Cosplay Tutorial - LED Basics

Our LED book: www.kamuicospl...
Support our videos: / kamuicosplay
Since so many of you asked, here is a new LED video tutorial!
I kept it very easy, mainly to show you how simple it is to install some fancy lights!
In my full book you’ll find full step-by-step instructions for larger circuits, instructions for making gemstones, making of different projects and schematics for anything you want to build. I even did the math for you! ☺
I’ve used regular blue 3V LEDs, 2032 button cell batteries (3V) and wires with 2x 0.14mm2. With one LED the battery lasts for around 11 hours, so perfect for a convention day!

[@butleryuuto]

This was literally the simplest LED tutorial I've ever seen. Thank you so much for this.

[@stannisthemannis8694]

I tried attaching LEDs to my cut out of Hugh Jackman but he didn't become super realistic, have I done something wrong?

[@jody024]

Did you hold it in front of a a mirror and say his name three times.....

[@MegaManXPoweredUp]

Try hot gluing knives to his knuckles

[@phyranios]

You need to pray to him. But you like have to mean it, be prepared to pay the ultimate price

[@HeirOfGlee]

This music XD , feels like your selling furniture

[@JohnPorsbjerg]

never seen this explained so simply and easy to understand, thanks!

[@TomSalazar]

How much does that LED last with the most basic battery?

[@KamuiCosplay]

In my LED book I have calculated the most basic combination but for a standard three 3V LEDs plus a 9V block battery its 27.5h.

[@AndrewBlack343]

If by "most basic battery" you mean just the LED across a button cell then that's still a difficult question to answer. There are different sizes of button cell. The different colours of LED require different Voltages to operate and as the battery runs down the LED will slowly become dimmer so it's subjective when the battery is 'done'. As the batteries aren't very expensive it's probably worth just trying one to see.

[@henkeful]

"Cuz lights are awesome, the just make Everyfhing awesome, EVERYFHING!" made me giggle xD

[@Jenifarr]

Thanks for this, Kamui :) Your English is getting very good!

[@OptimusIsHere]

I appreciate the information thank you!

[@hexyoutubeaccount]

I've seen your books around for ever but this is the first time i've seen your video tutorials and they're amazing!! I'm gonna have to buy your books now!

[@CincyPlasmaTech]

I love your energy Kamui! You really know how to bridge the gap between technology and cosplay! - Jeff

[@koenwebb4157]

The coincidence here is that I was looking at videos for ideas on how to create an Omega Yato from Fire Emblem Fates... And here I'm being taught about LEDs by someone who shares names with the Avatar.

[@KamuiCosplay]

+KoKo Webb Hope you still enjoyed the video ;D

[@DustySeven7]

A few tips for you, to help the soldering of the wires go smoother and create a stronger joint, it helps to tin the wire first. this is simply applying solder to it before soldering to the led. To help with the protection of joints, slip on heat shrink to the wire BEFORE soldering. After the soldering is done simply slide the heat shrink up over the joint and apply heat with a open flame for a short period. Just some helpful info for you.

[@hardstyler8637]

if you want to have a higher spread of the light, sand down the tip of the LED flat. not too far to cause damage.

[@RandomJoeseph]

Well f*ck me sideways! You made that way easier than I’ve been doing in my head. Great instructional video!

[@tora-chan3275]

Woher habt ihr diese superkleinen Schalter? Finde immer nur diese klobigen großen...

[@WiggilyExplodyBuddy]

Heat shrink tubing would be helpful on your connections

[@ninahong7532]

I love your tutorials and I really admire your hard work. I'm saving up to buy all of your books.

[@biggursky]

your videos have been a inspiration over the years. ill be doing my first light up prop, so i went and bought your digital books. i just wish you had amazon links to these little pieces (switches, batteries and such).

[@KamuiCosplay]

Glad to help! The problem with links is that they only work for one country and not for everybody who watches my videos, because they come from all over the world :(

[@biggursky]

oh that makes sense. you're a global cosplay asset :) ill do some Amazon searching see if i can find switches and battery holders and such. thanks!

[@CandleKern]

Good luck on your prop!!!

