. I’m not trying to be a dick here, laser safety is serious stuff.
Legality: This laser is completely legal to build in the USA as long as you don’t sell it or use it illegally.
Fog was used to bring out the laser beams.
