Maybe just state something about laser safety and then tell everyone that you're using something that has not enough power to be harmful eg: looking at the bottom of a laser mouse
You’re totally right. I need to be doing that. I have infra red filters and such that I put on this laser to ensure it’s safe, but no one else knows that. I’ll be better with that in the future! :)
Keystone Science well as you can see from some of the comments, different people display different opinions on the hazardousness of such things. Which is why it’d probably help if people with influence treated security measures as universally relevant and a thing worth a mention. Some ignore the fact that all dpss green lasers have diodes that potentially output at least >~300-500mw (~class 4 laser) which is necessary for the second harmonic generation to work as it does in said laser pointers so even if the output power of the 532nm output is relatively low, the diodes themselves are class 4 lasers and potential leakage means to expose oneself to various dangers. Aside from the obvious retinal burn, one can also dmg the eye lens and potentially get caratact, which in fact may arise from a variety of damages to the eye such as: -dmg to the DNA of the lens cells through ionising radiation and -dmg to the lens cells though the heat caused by the radiation, caratact is the aftermath of the dmg to the eye lens and ones vision gets significantly worse throughout the years.
Please come back :( love your videos so much. They are always very well explained and informative. If you are out of ideas, I'd love to see a video on the big Tesla coil. Either way, hope you are doing great and hope to see a new video soon :)
@@KingJellyfishII Cheap green laser pointers are scarier than expensive green laser pointers, they often leak a ton (many times the rated output power) of IR laser light, and that beam can easily end up misaligned with the visible beam because it bounces off of different surfaces (i.e. the visible beam bounces off the silvered back of a mirror while the IR beam bounces off the glass face, slightly changing their incident angles), so you could just *pop* go blind all of a sudden because of the invisible component of the beam bouncing off your window and hitting your eyes even if you're wearing 532nm laser safety glasses, because they aren't blocking the IR. Always, always wear laser safety glasses and never point any laser at any eyes. Yeah, you're probably going to be fine, but is it really worth the risk of being instantly and permanently blinded? Shit sucks, I know people who've had their vision damaged by the IR component of a cheap green laser. It really is instant, the time it took was imperceptible, don't take risks.
Yeah, you’re absolutely right. When I put it in the metal case, I but IR filters in front of it for that reason. So I am safe from this one, but I don’t want viewers having the impression those cheap green lasers won’t hurt them, their power rating is much higher than what is advertised
Do you want the ultimate video? Do you think you could build the Ark of the covenant which is designed to create a high voltage spark. Maybe if your able to you can figure out what it would have been used for..for all your measurements read the book: The secrets of the sacred Ark..I feel if anyone can solve this that you probably can. I hope you except this challenge
Make a 300 amp welding machine with microwave oven transformers using a single 125 volt circuit. Try and do it without 240 volts. That's a video idea. I've already made this type of project, but since no one else has made it on 125 volts, I want to see you do it. As well as get your thoughts and opinions on it. (Stick welding machine)
I don't know what size residential fuses you have for 125V, but it will draw a lot of current, 70-100A, or it's not gonna be a very good stick welder. To stick weld with 300 A you should have 25-35V arc voltage so transformer turns ratio can't be really high. Maybe with 1/4" electrode and short arc length 15V could be doable but still 40A from mains. 3-phase 400VAC ftw
You should show us how to make pocket sized scuba gear, maybe 30 breaths worth or about 20 minutes besides what you can hold your breath... A DIY flashbang grenade, and smoke grenade... Some diy thermal goggles..
I really enjoy your content. If you don’t mind me asking. What helps you to continue making your videos, even as you work on your projects? I have plans to make some of the devices you have created. And much more, I really admire your ability to make your videos, and take the time to edit them! While you are busy with the work you do. I often see myself too driven to work on the project. Which causes me to avoid recording the process of making a video. I tried convincing myself to record the videos so my children will have something to watch when I’m old and gone, or just become a crazy mad scientist? Any way.... your awesome at what you do, and your work motivates me to continue my work. I hope someday, I will be successful with my devises. Just as soon as I figure out why my last one caught on fire... 😆
Great job. Any plans for a interferometer spectrometer or sensitive receiver maybe? Something like this (ruclips.net/video/5bqujaldaCQ/видео.html) I'm seeing as a neat project for you to try also as I've been wondering about using CD/DVD/Blu-Ray/Laser Disc parts to make an interferometer cost effective homebrew and improved webcam spectrometers with LIBS, RAMAN, etc. sampling methods. Was out in the garage today organizing my microwave parts and explaining the different projects and parts that can be used with all the free rescued. Thanks for sharing! Wondering if you can make a DIY cost effective improvised system like Sam Zaloof recently did with the HP sources & kit?
Take the video where he makes a small Tesla coil and multiply everything by 10, that should get you somewhere. Also if you don't already know what you need to know to make a Tesla coil, you should not be making one. That's a great way to die of electricity. Do smaller projects first, get an understanding of how electricity flows and how to use it safely, then do the big flashy things. Tesla coils are a whole different kind of dangerous when they're running, electricity is *fast*.
They are way expensive. I don’t own one (I’ve been working on obtaining bits on eBay over time) but I have been using one at the university I went to... sadly I’m graduated now, so I don’t have access to the mirrors and lenses anymore... so I feel your pain
Yes it is, use it for an interferometer is quite challenging though. Due to the many different frequencies, the mirrors have to be very very close so the same distance apart from the beam splitter
I love all laser related projects. Thanks for this video.
You may wish to wear protective goggles though, if only for setting a proper example
Yes, this is why.

Dude, I just discovered your channel and I cannot get off the computer lol
You're amazing!
I see ThorLabs items. I take it you got those when they were being replaced? Because those are expensive.
Look how the parttern moves as he talks because of the air vibration
EYE PROTECTION!
I was a bit nervous too but he says it's just a cheap laser pointer so it's probably fine

@@Teth47 How did I not see this before commenting about the ir filter.
omg when is he going to upload I hope he is ok
can you conduct plasma through a powerful burning laser
You should make solar power heat laser like the power of the sun shootout of it and imagine using different suns
Is he okay?
Woww such an underrated channel, glad I found it
New video ?
I spent almost a minute to get told "get gud scrub."
Well hello
use . and , on desktop to navigate individual frames in the vid ;)
It's 5 AM and i dont know why i am here rn :)

Its been like 600 years since you last posted!!
Unralated, but will you and cody ever make tgat fusion reactor you guys talked about?
Hes become so natural infront of the camera, its so cool to see his growth
when will you upload new video

Catching up on all the videos i missed, sorry im new to the stream but ill be an active member from now on
No, real coders start at 0.5 as a compromise between 1 and 0
what instrument to count N number? its very fast to count manually
Please make a microwave to detonate mines from a distance. Please, please, please
Will you like to make insect sized drone with camera as no youtuber had yet made.
✔️
Do you have a twitter account? I’d like to get in touch with you soon
Have you ever considered the Nuclear Navy?
rig up a stepper motor if you want to improve accuracy
Please wear laser safety glasses
Is that fusion reactor with cody ever gonna be made?
I just read the title in your voice.
For a vid you should make a big emp
Are you coming back to youtube?
This experiment is similar to tomas yang experiment
Very Perfect 🤩🤩🤩🤩🤩🤩
Can you make a rail gun???
WHEN you’ll show HOW to MAKE giant tesla coil?

Is it possible to collimate flash light through lenses ,if possible I think it might be an interesting project !?!
Yes it is, use it for an interferometer is quite challenging though. Due to the many different frequencies, the mirrors have to be very very close so the same distance apart from the beam splitter
