Ive got a couple questions, as you can all see im new here so be gentle lol.
ive only taken a few electronics classes through highschool so im pretty new at this stuff.
1. is it possible to create up to a class 3a laser? or to alter a class 1 to be visible? If so is there a site for schematics?
2. I havent played much with EM's but i have been today, Is ther a reason it wont work with a DC- output power supply? it works fine with D-cell batteries, i was basically looking to increase the intensity of the magnet, maybe i went about it all wrong? i guess the noob in me said more power = stronger magnet.
