UPDATE! Newer eBay laser pointers are now being made even cheaper. This is going to make finding a green laser pointer with a current regulating driver more and more difficult. Now they are just flat packaged 808nm pump diodes with just resistors for limiting the power and cannot be used for this. I may cover this in a video talking about the degeneration of the cheap green laser pointer quality over the last 10 years. Another note if you chose to use the 5.6 and 3.8mm modules in a pointer you MUST electrically isolate the laser diode host from the case. This is because those red DVD/CD laser diodes are case negative. IE wrap the piece with the laser diode in it with tape/plastic or you may short out batteries when placing them into your finished pointer.
Hands down best vid ever on this
What a brilliant young man. I see this video is 4 years old. By now he is likely a research scientist for NASA.
My grandfather and you guys make soldering look so easy. I'm 55 years old and watched my grandfather thousands of times. I still can't do it.
Are you using Flux? I struggled for years thinking Flux was optional, night and day difference.
It's so easy to 😢 apply too much heat, you have to 😮be fast and decisive
Just lucky I came across this video. Great indepth explanation. The different types of diode and viewing them under magnification was awesome! So much more info than any other dvd laser project. Well done! (And I haven't finished viewing it all yet)
Glad you enjoyed the video and found what you where looking for!
@@Zenodilodon I don't know how I have not found your channel sooner is bizarre because almost half of my viewing is electronic repurposing videos. I hope you are still at it! I hope you are having a career in electrical engineering.
OMG this is the BEST and most complete video I've watched about this topic, thanks a lot man I appreciate it so much
That was my mission! I hope it helps you on your way to getting laser projects created successfully.
Thanks for getting into the micro details. Not many do that, and that is what I want to see the most.
It is wonderful seeing those laser diodes under such powerful magnification, really in-depth of the circuitry and experiments are done so nicely with explaination, Fantastic video man.👍🏻👍🏻
Man, thanks for your video. I was thinking about to build a powerful laser from scrap dvd's, when i was 14 or maybe a bit older. I had poor soldering skills and had very little knowledge about how lasers works, so i burned a couple of them and stopped doing this. Now am good enough to make a try and build a laser. Your video is very informative.
This is a great video to give people a good chance of getting these plentiful lasers going without popping too many! I myself have taken plenty of these apart and I was sure I was doing something wrong because every time I tried opening the cases, however carefully, I always ended up with `crunching` sounds! My interest was in the IR diode at the time, I was using them to send FM modulated video down a multi-mode fiber optic. The open case diodes were best for my application as I could couple plenty of energy into the fiber by bringing it real close to the laser without the need for any lenses. I can say with all honesty that this is one of the best `laser` channels on TH-cam! Thanks for putting all this great content online. Chris, UK.
This is the video ppl have been needing for the past 12 years
You're not kidding at all, I was watching it in production and thought the same thing practically.
Quality video that i wish i had seen before i burned 4 of my first laser diodes and then had to wait a month to get new ones. Keep up the great job !
I love bare and basic videos, they are so educational
an hour of pure entertainment, I love it :)
Greetings from VEN.
Subscribed in first 10 seconds. Based on video title and demeanor. To the point
I hope you enjoy and learn some stuff. Welcome to an odd and BS free channel.
I've been disassembling laser sleds or whatever you want to call them for years. Was almost no luck I found that files a small files are your best way to get those things out because you got to be careful with them The shock of a cutter can mess them up. Let me just tell you this video I wish I'd seen the years ago she'd made it years ago It's the greatest video I've ever seen as far as lasers go and building your own This is Thank you so much. I think I'm going to start doing this again after watching your video I have a whole new understanding of these things. Thank you so so much I really mean that. Thank you !
Thanks for the feedback, I'm glad that the video was useful and that it has inspired you to do more with lasers!
the video is long but it totally worth it 😀 this is the best video for those who want to make a laser pointer for the first time 👍🔥💯 keep making such good videos
Thanks! I certainly will continue, I have lot's to share and I am always learning too :P
Oh, thank god you have one of those weird form factor diodes! 56:30. ^^
And thank you for the very comprehensive video!
Nice job. Good instructions. I really appreciate your efforts to help and I hope you can make a big laser diode in the next...😱 A millions Thank friend.
you're awesome, man! finally someone who does electronics i can easily understand, even tho my english sucks.
