Light-Up Butterfly Wing Tutoril, Part 2

Welcome back guys!  Now that your wings are done, it's time to make a harness.  Unfortunately, this is going to more of a walk through of how I did mine than a tutorial, because my dad helped me a bunch, and we used a few things he had laying around in his workshop.  But it should give you the general idea of how to make a functioning harness so you can make your own!

I'm not going to do a full list of supplies because some of the things I don't know what they are or their name, but I will do a basic run down of things you will need:

  • Sintra, or some form of plastic/wood plate.  This is the main back piece
  • Pipe (for wings to slide into)
  • Some form of ring for your straps to attach to
  • Screws and nails and such of various kind
  • Strap material
  • Buckle
  • Some sort of spring
  • Fishing line
  • Worbla
  • Miscellaneous attachment materials
Okay, let's jump in!  First, measure out and cut your back piece from the sintra.  I made mine fairly big, because the wings are heavy.  Also, to measure, I guessed and cut it out of paper, then held it to my back to check size.

The picture above shows my sintra plate, along with some of the materials used.  The gray pipe lying on the sintra is the first part we will attach.  My dad helped by making my rings for the straps as well as backing plates for all the attachments.  First, find the center of your piece and mark.

Lying on my mark is one of the backing pieces my dad made for me.  In order to attach the pipes, I used a copper attachment with the same diameter as my pipe.  Using the backing plate, I marked then predrilled holes.  I used two copper pieces and overlapped the center hole.  Use a T square or an L shaped ruler to make sure your pieces are parallel to the top of your sintra.  I placed my pipes high, simply because that's where I wanted them.  I wanted the wings to look like they were coming out from between my shoulder blades.

 Once your holes are drilled, attach using screws, backing plate, and bolt.

Next, you need to attach your rings.  My dad made these for me because I couldn't find exactly what I wanted.  Basically, you do this the same as the pipes.  Set out on your sintra, mark, pre drill, and attach.

Now, all those screws are going to be sticking into your back, so I recommend padding it using EVA foam.  Use your harness as a template and cut out.  Press your back piece into the foam to mark your screws.  And dig those in a little.  I just melted them a bit with a hot glue gun tip.  Attach using glue (I used E6000).

Now, straps!  Measure out how much you need for one of the back pack like straps.  Cut slightly larger than that (at least 4" larger).  Attach to top ring.  Hold pack on (use help) and measure where it needs to attach on the side.  Sew that.  Repeat on other side.  For the bottom strap, I attached two separate straps to each side, then a buckle.  Make sure it's tight.

Use worbla to create a battery holder.

My dad used some special type of screw that goes into metal and secured the worbla for me.  On it's own, it might hold up with glue if you are really gentle with it.

Now, it works as is, but your wings are going to be very free floating.  I recommend you attach some fishing line to the wings, the make a hoop for you to hold on to or attach to a small piece of wood.  That will give you some control.  You can also install springs to force them back when you aren't pulling on them.  This part, my dad and I just scavenged his workshop at home for parts.  Basically, you need to attach a spring to the wing, then somewhere it can clip into on the sintra, that way your wings can come out of the harness.

And you're done!  Congrats on the new wings!

Predator BioHelmet LED laser DIY

Alright guys, if you have been following my Predator tutorials/walk through's then you have a biohelmet without a laser site!  Time to fix that!  I want to preface by saying I am in no way an electrician and I certainly may have done something incorrectly.

You are going to need:
  • 3 LED's in the color of your choice (I used red cause it's what I had... wanted to use purple though)
  • Resistor (use online Ohm calculator to find out what kind)
  • Extra wire (might not need this, but it's good to have on hand)
  • Soldering iron and solder
  • Electrical tape
  • Plastic washer of some sort (got mine from the plumbing section)
  • Battery connector
  • Worbla
  • Hot glue gun with glue
Okay, so first, you need to drill your holes for the LED's into your biohelmet.  Since this was my first sculpt and cast, I didn't get the sizing right, so I drilled three small holes and put my LED's up to the hole, but now through it.

This is what it ended up looking like.  Don't worry, I'll explain how I got to this part.  Once your holes are drilled, make a paper template of your holes, as well as your circuit (I placed the paper over my site and marked with pencil where the holes were).  YouTube has been a life saver on this Predator build.  I scoured YouTube and watched roughly a bajillion videos on how to do LED lights.  It helped give me a bit of confidence.  Also, my dad helped a lot.  :)

Things to note:  On your LED individual pieces, there is a long end and a short end.  Check your supplier, but typically the long end is positive, the short negative.  I drew out my circuit, just as a helpful reminder of where everything goes.

In the first image, you can see my plastic washer thing.  I used my paper template to mark the holes on the washer.  Then, held it in place in my biohelmet and made sure everything lined up.  Then, I drilled the holes.

Once your holes are drilled, shove the LED's through.  Then, bend the wires so the + are together and the - are together.  Do not let the + and - touch each other.  They need to be separate.

Solder your wires together (+ and -, separately).  Your resistor goes on the positive side.  Solder in place.  I used hemostats to hold everything in place while soldering.  They are terribly good conductors of heat, however, so I burned my fingers a few times.  I'd recommend using something with some sort of insulation.

Strip the wires on your battery connector and attach + to + and - to -.

Test!  Make sure everything works.  If it does, wrap everything in electrical tape, making sure to wrap the + and - wires separately.  If they touch, you will get a short.  My dad said you don't need to wrap the - end since it's a ground, but I wrapped mine anyway to be safe.

Once everything is wrapped, install.  I held mine in place and just squirted some hot glue on it.  Make sure the glue doesn't seep out the holes, or onto the LED (it'll dull the light). 

I then made a battery pack out of worbla and attached to the crown of the biohelmet.

Paint that, and you're done!  See, LED's aren't that scary!  And the finished product:
