Project: Power Hoodie to the People

Project: Power Hoodie to the People

It's tough to take a clear picture of something that's supposed to glow in the dark.  Between this and Halloween pumpkins cameras have a hard time capturing the feel of it.  

Action Shot from Anime Boston 2012:
Filmed in Bluritronic Rave-o-Vision

Again not the best quality but you get the bright idea

What is it? :  An Electric Power Hoodie

How does it glow? :  EL (electroluminescent) Wire
What is EL Wire? : A phosphor coated copper wire wrapped in colored plastic tubing and powered by a small electrical charge
Huh? : It’s Tron OK? It’s basically Tron...
Modes : Off, solid, and sound activated (pulses to music see video for action)
Special supplies and instructions :
  • Bought a windbreaker hoodie on sale from Old Navy and removed the sleeves.
  • Purchased an EL Wire kit online that’s hooked to a sound sensor with a power source of 8 AA Batteries.  
  • Sewed the EL Wire to the hoodie using fishing line.
  • Both the sound sensor and the battery pack can be concealed in an inner pocket, hooked to a belt, or the wire has enough slack to reach a pants pocket as well

Hardest part of the process :
Sewing the wire into the actual hood part of the hoodie because it’s looser than the rest of the garment.  Also I hate sewing in general.  
Uses : No one’s going to miss you jogging at night with this thing on.  Also really freaks people out on a dance floor in sound activated mode.
Washable/Waterproof? :  Can’t exactly throw this thing in with a load of darks... It can handle sweat but I probably wouldn’t push it in the rain.  Wash with care.
What I learned in retrospect :
I used 2lb test fishing line to secure the EL wire to the hoodie because it’s thin, strong, and translucent.  So far it’s held together very well, and chances are the thread strength is probably more than enough.  Even so I’d probably upgrade to the 4lb strength line next time even if it’s overkill.  They also make a “clear/invisible thread” for craft sewing purposes but I can’t speak to how strong it is.  It depends on the item you’re attaching the wire to, and if you’re just going to be lounging around in this thing, or thrashing around like a fish I guess.

The manufacture called the color “fiery red” which glows mostly red with an orange tint.  Not bad looking, but not quite what I was looking for either.   I’ll probably look for just straight up “red” hold the “fire” next time.

The AA battery power source is serviceable but too bulky.  I need to figure out if I can wire it up to some watch batteries instead, or find a kit with a more streamlined battery holder.  There’s other options out there.

I’m still no good at sewing.  In a perfect world you’d open up the seams in the garment and actually embed the wire in the cloth for a more secure fit.  What I’ve done here mostly is secured the wire to the seams instead.  Effective but not as clean.

Recommendations to folks who want to try similar EL Wire projects :
Don’t be put off by electronics.  I solder about as well as I sew (which is to say I suck at that too).  So there’s plenty of kits and options out there that come with things pretty much pre-assembled.  You’ll pay a little more for the service obviously, but it might be worth the professional job.  Your fingers will be less burned as well.

From everything I’ve read if you’re adding EL Wire to clothing I don’t recommend placing the wire on anything that runs across a joint. ie running wire the full length of a sleeve across the elbow or down a pant leg across the knee.  EL Wire is very flexible but if you keep bending it back and forth the copper wire in the tubing could snap then anything beyond the break will go dark.  Like Christmas lights one goes out they all go out.

If you really want to use the sound sensor as part of the effect be aware it usually comes with a sensitivity switch, knob, or slider that you need to use to gauge how much it blinks in time with the music.  This depends on how loud the music is, and how close you are to the sound source.  In other words if you’re at a party or a dance be prepared to babysit it the whole night if you want it to blink properly.  Too sensitive and it just stays on 99% of the time.  Not sensitive enough and it will stay dark.

When trying to figure out how much EL wire you’ll need to accomplish your design cut a measured length of twine or string first then tape it to the garment.  You can even leave it on there and use it as a guide while sewing.

Aside from EL wire if you’re looking for something even more Tron-like they do make EL - Panels (squares and rectangles that glow) and EL - Tape (looks like battery powered Scotch tape). Both are flat, flexible and have more surface area so they’re more comparable to the outfits you see in the latest film.  I made a belt out of some EL- Tape that looks good.

Next light up project :
I’m signed up for a 10 mile night run at Disney World where “costumes are encouraged”.  So I’ve been drawing up plans for a glowing running outfit.  The challenge is to make it comfortable enough to run in with out damaging any of the equipment or holding me back and affecting my speed.

  1. 1) so get a camera that can handle low light!
    2) maybe you know people who sew
    3) really nice :-)