I am very glad it was helpful! I wanted to answer and an all questions on this topic many people just getting into lasers might have and give them the best knowledge I can to help support their dreams!
Very informative. Thank you.
Wow. You're waay better than styropyro. You know way more and you taught me way more. Just looking forward to you building a HeNe laser pointer haha.
Oh I would love to make a HeNe laser pointer but I don't think they could work that small, I am considering both for future projects a HeNe in the shape of a Star Trek TOS phaser. I would also like to get some glass vials with neon and make mock up tubes to go inside a pointer and make it look HeNe.
Btw, Thanks for the kind words. I try to be informative so others who are into lasers don't have to break as much learning as I did lol.
@@Zenodilodon th-cam.com/video/YVtIXBbgHas/w-d-xo.html
They seem to be possible. Maybe you could get your hand on one if you're lucky. By now I have basic laser knowlage but I'm looking to get more than just diodes. Hard to find tho.
great video dude, this was the best and most informative one i've seen...very helpful. Thanks
Glad to be of help! I hope you learned a bunch and that you get some lasers going in your own projects :P
@@Zenodilodon actually i have just extracted some laser diodes and trying to sorce some parts for houseing heatsink and also trying to understand the power supply. Thanks to your video i now have a better understanding of what i am doing and what components to look for....i dont have any old laser pointers to frankenstien. i have a bunch of redundant electronic things lying around so my first laser project may take a while...Any more helpful info on building a power supply from bits and peices would be great..I subscribed to you channel and look forward to watching more of your content..Thanks again :)
Not only are you a damn nerd…. But you’re also extremely under viewed. You deserve so much more views than you have. Subbed
Dude I love you. This video is exactly the stuff I like. Good job brother! I really wish I was a nerd sometimes….. seriously though, this content is amazing
great video sir very informative
Thank you So much for this video
I remember back when I was a kid , I was crazy after seen videos of a dvd lazer that burned paper , I never got the chance to build it dvd units wore too expensive at the time , now I am 26 might be able to make it , but afraid of going blind by it 🤣🤣 anyways this video is very informative
The green laser driver mod is perfect...
I really like how you explain how they work and even many microscope shots of insode the Laser Diodes. Plus your explanation the correlation of current and voltage as a factory was an excellent way of doing so. I normally find it quite difficult to explain current to people that do not work with electronics. Excellent video!!
Thanks for the comment, I actually found it rather difficult to explain current regulation as well. I was trying to get into detail on it and went 300 retakes deep before I came up with the factory analogy.
@@Zenodilodon You're very welcome sir, I've built quite the few lasers (very high powered lasers) and your video opened some doors for the odd form factors (not the normal T-018 or the T-013 i believe). The microscope internal images were extremely helpful. I need to get a microscope. Mine is old and is in sad shape. Again thank you for this excellent video!
@@anthonyvolkman2338 High powered lasers are certainly something I need to get into more myself on a casual level. I hope to pick up something like a laserscope in the future to mess around with. I am glad this video was interesting for some one with your experience, I did what I could to make this both useful for people who where just getting into lasers and interesting enough with more obscure information as to make it enjoyable for enthusiasts. Having a microscope is a great thing and I certainly recommend it, there is nothing quite like being able to see miniature technology and stuff first hand! No worries on the age of the microscope, I think my hails from the 70s I just managed to clean it up and mount a decent cellphone on it with decent results.
@@Zenodilodon I thank you for that, my microscope's lenses are messed up. You did extremely well with making this video for people just starting and enthusiasts that build high power lasers. I enjoyed every bit of of this vid.
Dude, I was like proper glued to my screen, screw telenovela or the soaps, dont know what it is but you got me hooked solid, lazer junkie for life!!! Very informative, brought down to us in layman terms in a non condescending manner, and actually very entertaining.
Ding ding, new sub for your channel!!
Glad you enjoyed! Welcome aboard and happy to have you as a subscriber.
Simply AWESOME dude!
I bet you're going to use this information quite often!
@@Zenodilodon You betcha, mind if i post a link on laserpointerforums cos you rock !
@@qutube100 Absolutely, I post these videos to help as many as I can and to share knowledge far and wide!
@@Zenodilodon It is done....
