Hi everybody,
I'm from Guadalajara, México, I was reading the forums the past weeks and I just decide to register, I learned so much (and get in love with the idea of getting an 405nm laser, I alredy play with a lot of leds of that wavelength and the ligth is lovely).
I like to build things and recently I get attracted by electronic and I get an Raspberry Pi, searching for proyects to do I found an instructable for a 3D printer using the pieces that moves the reading unit, from there I fount a similar project to do an laser engraver with a multifuncional motors and from there didn't took long to be attracted for lasers.
Time ago I was interest on lasers but with 15 years old and no money I couldn't do much, I bougth some cheap lasers (reds that works on AG-13 batteries) and wonder getting a green one that I saw once.
Now I'm 25 years old and have a job so now I can get money to spend on this plus the basic electronic skills I got. My idea is still to build my own 3d printer, but before I want to try the engraver machine (2 axis, so it should be more simple), but before that I need to understand the ways a laser is build and built a few (for practice and fun), yeah, a little big list to do.
I alredy own a 532nm "100mw" (from what I was reading here now I'm pretty sure it's not a 100mw) that bleed a lot of IR (alredy tested whit an IR camera) and 2 of the little reds "5mw", Im not sure their potence nor the wavelength.
I'm also harvested some leds from a dvd writers, I alredy burned 2 and store the others because I'm not own a safety glasses yet (when I saw the ampunt of ligth comming from the second I understand the need of glasses (don't worry, the diode had no lens so just spread the ligth, only hit a wall and non reflective objects)) but I'm currently looking for buying ones, probably from survival lasers, thats one of the main reason I found this forum.
I think I may wrote to much for an introduction, I want to add that I really like the way this community be, the forums I usually visit are more serious (mostly technical about software development) or with few recurrent users, I hope I can be here for a long time. :bumpit:

PS. English is my second language and I'm doing my best to learn it, I'm writing this without a traslator, sorry if something is wrong and if is possible I wil appreciate if you can tell me if I wrote something wrong (if it's no too off-topic), thanks.

Hello D4rB, let me be the first to say welcome to LPF. I don't think we have any other members in Mexico right now, you might be the only one.

Welcome to LPF!

So....405nm huh? That's a pretty cool & weird wavelength at the same time, at least to me. So many cool things to try with 405 :)

Thank you, I didn't expect comments so quickly, is great to see the community is very active :D

Unfortunaly I'm not really surprised, a lot of people here are not very interested on this kind of things (of how things work in general, electronic, bluidings, etc, geeky stuff they said), I'll try to attract some other than migth be interested on building lasers.

yeah, the first time I read about it I was in shock, I never thing that could exist, since then I want to order one but first I need to get a glasses and learn a little more about handlind mid power lasers and how looks the real power (I don't think the 532nm "100mW" that I already own is a good reference).

405nm is dangerous, extra caution is required, it is barely visible. The visible spectrum ends at about 400nm. I have one I built that is 590mW and the beam is visible only in dim light and then not very bright and yet it will burn anything I point it at.

Yes, indeed, that's why I'm not ordening one yet, first I want to familiarize with >5mW lasers before getting one, maybe if a I find a >5mW I'll buy it. :)
