I have never built  a laser before, but I have built my share of small circuits, and I want to build a burning laser. I only have about 50 dollars to  spare. I have used a focused magnify glass to burn leaves and would like the same effect if at all possible. Please tell me what parts I need and in how to ensemble them. *if I have to spend more I will, but only if I have to

Well you need to get yourself a DVD-RW drive to extract a nice and powerfull diode.Then look up the ddl driver in the experiments and modifications section.I think this will be your cheapest bet.An open can diode from a 20x burner should be good for 300mW, but even that is not enough to be able to burn like a big magnifying glass on a sunny day.

Welcome to the forums lasernoob80,

Theres a lot of good information to read up on here.
With you having electronics experience, you should be able to build something nice for around $50. to $75.
