Making A Giant 100W LED Laser Gun!

[@DiablosCurse_]

The little larva moving around in the garage was great.

[@GeekMustHave]

You are such a Geek. The expression on your face when you took the Clear tube out the packing was priceless. I like your truly casual presentation style. I'm looking forward to watching more of your videos.

[@annemarievanpeer120]

I recently stumbled across your channel through the model castle and the elemental tomes, and I just wanted to say a) i ADORE everything you do, it's super cool and damn u have talent and b) I am LIVING for the cyberpunk witch aesthetic 😍😭👌👌

[@svens.4694]

Martina , why is watching you build stuff so freakin calming and satisfying? :D You should drag Hansi more often in front of the camera though, i love to see the two of you as a team :) Next best thing to the intro in this video was the wood cutting part, where the cuts where matching the music so very very well. Awesome video, i'm excited for the next part :D Thank you!

[@KHx1GamingPlays]

if the glass tube diffused the light it would probably look awesome as a wall decoration.

10:50 goodtimeswithscar here~~ xD That song always reminds me of his timelapses lol

[@Travelinmatt1976]

It's a little late now, but you could have frosted the tube by sanding it so the whole thing would light up. Great project, can't wait to see it finished!

[@murrayingledew8943]

I love what you do! This is such a great video. Who else stops a build to check out a weird caterpillar walking by? Can't wait for part 2.

[@jvleugels]

At the 30 V supply you are drawing about 0.7 A at most in your tests. So in reality your 100 W LED is just a 25 W LED at most. (This happens a lot when buying these from China)

[@Nerdforge]

We noticed this as well. Two theories: our bench power supply can't go higher than 30 volts. The LED i tested needs 32-34, it may draw a higher current at a higher voltage, which we will test. I remember having read someone had to drive it at over 36 volts to get it up to anywhere near 3 amps, which I guess sucks for the longevity of the chip. The second theory is that it's just a bad chinese product.

[@SianaGearz]

@@Nerdforge Honestly 25W is a comfy enough value and quite a good amount of light, i don't think you necessarily want to push it much further than that. Let's say it's a 10-series LED (i remember bigclivedotcom looking at these, should be about right), you're driving it right around the bottom of the threshold range and i'd say looks about right to me. Tried it with a super low current, seen whether it lights up consistently at all? If it does, and you can tell that there's 100 LEDs in there, 10 rows, 10 columns, all lit up, then i'd say it's a perfectly great product, but you might have a bit of difficulty finding one that isn't made out of junk LEDs. Banggood stuff sure usually isn't the worst though. I mean neither your LED mount nor your cooling arrangement nor the spring contacts seem even borderline fit for a 100W heater. And the further you push it beyond the threshold, the less efficient it will be, so it may not even be necessarily worth it.

[@Nerdforge]

@@SianaGearz Thanks, that's a good tip! I'll explain a bit more in the next video, but the idea was never to have the gun permanently powered. The arduino will control how long you are allowed to hold the trigger button down, before having to do a cooldown period. Hence we can carefully adjust it so it's allowed to cool enough before blasting off again! The brighter the better!

[@farbenformenlicht]

You have to drive those leds with a constant current instead of constant voltage. Otherwise you can destroy the led.

[@SianaGearz]

@@farbenformenlicht Constant current and constant voltage are strictly equivalent to each other - if they're actually constant. You have more leeway to get the current regulation wrong than voltage regulation, but with these 10x10 array LEDs, it balances out anyway. According to how these LEDs usually react to voltage (like they light pretty brightly sub 30V and don't reach full brightness until 36 or 38 or so) there's probably plenty of resistance in the bond wires within the LED package which contributes to current limiting. It should be just fine, and if the LED unit dies, well that's just the quality of individual LED elements, nothing you can do about that other than underdrive it on the whole. There is some temperature dependence, with bond having PTC characteristic and LED having NTC characteristic, but that's like tens of millivolts, not enough to matter.

[@jayzo]

I don't know if you've already filmed Part 2 or not, but you can get switches shaped like triggers so you can activate the laser just like you're firing a gun. You could have a separate switch for the EL-wire and LED strips.