[@GastlyusedHex]

Thank you for sharing this, your tutorials are amazing and you have helped me figure out things j thought were impossible.

[@monokawaii1227]

can you show me where i can get everything you used in the video?

[@isiahbahe4892]

I love her accent

[@MsiP43t]

A little tip for you guys, you usually should use a resistance in front of your LED cause a LED works with rly low voltage.

[@daaajester1]

the behind the scenes at the end...lol

[@MaximusVA_]

Im happy that there exist such a good cosplayer from Germany

[@bigsteed007]

No resistors needed? 🤷🏼‍♂️

[@KamuiCosplay]

+bigsteed007 Only if your battery has more power than your LEDs need!

[@epiendless1128]

I did cringe when you connected the LEDs without a resistor. But I can't deny that it seemed to work for you. You're maybe relying on the internal resistance of the coin cell to limit the current. Normally you need a resistor to stop the LED burning out, because LEDs are very sensitive to small changes in voltage. R = (Vbat - Vled)/Current.

[@DontHaveaDegreeinReading]

You are so cute. Period!

[@TheDarkSlayeress]

I think I need to find an excuse to put the info in this video to use.... hmmmm.... hmmmm.... What to light up...? O.O I got it!!! Thank you for this video!!! Will treasure this info and pass it on to my dad!!!! >< Ghoooooooost Riderrrrrr!

[@DJHA133]

Thank you for the video! I'm working on Goblin Slayer so I'm going to try and attach some Red LEDS to an eyepatch to wear under the helmet.

[@ShadowcasterZero]

it's important to note if you use any battery other than a button cell you'll need to add a resistor to the circuit. otherwise you'll burn out your LED real quick!

[@lucidnightmare927]

Hi, how did you hang your props on to the angled wall?

[@deannavestal1394]

my daughter loves you. She fell in love with cosplaying and your videos just had made working on her costumes 100 times much easier

[@CandleKern]

THATS AMAZING!!! :D I never thought about LED placement... xD

[@KalaamNozalys]

That's interresting. I'm looking up LED stuff to try and make a simple and easy to swap tissue wrap with glowing runes on it, to wrap around weapons for LARP. Not easy to find something to make it portable and safe. (since I can't hide the battery easily inside. At least I don't think a thin and small battery like a watch one would be enough to light it up.)

[@anabelenloki]

Thanks for the tutorial this is very helpful!! Love from Spain ❤❤

[@Thiusza]

Hello, non-English speaking, so use google translator and eventhough you understand just to see how you do, I wanted to suggest that you will place your videos and subtitles hard time finding it in my language tutorials that are really good. Greetings and thank you very much, I've always wanted to do a cosplay and am learning as your videos.

[@emberN]

YES IT's AWESOME!!!

[@PKTEK]

Once again, you're inspiring. I mean, look at that work station! I am beyond jealous!

[@jaymundomakeup]

Gostei muito.. Vou fazer tbm.. Pra colocar na minha roupa de cosplay

[@shan9usfc]

Are those kinds of leds safe for eyes though? I plan to put mine inside my goggles.

[@oharuarchive]

I'm making Cyborg arms for a One punch man cosplay. Idk where I need to put the placement since I will be moving my arms a lot. Any tips?

[@mossbot763]

+Levi Ackerman I've never messed with leds but I imagine somewhere under the shoulder piece would be good since it's a pretty big piece!

[@titusfortunus2916]

Hey, Svetlana, Benny, very helpful video thank you. You used many LEDs on one battery at the beginning, but how would you use many LEDs while still using an on/off switch for props? Hoping you read older videos' comments.

[@x3loux3338]

Tolles Tutorial, wie immer. :) Jetzt stellt sich mir nur die Frage, wo bekomme ich das ganze Zeug her. 😅 Kann ich das irgendwo im Baumarkt oder so kaufen, oder muss ich alles online bestellen?

[@grundel777]

No pues si te la rifaste valedora, lo que sea de cada quien.

[@SerkDrachenstreiter]

THAT was the helpfull video i was looking for.

[@amardeep100]

What if the battery's V is lower than LED's V will the led glow dim or battery will drain faster ? for eg If I connect 4-5 3V LEDs to a 9V battery, what will be the consequences.

