Trying to add LED lights to Reaper boots.

I made these Reaper (Overwatch) boots for my cosplay and this is what I got so far.
http://fav.me/dc5bask

As some of you know Reaper has 2 sets of red lights on each boots. Sadly I have no skills when it comes to molding and wiring. Does anyone know the best way to mold tiny objects with a transparent red tint to them and have LED lights wired to them?

Once I get the lights I can finally move to painting the boots.

I'm a little unclear what you are asking.

What do you mean by the mold?

Also, do you already have your LED chosen?

Sorry I was half a sleep when I made this thread.

I need help with how to mold small parts for my boots. I also need it to be red.

The LEDs I'm using are small 5mm.

So some sort of shell insert? If so you can take a flat piece of plastic from a water bottle or something like that. Heat it up and form it to what you need. You can also get red tint spray paint from many craft stores or if you want you can use a specific type of nail polish to reduce on cost.

For the LED, do you need help with the wiring method? If so we need to know it's voltage and amps. Those two pieces of information is very important when choosing how you want to wire something up.

So looking at images online real quick it looks like the lights on his boots are basically rectangular in shape, I would look at thin acrylic that you can cut easily. You can then use red LED's with something to diffuse the color (wax paper works great for this) or you can tint the acrylic with something like Red VHT Nite Shades Tail Light Tint (you can find it at your local auto store) and then you can use red or just normal white LED's and the lenses will look red regardless of whether the LED's are on but will shine when they are.

Like Midnight Dawn said, we'll need info about the LED's you have to know what to tell you about how to wire them up. Some LED's have resistors built in, some don't, and we'll need to know how many LED's you want to have also. (This is something you will need to experiment with to get the glow how you like it.

Sorry I though all LED lights are the same.
These are the LEDs I'm using I got from Amozon
https://www.amazon.com/dp/B01AUI4VSI..._t1_B073QMYKDM

My plane is to try and put 2-3 LEDs inside the small rectangular object I want to make from a mold. If that can be done. All the need a button cell, but I was thinking if I can wire them all to a PP3 9V battery for more power.

Which of the color LEDs are you using?
One set is: W/G/B/P/UV/WW:3V-3.2V
The other set is: R/Y/O/YG:2V-2.2V

Different volts mean different math.

Your plan is doable in wiring three of them together. Depending on how you design it, it can either be powered by a button battery or a 9v. But depending on what set your LED falls under will dictate at what minimum of what battery you'll need.

Sorry. Im using the red ones.

Just to be clear. If you look at the boot to the right, at the opening below the knee cap is where I want to put the molded parts with the LEDs on both sides.

Now here is where things get a little complicated as there are many ways to do this. However it's up to you to choose which path you want.

There are two types of wiring method. Linear and parallel. If you go with linear you'll need a battery that at least produces 6v of electricity. If you go with parallel you'll need a minimum of 2v. There is a reason you have to be precise about the voltage. If too little voltage the LED won't light up. Too much voltage the LED will burn out. Most people would generally go with parallel due to it's better efficiency and easier troubleshooting if something goes wrong.

Of course you can use a 9v for either. But you'll need to add resistor components. Your standard batteries such as AAA, AA, C, and D all produce 1.5v. However you can stack them together to increase the voltage. For example if I had two AA that would give you 3v or three AA would give me 4.5v and so on and so forth.

So consider what you want from your project in terms of space management, cost, and functionality.

Going the parallel route seems like the easy way. So I'll go with that.

OK, now choose what kind of battery you want. You need a minimum of 2v. So you have a variety to work with. I.E. (1x) 3v button cell, (2x) AAA, (2x) AA, (2x) C, (2x) D, or a 9v. But if you're going to keep these on for long duration of time I'd suggest using AA as they are compact and will fit in your boot armor.

You will need to add a resistor. Depending on if you're going with 3v or 9v will determine what resistor you'll need.

Also can you read a circuit diagram and do you know how to use a soldering iron?

I'll go with 2x AA. Its very likely I'll be walking around for a long time.

I have some experience reading circuit diagrams and yes I have a soldering iron.

Just remember to bring extra AA.

You'll need 50 ohm resistors. The set up will look like this. https://goo.gl/images/uQmdvv.

Just insert the switch where you want and everything should be just fine.

Ok just to be clear. D2 is the LED and the R1,2,3 are the resistors right?

Does it matter end of the Resistor I fuse together? I ask because on LEDs this matters sense LEDs have positive and negative. and will I need 3 resistors for each LED I want or will I just need 1?

D 1, 2, and 3 are the LEDs. R 1, 2, and 3 are the resistors.

It doesn't matter for the resistors. You just need one 50 ohm resistor for each LED. So just one resistor for each LED.

I hope this helped.