[@Rainbow__cookie]

8:29 i came here for the Caterpillar

[@francoisstevens4349]

Try using a Fresnel lens to effectively direct the light from the LED.

[@lucatosatti7071]

Very nice job! But a little tip for the led mechanism, about a possible thermal issue: now, when you want change color of the led, you disconnect it from the heatsink. This mean you don't use a thermal paste, usefull for the thermal exchange from the led to the heatsink. Without the paste, if you will running the led at maximum power (how the other guys said, with the actual voltage and courrent, the power is under 30 watts), it will risk to overheating. So, if you can, change the mechanism, so that the heatsink is permanently connect to the led, with the thermal paste.

[@djart4715]

I LOVE her!!!! She’s the dopest creative mind out there!

[@Maerahn]

You are an insane genius and this world needs more of you!

[@helenf4214]

Just started to watch this and I like how you wanted to be able to switch the LED from ‘kill’ to ‘stun’. Yes, this was the term you were looking for..😲

[@ceejayrob]

If you made the tube opaque, it would glow when you switched on the LED. You could do that with some acetone if it’s the right type of plastic.

[@donaldburkhard7932]

Make LED holder out of aluminum as would make good heat-sink, plus plastic may melt. Put regular computer heat on back of LED. Rotational disc with different color “filters” for different colors of light?

[@ashkaztra4646]

Love the video! And as a fellow Norwegian, that catepillar is some sort of bjørnespinner, though I can't say which. They're often called woolly bears in English, for their fuzz.

[@dustymiller8752]

It's actually a type of moth larvae though the exact species escapes me.....

[@Travelinmatt1976]

@8:25 In the US we call those Woolly Worms, or Woolly Bears, and the all black ones come from the Giant Leopard Moth. A white moth with black leopard spots and also blue iridescent spots. I'm not sure about the ones in Norway though.

I wonder if you could fit a Fresnel lens in front of the led. That would certainly help you focus the beam.

Styropyro has a 100w Laser. This is extremly Powerful.

[@JAKOB1977]

anybody can make a 100W laser gun.. you just need to lay down the 170USD for the NUBM31T (95W) and then overdrive it a tad.i.ebayimg.com/images/g/ZpIAAOSw17lecafX/s-l400.jpg It's 20x 455nm blue lasers in a sink array.. www.opli.net/media/3597/laser-multi-chip-package-osram-june.jpg the biggest issues are to get them to align in a single beam with a decent divergence as the ball-lens top layer will splash it, to the moon and back... can purchase one atm for 170USD incl, delivery to Denmark, but simply don't have the optics to make anything beautiful out of it. and yeah, nothing laser in the above video, just tacky clickbait but whatever some people roll like that for attention and get strangers to nurse their weak ego online. Tired of misleading click baits and seeing videos that has nothing in common what their title..

I think It would be better if you use BEC and step down from a 6S lipo battery or higher. Because step up requires lot of current to reach higher voltages

[@Mitch3D]

you can buy projector lenses for LED's on the internets, that would help you focus the light like a laser.

How did that tube not break in transit?!

[@dscrive]

If you could get some fiber optic tubes like they use for those lights (the ones that look like glowing spaghetti) I think you might be able to fill part of the tube with them and it might help collimate the light to better simulate a laser . A quick googling on "will a bundle of fiber optic tubes collimate light" gets me some results that make me think it should work. I hear everyone else but us in the USA has ultra fast internet, so you might be able to get some scrape fiber optics from an internet company, although I think it might be too fine. I haven't messed with fiber optics so I'm really just speculating here :D

Fun fact: In the USA there is not legal limit to the size or strength of laser that you can own as a civilian. As long as you don't point them at airplanes and use them only on your property or property that you have permission to use big lasers on, you can go for it. you want a 3000 watt laser, just throw $20k at the right person and it technically isn't illegal. I think this is because no one who has that powerful of a laser has been stupid enough with it to get them banned, but I still find it a little concerning XD