@@qutube100 Friggin awesome! thanks for spreading the laser word!
Bro.., you're fuckin' awesome. I don't comment or like ever.., once in every 2-5 years at best, anyways, absolutely awesome how you not only tear apart to gather the components, but also view them, and bring them to their breaking point., Lol.., the fact that the video is long is in my opinion, even better. Not for everyone, but for those of us who tore apart our RC cars when we were kids (3 days max after Christmas).., lol, well, we still do.
Very good sharing
Very cool! Never seen some of these crazy LD packages that come out of the laptop burners. Also interested in learning more about the dual wavelength output from the single die. Can you run both wavelengths at the same time?
Thanks! Yes both can be run at once however this would require 2 drivers that could be both tied to - on the LD. Many laser drivers designs are regulated on the - side so they cannot be combined to run both at once. The drivers would need to regulate on the positive side of the output.
Thanks for the valuable info. I wonder if it is possible to measure V or A during the CD/DVD player operates. That could be another way of measuring the operation voltage and current of the diot.
You can if you have a scope that can read pulses quickly. The down side is that even if you do get the readings they will be higher than recommended for continuous wave use such as in a DIY pointer/module.
I'd like more detail on collimating the laser. Are there different qualities of lenses? With the right lens, can you send your beam further than most with less expansion? Do certain lasers emitters make non circular beams that need correction? Thanks
Most laser diodes make a bar/rectangle beam. Usually these are mulimode laser diodes. There are a few single mode laser diodes that will give you nice decently round beams, usually the ones for optical media like DVD or BR, There is also green and blue single mode laser diodes but they are all lower power. The higher in power you typically go the worse your laser diode's beam will be on one axis. This can be corrected to a degree with cylindrical lenses or an anamorphic prism pair. There are some FAC corrected laser diodes, however they look to only make uniform squares by reduction of one axis and an increase on the perpendicular axis of the beam. There are different lenses, I typically go for a dual or triple element lens that is AR coated for the wavelength it's being used for. However those come with a loss of output due to the beam going through more than one lens. For the best power a single element is often used esp for those who want burning laser pointers. I prefer the beam tightness more myself these days which is why I tend to go for compound lenses.
Might be fun if you made a video in the different types of coatings 👀
Question from a rather newbie... Is there a way to use whatever driver is on the "sled" with the diode already? Just provide the proper voltage to wherever needed? Thank you for the amazing video!
I think only the setting potentiometer and maybe an opamp are on the sled. The actual diode driver is on the main board of the optical drive otherwise IIRC. On many ribbon cables for sleds there is a point with 2 exposed connections. These go to the laser diode and there is a blob of solder connecting the 2 connections on the ribbon cable of which is removed when the sled is installed. This is to prevent ESD going to the diode. I could be mistaken but I don't think there is a whole constant current driver on the sled.
And I thought I was rough on my equipment. That Fluke looks like it was salvaged from a warzone. 👍
That meter is a bodge of like 3 broken meters my friend put together from salvaged parts from work. Worth it 100% Fluke is good stuff!
Those Open Can Laser Diodes Are Powerful And It's Almost 300mw And Very Visible Wavelength!!!
Where did you get those high current meter wires? They plug in but have high current capabilities. Also what full spectrum camera do you use? I use a nofified flip phone camera. It's cheap and crappy but it works.
The wires for the meter I used where given to me in a box of misc stuff. I am certain if you look for a good brand of wires/probes for a meter such as Fluke or Fieldpiece you can find some really good ones.
The full spectrum cameras I used are modified camera phones, This one was a modified Samsung Galaxy S3. You can do mods on nearly any camera phone by removing the IR filter and there are some tutorials online. I find the easiest ones are the Samsung phones before the Galaxy S4, the hardest ones are the Iphones, it can be done however the filter is glue onto the CCD and is less than half a millimeter from the sensor. Since camera phones have a wide variety of construction I have not posted a video on the topic myself. You can also make them with web cheap web cameras and most security cameras are already set up to pick up IR. If you choose to make your own I would suggest finding an unused older phone to try modifying or look into a cheap web cam and removing the filter in that, the parts are bigger and much friendlier to work on if you are not so experienced with working on very small stuff.
@@Zenodilodon I have modified a few phone cameras to be a Full spectrum camera. Not too hard at all. The auto focus type is more difficult however. Thank you for the insight though.
Hi, I have a laser RGB, brand: "Seven Stars", model: "SD10000+RGB" and one of the galvos are broken, what i have to take in mind when i replace the galvos?
The 2 biggest things of concern are the speed of which you scan at and the height of the laser head output aperture from the optical table. Here are 2 videos I put out that cover laser galvos and here are some sites of which to get galvos other than eBay where you can simple search " Galvo kit "

Couldn't u have found the pins by measuring the voltage drop ? The lower the drop the lower the energy, so it's possible to differentiate wavelengths that way, no ?
You can probably do that to a degree with laser diodes. I have not used that method though as I handle many wavelengths and junctions sizes, many of which exceed the voltage of my meter's diode check. That and after doing this for years many of the pinouts are memorized.
I got my hands on a few DVD burners, but their diodes are super small and likely are not that powerful. I also got my hands on an old MacBook Pro, that diode looks more serious, will be testing it out soon.
The size of the diode canister doesn't always mean the same power. The most important thing to look for is write speed. Typically the faster the drive writes the more power is needed to burn the disk faster.
I once extracted an open can diode by putting a punch onto the bit of metal that the actual diode structure is bonded to and bashing it out with a hammer. I'm suprised it actually worked afterwards XD
Some laser diodes here have absolute horror stories and yet still work. It's astonishing how much abuse they can seem to handle.
@@Zenodilodon 2 years ago, i took out a nichia green diode from a projector, i didn't know much about laser diodes at the time so I powered it with a 9v battery, i even dropped in water and poured hot glue on it (by mistake of corse) it still works today! (I had to decan it though)
Hi, i have a broken green laser and i have a 4 pin laser diode from my dvd player, can i somehow mount my diode on the laser motherboard?
Yes you can, but you won't be able to make green work with CD/DVD laser diodes. You can make them IR or red using those diodes, however you may run into problems with the lenses. Either way you slice it the modification will be tricky. You will also have to have a compatible laser driver and you will also need to set the proper current.
1000x better than styropyro videos
This isn't a burning channel, it's a earning channel lol
So with the infrared lasers, would I be able to use the crystal from a green laser pointer to convert it to green? Since the pump diode is IR it should work. Right? I know it would reduce the output, but an invisible burning death ray is kinda terrifying.
Good question to ask.
A CD burner uses a 780nm laser diode and a green laser pump diode is 808nm. While this may not seem like a huge difference in wavelength on the level of interaction between photons and the atoms in the crystal will not be the same. a CD burning laser for this reason will not effectively pump and lase the ND:YVO4 crystal.
Zenodilodon thanks for your reply! I also have another question. My “flat” laser diode has 10 legs vs your example. I tried your pin out with no luck. Any other ideas?
@@zentuckyfriedckn2587 You will have to closely inspect your laser diode for the pins that come off the laser diode and go out to the external pins, they are pretty easy to spot, using a small magnifying glass helps quite a bit or try using a cellphone camera to get a good macro image. In addition to this you can also tape a small lens either from a laser or other device to enhance the phones ability to capture images very upclose.
I want to do a full laser build using only components from the dvd drive......
Form factor does not matter to me as I'm planning to put it all in a box that's to big.
Hey Bro! I made my first burning laser back in the 7th grade and have been hooked since. Where are you from man? Not many people in my area do anything like this.
Working with lasers is a never ending horizon, I am in Wisconsin.
@@Zenodilodon lol damn I'm all the way over in Oregon
@@jjhack3r Luckily we can be internet friends! There is a whole online community of other laser enthusiast. You can find them on LaserDiodeForums, Photonlexicon, and the FB page Laserists.
@@Zenodilodon lol yeah but it's never the same as working with someone on a project
@@jjhack3r I highly agree with that, it really does lack in a dynamic and there are so many things you pick up while working with some one that you might not otherwise learn. If you go on some of the online sites you may find others in your area whom might enjoy your company as well.
how can i find out the positive and negative pins for the square laser diode that have 4 pins on top and 4 pins on the bottom and 2 pins in the middle on the left side and right side????
The best way is by visual inspection. With how many semiconductors/sensors there are nearly everything would trip a diode check/electrical probing. If you choose to use a DMM in diode check look for something with a 1.2v drop or higher that's usually the laser diode.
@@Zenodilodon can you make a video on it? That would help out so much. Some times i have a hard time comprehending these kind of stuff i guess you can say im a little retarded 🙃😆 🤣 😂 but this video helping me understand a couple of things when it comes to lasers
Just enjoy like a Movie 🎥🎥🎥🍿🍿
Damn I want your power supply where did you get it from?
I made it using a laptop power supply, DC-DC step down converter put into an x-acto knife box. Honestly have to make improvements as I keep blowing the DC-DC converter.
Would be awesome if you made a second version of this video, tearing down Blu-ray optical sleds as well, and maybe even showing some of the scanning laser microscope builds that are easily doable when using these high precision optical sleds.
If you don’t follow “breaking taps“ TH-cam channel… I highly suggest you check him out and his confocal laser microscope he built!
All of your followers are aware of your genius… And I would love to see you dabble with more science related stuff. You’re too smart to stick to only show lasers 😁 you could break open the whole community and add so much incredible stuff!
Also looking forward to you building a spectrometer. Did you see “les’ lab” new video last week about removing the coating from the raspberry pi camera?
So that it would properly register deeper UV wavelengths!? Such a cool build.
I have not seen breaking taps, I will have to check that out. I don't get many blu-ray devices in these days. I got out of computers since the Windows7 days when I stopped gaming and loathed working on peoples computers. There is only so many times you can remove viruses before you want to pull your hair out. Lasers are much nicer in that aspect, no BS software.
Larger projects will be in the works as I am doing more with Adam, but there is also background stuff going on too, I sent you an e-mail about some of that. I do want to make an electron scanning microscope and do some hacks on my microscope. All in due time sir, all in due time.
I actually have a spectrometer, I got it over winter and it's an custom Flip based on an Ocean Optics USB4000 It can do 200-800nm with I think .1nm resolution. It's no DIY home gamer's device and it pretty top notch. It should be making it's first appearance in one of the next videos where I will be working on a 488nm DPSS laser. I plan to measure the quality of the light between that, and argon ion, and direct diode just so I can show how tight the 488nm band from the DPSS is. It makes a diode diode look like garbage and the speckle is to good you can see each beam of speckle in fog. It looks like the hyperdrive was just fired up in the millennium falcon!
@@Zenodilodon I’m a big fan of ocean optics! I bought a pallet of their equipment three or four years ago, literally like 400 pounds of their high and top notch units. Mostly new stock!
ended up selling over a dozen USB2000 and USB4000 units that were like new with fresh calibration. And parting out several dozen others in lots.
It was from Oak Ridge national Lab here where I live. (Home of the atom bomb)
With a bit of research, you can find wonderful government auctions like that!!! Also a lot of colleges and schools who have auctions, throughout all of academia! Many of which have optics labs and MACHINE SHOPSMACHINE SHOPS who are getting rid of stuff for scrap price! Industrial auctions are also good to watch for.
You’d be surprised how much laser, optics, and spectrometry equipment gets used in the weirdest most random places in industry. Like welding shops 😂 they’ll have tons of spectrometers and things to test they’re cutting and cooling fluids. And a lot of times you’ll find that it was too complicated for them to use so it’s new in the box!
You can buy things for pennies on the dollar. Sometimes almost scrap price. That’s a big part of my business. You never know what you’ll find, it might be a complete waste of time, or you might hit the jackpot. Don’t get me wrong, it’s never a waste of time. There’s always tons of money to be made. But I focus on things that are easy to ship in standard flat rate USPS boxes…
Anything bigger than that… I try to avoid unless I’m interested in it personally.
I made a fortune on that ocean optics buy. I don’t remember exactly because I bought a lot of stuff that day. A truckload. But that pallet cost me about the price of a single spectrometer. And after my money was made…I got to keep stacks of beautiful spectrometry gear!!! .
Sold a lot of it to a guy on eBay who is still reselling it I think. He sells ocean optics parts on eBay, everything from the empty enclosures, to full kits that you put together yourself.
I gave him a sweet deal on a box that probably weighed over 100 pounds with nothing but new stock ocean optics parts. I had already made my money and was glad to pass on a good deal while still making more money in the process!
