Stunning video you did there (as usual!). Thank you for opening the Cube! Your calculations, meticulous measurements and describing "what's inside" were top-notch, totally! I think we have to start working on 10W LaserCube to celebrate 1M subs with you! 😁
Thanks for the shout out! Looks like the laser head might be manufactured by OPT. Very glad to see that there is a glass plate installed in front of your reds. Those are probably open can and I have seen those glass plates be a savior for open can reds. That is a bit of power in a nice little box. I don't recognize the galvos, any markings on them/the amp? Excellent video, and review! Oh, one interesting thing to try with your higher power laser. Hang a black piece of thin fabric up and can the laser on it with a pattern. You should clearly hear the laser firing on the fabric from 2 foot away!
Also, a slight correction to your understanding of the lenses. You're partially correct, however the fast axis correction is normally on the laser diode, I think they are on your reds. The 3 optics after the laser diode/FAC that you see kind of work like this. The first lens is there to allow correction by shifting the collimating point and angle of the laser beam on the horizontal axis. The last 2 lenses are the collimating lenses, one for horizontal and one for vertical. Since the focal point of the horizontal output has been shifted the collimating lenses per axis can be done with lenses in different spaces from the laser diode. This break of the 2 axis allows for various trade offs like having a thinner fast axis for the knife edge mirrors with I think slightly more divergence VS the slow having a wider beam at the start but lower divergence overall. With cylindrical lenses the real trick is to think of a single laser is behaving like 2 independent ones in the same space, or at least is does for me. It's actually astonishing how well these lenses collimate multimode lasers diodes. I might be a fan of good old spherical lenses, but they limitations in flexibility.
First time looking inside one of these units. Very cool. Way more complicated than I thought. I knew there was a lot of specialize parts but not the complicated arrangement.
I honestly love this channel. Been watching for a good few years now, and I love how easy to understand you make everything, as well as putting an emphasis on safety whenever you do something dangerous. You remind people that while this stuff is very interesting and exciting, keeping ourselves healthy is just as important as what we gain from exploring and experimenting. Thank you for what you do!
@brainiac75 I just wanted to say thank you for all of the content you make. My field of study was electrical engineering about 100 years ago. I have never worked as an EE, so your content is the only exposure I have, so thank you very much. Keep up the great content!
750k! Congrats and well earned! I'm always excited to get notifications about new videos on your channel. It's always some really fascinating content! This one's no exception. Those indeed are some beautiful optics.
@@brainiac75 I just looked back at the videos you did in the beginning and I think the first video I remember seeing was the raw magnetic force 12 years ago I had a different name on TH-cam then but pretty sure I have been a subscriber since that video lol. I remember you getting the big magnets delivered and the tools you made to separate them and put them together lol. Looking forward to the future
Congrats on your milestone! Can't wait for you to get to a million. I absolutely love your content and enjoyed it for the la 2 years. You taught me a lot! Big hats up to you!
It's been awhile since I've been back to your channel. I've always wanted a laser cube when they first came out before C-19 started. I never got the chance. They seem like a legitimate company so I figured the specs were pretty accurate. Thanks for the unveiling!
Congrats on 750k. That thing is awesome and has a price tag to match! I have a cheap half watt laser projector I bought years ago that is still pretty cool. I really should get a decent DAC to drive it with and fire it up again.
That was absoboodylutely amazing.Your photography of the diodes and light paths was so clear. I wonder how many of your subscribers will make use of the detailed instructions on how to dismantle that laser. I know that I will ever own one and wouldn't trust myself to even turn it on if I did. But thanks for letting me see the magic.
very interesting coincidence with numbers ive been watching since the laptop meets monster magnet videos and ever since ive been hooked to this channel 😅
@@metalpipe71 yeah thanks for the heads up! these stupid scammers are all over the place but i didnt think they'd even target brainiac75.. they must be really desperate for money with the amount of channels they target..
Great video! Amazing optical design!!! Congratulations on reaching so many subs! Always loved your vids from the start. I would love to see some vids about HV or just electricity as a whole. Get yourself a large HV transformer, and pull some huge arcs :) You could also measure the spectrum of the light produced, and see how it varies with electrode material. You could also talk about power factor, resonant capacitors (and LC oscillation in general), among other things!
That was so beautiful inside.....such a work of art! And congratulations on the 750K subs. Am thankful that I found your page (and MyPlayhouse) on that old magnet destroyed fan video you guys sent to BigClive.
I press like before even watching your videos. I know it'll be good, and haven't been wrong yet. 1 Million subs is just around the corner with this type of quality content.
Looking forward to this video. I am so happy that you have reached 750 000 subscribers. You are a channel who many look up to. There are so many interesting things you have shown that is both fun and valuable to watch
Congratulations man I really love all your videos and hope to see many more from you!!! Also I've got an idea could you try and place multiple pop markers next to each other to try and get that 15s warmup time
love the equipment expose in the case by the way, I have a number of dichromic lens/mirrors and a color combining cube that still amaze me no matter how often I get to toy around with them.
Congrats on the 750k! And for the cube I have just one word.... WANTS! Not that I know for what I would need that much power and the thought also scares me - I want to keep my and others sight intact...
Yo congrats for the huge milestone on your channel! I have watched your stuff for years, forgot exactly. This laser box is a beauty of bright color and mirrors! ^^
Outstanding progress! your inquisitiveness and honesty in a world of so much turmoil and disinformation are so refreshing to my mind, like a true Oasis shining in a sea of mirages.
Congrats on the subscriber goal. But wow. if 7.6 is roughly 92% of full power... that makes that thing actually an ... 8.3 watt combined power, if my math isn't completely out of whack. That's... uh, that's a kicker.
Yeah, not sure how high it would go given 5-10 seconds more. Should be at least 8 watts. Probably the blue diode that's going crazy ;) Thanks for the early watch!
9:04 Why is there 3 red & only 1 blue laser? I thought the eyes perceive green the best, so why isn't it 1 green (then maybe 2 blue & 3 red? or whichever order our eyes best perceive red & blue?)
The aperture shield was wrongly designed though. A loose or forgotten to tighten screw should result in a closed aperture instead of open aperture. Other than that an amazing device!
I once came across you with a video about how to safely separate neodinium magnets. you didn't have many movies other than with magnets. but I found your way of explaining interesting. you don't post videos very often, but you still have 750k subscriptions. congratulations on that and i hope we see you more often.
I have a handmade handheld laser smaller than most flashlights that will hit 7.65w on an LPM. There are smaller and more powerful modules out there also.
We're all anticipating the day when you're finally testing your phased plasma rifle in the 40W range.
Hehe, wish I had more time to work on that ;)
