What's cooler? Lasers.
What's awesome? Fire fans.
This instructable was inspired in part by fire fans and in part by the bionic ballerina.
Each fan is made of five fiber optic rods, lit by tilt sensor to be red or yellow, and two lasers.
I have a video below of the fiber optic part working, but my camera isn't nice enough to give the full effect, especially the lasers. You'll have to trust me that they're awesome.
This is part of a light-up dance costume that goes with the dazzle jacket and lightcatcher dress. The costumes are intended to aid self-expression and augment the inherent drama and design of the dance costume.
Laser fans allow the dancer to transform any dark place into a dance floor with their visible beams, immersing the audience in the experience. The fiber optic rods, which can be used independently of the lasers, highlight the area close to the dancer and the dancer's specific movements (the dancer can interact with the fans by flipping them to change their color). Without the lasers, the fiber optics create an intimately lit dance space on a dark stage.
Step 1: Materials
cutting mat (for use as a material)
heat shrink tubing
super bright green laser pointers (these ones are awesome, though they take a very long time to get here)
button cell battery
vertical band saw
hot glue gun
Step 2: Cut Fiber Optics to Size
Step 3: Prototype Spread
Step 4: Cut Up the Cutting Mat
If you're cleverer than I, skip ahead to step 8. Otherwise, if you don't have your lasers yet, carry on.
Slide the rods in and position them to preference. Secure with hot glue.
Step 5: Make Your Circuit
Step 6: Heat Shrink LEDs Together and Onto Fans
Solder together all of the reds, all of the yellows, and all of the grounds as shown. Solder tilt sensor accordingly.
Step 7: Position the Whole Circuit
Step 8: Drill the Holes for the Lasers.
Drill the larger strip of cutting mat so that the laser just fits through. I used a sheet metal step drill to hand-do the last little bit to ensure it's tight.
Drill the smaller strip so that the laser can sit comfortably.
Work the lasers into the holes. Glue the base if necessary (but don't glue both parts of the laser!). If your big cutting mat strip happens to be at button-height on the laser, then you can turn the lasers on and off by sliding them in and out of the holes. If it's not, electrical tape the button down and unscrew the battery compartment until it turns off.
