Ok, so i'm not new to lasers but i have never built one and would like to start building my own. i'm looking for a simple build for $25-$30 but with a power out put big enough to burn dark objects.
I would suggest that you do a little research and reading on the
Forum... There are a lot of Tutorials and FAQs and Stickies that
will bring you up to speed about building a Laser.
Then you will see if your request is reasonable...
You can even go to the B/S/T sections of the forum to see what's
for sale as parts or even completed Lasers.
