Well matches/black paper / plastic etc nothing happens. But that DVD used to work before i took it apart

Im sure its not the IR :) The other diode in the DVD was way to small compared to this one. I tried to place a match in front of it but nothing :) So ill just buy a new LD or ill try to harvest it from another DVD :) Edit: It dsnt even burn a toilet paper :D

The diode is in a heatsink. So i dont think heat is a problem. I never tried it before so the this is the first time i do test it. :S

So i went to the shop and took 4x 10Ohm and 4x 5.3Ohm. So i used both 2x 10 Ohm and 1x 5 Ohm resistor with a 7.5V battery. And both gave me the same result :/ A small red dot on the diode but no reflection aywhere . What is wrong ? This is how i connected them .

I placed a heatsink on the Lm317. Anw ill try it and will reply in about 16 hrs :) Thank you

Well i used only one 10 Ohm res. I had 2 But one didnt work :/ So im going tomorrow to the shop to get some others :) Also i have some batteries as i wrote before :) Which one should i use ? I mean the V that i need ?

I cant see it in the wall . Only if i take it really close to the wall i see a divided beam. (/ /) Im sure its not the IR one :) i used a spray over it :D and nothing . Even flour didnt do anything . Edit : I have 8-10 26650 batteries . Then only problem is that i have only 4 of them fully...

So i tried some exp :P I hooked the LM317 Adj and Vout with a resistor 10 Ohm . Than the + of the LD with Adj . The negative with - of LD and Vin with + of battery. And i got a small beam . Whats wrong ? The current ?

HI :) Thank you for the response . I have the laser diode / host / heatsink / And the parts to build the Lm317 except the 100Ohm variable resistor :) No i dont have a LPM unfortunately :( But i want to try out the diode first than put it in the host :) And wannaburnstuff i would be pleased...

Hi again guys . Im coming here once again . I bought the LM317 and already have the 2x 10ohm res / cap / diode / but im not sure if i need that 100ohm variable resistor or just a 100 ohm would do the job. Also the best current to start the test for the diode would be ? thank you

Well i digged more and found out this driver would do the jobLaser Diode Driver Board 20 300mA TTL Control Adjustable Current | eBay Thank you atheist for that section. Also what would be the best current to drive it or i should test it to see how far can it go ? :)

Hi guys ! I finished my first laser . A 10mW green one around 13$. But i know that its not powerful. So i found a DVD burner around the house and i opened it. There are 2 diodes and took out the biggest one. http://i.snag.gy/tDNRs.jpg http://i.snag.gy/F3txB.jpg http://i.snag.gy/uivED.jpg...

Well ordered the module and that LPC. Later ill order the host too. Thank you guys and Grainde + rep !

Well ill get that LPC826 as a first build. DIY 12 40mm 5 6mm Laser Diode Module Housing with Mutiwavelength Lens | eBay This is the cheapest i could find.The aixiz is 13$ + shipping. And im getting the JAD kit from mohad with C6 . It has included the Heatsing and linear driver + soldered...

Well thank you both for the reply. I think i will buy that C6 host from Mohrenberg for 20$. Now i just need the module. Any sugg from ebay ?
