yeah don't worry. i know they are reputable now. so it doesn't matter anymore. i only knew sanwu and o-like before today. (and my first laser came from warnlasers back in 2013)

yeah like i said. i'm learning. and thanks for the tip. i'll keep that in mind. i'll deffinatly buy a dtr for when i move up to a 1.8 or 2w diode

-well i'm sorry about the double posting. it's something i am not aware off. i don't go on forums alot. but i guess by now that is pretty obvious. i'll learn though. -i had a question in 2013 and made an account.. i got or found the help i needed. and that's that. it's only now. this...

it's not that it wasn't pretty. but i don't know anything in this world. no person. no company. so if someone gives me a link that's not ebay or amazon or something. i am immediatly on guard. if it then at first glance looks like the standard scam websites. you guys know what i am...

hey guys. quik question here. i am building a laser engraver and it's basicly my first time playing around with home made lasers. and i have a question tldr. i made my own laser driver. and when i adjust the current i see a weird effect and i don't know what it means. also i think i may...

i do know what i am looking for now. and i have given up on local suppliers. i guess there are non. so either alieexpress. amazon or ebay. and then a (do i even need glass? for less then 500mw) focussable lens, housing for a 5.6mm diode. i am currently just searching for that. and i am...

to clarify why 15 dollars is such a big deal in this case. (because 15 dollars isn't much i agree.) but the whole machine that i am building atm has not cost me more then 10 bucks.) so 15 dollars for just a laser housing is a pretty bad investment i had old dvd drives. i already have...

basicly if i have to spend 15 bucks on a copper laser housing. i'd better have a much stronger diode to put in there then a simple 150-300mw red laser diode from a dvd burner. (lets say average 200mw)

yeah no thanks. everything about that website smells like a scam. the cheap layout. the change in background from the homepage to one of the product pages. (makes it seem like a completely new site) but most of all. if you ad something to cart you immediatly end up on paypal. with...

this is what i am making

i guess here in the netherlands i am just out of luck. i can choose from a 5mw laser. like this https://www.kiwi-electronics.nl/laser-diode-5mw-650nm-red?search=laser&description=true&sort=p.price&order=ASC from inside the netherlands with 1 day shipping. i cannot find any lose laser...

something like an aixiz module. that i can press one of these into like this https://www.amazon.com/AixiZ-30mm-laser-module-blanks/dp/B004LZHA0I that i can press the diode in for heatsinking. and that i can screw a lens into. i did just find this though...

and if i am going to buy that 500mw red laser i could also just use my 1w blue laser module. (not enoegh heatsink though) it's from the O-like laser pointer though. the waterproof one of 50 bucks. so i don't want to sacrifice that. they gave me no duty cycle. if i have enoegh heatsink...

so. i am building myself a laser engraver from 2 old dvd drives. made my own driver. 3d printer the frame. excetra. anyway now i have gotten to the laser module part. i cannot find anything about making your own laser module. prefferably using the lenses from the dvd drives. every single...

oh forgot to mention. i have about a 1 to 1.5 mm gap when it's focussed in a beam. and on a side note. i know this is quite a necromance. i blame the search function.

mine doesn't go all the way down to get a straight beam either. it's the way it's supposed to be. it requires some force to get that focusing ring to turn anyway so once focussed it will stay focussed. but if you really want to. see images. the red arrow is a collomating lens. on...

why do you guys keep assuming i am some 14 year old unresponsible kid. stop trying to protect me. i can do that myself

a co2 laser would be nice as one of those square modules that i can mount to one of my 3d printers. but that is not what i am looking for. i am looking for a laser pointer with that kind of power.

i mean he (encap) didn't even watch the video it seems. the freaking thing cuts a box cutter blade. and he says i'm better off with a single 4w diode or whatever. no i'm not because it cannot cut metal and stop telling me to start somewhere simpler. if i want something simpler i will buy...

-_- why even respond if that's what you have to say. point me to a single diode that can cut a box cutter blade like it does in the end of the video. what? there is none? guess i have to combine a couple then.
