Hey, I'm a sophomore in college and I'm working on a DIY blue laser (440nm I believe), sitting on a breadboard for now. Since it's relatively high powered, I'm going to want to run it at around 1A, I'll need about 9V for the driver I'm using, etc. cookie cutter blue. The driver will be a very...

I apologize if this has been covered anywhere. I searched, researched, and looked through all the first page threads and couldn't find anything similar, and now i'm stuck. I just purchased the popular A 140 445nm diode, and my driver is having issues. Before deciding on a permanent host for it...

I think I have enough money to buy the stuff for a tesla coil. With that said, a while ago I took time to try and read up on how a tesla coil works, and how you go about creating one. Now since the only real electronics education I've gotten (until next year when I'm taking physics) is from...

Well I just finished up my Junior year of high school and really have to start deciding which colleges I want to apply to. My main interests are engineering, physics, a little computer science, and just math in general. Also, of course lasers. Dealing with light. Would that be considered...

Hey guys, not sure if any of you remember me since i've been here last (on the old site, just logged on today to find that the site changed). I sorta drifted in and then out of lasers through my early years of high school, gonna be a senior next year. I never really LOST my interest, just...

Hey all, I'm coming back from a break of not doing any DIY or building. It's only been a couple of months, and although I learned a lot, I never knew enough to really say I knew A LOT about lasers. I've just had too much school and personal life issues lately. But I have 2 orders for lasers...

The last week and a half I have been (I live very close to Houston) in Colorado. Yes, I took my lasers, and yes, I had a great opportunity to use them! My dad And I went mountain climbing, and we decided to climb one mountain during the night to see the sunrise. Unfortunately, and at the same...

I'm looking for some aixiz modules, empty or not. Also, if anybody has some 5 mW diodes they don't want, I could take them off your hands. I'm just looking for cheap supplies, so I'd rather not have any 5 mW reds pre-installed, as I'd have to pay for labor, too:P I'm in Texas. I don't really...

Today I got bored. I have another 5 mW green laser in the mail, so I thought I'd look at the insides of my Galileo-5. It started like this: skipping to the end first...this is what the tube looks like completely empty. Looks like it could be easy to mod. There's a battery stop any everything...

Today I revived my old dead blu-ray box and slapped a PHR in it. It's at about 86mA, but I don't know the actual output because I don't have a LPM. However, I started trying to light a match. Try as I might, I couldn't get the red match head to light. Then I let the dot go on the white on the...

AH our DVD player ALMOST broke today. The disk spins around and makes a weird noise,but my parents decided it still works :( When it breaks, I'll have myself a free 5 mW red laser! I think. It's only a reader, so it should only be low powered right?

Hey, I'm a Junior in high school, and its time for me to start looking for a college. But before I can even really choose a college, I need to think about what I want to do for a job... so does anybody know of any laser related or electrical engineering jobs off the top of their head? I am also...

So many members are now making their own micro drivers. Hell, I even made my own driver (not on a chip), but it was somebody else's design. I haven't designed my own cause I don't know what all those components do unless somebody explains it to me first. I sort of understand the LM317, but not...

Many times small flashlights are used for hosts, but does anybody ever use cheap ledlights or cheap ebaysers to gut and put nice blu-rays in? In my opinion, gutting out cheap lasers may be a nicer look than a flashlight. It will cost a little more, but with the new tiny drivers coming out, as...

I am in need of some AixiZ modules (blank). I just looked all over their site, and I can't seem to find a page to order just blank modules! Do I need to email them to be able to order these or does somebody know the page to order blank AixiZ modules?? Thanks in advance Alex

I know AixiZ are always going to have loose lenses because they aren't premium quality, but does anybody know if there's a way to maybe make the lenses fit a little tighter?

A while ago, I remember that people were getting bad diodes from stonetek. is that bad batch "over" now? or are people still getting some bad diodes from him?

Well I finally finished my DIY open can red laser. Its not at full power yet because my batts are not providing enough voltage, but its still BRIGHT. and yes, I have glasses for it! so far I've lit several matches unsharpied (red head) and I've popped 2 balloons from quite a distance. It can...

Question about LM317's I have recently been having ALOT of trouble with my DIY. I think its the solder, cause everything else has been replaced or tested. However, I am going to replace the LM317 YET AGAIN to make sure thats not the problem. I want to make a completely solderless circuit. But...

Well after much thought of easy ways I could ground myself, I have thought of one good way. my work place is really close to a window, so I thought maybe if I stuck a metal stake in the ground, attached wire to it, and threaded it through the window. Then I would tie it to my wrist. would that...
