Check out some of my other videos then.

Thanks for the feedback, buddy!

Thanks for subscribing! Yes, it's a tiny electron picture tube from a small CRT television. I have no current or future plans for this tube. This video was just an experimental test run to see if the tube was still functional. That being said, I do have much larger cathode ray tubes in stock that I'll be using for home projects so stay tuned!

@JHERU cool man, I will definitely be looking for that. Your mini-ray tube was definitely functional. I am actually collecting a few of these t.v.s due to them becoming extinct. I'm 47 and while I'm not an old man, I've seen things come and go and looking back, I wish I was a bit wiser. Like my candy apple red, 1985 RX-7. Had I but known.... anyways, I will be collecting several and just hiding them. Not so much for selling an antique but future experiments as well. I mean, have you seen the prices of flybacks lately? And those cathode ray tubes will be worth there weight in,... probably salt, one day soon. The way things are going,... probably sooner than later. Sorry about such a long story here but,... I remember growing up and my parents telling me, as a very young child, to.... back away from the screen, don't sit so close to the t.v. and on and on....I can't help but to wonder what effect, if any, it may or may not have had.... makes one think, ... I mean, our government has lies to us about almost everything as it is,.... I'm sure they didn't, one day, just stop with the b.s. ... anyway, thanks man, I will be watching for those vids.

This laser you can find on eBay from Techhood products.

@@JHERU Thank you!

Sweet! Yeah it took a while to configure this PSU and I finally got it working.

DVD optical drives are mostly where I salvage regulator packages from, in older and newer models they're pretty consistent. You can also find them in old power supplies. Make sure to test them before putting the semiconductors to actual use.

Oh that's genius. I gotta experiment with that idea, thanks friend!

Yeah you're right that does make more sense. Thanks for the correction!

Thanks. Unfortunately, building a reliable laser power meter from scratch would be very difficult. The accuracy and sensitivity of a power meter are the biggest factors. As much as they are useful for laser projects, buying a professional meter comes at an expensive cost (not including maintenance) and is something that I'd like to invest in the foreseeable future.

Hi, thanks for watching the content. If you strip each cable off you'll be able to see the color code of each wire. In this case, the model of this DC brushless fan is 'PVA092G12P' by Foxconn and is rated for 12V at 390mA (4.7W). The wiring configuration for turning on the fan is as follows: P+ output is red + yellow wires tied together while the N- output is blue + black wires tied together. I hope that helps!

Woah, this brings me back. Still repairing earphones to this day.

Thanks I'm glad you enjoy the laser content. I suggest re-watching the video though, the laser is being sold as "5mW" as stated in the seller's link in the description and the laser can clearly burn PVC tape, try watching at 1:28 in the video, its hard to miss once it starts burning.

Hi, I would suggest a constant current regulated driver for driving the diode and a threaded aperture for adjusting the beam to a focused point at a distance.

Hi, yeah I don't see why not. You'll want a quality glass G7 lens or something similar for burning objects at a farther distance while taming the divergence down a few degrees to reduce any losses along the beam path.

Sir, how to make invisible laser beam like this video kzfaq.info/get/bejne/gq6XYLqk2MzZj30.htmlsi=dgfACj0-9HXSKNIg can you give tutorial vedio please

Haha, yeah its unbelievable how much of a beating its been through, never seen anything like it. The battery was still okay but everything else was permanently damaged. Maybe it got hit by more than one vehicle. No, there was nothing to connect it to just a monstrosity!

Hi, thanks for checking out the new video. I have made a few videos on these cheap bare diodes and I haven't been able to power them on above 40mW, even when focused to the absolute limit. In its current state, the laser is able to poke holes and cut through thin vinyl plastic with relative ease and faint wisps of smoke are observed when pointed against thicker materials. Its nothing that I ain't seen before when working with these diodes. In theory, if I were to swap out the lens with a higher quality one and captured more of the light through a longer aperture might increase the total optical power but probably not by much.

Thanks! The resistors shown and used in this video are valued for 30kOhm and 33kOhm.

Hello! Thanks for reaching out. All laser eye gear must come from a reputable and certified source. Do not buy from Amazon or eBay. I'd recommend Thorlabs, Laservision or LaserGlow Technologies. For a project like this, I'd recommend laser safety glasses that cover the near-IR/IR wavelength with an optical density of at least OD 5+. The higher the density the better protection there is. For example, glasses that are made for 780nm-808nm of laser light would suffice. As long as the desired wavelength is covered you'll be safe from harmful radiation. I hope that helps!

​@@JHERU Thank you! I've purchased from Thorlabs :)

@@ozgunkilicafsar8122 Your welcome! Stay safe and have fun.

🙂 Thanks! Appreciate the support. I think you mean the 7805 regulator? Xbox 360 laser diodes are generally quite lower in output power at 5mW max and are good as Class 1M laser pointers. The diodes should only output 650nm red. If you reflect the diode's AR coated lens in the canister at an angle in white light you'll see a bluish tint which is typical of red diodes. I'd recommend a voltage of 8V or a potential thereof at low operating current (20mA-30mA) and go from there. The 7805 driver would work for this and yeah two 10kOhm resistors should be okay, I'd configure them in-series across the P+ pins or in parallel config at a lower voltage.

@JHERU thanks I appreciate that I'll can definitely steer my way around now, hey have you done any laser lightsabers I have been seeing them around lately

Thanks for the feedback! I can probably pull off a laser build walk through within the next few videos coming up, since I already have a dozen laser diodes and modules on hand. Hopefully my videos have given you at least an idea of where to start and what to expect.

@@JHERU Happy to be of service

Hi, Matt, thanks for the comment! Indeed, this laser is set to 405nm of visible, violet light. "In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, some of which humans perceive as similar to violet. In common usage, both terms are used to refer to a variety of colors between blue and red in hue.." - Wikipedia Also, check out this link below for more information regarding 'chromaticity coordinates.' www.androidauthority.com/color-accuracy-mobile-devices-part-1-879888/

Thanks!

1:1 ratio of citric acid and sodium bicarbonate + distilled water for the reaction to begin. There are many ways of producing hydrogen gas but this is likely the safest approach above all else.

Thanks for watching!
