After reading this, and then this, I started thinking of how easy it would be to make a burning laser. I went to Radioshack, got some components, and started thinking. One thing that Stephanie's laser didn't have is a potentiometer, to control the power of the laser. Well, I ended up getting 12 assorted pots at Radioshack, but didn't know what one to use. I want decent control, too. What size (in ohms or k-ohms) do you think I need? I'm spotty in my electronics knowledge. PS- The size in ohms on the pot is the pot's range, right? If it says 100k, it means that it will resist from 0 to 100 kilo ohms, right?Also, in the shematic below, I don't know if the pot is connected correctly, post a comment if it's wrong.