I kept several units for myself, including a full Raman spectroscopy setup, And several spectrometers. But honestly the only one I use regular is the USB4000! Its had a bit of customizing work done to it by ocean optics.
It has the “LUMOGEN” coating on the CCD sensor, I think that’s how it’s spelt. You can find info about it online.
Basically they take the CCD sensor, remove the optical window, and add a specialized coding which gives better UV resolution and deeper ranges. I think you can still find the bear sensors online to upgrade a current ocean optics spectrometer.
I’ve been impressed with it, and their company in general.
I still have several ocean optics units that I Assembled and calibrated myself from new stock parts. calibrated them with nist traceable calibration sources. I probably don’t have $200 invested in them, and it’s as useful and accurate as the USB 4000. But on a budget!
That really says a lot about ocean optics design and quality. That somebody like myself… Who isn’t an optics professional…could assemble A unit from parts, and calibrate it to perform on a high level
I love their stuff, their build quality is insane and their optics are on par with anything else I’ve seen including Thor and Edmond!
I’ve been super impressed with some of the DIY spectrometer builds. Especially the one by “les’ lab” he designed and share it on TH-cam. It’s accurate to within about 1.5 nm if tuned properly… And it’s a pretty impressive unit which is easy to assemble.
I’ve actually read through that email you sent a few times, it’s super interesting and I can’t wait to see more about some of that stuff! Where did you get your spectrometry setup?
@@hullinstruments I got my spectrometer from the eBay seller Spectrophoton. The seller wanted to know more about the B&W Tek 473nm lasers and wanted to put me on retainer for future information and modification information. I told them that given the amount of changes and parts that might need to be made to make them into good 946nm units that I did not feel comfortable taking $ as it could be of crap shoot once the parts and labor where factored in. We came to a deal and they sent over the Flip 972 with a Ocean Optics mainboord on it for that as they had a few of them. I figured it was the best deal for both of us as they would be in a similar boat of finding stuff cheap and rebuilding them so it was more equitable on their end.
If you still have spectrometers I have a good friend who is in the laser industry who is looking for one and has been on the hunt for a while for a good one to get ideally an Ocean Optics one would be excellent for him if it's something that he can get his hands on.
I bet the e-mail was an interesting read and probably explains a bit. I tell ya you don't always get to choose the cards in your hand but you have to try to play them as well as you can while you have them. All in all i am doing pretty good and have done more than I sure as heck thought I would. It's an abundance of life lived though I tell ya. At least I am all the wiser because of it all.
One of the best things to happen was meeting Adam in that sense as it's given me an opportunity to continue my growth and do more in life. There is a lot that is going to happen and it's going to be a rocketship ride with the exponential curve on upwards that is in front of me.
How can I get a power supply like yours?
The adjustable power supply I used was made in an x-acto knife box with a simple adjustable DC to DC step down converter and laptop PSU. I rewired the step down converter with external pots and placed in a current/voltage display.
I love your videos! But I have yet to find a source on TH-cam or online that discusses salvaging industrial laser diode‘s and modules.
A buddy of mine owns a local industrial recycling yard. They get hundreds of tons per week and crush everything. I’m one of the only people allowed to buy from the place… And I’ve run across several sources of industrial lasers.
I get all kinds of beautiful stuff from there.
If it’s really nice stuff… I recalibrate/repair it and put it on eBay… Or sell it for parts. That helps fund my electronics lab.
But if it has a little to no resell value, or if it’s a “risky item” that I don’t want to sell (because I don’t know how or what to test… And don’t want problem items which cause multiple returns)... then I disassemble those types of mechanisms and keep the parts or do experiments.
Some guy brought literally a ton of “micromotion” branded gas sensors. Many of which had optics and lasers inside. Another guy brought thousands of pounds of old retired Comcast and Motorola telecommunications stuff. I don’t do much with microwave stuff because it’s really black magic… no need to save multi hundred dollar gold ceramic microwave transistors when I don’t have a way to test them and no one really has a use for them.
I was about to dump it all back in the scrapheap when I spotted a fiber optic module.
Opened it up to to find loads of fibers and lasers… But most of the fibers had been carelessly snipped.!…
And all kinds of weird and crazy modules.
