I was kinda active here a year ago or so and I built a few lasers. Now I have began at university and cash is running low so I gotta sell what I have left. This is what I got up for sale: * 1 flexdrive @ 450 mA -never used * 2 flexdrives @ 120 mA -never used All three flexdrives can be set at...

This is the first time I try to sell something here and I hope I do everything right. Please tell me if I am doing something wrong (except the fact that I am selling 2 wonderful lasers that I should keep). The thing is, when I found these forums I started to spend lots of cash on lasers and I...

So, now I have buildt 2 working red lasers @ 450 mA and one "working" Blu-Ray @ 120 mA. ( I have also, lost 1 red 815lpc diode and 1 Blu-Ray 803t diode :p) The thing is, the blu ray is really strange, when removing the lens, there is no dot but more like a line on the wall. With the lens...

:'( :'( :'( I just finished my first build. It was a LOC red diode and a flexdrive. As I turned it on There was a weak red light and nothing more :'( :'( :'( Why??? What did I do wrong? Why does this have to happen? Why!!!!!!

Ok, so I would like to make something cool. I have two hardrives that I have opened and that spins very well. I got several green laser pointers. I got a diffraction grating. I got mirrors. What can I do?. This might seem stupid but I don't really know, and maybe you can't do very much with this...

Is this some kind of joke? http://cgi.ebay.co.uk/blu-ray-405nm-violet-blue-laser-diode-ebays-cheapest_W0QQitemZ270284270916QQcmdZViewItem?hash=item270284270916&_trkparms=39:1|66:2|65:1|240:1318&_trksid=p3286.c0.m14 Would it be possible to put in 3 "diodes" in one diode? Sounds pretty weird.

Ok, I have been trying to find the answer to this but I failed. O please dear fellas, give me some guidance :D An long open can diode I have seen, but can u use it just like a closed can diode? From where do you get open can diodes? Blu-rays?

Ok, so I got this diode from a laser printer that I will try to make some kind of laser with. I don't know if it will work very well but I will try to make it work. I have a pretty limited budget so I want to try to use what I already have. especially since I will probably break the first...

Hi all! I'm a 18 year old guy from Sweden who loves computer, physics, chemistry and especially LASERS ;D THe only problem is that I am a huge Newbie but I am currently reading a lot to get more understanding about lasers and how I can be able to build my own powerful laser. RIght now I am...

Hi everyone! I am a complete noob on the area but I am very interested in lasers and after having read about and watched several DIY projects with laser pointers I now intend to do one myself. Now, I got thinking how I would get all the stuff I need. You see, I live in Sweden and there ain't...
