i have a budget of up to 200$, but i would prefer to keep it more around 50-100$. I already have safety goggle too.

Never ever made a laser pointer before, and also have no idea how it works. I couldnt find anything that was helpful for a complete beginner. I have no idea how drivers work or anything complicated, and am looking to make a simple 20-150mw green laser for relatively cheap. Any help would be much...