Most of the stuff has no resale value… Even if it works. No one has a use for old telecommunication stuff that is obsolete. And companies that would need stuff like gas laser sensors… They’re not going to take a chance buying a used part. They’re going to spend the money buying something brand new and certified.
I hate to think of the amount of professional projectors that I’ve let go. I didn’t know any of them were laser-based units… And I had already collected dozens of pounds of dichroic glass spheres and lenses. I had no idea some of them contain laser modules. That makes me feel sick.
But my Question to you is… What types of units or machinery should I be on the lookout for where I could find industrial quality lasers? What about Blu-ray players or industrial video equipment? Because so far all I know to look for is projectors, gas sensors, and the random communications fiber lasers and such. But I really would love to find some powerful laser diode’s or pump lasers.
I have almost a dozen working x-ray machines… Some of them exceptionally nice and modern. But none of them use alignment lasers because they use those safe beams so not to bind patients.
Hope to find some information on what I should look out for. Because most of the stuff brought to this yard is from government facilities and large machine shops and such… Surely there’s some good stuff in there.
Thanks for your time.
Please send me an E-mail at Zenodilodon@gmail.com I'd like to cover this in better detail through that format as there is quite a lot of information to cover. I look forward to hearing from you!
Holy Sh** .. Iggy Pop just sorted out my laser conundrum. That's not a bad day in my world. :)
Righteous thing to say, laser on!
You'll have to do the rest of your videos shirtless
I'm watching... 👀📺
I'd like to see a laser die up close like this, but being slowly powered on👀
What does TTL stand for?
Transistor Transistor Logic
you are the fucking man. instantly subbed.
Welcome aboard mate!
Do you sell any lasers? I got heavy into lasers recently as I had a few unnecessary dvd drives from servers I've refurbished or recycled. Im looking to build a powerful laser similar to a light saber haha. I also want a laser that can burn for professional reasons ill explain privately. Shoot me a pm man! I also sent you a fb request. Thanks!
Great videos!
And the power is around 50-200mw. That's crazy
You connected the resistor to the wrong pins of the the lm317
Well darn, I sure did...lol
12 pin type???
Yeah they come from laptops quite often.
seria bueno un video en espa;ol
Bien por usted*...
Este video involucró múltiples pruebas, matando múltiples buenos láseres, y mucho tiempo tanto en demostraciones prácticas para respaldar mis resultados como para hacerlo tan evidente y fácil de usar y configurar eléctrica, óptica y mecánicamente... y usted quiere te atendió en español.

Dude, have you ever seen Wayne's World? If not, you need to see it.
I have never seen it, I'll have to put that on the list of movies to watch!
What does open can😅 mean
The metal cover that goes over the front of a laser diode is called a can. Open can is where this little cover wasn't installed by the manufacturer or that the can as was otherwise removed.
Great videos.
But they have put too many ads in to finish watching for now. Sorry.
You will now have only ads in the beginning without interruption from there on out This will apply to everyone who watches the video.
Consider showing fiscal support so I can make ads a thing of the past!
No laser diode from old cd player.555
Can I have a laser please
What is your location? I can probably put you in contact with someone in your area that might be able to help you with laser stuff. In general I don't ship lasers outside of the US.
Never mine I don't what laser
I'm From Philippines
I don't what's laser
I hope ur a Linux guy.. if not,u r Just really, really gay.with that said:thanx 4 the vid..clear explanation,impressing but smooth handmoves..points of attention:1 used camera angles are at least discussable.2 tension-building music till climax-handling 2 Spice things up?....looking forward 2 the next one
Are you a bot? I honestly can't tell...
Not gay, just obsessed with rainbows. Used to be into Linux, probably will go back. Glad you found the video fabulous. About any sort of tension building climax spicy handling...
You wish I had an only fans you naughty boy!
XOXOXO
I can see in some of these clips the camera sensor has suffered from some laser damage
Oh yes, many cameras get toasted on this channel.
@@Zenodilodon would definitely like to see the footage of one of the cameras getting roasted i think itd be a great representation of why class 3 and higher lasers are dangerous
Also it would give a great example to those who dont know what would happen if they ever caught a reflected beam to the naked eye
Ok tiktoker
Don't you have a bridge to attend too?
This video is so far over my head 😢
With a little bit of time you'll pick up the stuff no problem quicker than I did. People like you are the reason I post such in depth videos on this stuff!
