Hello,
Here is another Helmet that I have been able to modify with some LED lights. This Helmet is something that I had previously created for a Sci-Fi film a while ago. (So I don't have instructions on putting the helmet itself together... sorry) but adding some cool looking "chasing" LEDs is fairly simple to do.

Materials required:

All oft the LEDs, Connectors, Color Controller, and Battery (Basically everything for the lights) I was able to get from www.elementalled.com. The links attached to the materials list will take you to the corresponding page on their web site.

(1) foot of Solid Color (Purple) LED Strip Light
(6) Inches of Flexible Side View LED Strip Light (Amber)
(1) High Power RF Color Controller
(1) Rechargeable Li-ion Battery Pack
(1) 16.5' RGB Extension Cable
(1) LED Adapter Splice Cable
Hot Glue
Soldering Iron
Electrical Tape

Step 1: Wiring the Positives

This is where we will be connecting the positive power line to the strips. The positive line will always be running through the lights, but they will not light up until the negative power comes in as well.

a) First take your foot of Purple LED Strip Light, and cut off (3) 2" Strips. (Cutting on the cut mark of course)

b) Then cut off (2) very short segments of Black wire from the 16.5' RGB Extension Cable.

c) Using your Soldering Iron, solder the short segments of wire to the positive solder points between strips one and two, and between three and four.

d) Then Solder a longer Black wire to the positive solder point at the beginning of the total fixture.

This will be the start of one full segment (ear) of chasing light for the helmet. For my helmet I did this twice. (Once for each "ear")

Step 2: Wiring the Negatives

Now we get to the wires that will control the pattern of the lights. The negative lines will be soldered onto each 2" section individually. When power is sent through these, along with the positive line (which is always on) the individual sections will light up. (More on this later)

a) Solder a long red wire from the 16.5' RGB Extension to the first negative solder point on strip 1

b) Solder a long green wire from the 16.5' RGB Extension to the first negative solder point on strip 2

c) Solder a long Blue wire from the 16.5' RGB Extension to the first negative solder point on strip 3

Step 3: Controlling the Lights

This is where we get to the pattern controls. This is what I think is the fun part.

a) Take the two positive wires from the two "ear", and connect them to the positive connection on the Color Controller.

b) Take the matching Red, Green, and Blue wires from the ears, and connect them to the corresponding negative connections on the color controller.

c) Cycle through the 25 separate modes to find the pattern that you like. (I use either 8-Three Color Jumpy Changing, or 12-Three-Color Running) *This will require power to be run to the color controller. This will be explained later.

Step 4: The Visor

This part in comparison is quite easy compared to the chasing light we did earlier.

a) take the 6" of Amber Side view LED Strip Light, and solder a wire (I used Blue) to the positive, and a wire (I used red) to the negative.

b) cut a small hole next to the visor, and run the wires through.

c) Mount the strip light so that the lights on the sideview strip are pointing down toward the visors "glass"

d) Connect both of these wires to their respective positive/negative connections on the incoming power screws on the Color Controller. (Picture #2)

The power coming into the Color Controller will split between the Color Controller, and the Visor Light so that the visor will always be "on."

Step 5: Power

Now we get to power up the helmet!

a) Take the LED Adapter Splice Cable, and wire it to the power connection on the Color Controller. Matching positives and negatives once again.

b) Plug the other end into the Lithium Ion Battery.

c) Turn the battery on.

Voila! Let there be light! Now it's time to get out there, and hunt some aliens!
