Hi Laserpointerfourms!
I made this account because I'd like to build a laser.
If I were to put the following together would it work and be able to burn things?

1. LM317 (this one: http://www.amazon.com/10PCS-LM317-L...?ie=UTF8&qid=1435607198&sr=8-3&keywords=LM317

3. 10 ohm resistor (can I use a potenciometer? if so which one do you recommend?)

4. 200mw 808nm Infrared 4.2v-5v laser (from here: http://www.amazon.com/Focusable-Inf...1435606512&sr=8-4&keywords=200+mw+laser+diode)

5. These goggles (http://www.amazon.com/gp/product/B0...m=ATVPDKIKX0DER&pf_rd_r=18TJEJ7ZXEM6NVK3HANG\)

Also what is this: (http://www.amazon.com/LM317-Adjusta...?ie=UTF8&qid=1435607198&sr=8-5&keywords=LM317)
Are there cheaper alternatives to the items I have listed above? I'd like to use amazon to purchase these items.
Please help.
Thanks!

For starters, I would really not recommend a IR laser diode for a first build. Most of us stay very far away from them. they are very dangerous because they seem very dim, so it gives you a fake sense of safeness, and 2 because they don't have a beam, so there's no prettiness like with a visible lasers. I would recommend a LPC-826 or similar red laser diode as they are cheap and can burn quite well too.

Second, if you are messing with higher powered lasers and (especially) burning, you should get certified glasses, like the eagle pair on survival lasers Eagle Pair® 190-400nm & 580-760nm Laser Safety Goggles. Those cheap glasses on amazon/ebay are very unreliable and differ from each other a lot. No two are the same.

Last, as this is your first post, you should make a real intro in the welcome section. Look at this post by a very respected member to see what should be in there. A welcome post will make us trust you more, and give you a overall better reputation on the forums.

Yes he is correct in all mentioned we want to know who you are. And yes go with a 445.450.638.520 and maybe 405nm wavelengths. You can see them safety first ,the eagle glasses are perfect and affordable . Burning stuff well that's ok but there's more to this than just that. You should read up first and read,read ,read. I can't emphasis that enough. There's a lot of things you should know first here you'll find a multitude of info.
Good luck be safe :))

I wonder if someone was reading about the Barber Cut game. I can't think of any other reason a new person would want an invisible burning laser as a first.
