LED help for light up Iron Man eyes?

[Coolguy26]

So i recently finished my iron man helmet and i want to set up some led lights.
Im really new at setting up LED's so i need some help.

So i have a 9 volt battery, 2 white 5mm Leds, and a small switch.

The leds are 25ma, and 3.3v. I need to know what resistor to buy for that specific led.

And i specially need a wiring diagram for everything including the switch, so i can set it up and still be able to adjust in the helmet.

Thanks in advance.

a single 100ohm 1/4W resistor should work just fine


What you would do would be like this:

battery(positive)----switch ----led---led--- resistor---battery(negative)


Hope that helps

This was one of the things i was wondering about as well, thank you. Im currently waiting on the updated version of Darkside501st mark vII and trying to get everything together. This helped =)

Have you thought about using EL sheets/strips?

 

[Finnlock]

Thanks neomage, that was strait forward and easy to understand.

 

[neomage2021]

No problem. good luck on your project!

I would use EL tape. Here is a pic the painted helmet is using LEDs and the unpainted one is using EL tape, it is as thin as paper and the light is constant all across. Just a thought.

EL is nice and even color but not as bright as LED. i still prefer LED cuz i like to be bright. i put 6 LED per eye.. soo 12 in total

Here is a link to a LED series parallel array wizard. Just input the information on the LEDs you are using and the wizard will tell you what resisters to use.

just out of curiosity, what are you guys doing as far as eye shielding goes? because as cool as the LED lights in the eyes would look, having them directly in front of your eyes for several hours would probably be harmful to the eyes.

MadHatter250,
Normally there are two techniques to make IM eyes: direct and indirect light.
The picture shows basic idea on how to place the light source (LED or EL or whatever). Variations can be done from this.
None of them is directed to the eyes of the user.
LED is a very homogenous and direct light. It would be bad if you have it leaked (specially direct leak) into your eyes, considering the distance too.

Place it right you have no problem at all.

Hope it helps.

I made diffused mesh lenses for mine which light up, and you can see through:

I also have an electronics tutorial series which covers calculating LED/resistor values and controlling servos etc: XRobots.co.uk - Electronics tutorials

XRobot,
So you're the one that suggested bridal's veil.
It was your idea that I came up with the idea of using PWMF sticker.
Thank you.

Can I put your link in my tip's thread?

 

[XRobots]

Yes, it looks like I first did something similar in 2009:

Yep - you can put links to my stuff anywhere ;-)

This is Awesome!! I can use this on mine! Thanks!

Hi guys

I've just started my ironman project and need to install eyes, does anyone that actually has electrical general knowledge help?

Is there a diagram to light up the eyes when helmet is shut?!
Someone did say to me to put magnets on bottom of face piece and magnets on top jaw so when they connect they light up.

I've tried this and failed miserably as I'm useless with anything electrical but it seems a very good idea so keen on this.

I used a magnetic reed switch like this:

Attach the loose magnet to the bottom of the jaw of your helmet so it sits just below the lip where the faceplate sits when closed, then wire up the half with the wires into your circuit. When the two sides get within proximity to each other the magnetic force closes the circuit and the lights will light up. You can boost the strength of the magentic force of the loose magnet piece by adding more extra magnets to it, just in case you may have to put it too far away for it to activate the circuit.

Your a legend, cheers fella

Visit my thread on tips (link below).
You can use pressure switch or magnet for simple set up.
There is also a diagram for dip LED and LED strip connection.
If you need more help, let me know, good luck

Stupid question: does one half of the switch get wired to the battery? I don't understand how it all wires up to the lights.