[@mastakazam5094]

RESISTORS!! YOUR ELECTRICAL CIRCUIT NEEDS RESISTORS OR LEDS CAN BUUURN like the middle one 00:47

[@paranoidfurry58]

I need to get your LED book so I can learn how to do stuff, I plan to put LEDs in some parts of my Lucario themed armor. They'll be in the staff(shaped like a bone to represent the Bone Rush move it learns) and in the palms of my gloves(for the Aura Sphere attack).

[@CrimsBacon]

Oh wow! I honestly had no idea working with LEDs was this easy!

[@KamuiCosplay]

It's a lot of fun!

[@TheGhostThatWas]

The video is a bit old, but could you v(or anyone) suggest some stores where I can find leds? I don't think my local art & crafts store carries anything like this. Would home supply stores (like Home Depot) be a better place to look?

[@antonycoupe4225]

Please tell us you're going to be at MCM comicon London October 27th 28th?! 😁😁😁

[@thornstreams8649]

if anyone's of any help i'm extremely new to lighting on cosplay and electricity in general. if i were to use the exact same Leds shown in the video would 20 AWG wire be good? also where could i find switches for said wires. I've looked around amazon but since i don't know the specific name i'm scared of buying something that wont work. thank you for your time.

[@viktorhammering6102]

The 9volt battery, did you use resistors or did you use enough LED’s to make the voltage 9v? Completely new to this whole business with lights.. 🙈

[@AkinaGod]

Does anyone know where I can find lighting that can be made into a flat shape that is flexible with even lighting (IE, no intense light from source bulb, rather even lighting across entire shape)? I'd like to make a sort of arrow but have the whole arrow be a light. All I an find are LED's that have spot lighting.

[@slyer0]

very cool video. I got an question I am trying something I read in you're book of LED basics. page 32 look at my orb my orb is amazing. I have sanded the inside only because I want the outside to stay reflective.alltough not fully sure about that. anyway. when painted and with the lights on it realy shows me the strokes of the paint brush making it look very ugly. is there anyway on how to prevent this? do I need to sand it more?

[@arturmical]

One thing though: in the other props you did use 9v batteries. It's a bit hard for me as I also used one in my own, but there was a problem: I needed to use resistors so the diodes wouldn't burn out, but after that three LED was the max. four LED caused all of them to emit half the light and another one caused no light at all. Could you do a more advanced one with just how to use different batteries? It would be very helpful.

[@epiendless1128]

Just run two sets of LEDs in parallel: 3 LEDs and a resistor connected to the battery, and then another 3 LEDs and a resistor connected to the same battery.

[@kunpark1317]

can you make overwatch mei's blaster?

[@blackbeary6]

hello! I've been putting leds in my cosplays recently but I've always been searching far and wide for the right colors I want. is there somewhere that has a variety of different colors? thank you!

[@TheGomGomBoyThaiConsoleGamer]

ur e-books bundle is really cheap! wow!

[@beestheknees]

Yeah don't do the DIY spray paint top helping hand, I'm new to soldering and LEDs, I've burnt my hands so many times cause the top doesn't hold the wires firmly at all

[@OkashiP]

This is probably a stupid question, but where can I get the switches? I tried looking on Amazon but I can't tell which ones to get.

[@bravo9894]

I'm building a proton pack from ghostbusters and I was wondering how to make the cycling red lights with a small battery

[@GhostlyDucks]

Where did you get the tiny on off switch? I'm looking around amazon and ebay and I can't seem to find anything that small.

[@KamuiCosplay]

Just search for "SLIDE SWITCH" on Amazon.com :)

[@patrickmcgee7146]

Can you provide links to battery holders and switches parts? Thanks very much

[@shruumedout8471]

Where is a good place to go to get leds and wiring and all the other equipment? Trying to get into this kind of stuff for model kits I’m building but I don’t even know where to start. Thanks

[@Dacmula]

wow very useful . You earned a subscriber great job :)

[@TheConstructorChris]

I'm a little concerned this sort of wiring might result in the LEDs overloading, especially when a nine volt is attached to the circuit. This isn't detailed here. Is this a reasonable concern to have?

[@alexisasheep6554]

I'm sorry but everything is penis to me. Stupid brain, going on vacation...

[@foozzys]

honestly, hardest part about any of this? trying to find those materials, I don't even know wtf to search, lol, I can not, for the life of me, find that kind of battery holder!

[@AriesFury11]

So, this maybe a stupid question but do you plan where you’re going to hide the battery and switch before you start building or do you build then go back and cut out pieces for wiring?

[@15marieeve]

Where do you buy the LED light bulbs? :o i can't seem to find some around where i live.

[@PKTEK]

Once again, you're inspiring. I mean, look at that work station! I am beyond jealous!

[@metalgearbas4]

Sooo, with the Transpa-art, can you make a shape out of that, then sand that to make it milky and then add a LED to it? That would make it much easier to get the right shape for light accents :)

[@dakureaper8109]

How many led for the sword? beceau i need create the shoulder pads to Darion Mograine form Wolrd of Warcraft

[@BlackKitty73]

It was so easy to understand, thank you!

[@asclepius3071]

I love this but I want to do handsome jacks holster from borderlands but the thing is i don't know how to exactly assemble the leds or even get something that is transperant so the light shines through it like I'm searching through the web but I need help....and im a noob when it comes to this im good at measurements and assembling the costume like the outside details and such but not the electronics and things where you could see the light my brother used to do that for me and he isn't he anymore he left with his girlfriend so I need help :(

[@tanarisdelatormenta5498]

I got jealous of your weapons on the background :((( I want all of it (you so cool¡¡¡)

[@bronsonleiro]

Most practical LED video, Thank you, you are brilliant

[@startruckdarkness2742]

I want to make my hands glow green for a shego cosplay but this will be harder than I thought...

[@andresrodriguezperez9254]

You´re going to laugh but your tutorial is really usefull to make Custom bicycle headlights too :D

[@marylemos1564]

Would you have to create multiple battery packs for multiple lights?

[@asadfarookart]

You remind me of Emma Roberts for some reason lol.

[@zupinu2000]

Any ideas where i could buy acrylic spheres? i can't think if any place :(

[@apocryph0n]

Does anybody know what type of battery I would use for three clusters of four leds and a switch?

[@GoldRukito]

Can you shoe us how to make Glowing Part on Glove ?

[@H9O]

I know this is an old video, but what about usb leds and usb bateries? Seems easier to me, btw amazing video

[@Blueetines]

Does your book give tips on how to add sound effects to props also does it have anything in making buttons a release button

[@dodsfalle7412]

Where do you buy the switches and battery case? Been trying to look on line and have no idea what to look for.

[@bryceelischer819]

I just want my Mandalorian gauntlet with the whistling birds to light up with blue led at the press of a button

[@StalkerSempai]

Very helpful, will give this a shot on my next cosplay

[@MaximusVA_]

By THE way im a beginner and your Videos are awesome

[@alfredogarcia4102]

I am looking for better ways for next years costume for Halloween.

[@mrmesserjr]

At the moment im trying to make optimus primes glowing energon sword from Transformers (2007) any ideas on what plastic i should use? And how to make it

[@Muftitok]

Soweit Ich weiß bist du ja deutsch uhm gibt's deine Bücher auch auf deutsch wäre echt cool wenn ja würde sie direkt kaufen

[@cristian2104]

Le importaria poner subtitulos en español seria muy bueno para los que no sabemos ingles o sabemos muy poco

[@hamburgtech]

Seems like a series resistor is wayyyy overrated. If you like your leds you should use a series resistor ;-)

[@KamuiCosplay]

You don’t need a resistor for a 3V LED if you use a 3V battery. ;)

[@uncletatscreativeshack1702]

Omg I LOVE this video!! Why? Because I’m an idiot when it comes to electrical stuff and you made it super simple by breaking everything down into their simplest forms! Thank you !

[@afsmeg]

I've got a God Eater character on my list, and his God Arc does have a glow. I'm so happy I found this video!

[@vjoff1244]

Is there a different battery holder for the other kind of battery you used in the sword and the gun?

[@gutabo226]

what kind of plastic could you use for the blade of the sword ?

[@marytreasure6215]

You are so coool.... you are the best!
