Do you need IR filter? It depents on how powerful the laser it. My 150mW greeny doesnt have IR filter.. Here are goggles that protects from IR and 532nm Eagle Pair® 190-540nm & 900-1700nm Laser Safety Goggles

Woah thats nice support from Dragonlasers. But the shipping isn't so cheap...

Dragonlasers is good company, and I've heard that the Hulk is very good laser too. Here you can find some videos about it... hulk 200mw laser - YouTube Edit: Didnt realise how old this thread was:wtf:

Have you tried posting this on eBay or on some gaming forum...? :whistle:

This video shows diffrences between focusable laser and fixed focus lasers AZBjbjmv4cs

That's nice. Why did you bump 5 months old thread?

Well... I didnt read the question so well... I was busy. I didnt realize he was using a projector, I thought he used handheld laser.. My bad :o

I suggest you a 445nm blue laser. Maybe PM wannaburn. He has made really powerful lasers... up to 3.5W One of his builds http://laserpointerforums.com/f65/video-added-worlds-most-powerful-handheld-445-3-5w-2-ld-array-63836.html Good luck and remember safety!

That was just a suggestion... I said "maybe use goggles" :na: But you're right, I was busy when I made that post, I didnt read the question so well. Back to OP; Maybe just use low OD-rated goggles so you can see the patterns... I dont mean any OD4+ rated goggles, I mean cheapy goggles (or...

Welcome to the forums... Maybe wear goggles? Edit; Nevermind, I was busy and didnt read the whole question. Keep lights on when using the projector?

Nice build! What's the output...?

You should add some pics :rolleyes:

o-like seems to be down... Edit: Now it works :O http://www.downforeveryoneorjustme.com/www.o-like.com I dont know whats with that site

Welcome to the forums... You should tell something about you @ here And the laser, what color? 2watt green or blue? :p :rolleyes:

I got ~130mw green laser for $25...:na: But still, I dont recommend buying cheapy lasers..

^ ^ :crackup: This isnt laserpointerforums anymore, this is trollingforums lol

Well, 500mW green would be much more visible. But imo 445nm looks cooler (and it would burn better) :beer:

Go with the first one :beer:

Thanks :D Yeah, I hope my laser doesnt output much IR... And my dragonlaser goggles seems to block the laser well Edit: This laser also burns a hole trough CD case... And my goggles dont block IR Any methods how I can check how much Ir it emits? I dont have a LPM

There is no 532nm diodes... But you can buy green laser module (~150mw) from o-like or dealextreme It is hard to build own +200mw green laser.
