Re: Green laser modules HUGE BLOWOUT SALE L@@K I got a chance to measure the current my module is drawing, using a 3.3V power source it is drawing 700mA +/- 10mA. I also was playing with some lenses today. I passed the light through a 12mm diameter plano convex lens at about 10 feet from the...

Re: Green laser modules HUGE BLOWOUT SALE L@@K in my video the matches I used had red tips, it takes a few seconds for them to light up. After I made the vid I drew black dots on a few and they lit up much quicker.

Re: Green laser modules HUGE BLOWOUT SALE L@@K I made this video real quick so everyone can see what we have been getting in the mail. Unfortunately I asked NexBox to send the module without waiting for the power test, I didn't realize the difference would have only been a day...if...

Re: Green laser modules HUGE BLOWOUT SALE L@@K Well... My module should be in the mail when I get home. I need to know how much voltage to feed it. I know 3 volts, but can I not go over that, would it be a bad idea to hook it up to two AA? How about 3?

Most definitely! I ordered on from NexBox, hopefully it is here this week :)

I built a few lasers out of legos, check them out in the media section look for red Lego lab laser

It is a PHR, the driver is very a very rough made with the LM317, I say rough because it was the first driver I built, I had never soldered before, so everything is twisted together with electrical tape inside the legos, The potentiometer is a 25 ohm rheostat from radioshack. Originally the...

Like this? :D YouTube - Blue Lego Laser I just posted this, not sure if the link works yet.

Im glad you guys like it, here is a link to a thread I just posted over in multimedia. There is a link to a video of the laser that I posted on youtube. http://laserpointerforums.com/f48/red-lego-lab-laser-pics-vid-49732.html

This is my first build :) The diode is from an 8x burner, more info on the build can be found in the "Red Lasers" Section of the forum. I figured I should post the media in this section Here is a short video I made: YouTube - Red Lego Lab Laser

Hey guys, I have just completed my first successful build. While waiting for diodes to arrive in the mail, I got impatient and figured it would be a good idea to practice extracting diodes from sleds, and practice soldering while I wait for them to come. I had some spare dvd drives, and a...

I didnt see LM317 when I scanned my post, that is the driver I built

OK. I am sorry if this is covered somewhere else but I have looked and looked and cant find an answer anywhere. Maybe my search skills suck or something. I am waiting for some high powered diodes to arrive in the mail, but I had some DVD and DVD recorder drives that were lying around. So I...

the second large mirror from the right is actually a 50/50 beam splitter I came across.

Well the round mirrors happened to fit nicely in a 4 by 4 open section of lego blocks, to keep them secure i just used a little piece of rubberized padding. As for the larger mirrors I just built around them.

I was at costco today and I picked this up thinking that these might make a good host. I am still very new so I have pretty much have no idea about anything, but seeing that the two were $15 I figured maybe it might be a good deal worth mentioning here. TechLite: Tactical LED: 2x pack, $20...

here is a picture of the mirrors I used in the video

Yeah, I sat there and kept trying to get it to light, but no go. I was shocked when I saw some smoke rise when I put the focal point of the light on the match head.

Yeah its 5mW. Me and my brother had gotten 4 or 5 similar ones but this one definetly stands out in terms of visibility. Just for the heck of it I tried using it to light a match with it through an external lense, no go on lighting, however I was suprised to see the match start to smoke :)
